My press has a spot about half way on the down stroke that gets tight. Just about the time it hits the location pin. Feels like it’s hitting a undersize hole or is off center a bit. Is this normal or is your press smooth throughout the cycle.

That does not sound normal. I do not experience that.

no felt tightness in my machines travel up and down

Like other members posted, I do not experience/feel tightness as carrier approaches index/"location" pin and ram moves up and down smoothly.

as the driver clutch gets to the twist in the index rod and does its 60 degree turn to rotate the driven clutch/drive bolt/shell plate on the way down and rotates back on the way up but it is clear of the driven clutch. When the driver clutch is in the straight sections of the index rod there is no felt "tightness" and no movement of driven clutch. This does happen just before the index pin enters the shell plate on the way down and just after shell plate clears the index pin on way up. On the way up you can see slight movement of the index rod where it is held down by the breech lock bushing on top.

This is correct as index/"location" pin enters the carrier:

• As ram moves down, index pin enters carrier core
• Cross slot at bottom cover riding the flat index bar does 60 degree counter-clockwise turn while engaging the gears indexing the shellplate
• After shellplate indexes and held by retention ball/spring tension, index pin enters hole through the shellplate
• As ram moves up, index gears disengage (shellplate does not index moving back up) and as soon as shellplate clears the index pin, it "free floats" and can be rotated in both directions

Don’t know why I didn’t think of the indexing rod before but, I removed it and cycled the press

If you are feeling this slight additional indexing resistance, that is normal. To rule out if the "tightness" is from indexing, remove the index bar and move the ram up and down. If the "tightness" goes away, it's due to indexing and we can look at the indexing parts. If the "tightness" doesn't go away, keep on reading below.

Could feel the pin move ever so slightly as it contacts the plastic cover

Has the carrier core ever been removed from the ram? If yes, then carrier may be off alignment and hitting the pin as it comes down. Inspect the pin for significant contact/wear marks. If no and index pin shows obvious contact/wear marks, then contact Lee Precision customer service.

After checking the linkage found it was what I call sloppy loose. Tightened it up and it was worse. Decided to pull it apart and look at everything, found a couple of problems. First is the location pin was hitting the slot cut into the carrier by about .010 so small tap with a brass hammer and it’s a lot closer now. Not perfect but loads better.

Now on to the linkage, why is tightening causing it to get wonky. Loosening it up a gets better so slowly tighten each bolt and found bottom ones were twisting the linkage out of wack. Finally swapped sides on the bottom pieces that move the ram up and down.

Press is now working right, can hear a light ping when carrier is raised. I can live with that

Forgot to say thanks for all the help.

I think this was a classic case of tolerance stacking.

Again thanks guys

Nice.

That "ping" you hear is the self-adjusting zero index working ... It's normal.

I offered to do some "real world" point-of-failure stress test using Accurate No 2 and other small granule powders with the new redesigned priming pin to Calvin and got this email:

We will send one out. Should go out today.

Have a great day!

What is self-adjusting zero index?

Normally, shellplate index timing to die alignment is done by making small screw adjustment in Lee's previous presses.

Starting with Auto Breech Lock Pro/Pro 4000 and Six Pack Pro/Pro 6000 (That replaced Load-Master), shellplate index zero employs new design that eliminates the need for shellplate index timing adjustment.

If index pin does not line up with the holes in shellplate, you simply rotate the "free floating" shellplate and as shellplate drops down guided by index pin, shellplate timing automatically adjusts so on next cycle of ram, shellplate index timing is zeroed.

That is a new one on me, have not heard it in loading or dry cycling operation.

You won't hear this slight "ping" noise when the shellplate timing is zeroed. It only makes the noise when auto-adjust is working to zero the shellplate timing.

Understand the Load Master fully. Do not know about the "screw" on the others, but it is inconsequential.

If carrier is moving down the driver clutch is engaged to the driven clutch, even before reaching the twist in the index rod just by friction of the driver clutch on the index rod when moving down, and rotating the shell plate by hand will make a noise I am sure, slight movement up should disengage the clutch to "free float" I assume, to facilitate hand rotation of the shell plate without clutch engaged. In testing my index rod with the driver clutch it does not just fall down the index rod, there is still some friction on the cross even before reaching the twist in the index rod which would force it up firmly into the driven clutch and actuate the shell plate.

You won't hear this slight "ping" noise when the shellplate timing is zeroed. It only makes the noise when auto-adjust is working to zero the shellplate timing.

Yea, I cannot get the "auto-adjust" ping through my thick skull. Unless it is the forcing of the driver clutch to ratchet on the driven clutch which makes the noise.

I fully understand the "auto-adjust" capability of the driver clutch to line up its many teeth with driven clutch when one has rotated the shell plate by hand.

Anyway.

I will sleep on it.

Thanks

The “pinging” noise I believe is simple harmonic’s. Locator pin is not perfectly centered in carrier slot, off by a few thousands. When on the up stroke as the pin clears the carrier is when it happens.

Think I’ll try a few more taps and hopefully it will hit the sweet spot.

My advice, for what it is worth, would be to discuss this all with Lee and see if they will take it back and make it right.

We heard of one core falling off, one alignment issue damaging cases and this might be a case of their issue with the process of assembling of the core to the ram which took some work to perfect by their own words. If tapping moves it, it sounds like a problem considering the high torque on the set bolt attaching the core to the ram.

With all of the others of us owners which do not have this issue, you should not either. Many issues can be field addressed, this one sounds different.

Just my humble opinion on what I think I understand.

Well now I have a real problem, I am out of bullets. So out to the casting, powder coating table in the garage and get busy. After getting all the updatied parts installed my SPP is running perfectly. I am waiting on the new primer pin just to have it (just in case).
I need to bone up on supplies plus empty a bunch of cases so in can use my new press. Wooo hooo!!

I think we are talking about different noises. The noise auto/self-zero shellplate indexing system makes when it is adjusting is made during down stroke of ram after shellplate is rotated manually so the index pin enters one of holes in the shellplate. Same noise was made on Auto Breech Lock Pro and other presses as indexing system adjusted.

If you are hearing the "ping" noise during up stroke of ram, it's not due to the indexing system as gears disengage as soon as carrier/ram moves up. As you posted, it could be the bent index pin springing back as the carrier clears the pin tip.

How much movement do others have in the top part of the connecting link that attaches to the body of the press. I have been feeling some sudden movement when on the bottom of the down stroke of the carrier. I started checking to see what it was and discovered that the top part of the connecting link had very noticeable moment up and down. I would estimate around 1/32". I then loosened the bolt so that was no pressure on the link and it is a very loose fit on the bolt. If I do not tighten the top bolt and just have a snug fit I do not feel the movement but it is there and I can visually see it. I have had that bolt fairly tight and I think the movement was sudden when it overcame the friction. Also Curious as to why Lee chose to use a bolt in this position instead of a link pin like they do on the bottom. The bottom pin and link have no noticeable movement like the top.

 

[LiveLife]

If you tightened your linkage according to Lee Precision factory video and still have play to where you have sudden movement, you need to contact Lee customer service.

• Bottom linkage: Center spacer is installed with wavy washers facing out and tightened with 5/8" nuts to allow movement (Recheck nuts on regular basis and re-tighten is loose)

• Top linkage: 11/16" lock nut goes on left of 5/8" bolt and after making it full tight, back off half a turn to allow free movement of the bolt

Six Pack Pro: Replace Bottom Cover

Tools required:

• 1/4 hex key
• 1/2 wrench for the lever
• 11/16 wrench for the link pin
• 5/8 wrench for the nuts
• Phillips screwdriver

1) Remove easy lock bushing that holds down index rod. Lift out index rod. Unhook the primer feed spring. Remove the primer tray, primers, and powder measure from press.
2) Remove the red tool head by loosening the (3) socket head cap screws with 1/4 hex key. Lift off tool head and slide case feed slider off rail.

3) Remove the shell plate, rotate clockwise with ¼ hex key to loosen.

4) Remove lever by loosening up hex head bolt with 1/2" wrench to release the lever clamp from the sleeve.

5) Loosen and remove nut on right side of the link pin with 11/16" wrench, loosen but do not remove the left nut.

6) Loosen and remove upper linkage bolt with a 5/8" wrench on the head of the nut and 11/16" wrench on the nut. Remove hex head bolt, spacer Remove primer disposal tube. Remove upper linkage nut and bolt. Remove connecting links. Inspect the ram, there may be a burr at the toggle attach point. Gently sand off burr with sandpaper or file.

7) Unscrew the two sheet metal screws on top of the carrier with Phillips screwdriver. Lift ram and carrier assembly up and out of the press base.

8) Unscrew the one pan head screw with Phillips screwdriver under bottom cover to remove bottom cover. Slide out primer pin and replace. Remove driver clutch

9) Slide on new bottom cover.

10) Install pan head screw with Phillips screwdriver on bottom cover.

11) Slide ram and carrier assembly back down into the press.

12) Re-attach linkage.

• Install spacer and center.
• Tighten upper linkage. 11/16" wrench on nut, 5/8" wrench on head of bolt. Tighten completely, then back off ½ turn so it freely rotates.
• Set tension appropriately to activate your press lever.
• Re-attach handle Tighten hex head bolt with ½ wrench.
• Install the two sheet metal screws with Phillips screwdriver inside the carrier.
• Raise carrier, install shell plate. Rotate ¼ hex key counterclockwise to tighten.
• Re-install the 3 socket head cap screws with ¼ hex key.
• Re-connect primer feed spring to tool head. Hook open facing away from operator.
• Install index rod. Install smart lock bushing to retain index rod.
• Re-install case ejector.
• Cycle press lever to verify.

If I tighten then loosen I don't feel the movement but it is still there. I am curious as to how much play others are seeing.

I have some play.

I tightened the lock nut then loosened until I could move the bolt freely.

Curious as to why Lee chose to use a bolt in this position instead of a link pin like they do on the bottom. The bottom pin and link have no noticeable movement like the top.

The ram/linkage/lever came straight from the .50 cal BMG Classic Cast press.

Bottom linkage uses "spacer" with threaded ends. If bolt was used and tightened too much, it would pull/draw in the linkage bars in.

And top linkage uses bolt with lock nut so as to have some play and free movement of the bolt to allow the linkage bar ends to move.

I tried the method they stated, tighten then back off 1/2 turn, way too loose for me. I ended up with about an 1/8 turn back off, movement but not felt like before. I had it way too tight before according to their directions.

I have the Classic Cast press and just compared the 2, yes same except the Classic uses pivot pins on the top.

Bottom linkage is similar to the Load-Master.

I wish Lee would put out some more detailed instructions then they do or at least have them on their site.

When I removed the linkage when new to clean and lube I backed it of at least 3/4 turn, possibly more to get rid of any friction between the side of the linkage and base plate. Operating very smoothly and easily now, so much so the case slider spring, primer sider spring and primer pin spring will push/pull up the carrier a little when letting go of the handle when at the bottom. Have not seen the movement you mention, there is some play side to side, maybe 1/64" though.

Thanks to member @Gillie Dog, we have an issue/resolution identified for SPP/Pro 6000 - https://www.thehighroad.org/index.php?threads/lee-6000-press.905987/page-12#post-12454985

On the primer slider channel/trough, there are four (4) tabs that prevent slider from lifting out of the channel/trough. But the spring end can contact/snag on the tabs to prevent smooth sliding of slider and make clicking noise. Using pliers, I gently narrowed the spring end (while ensuring there was enough opening to clear the slot where spring end slides down into). Now primer slider slides smoothly without making noise.

I found a much simpler fix for Lee to stop the first tab from interfering with the return motion of the primer shuttle. All I did was use a riffler file to slightly round the sharp offending corner on the first tab, and the spring doesn't even know the tab is there.

I had not previously got around to doctoring the spring, so tonight I had a close look at what caused the problem.....one sharp corner was all. Took about 3 seconds. I didn't really want to modify the spring because it's not that easy full width to find the hole in the shuttle it goes in as it is and hold your mouth just right to get it in.

I would think Lee might find this more palatable than modifying their existing stock of springs. Just one bump of the one corner with a dremel, is all it takes, and the problem is gone. At least it's another choice for them.

 

[LiveLife]

So to install the new priming pin I had to take the case feed spring off, I put the spring/screw in the hole closest to the press "front hole", but was unsure how far in/out from the case slider block it should go. The hook over the screw before I took it apart, was vertical, I can't get it back to that position, mine is canted a bit.

Spring end just needs to hold onto the screw so you just need to tighten a few turns. And don't worry about spring end cant as I tested both ways and it really didn't make much difference. As for the placement of the screw, the front hole is the correct one.

During this session, there were 5 or 6 cases that sort of shot out ..i.e. they didn't slide. It had to do w/ the spring, but I'm not quite sure what was causing it.

Unlike Dillon 550/Hornady AP LNL shellplate where case base slides unto the top of subplate, Lee SPP shellplate actually captures the case base (Like Dillon 650/750) and shellplate with case together "free floats" on top of the carrier cover that gets screwed to the carrier core. So check to see that the shellplate is not loose as misalignment of case slider surface and shellplate can cause the case rim to snag and not slide into the shellplate freely.

ETA: Thanks to @9mmepiphany, clarified shellplate differences

The seating was pretty consistent 1.143" - 1.144" was probably 90% of them, there were a few 1.142 and six or so 1.145". That's probably just as good as my 550B.

Great! During my OAL consistency testing, SPP demonstrated it was capable of OAL variance down to .001"-.002" depending on the headstamp of case using mixed range brass. Consistent enough for "match grade" round production.

So Lee sent me 2 new priming pins/springs. When I requested them, that was the day before LiveLife posted Lee was changing them up. The two pins they sent me were different in one way from the original pin that came w/ the press. The collar the spring rests on was thinner, about 40 thous thick, the original pin that collar was 60 thous thick. The OAL, the pin diameters at the face and tail end were the same. The new ones were ever so slightly more rounded on the face, but nothing extreme.

If you can't decide between the two, I would insert them in deprimed primer pockets to see if any sticks and use the one that doesn't. If they both work fine then flip a coin.

I didn't really want to modify the spring because it's not that easy full width to find the hole in the shuttle it goes in as it is and hold your mouth just right to get it in.

I would think Lee might find this more palatable than modifying their existing stock of springs. Just one bump of the one corner with a dremel, is all it takes, and the problem is gone. At least it's another choice for them.

Too late. Apparent decision was already made and new gray colored longer primer slider (that eliminates the black hold down piece) is being shipped with spring end that is reshaped/smaller to not contact/snag on the four tabs of the slider channel/trough.

I actually agree with this decision as your solution applies to one press while using smaller/reshaped spring end solution applies to all the presses due to slight manufacturing tolerance variations that can stack to allow the spring end to snag/contact the four tabs.

The smaller spring end does make it a challenge to slip the opening through the slot in the slider end but if the spring no longer gets crushed/damaged, then there is no need for replacement.

 

[GW Staar]

I wasn't referring to the lifting problem.....just the bump caused by the sharp corner. The longer shuttle already fixed the lifting problem.

Problem: Primer chute/trough pin does not contact the groove rings on press column enough to shake the primers down in tray - On my press, the pin contacts the upper groove ring but not the lower groove ring. After thinking about bending the pin and zip tying the press column, came up with a simpler more elegant solution.

Solution: Make sleeve roller for the pin from a pen filler - I looked around the house looking for a sleeve material that could work as "roller" for the pin and found the pen filler from Paper Mate was perfect fit as it was slightly loose fit enough to be a "roller" for the pin.

NOTE: If you use a pen that is not retractable and use a cap, then the pen can still be used for writing even though you cut off the end of the filler tube

I made a clean cut slightly shorter than 3/4" (11/16" actual)

After moving the ram to put the pin in the lower groove ring, I inserted the pin through the "roller" and now it makes contact with the lower groove ring and shakes the primer tray better with the upper groove ring.

I did this to mine and it helps but I am still having problems with the primers not feeding out of the primer tray. I have to watch the tray and occasionally give it a thump with my fingers. I need to find something that put a little more pressure on the tray.

Problem: Priming chute/trough pin does not contact the frame column groove rings enough to shake the primer tray

I did [the pen filler sleeve roller mod] to mine and it helps but I am still having problems with the primers not feeding out of the primer tray. I have to watch the tray and occasionally give it a thump with my fingers. I need to find something that put a little more pressure on the tray.

Solution: Rotate the top carrier cover counter-clockwise when tightening the two flathead metal screws while ensuring the priming rod/pin moves up and down freely.

When the two top carrier cover flathead screws are tightened, if no attention is given to where the pin is in relation to the frame column/groove ring, then top cover will be tightened with pin not contacting the frame column/groove rings.

To prevent this, when you tighten the two top carrier cover flathead screws (while holding the bottom cover with your hand), see if you can place the primer chute/trough pin in the lower groove ring by torquing the cover counter-clockwise before tightening to put more pressure on the pin (But ensure the priming pin moves up and down freely).

With the pin closer to the frame column/groove rings, adding the DIY pen filler sleeve roller mod will help shake the primer tray better (Also, if you have additional trays, try others and use the one that moves the primers to chute/trough opening the best).

When I torqued the top carrier cover too much, I noticed binding of priming rod/pin to not move up and down freely (because bottom cover is held captive by the ram), so I backed off the torquing of top carrier cover but that resulted in the pin not contacting the bottom groove ring (pin contacted the top groove ring fine to shake the primer tray). With the DIY pen filler sleeve roller mod for the pin, it now contacts the lower groove ring as well and contacts the upper groove ring to shake the primer tray more.

When John Lee redesigned the priming rod/pin, he may not have realized that reshaped rod/pin could be addressing another issue of primer tray not shaking enough due to pin not contacting the groove rings and I will be testing that when the new priming pin arrives. Stay tuned.
