Yes, the arbor is torqued into place, then the barrel assy should be installed with the wedge driven in. Next, an oversized staking pin is driven in to lock the arbor in place. Trim the pin, file it flush with the frame. The arbor will be flush with the frame as we!! If the arbor is new, it may need some minor filing to get it flush.

The 1858 Remington pattern – Steel frame and the less expensive brass frame examples of the finest percussion pistol ever made. It is said that soldiers returning from the Civil War elected to purchase these revolvers at a rate of 2 to 1 as compared to the 1860 Colt Army. ( Guns America Digest )
It is articles like this and follow-ups that helped me decide on Remington.
I have read quite a few complaints of loose arbors but not any guns coming apart except over the wedge issue. About the only complaint I read of remingtons is fouling , which is a problem , and grip. But colt’s foul too if not as bad.
My questions about the arbor is concerning strength. The arbor it’s self is pretty stout, granted, but how it fastens seems like a weak link to me. The threads are over sized, the lug of the arbor does not have the same diameter as the arbor, and it all comes down to a what ? a 1/16th stake-pin? While I don’t think there is any danger of the gun coming apart , if the cylinder is misaligned enough couldn’t it explode the gun when fired ?
Anyway it seems to work good enough that there is a large diehard following for colt’s. My point is that the arbor is not the guns strength, as beefy as it is, and if all five threads engage with five threads in the frame it is a good joint, but if not the gun is weaker still. The solid construction frame does not need the beefy arbor because it is inherently stronger and I have not seen any complaints of cylinder pin trouble. Given the same grade steel. The molecules are bonded, not jointed and screwed together.
I still have not run across a Remington complaint similar to yours, only that it is stronger by every source or mention I have found. Conversely, while colt owners are extremely loyal , I find complaints about the wedge, the loading process, sights, loose arbors, and it’s over engineering.
