Question for Triumphoholics

I'm working on my son's TR6, which had the misfortune of being flooded in sea water, but I find that the differential is surprisingly undamaged. The gears and bearings seem to be in perfect condition, but I need to replace the pinion seal. It is one of the later diffs (GD 65XXX) and so I presume it uses the crushable bearing spacer.

Question: If I pull the drive flange to replace the seal will this require replacement of the spacer, and if so, can that be accomplished without removing the differential carrier?

Any advice will be appreciated.

Check your manual, Bill, I believe there are instructions in there for doing just that. As I recall, you have to mark the position of the nut and return it to that position, but it would be best if you check the book.
 
I've fooled with only 2 differentials and both of those had the type of flange nut (castled?) that used a safety wire, not nyloc nuts, and had the non-crushable spacer.
So you just tighten the nut and find a hole for the wire.
If there's any doubt about the type of spacer that you have, once you get the old pinion oil seal out, that whole pinion "assembly" will be free to remove thru the opening, for your inspection.
 
Well, my apologies. I know I've read somewhere that you can return the nut to it's original position without having to replace the spacer; but that information does not appear to be in either the TR6 or Stag workshop manuals. And the Moss catalog notes that the spacer should be replaced every time (which means having the tool to measure the preload).

Possibly I'm thinking of the spacer in the rear hubs instead of the diff.
 
From what I've seen, if the non crushable is used there are shim washers that have been used to get the correct preload. But unless there's been other work done that would alter the preload, I don't see why the same shims couldn't be reused.
Again, this only applies to the non crushable spacer. If it's the crushable spacer, don't reuse it. Replace it or convert to the non-crushable spacer and get a pack of shim washers.

Randall, mine has been done like that and it's fine. I don't know if it's written anywhere, but it works.
