Newbie with 915
Posted: Sun Oct 01, 2017 10:34 pm
Just took apart my 915 transaxle for the first time..
It had been 'gone through' by a shop,
But I had little confidence in them.
Thinking it was a good thing I did so.
The shim that controls the pinion depth,
Right under the bearing housing (That's what you call it, right? ) Was a bit mangled.
The only part of the shim that was really damaged was where the pinion bearing interfered.
Perhaps during a previous disassembly..?
It looks like the 'functional' part of the shim,
Where it controls the pinion depth, is OK.
Maybe I could trim it up a tad, clean it up, and run it?
Not that I'm trying to save money,
But I'm scared of messing things up.
Is there any particular story about replacing this shim, besides getting the right thickness?
Measuring it, it comes in around .0043"
But, because of it's crusty condition, it could be a few tenths more, or less..
Let sleeping dogs lie?
Signs of impending doom?
Hoping this isn't part of some expensive self-destruction scenario..
The races (especially pinion bearing) seem really tight in their bores, FWIW.
Will need a rebuild gasket set, O-rings and output shaft seals.
Who would you get these parts from?
Any wisdom from the old guard would be most appreciated.
Feeling a bit 'in over my head'!
