Installed my pinion shaft with a new seal and bearing , inner bearing was ok . Used the 3 metal shims that were on when I pulled it apart . Paper shims fell apart . Snugged up the 4 cover nuts and now the shaft is hard to turn . I figure I need more shims . Can I just use the extra metal shims I'll have when I pull the final off that's still on my D 15 ? Should say I'm working on my donor final that's on my bench . THANKS !

I have used just steel shims.. I wipe a VERY FINE RTV or Permatex on the face of one shim to seal against the next... your talking one thousandth thick..
If you dont have sealer or paper between the steel, you MIGHT have oil weepage over time.. Not leaking out, but stains on the new paint. ..... you might be able to use head gasket shelack or similar.. i have never tried that.

you can also cut your own shims out of paper if you wish.. About anything will work... typing paper / computer paper would be fine.

Brown paper sacks work the best. They cut easy and hold the oil. HTH Tracy

I’ve used paper as shims there too, worked fine.

Made a gasket from some gasket material I had . It's a little thicker than the 3 metal shims . Seems okay to me . Thanks everyone !

If you were able to turn the pinion shaft by hand before (your description) but hard, all you probably needed to do was split apart every shim you had, smear RTV on both sides of every shim, reassemble and snug the bolts up so the excess RTV oozes out and STOP. Let it cure for 24 hrs and then tighten the 4 bolts and I'll bet your bearing setting would be snug, but turn easily by hand. What I think you have now is a loose setting. You should have taken a block of wood and put it up against the splined end of the pinion shaft and directly smack it really hard on the end with a 4 lb maul 3 or 4 times. I'll bet after doing this, you'll find the pinion shaft is now loose from adding too many shims.

So you took out the 3 metal shims and replaced with one gasket ? That might be OK... Mike the 3 shims and compare to the thickness of the gasket material. Like Dr said, you only need a few thousandths.

Have the gasket I made instead of the metal shims . Side by side comparison the gasket is a little thicker . Don't have a mike . I'm turning the pinion shaft with pliers . Much tighter than it was before , also old setup had endplay . None now . I did whack the splined end with a heavy rawhide mallet several times . Thanks for your help , I appreciate it .

End play is all that counts... If you dont have any end play and its not TIGHT, then you got it !!

Whacked the pinion shaft splined end again this morn and now it turns a lot easier . Can turn it with just my hand . Still no end play . Plan to put the metal shims back in like Dr Allis suggested and see where I'm at . THANKS !!

If you can't turn it pretty easily by hand it's too tight and can potentially fail. You will have difficulty detecting any endplay. There is endplay if when the axle is in the working position (horizontal) you can move the splined end of the shaft any amount up and down. A little bit is fine.

Back out in my shop today . Installed the pinion shaft cover with the 3 metal shims dry . Torqued the 4 nuts to 5 lbs and it's a little harder to turn with my bare hand . I'm not sure if I should use a thin coat of RTV or make 4 thin paper gaskets ? Thanks for your help . Also checked the up and down endplay and it has very little .

You are obviously close, but if you torqued those bolts to 30 ft lbs it would be too tight. If it was mine, I'd clean every surface of all shims and smear some RTV on every surface involved ( 3 shims, 6 surfaces plus the cover and the final hsg toal of 8 surfaces). Assemble and torque to 5 ft lbs and leave it for at least overnite and a full day is better. I'll bet when cured you can torque up the bolts to spec and it will turn by hand easily. You do whatever you want.

Finally have my pinion shaft bearing pre-load set . RTV didn't work out , still hard to turn . Have to admit I didn't coat all 8 sides . Used the gasket I made and 2 paper gaskets I also made . Had 3 paper gaskets in . Took one out and I could feel a tiny bit more resistance . Figured that was good . Torqued 4 nuts to 24 lbs . THANKS Dr Allis , Steve , Tracy and anyone else I forgot . Moving on to the bull gear now .
