    Upgrade yoke on d60 from 1310 to 1350, now not spinning freely?

    I bumped up my front d60 yoke today to match up with the rest which are all 1350. As i understood it, its just a matter pulling the old one off, slap the new one on (no preload, etc.... )

    There 2 shims on each the inside and outside of the yoke so those i reused. Replaced the seal, through some gasket seal on the splines and used a new yoke bolt. Calls for 250-270 ft/lb. before i reached 250 i checked it out and the yoke did not freely spin as it did with the old one???

    Any ideas why.?

    Check for a missing shim somewhere? I'm wondering if there is a chance you removed the pinion bearing for some reason and a shim got misplaced by accident?

    When you say difference in yoke thickness, are you talking about the "Neck length (i.e. from the face that is facing in towards the ring to the opposite face that faces the tightened nut)?

    I also noticed that i did not get a new slinger with my 1350 yoke.... That could possibly have played a part?

    Pinion Bearing preload for a D60 is 17-30 inch pounds for new or 8-10 Inch pounds used. If you torqued it to 250-270 ft/lbs then you likely damaged the bearing as well.

    Overall, pinion nut torque should have Very little effect on pinion bearing preload. Actual bearing damage would require a shim stack to be way too thin.

    Yes...though, it shouldn't really have a significant effect on preload since it does not effect the shim stack thickness requirement. I edited m first post because I was wrong - I was not making much sense when I suggested the difference in yoke length should matter - it does not.

    Only if a slinger is sandwiched in with the shim stack. Then it's thickness is counted as part of the shim stack. But there shouldn't be a slinger in with the stack to the best of my knowledge. I have never seen one in that location on a 60 that I can recall.
