What happens when you torque a pinion nut?

The marking of the nut on the pinion will put you very close to the org. torque if you are just changing the seal and not messing with the crush sleeve or shims.. It will put it back because the crush sleeve is already crushed to the point where pre load is, or should I say was set.

What’s the torque test on a Chevy yoke nut?

In other words, put the inch pound torque wrench on the pinion nut, with the carrier and ring gear OUT of the housing, and continuously spin the torque wrench and pinion, while reading the scale. If the drag is too low, tighten the pinion nut a small bit, and do the drag test again.

Is the set distance Shim a nut torque design?

The set distance shim design does use a nut torque, so, you need to get the drag AND nut torque correct on this design ONLY.

What happens if you torque the yoke nut on a crate 350?

Crate 350.Edelbrock intake,cam and carb. You DON’T torque the yoke nut. The pinion has a crush sleeve in it that – if you over-torque it, will crush excessively and accelerate the gear wear (and it will whine a lot and possibly self destruct if bad enough).

How is torque measured on a pinion nut?

There is no actual torque spec for the pinion nut. You tighten it until you get the correct amount of “drag” (actually called the pinion bearing preload) on the pinion bearing. This is measured in inch lbs with a dial type torque wrench.

What happens when you change the seal on a pinion nut?

Doesn’t matter weather you replace the seal or the yoke both require loosening the nut, so the procedure doesn’t change. The “mark the threads” procedure does change or become invalid if the new yoke has different dimensions which I think is the case with the OP.

Can you change the bearing preload on a pinion nut?

If the new yoke and old yoke are as little as .005 inch different in thickness then your pinion bearing preload will be way off. Torquing the nut will not change the bearing preload.
