I have a badly leaking pinion seal on a 741. Just take the nut off, remove yoke, replace seal and replace yoke/nut? No crush sleeve so no PITA, right?

Also, how do I get the yolk off after the nut is removed?

Just a lite tap with a small hammer on each side.

I've had some yokes that needed a slide hammer or threaded puller to get off....most don't.

No crush sleeve in a 741.

Is there a large flat washer under the nut, wasn't on mine & after torquing it (741 by feel a good amt) it's bound up & was good up until that point. Any thoughts JK
