Rear pinion seal (1 Viewer)

I only need to replace the actual oil seal right? I can reuse everything else?

Buy a new pinion nut as well.
The old one is staked to the pinion.

I'm a big fan of the Marlin HD pinion seals.

Well if the nut is needed then its time for a rebuild and locker for my 47 after reading the below thread.

Leaking Pinion Seal....here's why...

Ehhh... Although that's all correct, I've gotten by doing it "improperly".

You, me and 95% of the rest of the world.

Grab the pinion flange and see if there's any up/down movement. If not, just swap out the seal.
The 47 probably has a spacer between the bearings and you shouldn't have a care in the world.
The 80 might be a crush sleeve. Just don't torque the nut over 100 ft lbs​

80's are all crush sleeves
