Oil around front pulley cover

[NCB]

OK, was checking the front pulley nut and appears there is some leaking of oil on the inside of the front pulley cover. Anybody know what I should order to get this fixed? Thanks

I took the cover off of the front pulley and the oil that is leaking does not smell like gear oil. I sure that it is motor oil. Where could motor oil leak from and end up on the inside of the front pulley cover?

I believe that is motor oil behind the seal, behind the pulley. Gear oil is on the other side of the bike. Id replace the shaft seal and o-ring behind the pulley and you should be good

Behind the pulley is all transfer case components lubed by gear oil.

Yea, I know that. It just does not have that nasty smell like gear oil. Maybe the smell goes away after being installed for a while. After taking a closer look the oil could only be coming from behind the pulley. I ordered the o-ring and new oil seal. Also ordered the older style nut and lock washer. I'm assuming that is all I will need. No reason to think that the bearing has gone bad?

Is there a certain process for installing the oil seal that sits in front of the bearing? I have planned on replacing the o-ring and oil seal and a new nut and lock washer. What is the correct torque for the pulley nut? Thanks

[NCB]

Hope do you install the oil seal? How do you know that you have it far enough back?

Check to make sure it's flush with the case. It should have a lip behind the seal, but I'm not 100% sure.

I was told that tightening up the pulley nut could solve my similar problem and it did. I had already ordered the new seal, oring and new lock washer, but since my problem is fixed at least for now I am just keeping the parts until I need them.
