NP231 Input Seal Question

I just got finished pulling my NP231 out of my YJ. Replacing the output seal on the AX15 is pretty straight forward, but I have a simple question about the input seal on the NP231. I assume I pull the whole retainer, correct? Then just plop a new seal in and be off, or will parts be falling out when I pull it? [img]images/graemlins/blush.gif[/img] Any idea on what to torque it down to, or just firmly tight? Thanks guys!

Re: NP231 Input Seal Question

You can remove the seal with out removing the retaner. be sure to lube the shaft and seal before installation. You can also remove the retaner. No parts will fall out! Clean all surfaces. Use silicon on the retaner to case surface.
Locate the oil return passage, don't block it with silicon,and install in the correct position. It will be easy! Good luck!

Re: NP231 Input Seal Question

I see this was your first post, so welcome to the board! Thanks for your help. How would I get the seal out without removing the retainer? If I pull the retainer, I assume the oil return passage is pretty obvious and easy to keep free of silicon?

Re: NP231 Input Seal Question

Ok, well, I just did the seal. I pulled the retainer, and did it that way. Lots of silicon there to clean up. I ended up taking off the larger snap ring/c-clip, but put it back in the same spot. As for re-sealing it, I just used some hi-temp black sealant and smeared it all over the piece, but making sure that the oil-passage was open. We'll see if this does the trick!! I didn't know what to torque the bolts to, so I just cranked 'em pretty good and blue-lock-tighted them. What ya think?

Re: NP231 Input Seal Question

hey jammy just a word of advice... i had the output seal on my AX-5 go, and the first time i replaced it it lasteed about 2 months then started leaking, ,so i replaced it again, and about 2 months later it started leaking...what happenedd was, that i wasn't putting the seal ALL THE WAY IN, when i installed it, just make sure its as far in as it can go, or it'll leak, when i put mine in i put it so it was flush with the rest of the housing if u wanna call it that, but it does go back a little bit further, if that made any sense just let me know...but yeah make sure that seals IN! HA
