NP 231 Seal tips

after rebuilding my TC both front and rear output seals are leaking. The rear seal that was installed by terraflex is leaking, and the front seal installed by me is leaking a lot. Got two new seals to put in. Any tips so I dont end up with more leaky seals.

They both leaked as soon as I took it for a test drive...

Make sure the yokes don't have a groove worn in them from the old seals, be careful not to knick the new seals, and smear a good generous dab of general purpose grease on the lip of the new seals to lube them up before inserting the yokes during reassembly.

There is a very fine grade of scotch-brite that is used by mechanics (also painters, I got it at home depot) which does a very nice job of cleaning up sealing surfaces.

I use a dab or rtv which usually helps. Don't want to do it a second or third time.

Yes, the suggestion of using RTV behind the seals is a good idea. If you watch the Advance Adapters SYE install video on YouTube, they use RTV on both output shafts.

This jack wagon didn't read the instructions for terafelx completely. They state in the instructions to use silicon on the splines when putting the rear output yoke on.... Im starting to think my seal wasn't bad, just me being in a hurry and skipping that step in the instructions..

Used RTV on the rear yoke, used a little grease and trans fluid on the seal and yokes when sliding them in and no leaks!


Now if I could only get my clutch/trans working right
