Post by: drtbikkid on May 03, 2012, 10:19:52 am

how involved in replacing the rear seal (output shaft) in an NP205? im afraid when i get the housing off a whole mess of stuff might fall out that im not expecting.

any help is appreciated.

What housing?
Remove the drive shaft, then the yoke, pop the seal out.
Use a deep socket or nicely install the new one with a brass punch, put the cleaned up yoke back on with a some blue locktight, stake the nut with a small chisel, put the shaft back in.

You shouldn't need any silicone for a seal.
When you do use silicone it should be the good stuff, not the blue crap!
