Np241 stupid bearing removal ?

[scouthead]

getting ready to bolt the np241 back on to the K5... decide to replace input seal so ATF will stop getting into the tranny (SM465)...

plastic ball bearing cage on the input bearing is broken.

I know the input Shaft itself has to be removed from the rear of the case (split case and watch the needle bearings fly!), But I was hoping to be able to just pull the bearing itself out the case front. Any chance of this happening? Or should I just start scrubbing the dirt off the case now and find somewhere to spill it's guts?

Also, while looking around last night, I found 2 different part numbers for the input bearing on an NP241. How do I find out which one I have? Case is out of an '89-'90 Suburban 2500 (32 spline input).

I'll go snap a pic, and check back in a while...

Have a look through this product review. Plenty of pic's showing the tear down and re-assembly of an NP241

tRusty, I couldn't do the input swap on my tcase like we were talking about before..........casue the one in the chevy is a borgwarner I didn't know that until recently. no matter I'll just use the whole 241 as is.


btw, wheres the build up thread for your bigugly? I'd like to see that truck as it changes.

Been snapping a couple of pic's here and there...but don't want to start a 'build' thread until I'm further along.

I'm close to removing the cab from the frame now.

I forgot GM used the BW cases on some of their trucks. I know Ford used a lot of BW cases...

Well, yes... but not really. I have read that write-up and a couple other similar to it, but the input, the gearset, and the entire front half of the case is barely even mentioned. The article is focused only on the bare minimum of work required to install the SLE kit.

Answered this myself the hard way.

Had a go at just prying the input bearing out of the case with it fully assembled, but couldn't get it to budge. Opted to crack it open rather then break something.

It WOULD have been possible to pull the bearing only, but it is lightly pressed into place, and would pull out with the help of a slide hammer or some kind of puller. It tapped back in easy enough with a brass drift.
