SO i ordered all the parts for the rebuild.
All the parts and the master rebuild kit.
On older NP231 the drive sprocket has needle bearings in side drive them out they will not need to be replaced with SYE (at least for this kit)
Now I took the front half of the case and used a seal puller to pull the seal.
I used a punch to drive the bearing out. Sorry no pic but later picks show me doing the same thing. Then i drove the new bearing in with a socket just smaller than the bearing. Yes a bearing driver would be better but trying to some some alternatives for people limited on tools.
I used a 4x4 block of oak to drive the new seal in.
Then take the four bolts that hold the plate that holds the bearing and seal of the input shaft.
Remove the snap ring and tap out input shaft. drive the bearing out of the case and the seal out of the retaining ring.
Drive new bearing and seal in place. Be sure to scrape all the silicone from both parts and clean throughly. I use alcohol But paint thiner works as well at end to ensure there is no oils so I get a good seal.
To remove the bearing in the planetary use a long punch and remove.
To reinstall the new bearing Used the used output shaft (sorry no pic). now reinstall planetary and input shaft replace the snap ring. clean the area to be silicon-ed with alcohol or paint thiner. put a thin coat of black RV silicone and and bolt to together. Do not put to much silicone on do not want it in the bearing.
Now you can replace the front shifting fork Assembly.
Now install the gear assembly you removed from the rear output shaft to the new one. Forgot the pick but should look like the one that came out except shorter lol.don't forget to replace the snap ring. Now install it in to the case. carefully aliening everything as you go. Do not fore any thing.
At this point in stall the rear shifting fork and shifting ring. This takes a little work to line everything up as you go. Turn the shaft or ring to help line up splines. don't forget the spring.
Now put the new chain and front output shaft back in gently tapping the shaft into place.
Now put the magnet back in place. check the o ring int the oil pump.( I replaced the oil pump for simple fact i just drooped $550 in rebuilding and $40 pump was cheap insurance. ) replace anything that looks like it needs it. Place black RV silicone on one half the case.
When i put the two half's together i put the oil pick tube and pump in place and held them in place i lined everything up. Needed three hands just for that so did not get any picks. It is very in important to make sure oil pick up stays in groves and hooked to pump as you complete this step. After you get them to together examine oil pump and pick up tube and make sure they are still connected and in prober place. tok to specs and turn shafts on case make sure they turn well.
Now clean and silicone the new SYE casting and install with OE blots.
Now all you need to do is install the U joint yokes and install in your jeep.
Hope this helped you out a little.
And please forgive the spelling that is my weak point.
