Well the title says it all. My questions stem from the fact that I'm sure this is coming down the pike, a transfer case deal probably to follow, I don't know if the gears are rough or it's the bearings. I have access to a press which would help. any advice from those who have done it? best places for parts, gears, bearings and overhual kits. who should I stay away from? Thanks Ken

It's not too bad except taking off the input bearing and the output bearing, I went to the local tranny shop and used their pullers, no charge, get a good FSM and follow the procedure especially with respect to preload and clearances, be careful with the input seal, easy to screw up, if you have a press for the others you should be fine.

Disassembly is the hard part. Some of the bearings are really on there and defeat the special pullers.

Rebuilding them is uneconomical, since good used 4 speeds are pretty cheap. If the output shaft splines are worn or if the 1-2 syncho is bad, it is trash. Get another one.

Why do you say it's trash if the 1-2 synchro is bad? Just wondering. I am thinking about rebuilding my 4 speed when I go orion.

The only problem with buying a used 4 speed is that you don't know what you have until you run it. A lot of 4 speeds pop out of 1st gear engine braking down hills, in my experience.

Pin head, you have given me the answer I've been looking for. I'd rather go with a used one, than rebuilding. Next question. HOW DO YOU KNOW it's worth a spit, aside for pars rolling out of it. is there a method of checking the gear lash? can you see the synchro's from the top cover?

[Pin_Head]

The 1-2 synchro is very expensive, so it is cost prohibitive. Same for the output shaft.
Gear lash is not an issue. Wear specs are listed in the FSM.
Consider an H41.

Do you happen to know how much it costs? I'm thinking this is the piece I will need to fix the popping out of 1st issue I have.

[Pin_Head]

Last time I checked several years ago the synchro assembly was $600 and the shaft was $350 with my TLCA discount.

Just a quick comment. I recently rebuilt the H41 I have. It was rumbling really loudly in neutral, so I kinda figured the input bearing or the 17 rollers were toast. The bearing kit was identical to the H42 16 spline output trans. The outputshaft bearing was a beast, but I used a dremel to cut the outercage, then the balls just fell out, and off she came. A very thorough cleaning of all the internals in a parts washer made sure none of the grit found its way into the box. Had the case hot tanked at a shop. It really wasn't too tough, but that is one heavy trans! Have a helper to install it! Used Poser's two t-case stud method to guide the Orion onto the trans. SWEET! I spent about $275 to do this, so it was worth it IMNSHO.... For an H42, I agree with Pinhead...junk it!
Here are a couple pix for inspiration..camera phone, so not great quality..

Cheers!

Ok, now I'm know about the h55 5speed (too much bling 4 me) and I'm guessing I have an H41?... What did the H42 come in? A later model 40 or 60? what about the spline count? will it match up with my 78 transfer?
Anybody have one near VA/MD/PA?

I'm not quite in your geographical range ... but almost (about 50 mi. S of Danville, VA). I have an H42 that came out of my 4/76 FJ40 that will mate up fine with your transfer case. It has some visible wear on the output splines (pics available) but is otherwise in very good shape. Shifts smoothly in all gears, no grinding, whining, clunking, or popping out of gear. $50.00. PM me if you're interested.

BTW, the H41 differs from the H42 only in that it has a 4.9:1 1st gear (vs. 3.5 in the H42) - thus its desirability - and was not available on USA models, so those available are imports from other markets. HTH,
Alfred

Hey 1Fine40,

I have 2 questions for you. First, the H42 in my 87FJ60 is making a sound very simmilar to what you describe in your post. Which bearing ended up being the culprit?

Second, Do you have any close up pics of just the input shaft? If so, would you please post it?

Thanks.

Hey, will do me a favor and post up in my thread on what you think.. I got sold a Junk h41

I got sold an H41 that grinds really loud while in neutral, is the problem just the roller bearings?

I really don't know which it was, they both appeared worn. Best to replace both bearings on the input side...

Sorry, didn't take a shot of that, try this web site: http://users.starpower.net/johnsmith..._install_.html

Thanks.

Hope that helps some...
