View Full Version : H42 with vacuum or split t/c???

The new '86 2F came with a 4-speed tranny and split case t/c. I was originally planning on putting a H42 4-speed in a using my orginal vacuum t/c, however, it appears that the front input bearing is shot on the tranny I have. Here's my options:

1. Rebuild the H42 and use the vacuum t/c or
2. Use the 4-speed that came with the 2F and it's split case.

I'm not sure which is better but I'm looking to do things once, and the right way. I believe that there is a different spline count on each of the tranny's, otherwise I'd just switch them out-- I haven't confirmed this yet. Please offer up your opinions on which route I should go. Thanks in advance.

use the split case. it's way better in terms of being stout than the brittle 64 case.

the whole shebang outta the 60

I agree! The tiny bit of lower ratio you get with the J3 case (from a 3 speed setup) is not worth the strength and better quality of the split case!

Just realized that there is no parking brake assembly on the split case. Is there a remedy?

I just swapped axles to 1976. The Man-A-Fre conversion kit listed above is no longer available. It's looking like I'll have to fab something from scratch or do a rear disc conversion. To be honest I'd rather put my $$$ towards something else then rear discs. Any ideas? I was kind of thinking about using the hardware off of 60 axles. Anybody have any experience with this?

Is there anybody out there that knows of someone that can rebuild a H42 or a shop that does decent work? I'm thinking about just getting the H42 working with the vacuum t/c and dealing with the split case later. Summer is coming really quick!!!

Anybody see an issue with using a remote m/c to activate just the rear drums? Here's a link on Mudd, post #16 http://forum.ih8mud.com/40-55-series-tech/417529-parking-disc-brake-brake-caliper-choice.html. Also found this on a blasphemous site: http://www.cj-8.com/forum/showthread.php?t=19916&highlight=parking+brake. Looks like those guys are pretty happy with it and for $50 + a bracket I'm entertaining the thought.

You can install an electric or manual line lock that does essentially the same thing for a lot less work. The problem with a line lock or anything else like this m/c setup: they can bleed off pressure and let the brake release.

Seems like maybe you should be able to use 60 or late model 40 rear drum plates that have the bellcranks. Then you could just use the cable actuated parking brake set up. (?)

The other problem with a line lock type setup is that the constant pressure in the lines will eventually lead to leaks--especially when it's super cold.

I've got one of the split case "kits" from SOR like the MAF one that is no longer available that I plan on installing in the next two days. I know that they aren't available any more (I've got to deal with this on my 45 still), but used I think they are still occasionally found from HJ-47s.
