Anyone thought about de-integrating the integrated t-case on an MUA and replacing it with something such as dual Toy cases? One option would be to strip the case, cut and respline the mainshaft further up toward the tranny, cut off the original front output area, and make a block-off plate to seal it all. The slip-yoke would then fit onto the newly-splined section, with a groove machined into the block-off plate to accomodate an OEM Isuzu slip yoke seal. OEM yoke welded to a plate machined to match up to a 'Yota divorced case (similar to how mlclark turned his slip-yoke rear output into a fixed-yoke). I have a few other options in mind; but just wanted to put this up for discussion.

interesting muse. But other than the fact of "doing it", wouldn't there be an easier way to obtain the same(ish) result? Or are you thinking an alternative method to dual cases?

I'm not sure its any harder than what a handful of us have done with stacking the auto on top of the manual isuzu cases... especially if you've already got a line up on the resplining work. plus the net result of having two toyota cases over two isuzu cases would yield more gearing options.

Moser is in Indiana. They custom spline/respline axles all the time; so I don't see them having an issue with this project. Not looking to do this anytime soon... more trying to spur a good discussion. One of the issues with dual Isuzu cases seems to be fluid capacity/cooling of the front case once the output is lopped off. Overall length of the dual Isuzu combo in a 1st gen Amigo leaves the rear driveshaft rather stubby as well <img src="/forums/images/graemlins/lol.gif" alt="" /> I don't know that this combo would be any shorter, though. Another good combo would be the 231's range box/D300 combo mated with the 'box for rocks' kit. What would be REALLY nice is if the Isuzu mainshaft was of a size that it could be machined/resplined to work directly as an input shaft for one of the above combos. <img src="/forums/images/graemlins/cyclops.gif" alt="" />

yes, thats definitely a problem based on my experience. If I had been trying to keep my rig on the street, a electric pump and externel cooler would have been requirements for me.



see, coming from the Rodeo side of things, this wouldn't be a plus in my book. I had plenty of rear shaft, but my front shaft was the one that could have benefitted from more length.



Yea, I dunno about the Toyota stuff, but just off the top of my head, I'm guessing not for the 231.


Another thing is this would give you the option of running a front CV joint if you so desire... which just isn't possible for me due to the tight clearance between things.

A few folks have worked successfully with the integrated t-case to stack up separate solutions... I spent a long time working on that, myself. In the end, I elected to chuck the MUA5 and it's integrated t-case, and start from scratch with another bellhousing. The MUA5 is a good tranny, but the integrated t-case had too many downsides for me.

Sean, let's touch base and talk about this some evening when I don't have to type so much... my carps are tunneling. :p

Search on "R151" with me as the author to get some free-reading on the subject. Here's a start:

Differential tendon glides, median nerve glide, extrinsic stretches, ASTYM, and edema control... possibly a forearm-based neutral wrist splint for night wear if you tend to 'curl' when you sleep or need it for work. Thanks, randii... I finally get "home" from work at 10:30 and you have me right back at it. <img src="/forums/images/graemlins/lol.gif" alt="" /> I'll give the links a good once-over hopefully soon and give you a call when life drops off a few notches. <img src="/forums/images/graemlins/cheers.gif" alt="" />

If the 4ZE1 to T5 bell worked for you, I wonder how viable the 4ZE1 to "auto used behind early Troopers" tranny is as a blank for the same purpose. I already have one of those laying around for another potential tranny swap down the road.

What does the backside of that bellhosuing look like? What you need is some sort of index by which you can center the transmission relative to the bell. The T5 housing has a large circular hole bored on center, which makes it easy... without that, you might need to indicate the bolt holes and claculate the center relative to a transmission housing (not impossible, but beyond my capabilities).

If you reduce the bellhousing down to its most simple function, it exists to hold the transmission body in parallel relative to the engine block, centered around the in-line axis of the transmission input shaft and the engine crankshaft. It also contains a clutch, fork, and some other stuff, but ignore those for the moment. <img src="/forums/images/graemlins/pfft.gif" alt="" /> You're essentially managing two bolt interfaces, which keep the engine and bellhousing aligned and the transmission and bellhousing inline. If you start with a bellhousing that bolts to the engine, you're halfway home... maybe more, since you the backside of the bellhousing is likely parallel to the front. The trick is figuring out tranny input shaft centerline and getting it inline with the crankshaft centerline ... this is a billion times easier if your bellhousing has a concentric circle (relative to the tranny input) available for reference.

Large circular hole... unsure of how centered it is; but it looks centered:



Being for an auto tranny, though, I don't believe there are any provisions for clutch/fork operation. All I have is the one picture... further investigation will require digging through the parts pile <img src="/forums/images/graemlins/scared.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />

The circular hole is the magic... installing clutch gear in there isn't that difficult... especially if you use a hydraulic throw-out bearing.

Cool --- I hadn't seen one of those before!
