Hey Uber, I have a 2door sedan with a 1.7L Djet 4speed with the flat pan gear box. I thought Ray said the Gear box was the part that explodes,lol! Wanted to have one to do the mods for the oil movement and replacement! I always thought the bell housing was just the clutch arm and bell? I just thought the two seperated but I havent played with the tranny except pulling the pan and cleaning and refilling. Thanks for checkin, Bill

Please do. I presume it is for sale since you mentioned it? And why is this car in a boneyard when it should be in my garage? :lol:

Yes..parts are swappable.....but great care must be excercised. As Dr. Uber has noted....the tranny is in two parts (actually three if you want to count the tail cone as seperate).

When you disassemble one, the entire transfer case sction with the counter shaft comes off of the tranny...leaving the entire main gear stack still intact on the extremely long pinion shaft.....sticking up out of the differential housing.

The location of the counter gear cluster to the main gear cluster...is set by a pair of shims between the ends of the counter gear cluster and the transfer case housing. Therefore....that means that the transfer case has a specific relationship...to the setting of the counter cluster...and therefore the main shaft gear cluster.

Now....one more thing. The main shaft gear cluster also partly governs where the counter cluster must meet up with it.
This is because...the pinion shaft bearings are set with a shim between the input shaft nose cone and the differential case...to get proper pinion mesh with the ring gear.

So.....if your main gear cluser craps out and you are left with a good differential section....you can swap a transfer case and main gear section to it.....But....since the pinion shaft is already properly located to teh diff section...it must be left there.
Before discarding the old destroyed main gears and counter cluster...you must look on the back of the counter cluster shims. The thickness is stamped there. The donor counter cluster gears with shims, the donor main shaft gears with shims, the donor transfer case housing and the donor snap ring behind the big ball bearing must all be used.

The is sometimes the possibility that the differential housing may have enough difference to make the main stack protrude into the transfer case differently...but that would be rare.

In short...the pinion shaft and diff stay together...and the transfer case and all else stay together.

If you are changing the diff and keeping the transfer case....you must leave pinion shaft with the transfer case and main gears.
From the donor tranny...you will need the diff and the diff case. But....the shim under the mainshaft nosecone (the five bolt part that goes through the TO bearing) as well as that nosecone...must come from the diff case that you are replacing. This will keep the mainshaft spacing correct. But you may have to press off the pinion gear and swap shims and possibly reset the pinion preload from the inner bearing with the adjuster ring.

Keep all parts of each tranny well seperate until you decide what you are doing.

This is important because there is very little adjustment that can be done...save for about four shims in the whole tranny. Ray
