Transfer teardown (literally)
So, it’s easy enough to show success and exciting sh*t here on the board. But I figure that in addition to leveraging others’ knowledge and experience it can be a resource to share mistakes so that others don’t make the same.
First of all my F-up could have been avoided by reading
just a little more here before hitting a snag. I
have the FSM and had reviewed a number of T/C teardown/rebuild threads. But each of those had (seemingly) gone smoothly and according to plan. Mine’s not SO bad but worth noting for others to learn from.
I was gentle with the soft aluminum when separating the rear case; used a plastic mallet and only hit the little ears and it all seemed to be moving slowly but surely apart with no prying.
My first hint of a problem was that never-good ‘tink’ sound of metal on metal when I wasn’t expecting it. Turns out it was the thrust washer on the front-case side as the idler shaft came off WITH the rear case. This is apparently not uncommon, but I wasn’t expecting it.
So I got the rear case off, but that M-F’n idler shaft was stuck!!
I graduated from the plastic mallet to the ball peen to the three-pounder. Of course it came out eventually but not before I had smacked the hell out of the case all around the shaft as I whaled away (getting more and more frustrated every swing)! :whoops:
Also, it’s obvious
NOW I should have used a drift (or an impact socket, or a press, OR ANYTHING!!!) to pop this out so as not to bung up the case. But I didn’t, so then I was faced with a scarred up case and wondering if the shaft would go back in given all the divots around the sides of the hole.
I spent some time reversing the procedure. Lots more pounding (this time with various items between the hammer and the case

) and cursing. The case went back on, but it wasn’t pretty; little slivers of aluminum came off where I had fouled the case as the shaft went in, and the idler gears were tight, tight, tight by the time I’d pounded, pried, pushed and used the bolts to pull it back together. (*possible explanation below)
It came back off too – a little more correctly this time; I’d back the rear case out, tap the idler shaft back in, case out, shaft in, etc ‘til I was back apart – so I am hoping I’ve crested the hill.
*I noticed this time that somewhere along the way I had bent up the ‘oil reciever’. Probably caught it on the trans-input shaft one of the times it was all coming in and out. I think (hope) that this is what caused the idler gear to not turn easily when I was re/test fitting the case back together.
So here I am. I’ll progress with the rebuild and attachment to the new tranny, but I won’t REALLY know if there are any serious problems for a while as this is just one small part of a large project and there won’t be even close to a drive train to hook all this to for months and months. I WILL show off the new H55F as I move this t-case on to it over the next few weeks (not this weekend – SocialD in Salt Lake and then mother’s day so I don’t see too much wrenching...) and will try to continue to document.
Sorry for the novel of a post. I Hope this helps someone someday. It helps me to “vent” about my stupidity.
