H55 help needed. (1 Viewer)

Well I gone and dunnit now. Pulling the 5th gear off the output shaft I managed to chip some teeth. Is it salvageable? Can it but filed down or should I just replace it?

Anyways, that's the least of my problems: Measuring the thrust clearance between what i believe to be the 1 and 2 gears, I got 0.022, which is way over spec. Does it matter that i had the trans dissasembled as in the pic? would that change the thrust clearance?

The # 3 gear was at the hich end of the spec, but within limit.

So then i noticed wear on the (what i think is) 5th gear, (the very front one on the input shaft). Previous owner mentionned that he was hearing a noise in 5th gear, that's why he retired the transmission. It is out of an 83 bj60.

I need advice from people wiser than me!!


The chipped 5th gear, on the rear of the trans output shaft:



The state of disasembly when i measured the thrust clearances:




What i believe to be the #1 and 2 thrust clearance measurement:





What i believe to be the #3 thrust measurement:



The wear on the very front gear of the trans case, it's over several teeth:




Thanks for your help!!!

1. I would file the damaged teeth and put it back together.

2. You definitely have to have the transfer case housing and gears torqued to the back of the trans to check those clearances. I once had a customer return an H41 that a transmission shop told him was out of spec. It turned out that the output shaft had moved slightly forwards as opposed to the output bearing, and only torquing down the t-case would have pulled the shaft back up snug against the bearing.

3. The wear on the input shaft does look worrisome. How much does the shaft wiggle?

The shaft has a fair wiggle to it, I know that the bearing is gone on the input. The coutershaft gear looks ok.

The previous owner states that he stopped as soon as it sounded weird, and towed it home. He is a Mud member as well. The oil was clean (except for some sludge, but no metal bits). The wear on that front gear looks to be uniform, towards the rear of the gear, on every tooth.

So it's "acceptable" to file the chips down? Seems like there is still a lot of good contact area judging by where it is shiny.

Thanks!
