KAMA TS254 Reverse problem

[greg_g]

The problem might very well be as you described Chip. And if I'm all wet, I won't be offended if you tell Jeff to ignore my suggestion. But I recommended to Jeff that he split it between the mid-connect housing and the tranny. That will initially avoid some of the additional dismantling associated with splitting one box forward. With the shuttle box isolated from the tranny, perhaps a little rotational troubleshooting can further isolate which box the problem's in. If it turns out to be in the tranny, he's saved some dismantling and reassembly work.

Since the mid-connect housing internals are not accessible through the bellhousing anyway, why take it off the engine? I understand it's necessary for shaft removal, but why to check for/relocate a misplaced circlip? Breaking between the mid-connect and tranny will expose the aft end, removing the shift plate will expose the top, removing the transfer case expose the bottom.

But I don't know where "snap ring 6" is located in relation to any of those three openings.

Thanks Greg and Chip. Chip, how about Greg's idea? As always, I'm in over my head, but have no choice other than NOT fix the problem.

I was able to determine the snap ring #6 as Chip described, is the offending item. This was accomplished simply by removing the shuttle shift cover. Any idea the internal diameter of the snap ring? If I work at it, I may even be able to slip that sucker on without dismembering the thing?? Wish me luck.

Thanks

Looks like 25mm

If you can, you are better than my guys (its pretty far down there) but definately worth a try! is the bearing still intact under that gear? if so it will be fixed if you replace the snap ring. On the one we had, the missing snap ring allowed the bearing to slip out (caged needle bearing) and the gear and shaft were ruined, necessitating the total dissassembly. (I think that shaft does come out fht bellhousing side if I remember correctly. We benched the complete housing, but that does not mean it is necessary. My experience is that short cuts usually end up in back tracking and going the original route anyway, but others have better luck. Wishing you the best of it (luck)! I can measure the shaft on monday to determine snap ring size.

I must be living right. I was able to slide the roller bearing into the idler gear and push the snap ring back in place and all is working correctly. I used two long screw drivers to guide everything into place.Total time for the job was about 30 minutes!!! Replaced the shuttle shift cover, and away she went.

Thanks for all your help!

Man, that's great that you fixed it without tearing everything apart.

Yeah, I agree that is great you saved all that work. You are living right to have that happen.

Yep! Thanks again Chip. After reading your post a few times I realized I was in the wrong spot originally.
