Thread: Intermediate Shaft Thrust Washer

I know this doesn't answer your question but I am hoping you might be able to help.

Does a worn thrust bearing cause a vibration and loud noise from the gearbox when using engine braking?

I would check for a loose nut, part no. 217477 at the end of the main shaft first. .W.

I doubt it - many years ago I had a thrust washer break in two and fall out (the result of being assembled (not by me) with too much preload). This was symptomless until part of the washer went through the gears and marked them, so we had a 'tic' every revolution.

The end thrust on the intermediate gear from the spiral gears is almost identical but in opposite directions from the input gear and the output gear as the same load is being applied in to both. This means the only reason for having a thrust washer and shims to adjust the clearance is to prevent a click if the load is taken up suddenly.

Thanks for the tip, is that nut reachable without pulling out the gearbox or overdrive? Also do you know of any hacks to tighten the nut without special tool 600300.

It's not possible to get to that nut with an overdrive fitted. Without an overdrive you can check for looseness by removing the cover plate for the PTO selector. To tighten the nut you have to remove the back bearing housing. . It's best to use the proper tool, or a home made tool that serves the purpose. If you use a steel drift you damage the nut, if you use a brass drift you chip the brass that will end up in the transfer case. .W.

If there is an overdrive - no. It is inside the output quill drive of the overdrive. If you don't have an overdrive, you can see it, and probably determine whether it is loose by removing the small cover on top of the transfer case.

I made a special tool out of a piece of water pipe using an angle grinder to shape the fingers.
