    Looking for planetary gear shim part no. 142166

    Went to the usual places but this one seems to be unavailable. For those of you who have worked on your diffs, where do you go?

    I used this marvellous tool on my computer called google. It found a number of suppliers who suggest that the part has been superseded.

    Here is the replacement part from rimmer bros, who I believe have the set up to ship to USA despite the best efforts of POTUS

      I think that’s a 0.56 Richard, he needs a 0.54. Some sizes are available over here, eg moss or TRF but the 54 is not coming up.

      When I did mine I tried the next size up but it would not fit so it’s pretty tight. But maybe a 56 would work if there is some wear in the sungear shims?

      Thinking out loud perhaps you could make the sungear shims a few thou thinner by wet sanding them on a sheet of glass? You would have to make sure they are exactly the same thickness though..

        it would appear to be 0.055 - 0.056 55thou - 57thou.

        There is also a 51thou-53thou here https://rimmerbros.com/Item--i-139951

        When I rebuild them I have a few shim sizes either side of my measurement and get it as close as is possible. Not entirely sure that zero backlash is a great idea when the shims are not made from the OE materials anyway and 1thou would be pretty good.

          It’s certainly worth trying a 0.56.
          I actually found Sujit a couple of 0.54, my mate in the British car business has two on his shelf.. he can also get him a pair of 0.56 and brass sunwheel shims as well.

            I'm with Ricahrd on this. When I measured the old shims I couldn't match them to any of the known sizes across their whole surface. Ergo: they wear with use. So even if you get to within one thou accuracy on assembly I reckon that's going to be 5 thou out after a few hundred miles and the diff will still be working fine.

            I got as near as I could and the choice wasn't hard - it was either a shim which I'd have to lever in, or the next size which just nicely slid in. I took the latter.

              I just pulled out the shims of another diff and the no. stamped on them were 56. While I wait for my shims, I got my son to 3D print his little thing. It basically holds two ball bearings in a cradle so I can measure a curved shim more accurately.
