MG MGB Technical - 3 synchro gearbox rebuild

I am on the job to rebuild a MGB 3 synchro overdrive gearbox. On the main shaft, I measure an excessive side play of 0.20 … 0.25 mm where it should be 0,10 … 0,15 mm. I can't source a thicker thrust washer (MOSS 11G3129) to reduce this play. Instead, I am thinking about adding a 0.10 mm washer on the back of the first thrust washer (MOSS 1G3492) to reduce the play of the assembly. What do you think about this solution ?

Thank's for your advices.

Pierre,

A very technical question. Can I suggest you ask Chris Betson. You can find his fourm at http://octarine.mywowbb.com/
You may need to register to post (which is free), but Chris is an engine/gearbox builder and will probably be able to help you.

Cheers
