So I was *really* hoping to finish assembling my gearbox before my trip to the UK, but perhaps it is not meant to be...

 

In the midst of rebuilding the gearbox I checked the endfloat of the laygear and i could just about fit a 0.015" feeler blade into the gap between the laygear and the smaller thrust washer. That is HUGE. Keep in mind this is the original thrust washer I had when i took the gearbox apart.

 

Using a vernier caliper, I measured the thickness of the smaller thrust washer to be in the 0.124-0.126" range. To get the endfloat down to 0.003 I'd need a 0.138" thrust washer, but the thickest sold on minispares is 0.132"

 

is there a source of a thicker thrust washer? If I were to fit the 0.132 washer the endfloat would be exactly 0.006 provided the washer wasn't thinner than it was supposed to be.

 

Is it possible to get a thicker thrust washer? Also seeing as the endfloat must have been so out for so long, what damage would that have done?

First of all check the thickness of the larger thrust washer at the other end of the layshaft.  I can't find what the thickness of this one should be but someone will be able to tell you either on here or phone Minispares.  If that is worn then a new one will reduce the gap.

 

If it is the correct thickness then shims are available to put behind the thrust washer.  See here:  http://www.theminifo...t-washer-shims/

hmmm would those shims have the same problems as the old type thrust washers without the tabs?
