Hi there,
 

I am currently rebuilding my engine.

I got new Bushings in the Primary gear and a new C-Clip and retaining Washer.

I got a  .120 thrust washer.

But i still got a Endfloat of 0,3mm which is about 12 thou ".

I am aiming for 5-6 thou.

 

Anyone got any Advice on how to fix it.

It is a Super Fast Road Engine and i really want to do it properly.

Measure the thickness of various tins,  or the alluminium seal above coffee cans that you have used in your kitchen.

 

Cut a circular washer and fit it between the crank and the primary gear spacer.

Have you got the old c washer and retaining washer? you can turn them around and that can give a couple of thou.

Have you tried that? wouldn't they spin and wear very fast and while doing that, ruin the face of the Crankshaft? 

But those are only thoughts... If it works i am more than happy to try it! :)  Maybe those spacers for the "Pulley side" could fit.

I already put a new C-Clip on there.

I see MiniSpares also have them at 122-124 thou, that should bring you down to 8. Also, have you measured your 120 thou thrust washer? Although I don't expect it, it could still be out of tolerance. I would also consider buying a set of imperial feelers so you know it really is an x-amount of thou rather than converting from mm.

Yep saw that, if you have the old one try fitting that in both ways as you may get a different result compared to the new c washer.

So today I went to a Mini Workshop near me and measured all of the thrust washers he had, the widest was .119 (3,04mm). 

The one i had was .118.

Additionally I found an old C-Clip which after putting the other way around gave me a little.

After measuring properly with a "Micrometer Clock" (sorry i don't know the vocabulary there).

I am now down to 8,6 thou. (0,22mm).

 

Which all in conclusion means that i will need to order one of the .122-.124 Thrust washers at minispares.

Which should get me where i need to be. 

I hope they will hurry up for once.

 

Thanks for the Help!

I got the new thrust-washer... Obviously it had to be a bit undersize :/

But i got it down to about 7 thou and put it all together.

Thanks for your help and advice
