It is in my end play for sure my problem:

#7 - Setting the endplay is the next step. Remove the thrust assembly and clutch bell (be careful to keep the shims together for the gap). Install the bearing that goes into the backside of the clutch bell and slide it onto the crankshaft. When you do this your clutch bell should not drag on the clutch shoe. If it does then you need to add shims before sliding on the inner clutch bell bearing and clutch bell.

>> My clutch drags on the shoe. Where do I add the shims ? Between the first bearing and clutch inner bearing ??????

Thanks

if your clutch is dragging, then you should be adding shims between the spring adjustment and the first bearing.

Thanks Baedarlboo. I kind of thought it would be at that location. Just felt that the support of the shims was flimsy when retaining on the spring ajustment nut.

Am I the only one that thinks it's strange that mugen wouldn't include those shims with the kit? They don't even tell you to shim there. I learned to do that a few years ago but I just can't understand why Mugen doesn't want you to get rid of the endbell dragging on the shoe.

It's odd that MTX-4 manual does not mention a single word about setting end play and of course the car also doesn't come with shims for that.
When you are shimming the end play, make sure that the outermost shim (closest to the 2 bearings) has a small outer diameter (max 8mm), otherwise it will rub on the bearing. It takes a lot of shims to get rid of the end play on Mugen clutch, a bit over 2mm is what I have usually ended up with.

Umm, they won't be resting on the adjustment nut, unless you run zero or negative spring preload, which we never do.

It does suck that the car does not come with enough shims. I had to dig, dig and dig some more to barely come up with enough (right size) shims to make the clutch work perfect.

That's excellent advice ! "make sure that the outermost shim (closest to the 2 bearings) has a small outer diameter (max 8mm), otherwise it will rub on the bearing."

Can I use (max 8mm) shims for all the shimming ? 2mm of shimming is a lot of shimming. Is there anything else I can use ? What do you recommend as shims ?

people have reported using one side of the thrust bearing as a shim...i don't have an extra thrust bearing, so I personally have not tried it, but it's been done.

Default Collet used ???

I may be using the wrong collet size.

Anyone out there have a Mugen part number for the proper collet or any other manufacturer that works ?

I don't know if this work in your engine ..... I'm using another 5x8 bearing as shims substitute ( so total three 5x8 bearings before the clutchbell ).

Tamiya, Xray and Serpent sell the shims you are looking : 5x8x0.3
