clutch

you can actualy change the collet over from the 3.3 and use a shim it will fit then the picco collet is too long

I'll have the hit up the LHS today and see if that works since this isn't a engine swap. What do I have to shim, and how? Sorry, newb and first time aftermarket engine install.

you can buy the collet for the traxxas engine and it will come with a shim if not they sell the shim the collet is part number 3281

Where do I shim and what size shims should I use? Here is a picture of the picco with the old flywheel so you can see the gap between the flywheel and threads on the shaft.

With the correct beveled cone/collet you would most likely not need a shim.

Split beveled cone.


I don’t see a cone in the pic??? If you have to use a shim it/they go between the cone and the front engine bearing.

the shim will go behind the collet but i do at the front of the bearing i dont think the picco collet will work i used the traxxas one

I'm going to head over to the LHS ( I feel wierd doing so since I didn't buy the engine from them since $174 from tower was unbeatable)

Here is a pictrue of the picco with collet. BTW I put the carb on there was a rubber tube in the bag that I'm not sure what it's for. Can someone identify what its for?



Can I turn the fuel inlet to the other side or do I have to route the fuel line to the other side?

i dont know about that rubber thing ....but you should be able to turn the fuel inlet the way you want it to be

Yup, loosen the top, turn the base. Tighten top.

I went to my LHS and was reminded why I don't shop there too often. The guys a total a$$. He told me my picco had the smallest shaft he'd ever seen, all the cones are the same, and if I wanted to shim it I should go to a hardware store and buy some metal washers. I didn't get anywhere with that venture.

lol...what a moron ( the LHS guy ..not you ..lol )...all my engines have the same size shaft as my 3.3 ..including my picco .26 and wasp .28 ...lol...and i know there are longer cones ...the one i got with my 3 shoe clutch was to long and i had to file it down to the right size
