Have you looked into a different engine mount that allows you to slide an adjust the engine back & fourth ,
rather than side to side?

My problem is i Can’t fit the stock clutch bell,the shaft seems short, I can’t secure the bell in place using the screw, if I will tighten it the bell will also lock it won’t turn, thanks for the quick response.

Yea ,but I also thought that you had an alignment issue as well with the spur gear!

You might need a different flywheel as well ,some are thicker than others!

Ok thanks, I will look on to other flywheel..I hope someone who have the same set up will chime in to help me find the right flywheel, again thanks..

Gwt the ofna shim kit. It comes with 2 sizes of flanged bushings that fit in the bell sort of extending the crank.

 

[sv250]

Found 2 other options available at amain

 

[sv250]

The part number didnt show on the 2nd one. Ptk-7150

Did that truck use to have a gas engine in it?

 

[rdk09]

It’s lst2 that I convert to xxl2 chassis..

 

[rdk09]

Here she is..

Beautiful truck!...

The reason I asked ,is because ,Losi put out a gas version ,an it has a different much thicker flywheel!
I assume that it is the 2 spd. clutch bell with the two gears on it!

The only thing you can do ,is to try to find a thinner flywheel an thinner clutch shoes!

I seen sv250 showed some options ,I've never seen those types of parts before ,I'm glad he showed them
in case that I might need them!.....

Usually ,most big block crank shafts are the same length ,I would try a small bushing about the same diameter
as the crank shaft with a longer screw ,maybe cut the tip off an old crank shaft to the length you need to use
as an extender bushing!..

 

[rdk09]

Thanks, the first part that sv250 showed has already in my shopping cart, yes me too it’s my first time to see that this part exist lol, this slowing down my build, I’m stuck with this problem.

Just an update the serpent thrust bearing spacer will not work either, problem with alignment between spur and and the bell, the nitro forum is really dying, I can’t get any more answers from different rc online forum, the very sad truth lol..

We all been involved in RC;s for many years ,but all of us didn't build or modify every RC on the market!....
