Default Need help shimming my clutch/flywheel please.

First off, I am trying to prepare the Losi 4 shoe clutch that comes with the truggy race roller.

I have three questions:

1) There were two different shims provided (see picture). I know the small one goes behind the screw cap that screws into the crank shaft. Where does the big one go?

2) I am having trouble getting the bigger bearing into the back of the clutch bell. Any suggestions?

3) What is the optimal setting for shoes and springs on the Losi clutch running the werks B7 engine?

Thanks.

That is 3 question, not 2.

That one goes either behind the flywheel and collet to space the clutch bell out more, or is a rubber seal from the inner clutch bearing. hard to tell from pictures.

2. Put the bearing on the crankshaft and push the clutch bell on and see if that works. I have never had any problems with that, usually the inner clutch bell falls right out.

3. Try 2 blue aluminum/2 carbon with all 4 gold springs. The B7 doesnt have alot of bottom so try running harder springs. So 4 gold or 2 green/2 gold.

I have tried a few things including WD40, but that bugger still doesn't want to go in.

Ok - I will play around with it a little.

Thanks.

Interesting - your statement about being easy got me to try a different bearing (one I have from Answer RC) and it fit great. In fact I can't get it to stay because of the WD40 oil I put in there

The bearing that came with the roller from Horizon.

Sounds like the wrong bearing.

As for the B7 not having any bottom... depends what pipe you run. I had one with a JP-1 on it (yeah, maybe a mismatch) but it was like a light switch. Off or spinning tires.

Hey Domit,

Good to see you outside of the thread from hell

It's possible I used the wrong bearing, but highly unlikely since there were only two in the plastic bag and it had the rest of the clutch pieces in there too.

I have matched it up with a 2013 on recommendation from the Werks man himself.

If that bearing won't go in all the way, it's like maroon or blue right, put it in the best you can assemble the clutch. After you tighten down the screw take everything back off and see if that worked to slide it in the rest of the way.

Tried that, but think I damaged the bearing by tightening down too tight.

Thanks - Once the bearing went in - everything else just fell into place. The clutch /flywheel are on, the gears are meshed, the truggy is almost built and ready to go.

Yay.
