Losi / Fioroni clutch problem
Hi guys, I really am hoping someone can help me out here...
I have a Losi 8ight 2.0 B and am atempting to run a Fioroni turbo clutch system but am having a few problems, i have the OT FR 52 flywheel which after a race meeting or two however tight i do the flywheel nut up the flywheel spins on the collet (I have tried various collets) also the back of the flywheel is flat so its allowing dust & debris into the front engine bearing
Am i running the wrong flywheel?? I have been on amain hobbies website & noticed a different flywheel (OT FR 51) which could be the one i need
Any help greatly apreciated guys
Cheers
Steve

OT52 is the universal set for mugen aso..
OT51 is for Kyosho..
for the OT52 I had to use a losi cone
I think there is a special fioroniset for Losi ?

There are only 2 flywheels, you have the correct one. It is possible, although unlikely, you damaged the one you have and regardless of what you do it might not stay tight. Place a shim behind the collet, use a new collet (try the Losi one, if not try a Novarossi collet), and make sure the nut goes on in the right direction. If you look inside the nut, one side has a smooth area just inside. That side goes first.

As for allowing dirt in, every flywheel does. If you're getting dirt through the front bearing, you need a new bearing. This has nothing to do with the flywheel.

I used a losi 10th scale collet with a washer under the collet. I always loctite the nut on, I've had it loosen up several times.

+1 on a shim. If you are using the losi collet, you will need a shim behind the collet for sure. If you use a novarossi style collet, you will need to "shorten" it by sanding/filing some material off of the front(small side) of the collet. You can use a dremmel and sanding drum to remove some material. Sand it down a little at a time, and test fit it with the flywheel often. You want to remove enough material that the collet won't protrude through the "collet hole" on the flywheel. In other words, the collet should be flush or a little in from flush to the front face of the flywheel. This will allow the nut to tighten down on the flywheel, and not on the collet.

the Fioroni (OT FR 52) has a back to it that encases the bearing & the end of the crank case keeping most if not all the dust/debris out
I have never seen a flywheel with a flat back to it

It has everything to do with the flywheel! the Fioroni flywheel i have (OT FR 52) has a flat back to it thus allowing all the debris/dust to the front bearing,

I've had the same problem with the flywheel loosing up. I'm using the Lightweight Air Flow 3 Shoe (The orange vented flywheel) After the last time is loosened up, I took it all apart, installed a larger collet (The nova one) with just the flywheel (The shoes and adjuster off) I installed the flywheel and set the depth to 1mm of space from the front bearing / engine case. The flywheel nut is dome shaped, if some of the tapered collet does come past the flywheel, you can still lock it down. I think .5mm of the collet is protruding the flywheel. I reassembled and all is well. I have a set of new shoes in the mail - and I will be able to give more test results after the 12th as this is a bye race week.
Also - one thing to watch out for is the collet inside diameter. If the collet has loosened up and spun - it's possible the inside diameter could have opened up. I found one that was a fraction taller and the seam a fraction larger before installation.
