Default Flywheel problem.

When i try to start my buggy on the starter box it only takes a couple of tries before the flywheel becomes extremely loose. But then i take off the clutch bell to tighten the clutch nut but it becomes tight again! I dont know why this is happening. When i take off the clutch bell the flywheel is not loose but when i try to start it, it becomes loose. So anyhelp would be nice.

this has happened to me too. it happens because of the direction youre forcing it. when you start it on the box it goes counter clockwise and loosens it, then when you unscrew the clutch bell its going clockwise and it tightens it.

take the clutch off and tighten the clutch nut up good and tight. should'nt be a problem after

seems like the flywheel nut is not tightened all the way. maybe when you take off the clutch bell, you are pressing the flywheel back toward the engine, which makes is seem tight because the collet is putting a bit of pressure on it. Thats the only thing that i can think of.

I use a really high-tech solution for this problem...

Clamp the flywheel in visegrips and put some A$$ on that nut! You'd have to be pretty stout to break the crank or strip that big honkin' nut.

Just FYI, I always, ALWAYS clean the crank, collet, (inside and out) and the hole in the flywheel with denatured alcohol beforehand... no matter if it is new or used. Get any oil off of there before you install it and it is easier to install (won't spin as easily when you are trying to tighten it) and grips better so it won't slip.

This is the problem. Happened to me too.

You need to use some sort of lock on the flywheel when you are tightening the clutch nut so that you really get it tight. channel locks, flywheel wrench or even pliers will do the trick.

For the losi 8ight vehicles there is a measurement of 23.3mm taken from shoe to shoe. This is the minimum value acceptable. I replace my shoes when the number gets close to 23.3mm. Here is a picture of how to measure with your caliper. (I didnt take it)
