Starting problem

[Paul O Moen]

I have a 94 Force. Has been running great! until this week. Pulled the cover and found a small piece of magnatized metal, shinny smooth, curved on the inside and flat on bottom, broken away from the under side of the flywheel. I assume this is something to do with timing/ignition?Haven't pulled the flywheel off yet. Thanks

Re: Starting problem

Sounds like one of your magnets glued to the inside of the flywheel has broken off.

Re: Starting problem

Is this problem real serious this is a 94 on a 3yr rebuild. Are thes magnets easily replaced?

Re: Starting problem

Magnets are easily replaced if you could find them. I'm not aware of anyone that sells just the magnets for the Force flywheels. Your best bet is probably a used flywheel from E-Bay. Sounds like you have the flywheel that has six separate magnets on the inside circumference of the flywheel. You need to confirm this. The older style flywheels has a single somewhat flexible strip magnet that runs along the inside circumference.

I ran into a similar problem on a recent project. I discovered that you have to be careful of the diameter of the hole in the flywheel. There are two styles of flywheels that have the six magnets.

1. Older style that is used on ignition systems with a switch box has a hole that is approximately 1 1/16" in diameter on the bottom. Hole is tapered so top diameter is smaller than the bottom. Flywheel has 3 bolt holes for a puller to remove the flywheel.

2. Newer style that is used with CDM ignition system (no switch box) that has a hole that is approximately 1 5/16" in diameter on the bottom. It also has the three bolt holes for a puller plus a quarter inch thick lip that sticks up about 3/4" high around the hole on the top that has internal threads to use a different type of puller.

Remove your flywheel and take measurements. Match it up with the one you purchase and you should be good to go.
