Last week my Predator seemed to loose all power, resulting in a auto down. I pulled the motor last night to discover one of the bolts holding the clutch to the fan was missing and the other was snapped off.

Any ideas on getting that screw out? The outside is a bit recessed, with only a tiny bit protruding on the inside. I tried a small drillbit last night, didn't seen to scratch the screw.

Have you tried heat? I would torch it up so as to get the loctite out of the way.

If it still doesn't come out, try freezing the clutch. The hole should get wider while the screw thinner...

Hope this helps.

I heated it some yesterday to hopefully loosen the loctite. The problem is there is almost nothing to grab onto to unscrew it. Trying to make a screw driver slot with an engraving cutter as we speak.

Ended up cutting a slot in the bolt with a carbide drill bit. On this day we give thanks for 30,000 carbide.

Came out real easy too, no sign of loctite

Actually I should have thought of that! I once removed a broken screw from an engine mount in that way.

Cool, good for you.

rcsoar4fun,

When you reinstall the clutch, I'd recommend using standard 3mm bolts, not the button head bolts, and use four of them. Additionally, use blue Locktie on the bolts, and red Locktite on the joint between the fan hub and the clutch. You should not have the problem again if you do that.
