Re: (ET) E-20 drive motor.

Another solution that has worked for me numerous times in the past is to take a pencil tip propane torch and a screwdriver. Heat just the head of the screw. Apply torque to the screwdriver to remove the fastener while continuing to heat the blade of the screwdriver. This transfers the heat to the fastener. Usually about the time the head of the screw glows red the fastener will back out.

Good luck.

This solution from early 1970s for loosening screw head bolts in aluminum motorcycle cases.

Use a manual impact wrench to remove the old bolts, then replace the bolts with allen heads.

Manual impact wrench available at your cycle dealer has the following advantages.

- When hit with a hammer the impact wrench (looks a bit like a fat screw driver) vibrates the shaft of the screw helping break it loose, provides pressure and turning torque at the same instant (to prevent tearing up the head) equal to how hard the impact wrench was hit (with a hammer). If this doesn't dislodge your bolts try heating the case a bit with a propane torch and repeat above procedure. Impact wrench costs about $12 with assortment of head screw sizes.
