Metal Bushings to make clutch have more grab

[Deleted member 35519]

First measure the outer diameter of the crank shaft rod in millimeters. Find a high grade 8 steel automotive bushing (washers) to fit as outer diameter of the crankshaft rods and the bushings diameter screwed on both ends to retain your Clutch spring. I couldn't find anything wide enough at my local hardware store. So I used a carbide bit to widen the inner diameter of the bushing washer. Everything else hardware store had was too was too large of an outer diameter for the washers.

I recommend using drill press instead. If you dont have one be a neanderthal like me.

Use propane and conventional oil to heat red hot and dip the washer/bushing in oil to cool down and strengthen the steal even more. I repeated this process 5 time each washer. Voila.

Now you have more grip on your clutch spring.


I highly recommend using an aftermarket clutch plate thereafter. This will give you your out of the box stock dlh clutch performance.

I wish I could calculate the lbs of pressure fom this. Other than buying that spring and testing it as you recommended.
