My new mechanic gave me a fresh perspective on why the pilot bushings are going out every 1500 miles. And he may be right.

The slave cylinder push rod is not perfectly perpendicular to the clutch fork. The rod is pushing up at an angle of about 35 degrees. He theorizes that the upward pressure on the shift fork is causing the fork to press on the input shaft causing the shaft to press on the pilot bushing thus causing premature wear.

We are going to fab a new slave bracket so that the piston and rod travel at a right angle to the clutch fork thus eliminating any abnormal force on the other parts.

Then, another bushing will go in and we will see what happens after that.

Makes sense to me now!
