Review on Efficient OTC (522) Large Gear and Pulley Puller for Easy Removal by Sean Young

OTC tool comes in two separate parts. When the spindle was screwed into the lubricated block, the spindle threads tightened almost immediately. Cause: UNF 3/4 " The thread of the block was not cut cleanly during/after tool manufacture. This is a typical error in quality control. With the new UNF 3/4" tap, I rethreaded the thread. During this operation (rework) many metal chips were removed. Wonderful! Now my tool is optimally ready for use.! Caution: Always use grease on the spindle. That's convenient.
