Yellow Jacket 93047 Ritchie Pump Drive Coupling

Amazing

My older Yellow Jacket vacuum pump stripped out the existing drive coupling. The original design was fairly poor. A plastic (or similar material) bushing connected the motor drive to the pump drive via small ridges on the inside of the bushing which lined up with ridges on the drives. Excessive heat, age or both caused the plastic to warp and crack which resulted in no more vacuum pump. I was very happy to see this kit. It replaces both the drive connections and replaces the cheesy plastic bushing with a much more positive and robust connection/locking system. Hard to describe unless you see it, but reminds me of Tetris :)

Fast shipping, exactly as described

This unit fixed my Yellow Jacket Vacuum Pump and it is a real Love Joy coupler! Only thing I gave up was the sheer of the coupler is the pump froze up however the motor thermal overload will keep it safe. This is a far superior coupler than the Lexan Unit that came with the unit

works great

Simple installation, superior quality. The factory coupling was no comparison.

Great value and heavy duty!

Exactly as described. Fast shipping. Fixed the vacuum pump to perfection.
