Yellow Jacket 93047 Ritchie Pump Drive Coupling

Pump came with a metal and plastic coupling. The plastic got brittle with age and broke. This coupling is one heavy duty metal assembly which is easy to install and will never break. Highly recommend this product!

As described.

Perfect, Thanks!

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 :)

It fit perfect and was very simple to replace the old one with the new one

got the job done. What else is there to say?

Great price
