Yellow Jacket 93047 Ritchie Pump Drive Coupling

Solved my problem.

My yellow jacket 6cfm pumps works again.

The coupler from the motor to the pump on my Yellow Jacket vacuum pump broke from old age. What to do? I searched online and found that Amazon had a seller for the part. It was ordered and showed up within days. I looked it over and thought the wrong part had been sent to me--it looked a little different. It had the correct ends and was the correct length so I figured out that Yellow Jacket had made improvements to the coupler. End story is it fits perfect and the pump works great--thank you much!

As described.

Perfect fit

Great value and heavy duty!

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

The hardest part was getting to old coupler fittings off of the shafts. Man the manufacturer sure torques down those set screws! The price is a lot more than a replacement plastic coupler but will last forever. Well built and slid right on the motor and pump shafts. Its worth the price to have piece of mind that the plastic one wont crack and break over time. The rubber/urethane bushing will accommodate any minor misalignment and vibration without fear of breaking down. If you want reliability and a repair that will last the life of the pump, then get this coupler.
