Yellow Jacket 93047 Ritchie Pump Drive Coupling

Fixed my issue

Perfect fit

perfect replacement

Yellow Jacket is a good product BUT when repairing a vacuum pump, you typically need both pieces shown. Unfortunately what ships is one piece, so I returned it and used a less expensive one piece plastic sleeve which fits over both drive ends. I would have preferred the metal Yellow Jacket sleeves but the plastic will last for a few years

My vacuum pump original coupling finally let go. This was a nice quality and quick to install replacement and took about 20 minutes to change! Now its back in action.

As described.

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.

Great match to my old part.

Better than original.
