Review on 🚀 Ritchie Pump Drive Coupling for Yellow Jacket 93047 by Bob Roberts

My old Yellow Jacket vacuum pump removed the existing drive coupler. The original design was rather bad. A sleeve made of plastic (or similar material) connected the motor drive to the pump drive by small protrusions on the inside of the sleeve that matched the protrusions on the actuators. Excessive heat, aging, or both caused the plastic to warp and crack, causing the vacuum pump to stop working. I was very happy to see this kit. It replaces both the drive links and the crappy plastic grommet with a much stronger and more secure link/lock system. It's hard to describe if you can't see it, but it reminds me of Tetris :)
