J/B Industries PR-308 Flexible Vacuum Pump Coupler Sleeve Only

This part broke and my generator and was more readily available than the Kohler part so I took the gamble and fit perfectly. Considering the application of both pieces I expect it to have the same longevity and will definitely order another for backup.

Perfect match

I chose the part for my pump per suppliers information. Easy to replace and worked perfectly.

Used this on a JSB 3cfm vacuum pump. Works like a charm. Material seems to be tough enough to hold up under normal conditions.

Easy to install , just remove 4 long bolts on back of motor , put the new one on the shaft , line up the splines and re install the motor. I guess the replacement green one will have a longer life expectancy or work better than the black one.

Fit my DV-142N perfect and got me up and running.
