Bostitch Crankcase Bottom Belt AB9119273

Bostitch Pump Parts

Product Details
Brand: Bostitch
Part Number: AB9119273

Description: (M5 x 15mm HHCS) .

Replace if your belt is frayed or if you have more than 1/2" deflection (when pressing down at the centerpoint of the belt with your finger). A belt that is too tight can damage the pump and motor crankshaft and bearings; a belt that is too loose can cause low compression and the motor to run excessively hot, which can trip your electrical breaker. Always replace the belt if it begins to fray or dry-rot.
