Most rebuilds take the wet-end seal kit (fluid leaking at the casing or dripping from the slinger) and, if oil is weeping between the motor and pump, the motor seal kit. Not sure which motor you have? Send a photo of the motor end and the nameplate to sales@spraycenter.com or call (509) 838-2209 and we'll match the kit before you order. The detailed service parts list below follows Hypro's parts breakdown for the original motor; motor-side parts differ on newer motors.
