These recommendations also apply to any service work on the pump and its components that require the use of lubrication inside the pump for assembly and start-up. Your engine should be run after installation of a new impeller to wash out the lubrication. Lubricated impellers should not be stored for extended periods of time. Mount the impeller by making a pushing and twisting movement in the rotating direction. Start by lubricating the shaft, the inside of the pump body and the end cover which will help when inserting the impeller and prevent damage from dry-running the pump at initial start-up.
