Description
The AR (Annovi Reverberi) Kit 42555 is a complete oil seal replacement set specifically for the RRV series pumps. These seals are located on the “dry-end” of the pump, pressed into the crankcase. Their job is to keep the lubricating oil inside the pump and prevent water or debris from entering the crankcase along the plunger rods.
If you see oil leaking from the area where the brass head meets the aluminum body, or if your pump oil has turned “milky,” these seals (along with the water seals) likely need replacement.
