The Seals

The Seals

Here are the actual seals. These two seals, when pressed into the pump body, are constantly separated by the spacer so they do not settle or compress against one another and risk oil/water or water/oil contamination. The spacer sits, and is captive, right over the weep hole to let a leak drain and become visible and detectable.

It is very important that the four little feet on the spacer face the oil seal when reinstalling the seals! The flat side of the spacer faces the water pump seal and the feet face the oil seal.

I have a 2001 Beneteau and I just removed the factory installed water pump, disassembled it and the spacer feet were also facing the water seal. Why is the direction important and where did Billy find the Westerbeke bulletin that specifies the spacer feet direction? Thanks.

Per your instructions I just removed the seals from what I believe is a factory pump that came with the generator. The spacer was in backwards in contrast to your instuctions. Searching I found a Westerbeke bulletin which had a parts diagram saying and showing the spacer with feet against the oil seal just as you instruct.
Thank you so much for this well made how to guide. Without it I would never have attempted this rebuild.
