Water pump renovation

I got to my sea-water pump today. Good description of the process can be found here.
The objective is to change two internal sealers: water and oil seal. One of them is probably causing the pump leakage.

Taking it into parts was easy - first came the axle with two bearings.

Gentle taping with wooden hammer got it out in no time.

The problem started with internal water seal. There is no way to remove these without damaging them and access is very limited. One needs to improvise a bit with tools.

In the end I managed to remove both seals. Unfortunately I also dented a bit soft bronze housing of the pump. That can lead to leak under the paper seal so I sanded the whole surface flat on 180 grid paper.

Both seals needed replacement. Bearings show no problems but the axis is a bit used. I would change it already now but this part was not ordered. If the pump still leaks after this maintenance then the axis will need to be replaced.

Assembling back all parts was easy. Special care is needed upon pressing down new seals so that they sit dead flat and all the way down in their cavities. Placing them right side up is also crucial, not to mention avoiding dents inside the bronze housing. Unconventional tools were called for.

Assembled back with new impeller cover - ready to be mounted on the engine.
