Aluminum Castings

We typically have to clean up and weld castings to make them serviceable but these 250 water pump parts are too far gone. The material around the 6mm stud has deteriorated so it just fell out, and the pitting at the impeller surface negatively effects the flow of water through the engine. The bearing support plate is trash, it must weigh 40% less than it did when new.

With corrosion this bad on these castings, imagine what the inside of the engine block looks like! We are pulling the sleeves right now in order to inspect the block and possibly replace the sleeves if the wall thickness has been compromised by the rust.

I ordered some brand new castings to replace these and am anxious to see how they look and fit.
