D4 7U water pump rebuild

I will have the seals and brgs. Tuesday of next week for my D4 does anyone have any advise or things to watch for when im rebuilding this pump? Seems like its pretty straight forward but I have easy things go really bad before. Thanks for your advise Dan

Most important point, do not pull on outer rim of pulleys or impeller. Use the bolt holes and a steering wheel type puller plus heat if needed. Get pulley and impeller off and remove seal etc and then clean the housing with a sharp screwdriver, solvent, compressed air etc and look for snaprings. May need to dig out the grease seal behind the pulley and look inside the housing there too.

I have never seen a D4 water pump, there may not be any snap rings in it, but missing a snap ring in a bunch of dried grease is a sure way to make your water pump rebuild into an ordeal. 😆

Once you have them all out or are sure there aren't any, then you can carefully press or drive the shaft out. Make sure you understand which way it goes. There will be a shoulder in both housing and on shaft for the bearings to rest against, which should prevent things from going the wrong way.
