Hello Eric,

A good trick for replacing an impeller is to squeeze it with a plastic cable tie so that it will go into it's housing and key wat easily. The housing should be greased and the impeller greased or sprayed with silicon. Make sure that all the vanes are pointing the same way as you tighten the cable tie and that they are pointing the right way (usually anticlock wise) when pushing the impeller in. best wishes, Anne and John, SM319

But these are some of the things you should considering when you are inspecting the pump. Check and see if you can get your hands on the Workshop Manual for your engine, you will find it invaluable. You should also be able to get detailed drawings of your pump on the web by typing in the make and model number.
