Just replaced the seals and shaft in my 03's water pump. Indy gave me the parts list and if I would have ordered the numbers he gave me everything would have gone smooth, BUT, I didn't. Anyway I did it and if I can, anyone can. Here are the part #'s and some photos to go along with it. Parts to order: #5GR-12458-00-00 SHAFT, IMPELLER #93109-11073-00 OIL SEAL (water side seal) #93102-12321-00 OIL SEAL (SD 12-22-5 HS) #5TA-15462-00-00 GASKET, CRANKCASE COVER 3 I started by draining the coolant and taking off the header pipe. http://i24.photobucket.com/albums/c18/ta2240/SideAtt.jpg http://i24.photobucket.com/albums/c18/ta2240/Drain.jpg Then removed the side case. http://i24.photobucket.com/albums/c18/ta2240/Sideremoved.jpg Here is a photo of the outer water seal and impeller with the shaft already removed. The shaft just pulled out and the inner oil seal hammers out with a punch along with the bearing. The water seal popped out easy http://i24.photobucket.com/albums/c18/ta2240/Waterseal.jpg Here is a photo of the bearing with shaft still in. http://i24.photobucket.com/albums/c18/ta2240/Bearing.jpg Here are the groves that everyone keeps talking about wearing into the shaft. The old one is on the left and the new one is on the right(It will be obvious) http://i24.photobucket.com/albums/c18/ta2240/Shaft.jpg I hope this helps somebody. I am a coward when it comes to this kind of stuff but it was easy.
