I am in the process of doing EXACTLY what you are doing. I got the rebuild kit $40. Removed the pump and started tear down. When I removed the shaft, there was quite a bit of pitting on the shaft under the main seal (guess why it wouldn't hold pressure). Bought a new shaft $50. Took the middle section to the dealer to replace the valve seats with the ones in the kit $30. I still have to remove the bearing race to get to the seal. I am planning on using a dremel tool to cut up the seal and bend it out with pliers. Then I have a grade 8 3/8" bolt and nut that I am going use as a jack screw and put under the race so that I can bang it out from the other side. Then I will decide if I need to replace the needle bearing $7. I considered buying a pilot bearing puller to remove this race. I may yet change plans. If you do an archive search on this site there is a better description of the jack screw/bearing removal process. The video does mention it, but there is not any footage of the process and I don't think there is enough detail. Take plenty of open workbench space to spread parts out because there are a bunch of parts. I hope to complete this job this weekend, but you just don't know. I have the better part of a working day into it (not counting waiting for parts and stuff), $120, and estimate the better part of a day (and maybe a few more dollars) to complete it. Good luck.
