leaking shaft seal

Well disassembly was good - removed the spring cam assembly on the dump valve cam, then two screws of the solenoid to remove the solenoid, beyond that the repair became a little tough since the seal / shaft retainer wasdifficult to remove. The shaft has a grove which the retainer clip is hard to remove from, and once removed - it deformed, so i installed the seal using a nut driver as a seal press to evenly press it into place. then had to work the retainer with a small set of pliers to reshape it, then reaasembled in place which is when i realized why it was hard to get off due to the shaft grove, which as well as holds the seal it also aligns the shaft latteraly in the pump housing, but after putting it all together and firing up the dishwasher, no leaks and it was an hour laying on my side which i feel was worth it, thx jon
