Leaking seal at solenoid shaft

I disconnected the electrical wires. Then disconnected the support strut and the two hose clamps. I was then able to remove the motor /pump assy where I completed the disassembly of the solenoid linkage and pump assy. I removed the solenoid shaft seal. I disassembled the impella parts & the motor shaft seal. I reassembled using new seals, impeller, and grader nut. The only tricky step was waking up to the fact of a left handed thread on the grader nut. I re-installed the motor/pump unit, tightened the hose clamps, connected the electrical wires, & support strut.
