Works well with seal installer 5209. I reused the hook type retention spring, I wasn’t satisfied that the twist-lock spring would stay in place. If any crank seal surface cleaning is needed I would suggest 1500 grit or very light scotch bright.

Great oil seal. The finishing and manufacturing features jumps out on your eyes way ahead from competition. It snapped right in after stretching it with the ATS tool. The only thing I did not like is the spring with the tread connection feature. I used the one with the hooks at the end from the other brand. Way easier to close the spring ring around the crankshaft. Run the engine for 7 minutes next day after 24 hours RTV seal curing. Works like a champ.
