As for the pulley removal, I used none of the little adapters, I just used the “center screw” along with the two half moon clamps and the sheath with the “puller body”. Not a lot of working room, with any of the little adapters, I no longer had room to put a ratchet on it. And I needed something with more leverage than my little 1/2” box wrench. Every video I watched showed shroud and fan removal, but I have have e-fans, so I didnt do that, and it was tight. Was able to use a 1/2” socket and ratchet, and a big wrench (21mm?) resting against the frame to pull it off. Putting on, I used the longer screw adapter. Screw it into the center screw, then thread into the pump shaft. Then the position the pulley and then the bearing. The bearing washer was missing from the kit. Then the puller body again. Start muscling it on with the big wrench while holding with the small wrench. I measured with my micrometer the gap of the pulley to the bracket body before I took of the old one, so I’d know when to stop. Since you can’t see when the shaft end is flush with the pulley. Not terribly difficult once I figured out which pieces and how.
