That's what holds the hub onto the crankshaft. The fan is separate from the hub, and once the three bolts that hold the fan onto the hub are out, you should be able to wiggle the fan until it comes off.

Yup, but for some reason mine had an oversized washer that sat in front of the fan, with a spacer between the hub, and it was put on with red loctite. I can only assume the PO or whoever rebuilt the motor didn't have all the rift parts/knowledge. It also had a black plastic snap cap/insert into the bolt so I couldn't tell... it was an Allen key bolt. That was a core 1.8 motor I bought for $125 on CL....
