I need to pull the fan from the rotor so I can inspect the bushings. It appears they have two M8 bolts on each side of the center hole. It appear that the shaft of the rotor is threaded. I assume I need to thread a bolt into the center hole of the rotor shaft to pull the fan. My guestion is what size bolt do I need (3/8" or 10mm too small 1/2" too big) to thread into rotor shaft to pull fan? Or is there a special kind of wheel puller I need to get?

Centurion 85 - model #0046920
Fan, 12" curved blade model #0D8274

You would use a steering wheel puller and bolts threaded into the fan not the rotor.
The puller shaft would push against the rotor shaft. turn the puller shaft in until the fan pops off. Make sure the bolts in the fan are threaded in sufficiently and equally.

You need 2-- M 8 x 1.25 bolts (metric crap) 1 steering wheel puller about $15 at advance auto. Wheel pops off surprisingly easily. No problem.

Unless I'm missing something my fan is different. The center bolt is pushing against the same piece of metal (on the fan) as the 2 M8 bolts are pulling from. Using a standard puller will pull the fan into a U without putting any separting force from the rotor.

With the rotor bolt removed the hole in the fan should allow the puller bolt to contact the rotor shaft and not the fan itself. If the hole is not big enough
for your puller to go through you could put the rotor bolt in loose without the washer and press against it.

Duh... Pushing against the rotor bolt would have work. I wish I would have thought of that before I cracked the fan. Next time:-). Thanks for your help!!!
