Rotor 3aj
Hello,
Sorry but.. avoid hitting the crank with a hammer, it's really not good for the
bearings, they are allready the 3AJ's weakpoint on the rotor side.
Undecompressed cylinder, heavy rotor and heavy torque from starter engine makes them spin in case or on crank, at 100 000 K's crank can be demetalised enough that a new bearing won't fit.
The solution is to glue them with permanent lochtite.
Bearing don't like side forces, rotor will go off but the bearing might be nasty hit.
Try finding an inerty extractor and fasten it in the three holes, it hits also, but in the right direction !
Or build one, shouldn't be to difficult, three screws,one axle and a big weight
moving around the axle, hitting its end like a hammer when pulled out.
Or use a solid extractor and screw it out with WD40 and patience.
