Lapped housing and spacing question
 

I have an argument with a friend via AIM on the spacing issue. I want to hear you guy's opinion who has rebuild motors before and understands internals of the motor. If the iron housings were lapped. The motor itself will be shorter due to less materials. However, My argument is that you don't need to change the spacers(the one between the needle bearings). The reason behind this is that the spacing was determined by the rotor lobe of the E-shaft in respect to the end of the stationary gear. eventhough the surface of the iron housing has changed, the stationary gear that mounts to the side of the housing hasn't been touched so that the overall length of the E-shaft remains the same in respect to the motor before lapping (because the length of the stationary gear, counter weight, needle bearings, spacers, oil pump pulley, OMP gear..etc remains the same). The stacking should be the same. The rotor however will ride closer to the stationary gear because the motor is shorter but I don't see any reason why the spacing will be different. anyone care to comment on this?

Damn, there was a topic about this not 3 days ago somewhere, I'll see if I can dig it up.

Oh yea, there were argueing about it, some were saying what you said and some were saying otherwise. I dont know what the outcome was. Maybe I can find the thread.
