Re: External Alternator Q's
I definitely understand what you are saying. I don't believe my pulley/shaft combo will be any heavier than the stock flywheel. The idea was derived from a guy I found on the net who dropped a GSXR750 into a Suzuki Samurai Rock Crawler. He attached a pulley the same way I am considering for both power steering and alternator. I am not sure whether he balanced his assembly or not. I do know he has been beating the piss out of it for at least a year without the slightlest problem in that area.
I think instead of welding the pulley to the shaft, I will machine the pulley for a hard press. The pulley bolt will come in on top of the pulley at approx. 80 ft. lbs. After I get the pulley pressed on I will take it somewhere to be balanced. Anyone see a potential problem with this?
The only issue I can foresee is compensation for the stock keyway. In other words, if I balance my pulley/shaft assembly off the motor, will it then be out of balance once I stick it on the crankshaft because of the little half moon? Or will the groove for the half moon make up the difference? I am hoping so. I am assuming the flywheel was balanced off of the crankshaft; therefore, I should be OK, no?
