Generator tooth

#1

Post by chuck58pan » Mon Jan 11, 2010 6:59 pm

model58 gen noisy when installed in fresh 58 pan. armature shaft at gear seemed to run-out .005. when disassembled the difference at the end cap bronze bearing was .007. the gear is 14 tooth not sure if it should be 13 also not too confident abou after- market gears, if in fact it is,an after-market gear. my quick fix is to go with a cycle-electric generator but now i wonder how the gear kit they sell will mesh. I have a 6v. solid state regulator . the motor sounded real quiet with the generator pulled other than a small tinny sound that hopefully willl be the oil-deflector . thanks for everything, chuck

I believe you need a 13 tooth gear,I bet it IS noisy!

the notes I have penciled in my parts book says 58 up generators use 13 teeth. It is my understanding either gear will work

Yes, 13 tooth and 14 tooth both will go. The 13 tooth is better for good charging in city traffic. As for the gear runout, I would be checking the armature for bent. If some one clamped the generator down without the correct shims, its possible to create a gear to gear no bacllash condition. and even so much pressure as to bend the armature shaft. The generator noise could come from insuficient ganerator gear backlash or maybe no back lash at all. Its not likely that the generator gear has a built in runout. Its just not the way of a gear cutter to be that hoaky...Joe

thanks for your input, i am more than willing to try 13 tooth as the gear that was on it made noise.the uncertainty is what i don,t like. this has been a wonderful and sometimes tortorous adventure getting this bike together, and i didn,t do any of the heavy lifting; i have a great appreciation for those of you who truly KNOW. thanks Chuck

Chuck:- The most important item to watch for is to be sure when done, you have some gear backlash. Best way to check is elbow grease. By that I mean pull the timing cam cover right off and then fit the generator with correct shims so as not to create any contact force on the gears and armature. Probably run with .005" backlash and if still whining, increase it a bit but I doubt you will need to go back in with .005" back lash...Joe
