Does anyone have the size of the output shaft for the new big fisher price cim motor after the belt sprocket is pressed off. A sketch of the length width and if there is a key would be nice.
Thanks, I don’t want to press the sprocket off to find out and the motor is on the other side of town.
I have it on reliable source that it is 5/16" with a flat ground on one side.
Yes, that’s what it appears to be. 5/16 and flat ground on 1 side. However, though it’s not a big difference, because it’s in the CIM family, might it be 8mm output shaft?
Hmmm I thought it was 8mm (.315"). It is only 2-3 thousandths of an inch differenence (5/16=.3125")
Anybody have a tie breaker?
I just check the step file on AndyMark.biz: Andy has modelled the shaft as 8mm with a flat at distance of 3.531mm (.139") from the centerline (= 7.531mm= .269" from the OD opposite the flat to the flat).
I hope this helps.
