Took the parts to the machinist today. May end up modifying the motor shaft rather than trying to incorporate the existing splined pump shaft into the coupler design.
The machinist hemmed and hawed about the pump shaft until I suggested we could change the motor shaft.
So maybe next week something will happen... One thing I know will happen is the total $ investment in the project will probably have increased by about 30-40% by the time we get out of there
This is an exciting part of the process... where all of the custom works really comes into play.
I was just thinking how useful this thread is going to be to a ton of people when you're done.
What is nominal shaft diameter of the armature? I would compare the adapter's diameter to that, not the tranny's. If it is smaller it could be a potential weak point... but really, how much torque is it going to be called upon to transfer?
It's hard to say because the emotor can put out so much instantaneous torque from a start that it can easily chew things up. Metro, maybe you should put some kind of damping circuit on the accelerator potentiometer to limit sudden increases (if your controller doesn't have this already). That "soft coupler" you have is very clever.
