Hello my learned and green-ish Brothers and Sisters.
My build:
1984 Jeep CJ-7 - Hyper9HV - IS
I've got everything but the adapter plate and coupler.
Todd at CAN EV is out and I'm not sure I want his standard one right now anyway.
At this point, I don't think it makes much sense to force the coupler to be the same crankshaft to flywheel bolt pattern as the original factory motor.
Given all the accepted knowledge that a lighter, aluminum flywheel is better, I'm going in that direction.
So, the question - I need a vendor / machinist / someone that can help in deciding if I should go with a keyed tapered shaft lock or an interference coupler.
The biggest downside to the interference coupler is, once you heat it up and put it on the shaft of your freshly bought $5k+++ motor, it's on forever. No changing it later.
The downside to the tapered coupler direction is the possibility of not being absolutely flat and fully 'down' on the new motor shaft.
But, if I'm reducing the flywheel to the lightest possible size (within safety and cost ~ 15 lbs or so), I've GREATLY reduced the compounding effect of the original design or the inertia stabilizing design of a flywheel.
So, maybe the combination of a light flywheel with a tapered shaft to a complete new flywheel bolt pattern might be better.
Thoughts? Anybody doing any work in this area?
Thanks,
Patrick
