Water pump pulley on a Cummins ISX on-road motor.

Looking to turn the A/C, alt, and possibly the water pump
electrically, when the motor is shut off.

Need the inner(rear) belt to be driven while the front is stationary,
(engine not running).

Would prefer that the main(front) belt being turned by the crankshaft
would cause the front belt to drive the rear, i.e. A/C & alt, without
needing to "lock" it up, electrically, or by air.

any thoughts, comments, suggestions gratefully acknowledged.




thanks
