First step in remounting the PSRU, is to be sure the flywheel bolts are torqued at 80 ft lbs of torque. To accomplish this, it is necessary to fabricate a "ring gear lock" so the crank does not turn. Then goes on the PSRU, very easily done, just add the bolts to hold it on. The oil return from the PSRU to the oil tank might take a little engineering, clearance don't seem to be there for this fitting.
