I am a bit confused. The O-R clutch is only there to "absorb" the rapid increase in speed and let the flywheel spin the pinion forward at the diesel's idle speed, which is two to three times faster than the pony is running when at high speed. Once the diesel is running you disengage the pony drive pinion from the ring gear using the lever in the opposite direction that you used to engage it. If the O-R clutch has eaten a roller or gobbled a spring, it could be jammed, and that is an internal repair in the pony transmission. I doubt that you can turn the pinion backwards and get it to release and then function normally. Even if the O-R clutch is stuck, to get the pinion disengaged from the flywheel ring gear is the product of moving that lever in the oppoaite direction of engagement, not the O-R clutch. It sounds like you have two different problems: a stuck O-R clutch AND a pinion linkage that is not retracting the pinion when the lever comes back. Maybe even a third problem in that the pony cltuch doesn't sound like it disengaged properly, which again points to a mis-adjusted linkage. If you had a run away, I would STOP! Then go through the explanation and adjustment procedures in your book pertaining to the pony linkage adjustments. And plan on pulling the pony so you can get to the pony transmission. It only requires on gasket, a couple of bushings, and two bearings to totally overhaul it. The O-R clutch has some interesting problems, but they can generally be made to work well with just some new rollers, springs, caps, and a bit of home shop "machining" on the star driver ramps. If you don't fix it now, that pony will explode. Frank
