Glad there hasn't been any response to this thread_ means no one else has had to deal with this (yet).
I don't know if anyone cares to read the details, but here are a few notes for the archive:
You CAN remove the regulator (throttle) handle and shaft from the gear-cover by simply removing the governor cover on the front of the gear cover, remove the governor spring, tap-out the taper pin holding the lower handle to the shaft, remove the lower handle, and pull the regulator shaft out of the bushing. Make sure you hold the pin securely when tapping it out - you don't want to lose it inside the gear cover. The good news is you don't need to remove the whole gear cover like the instructions recommend. The bad news is if you drop the taper pin, you do need to remove the gear cover (and water pump, alternator, injection pump, flywheel, and "manual-start-handle cross-pin" in the end of the camshaft). Since I did that, I recommend carefully counting the number of turns when removing the injection pump limiter so you can put it back precisely where it was. Also, be very careful when removing the injector pump that the control rack does not catch/bind/bend on the gear cover_ go slow and easy. I found it easier, actually, to just loosen the injection pump enough that its cam-followers disengage the camshaft so the gear cover can be pulled-off. The only reason then to finish removing the pump is to replace the gasket, if you feel you need to. BTW - that little pin for the start handle is held in place by a socket-head cap screw in the end of the camshaft. Mine was obscured by dirt, so it took awhile to figure out how to remove it.
The regulator shaft is 8mm dia by 2" long, precision ground steel rod, cross drilled/reamed for the taper pins and grooved for the o-rings. Easy part to make, although some shops wont touch it if you tell them it's for a diesel (liability). I'm replacing mine with 8mm 303SS, available from Nordex in Danbury CT (800) 243-0986. Rather than wait 3 weeks for cut-to-length, I bought 36" for about $15. If anybody needs a piece, I'm happy to send you some. I'll never use the rest. I also have 36" of 7mm 303 for the cross-pin (don't ask). Oh, I'm not bothering with the taper pins. Will secure the handles with bolts, either with locking nuts or tapped into the handles.
