Big progress, today. Got the half shaft out of the final drive. Turned the steering to the right. Put three 3" bolts in place of the FD bolts to the transmission; tow at the bottom and one at the top. I put my jack under it, and slid the FD back about 2" until it hit the tie rod.
I eagerly looked for the errant gear and pin on the bottom of the governor. Ahh, no wonder the governor wouldn't come out. The pin was sticking out about 1/2", in fact it couldn't have been hanging on by much. You can see the pin sticking out right below the female spline on the transmission. I was able to weasel in there with some lineman's pliers and work it out. I poked at the gear with a piece of wire until it fell out.
The smart guys call it "staking" the pin in, meaning take a modified chisel and bugger the ends of the hole the pin goes in so it can't come out. The PO made a weak attempt at staking the pin. I can see the marks but they are not much and the pin slid out. (I wonder if the roll pin is the right size?) A three second per side faulty bit of work with a chisel caused several hours of work. Not to mention driving 90 miles in low gear. Get 'em staked in well, when replacing a gear.
My my, the governor comes out very easily when there is not a roll pin hitting the case.
Speaking of roll pin hitting the case, if the pin is sticking out the governor can't spin. The gear made a mighty effort but no deal.
The three guide bolts worked like a charm. Remember, the jack it supporting the weight, but I have not moved the left wheel. When I was shutting the barn door the jack handle was sticking out a tiny bit. I gave a light push and the final drive slipped back into place. No lifting, no aligning. Manny taught me that.
Manny said the governor probably is damaged. (Four eager GMCers following the advice of many attempting to get the governor out. Just twist and pull and it should come right out.) I ordered one of Wally Anderson's rebuilt governors from JimK. I am betting Wally got the pin staked in properly.
