Didn't get as far as I wanted but did manage to cover a lot of ground yesterday.
Dewired it, starting over with a clean slate.
Kinda surprised to find this, I have seen them on other B/C tractors but tucked inside the frame I have never noticed them on a WD before. WD's originally had a magneto, the idea was the engine was easier to hand start with the clutch locked down so you were not turning the transmission in neutral through cold oil.
New legible oil pressure gauge. Not "correct" but it will work fine for what I am doing.
It is a little easier to make out over the probably original gauge. Looks like it was white face and said "Allis-Chalmers" on it.
Manifold gaskets are on. Manifold and carb are on and hooked up, didn't get a pic.
The lower hose is on which is a bugger being so far back in there and the modern stiff wrapped hose didn't help any.
Then comes the snafu, the alternator. Dang that is tight, the belt is still just barely snug and I am out of adjustment in the slot.
Well I will just slip that bolt out and try moving the bracket up to the water pump mounting bolt... nice.
Water pump bolt must have a bad habit of coming loose, we have three lock washers on there for extra security.
And it won't go low enough to reach the alternator and is already interfering with the throttle linkage. Dead end.
Modified it with the vice for a little more reach. Then it hit really bad.
Hated doing it but gave it a little more clearance with a grinder and smooshed it shut a tad with the vice. Belt is snug and everything clears.
Also changed the oil, torqued the rocker arm shaft down, set the valve clearance, put the plugs back in and put the wires on. New switches and ammeter are in dash and set the battery box on so I can start wiring. Getting dangerously close to starting it.
