Steve,

You can't do that on the "B", because the oil pump drive is all on it's own, and the distributor does not mount on top of, and plug into, the oil pump, so there is no access from the top to drive the oil pump.

You could pre-lube it by buying a cheap plastic pump up garden sprayer, and putting a quart or two of engine oil in it, making an adapter to attach it to an oil gallery plug, (or the threaded hole where the oil gauge attaches). Pump pressure on the sprayer, and your engine will be pre-lubed. Shut the valve on the sprayer wand off just before the oil is all forced into the engine, so you don't inject a bunch of air.

Professional engine builders use an industrial strength version of this system.

On an engine with unusually low oil pressure, this can be used as a diagnostic tool by dropping the oil pan, and pressurizing the oiling system from the external source. You then look for the area of the engine leaking the most oil, such as a bad bearing, or a missing internal oil passage plug.

The alternative is to remove the spark plugs and crank the engine over, or tow the tractor slowly, until there is oil pressure.

Some engine rebuilders pack the oil pump with petroleum jelly (Vaseline) for faster priming. The petroleum jelly harmlessly disolves into the engine oil after start-up.

It is an old-timers trick to put a couple of extra quarts of oil in a newly rebuilt engine to aid lube on initial startup, and then drain out the excess.
