 Topic: Distributor on a B...
Posted: 14 Dec 2016 at 8:57am |
Does it matter what spark plug wire I have #1 cyl. set to? Just curious, as my B has not started after we rebuilt it (the second time).... and it looks like it was running on just cyl. #1 and #4 (???) the couple minutes that it ran after rebuild number one (before it welded a bearing to the crankshaft.....).

Actually it does not matter where the wire goes to the distributor as long as it fires on the number one cylinder on the compression stroke. Then calling it number one and go clock ways on the cap for a 1-2-4-3 firing order.
It is easier to keep track of if you set it up as intended like in my picture.
On these engines the distributor is just tipped up 90ยบ from a magneto with the wires in the same locations

Okay, thanks DickL. I didn't think that it mattered, but I figured that it was worth asking anyway.  (just in case one or two of them were a tiny bit farther apart or something)
Steve: Not sure completely, but the fact that it ran a couple minutes without oil pressure probably helped, even though it still turned over a couple times after that.

I did put assembly lube on the bearings, and some was still on most of the bearings, just that one wanted to freeze up I guess. I did not prime the oil pump because I didn't know how to/that it could be done. But I am always willing to learn......how is it done on a B?

I don't like to leave something to chance that I can see so I do it a bit different than most. I put a rubber gas hose on the stand pipe in the filter base. I use a hose long enough to reach over the rocker arms. I fill the hose with motor oil and let it seep down then refill. I start the engine and watch the oil come back out the hose over the rocker arms. I then shut the engine off and replace the filter. I then start the engine watching the pressure gage to make sure I have oil pressure and watch for oil to get to the rocker arm assembly before putting valve cover back on. You just have to have oil in the pump to replace the air in the pump. With this pump the air has to be replaced with oil to pull oil up from the pan. If not it just spins in the air.
Lots of oil and assembly lube on all moving parts when assembling any engine is your friend.

Thanks DickL, that sounds like a good idea to me. I will have to give it a try.

as long as you have the wires in order 1-2-4-3 You can advance all the wires one position at a time and try to run it . one of those positions will be correct.

That is true....I will have to keep it in mind.
Should I have oil pressure when I am just cranking it over?

Well, it RUNS now!!!
Thanks to DickL, his method of priming the oil pump worked for me (and my help).
We figured out that we had the timing off by 90 degrees, so we fixed that and she fired right up....   |

I learned something to, the Model C I am restoring is my first Allis I have been around since the 70's when I was farming with a D21. I wasn't aware I should prime the oil pump before starting so rest assured I will do that, (just winding up my restoration). I restored my Fathers 1944 SC Case a year ago and didn't change the oil pump so I am now taking the pan off so I can rebuild the pump. The pressure is low and it just makes me nerves every time I start it. My C is a 1944. Thanks guys, I learn a lot reading your posts. now I just have to remember it all.
