Re: 1938 Ford truck distributor
Basically, the "extra" right point closes before the left one could close after firing. The early closing (only one needs to be closed to complete circuit) allows more charging time/dwell for the coil to recover for the next shot.
Cycle is thus: Both points open, 9 degrees after firing then right point closes and stays closed 22 1/2 degrees...coils starts loading Left point closes 9 degrees before the right opens,stays closed 22 1/2 right point opens...coil continues to charge then left opens, coil fires, repeat. Both must be open to fire coil, but only one needs to be closed to charge the coil, so that's how the overlap helps. Hope I got the cycle right...easier to follow if you rotate a distributor and watch than it is talking about it! I posted field-expedient timing method on here recently I think. |

I cleaned the "other" set of points at least 20 times trying to get spark. Glad to know today it is working as it should....I'm not sure how old that coil is but the darn thing is still working..... the coil says FORD on it. |

Re: 1938 Ford truck distributor
Mr Baker: I hope your having as much fun, as we reading what your doing, YES the 21 stud is a keeper....and what I see of your work, it going to be a truck to be proud of... must get the Ford green engine paint ...
Now the flip lever on the trans shift lever. you will need to pull it up/with your thumb, to put the trans in reverse. I don't remember is it up to the dash or down to the seat? Give me a break, it was 1941/42 war years all the men were gone, as a 10 year old boy I was put to work, the truck we had was ether 38 or 39 We did take the sides off the hood to keep it cool in the summer. Please tell us how good it sounds when it comes back to live .... OLD...BILL |

Good start on a nice pickup!! BTW, the "switch" or lever on the stick is the reverse lockout. Pull it up to get in reverse. |

That pic was taken when I pulled it from the barn..I have cleaned it up since then I have the caps fitting tight. The rotor does have step type brass points on it but the picture did not get that part. Do you think i need to replace that rotor it has been on there at least 40 to 50 years but it looks "ok"?

I already love the truck and plan to keep it like it is.....I was wondering about reverse and now I know!! Does that mean you can use reverse in all gears when you lift the lever or just when you lift the lever and put it in 1st? |

I can read the serial number on the frame next to the steering box and it does not match this trans number. Trans number BB18-2216590 clear as day. |

Re: 1938 Ford truck distributor
Reverse is all the way over right and down. To get into reverse use the trigger. It's an H pattern for forward gears and all the way right for reverse. 1st is up left and follow through for the rest of the gears.
Post some video when you get it started, if you will. Very cool truck. |

Re: 1938 Ford truck distributor
I worked on it about 4 hours today and had a few minor problems......I got my fuel line connected from the pump to the carb with new fittings and hose. I went to Napa, Carquest and autozone none of them had 18mm plugs for the engine but I finally found some at TSC....Autolite 386.
I got a "cut to size" set of 7mm plug wires from carquest also......my points have great spark but when I installed the plug wires and plugs I notice the spark to the plugs was very weak when I grounded the plug to the block....it was tiny. I also noticed some type of engine ground wire going from the cylinder head to the firewall on the cab....I may need to clean this well?? Should the condenser be grounded to the block?? It is connected to the coil but has some type of other piece hanging down like it needs to be connected to a bolt. Good spark to the points but weak spark to the plugs that is my issue now.....the rotor and both caps on the distributor that you connect the plug wires to are the ones that were already on it....I have not put in new points ,caps or rotor I just cleaned them up very well. |
