distributor to rotor clearance
I know that the clearance between the upper distributor body and the rotor should be .025 inches. How critical is this measurement? Two of the points are right on but the other two are maybe twice as big. The upper body is brand new. How will this affect how the car will run?
Thanks for any help. Marty |

Re: distributor to rotor clearance
If the ignition system is producing a strong spark, it probably won’t make a difference. But it could….
Check the play in the distributor shaft in the body of the distributor. It may be time to replace bushings and distributor shaft. You might also try replacing the upper body with another one - some suppliers like Brattons or Snyders will post information about the parts they sell that may be helpful. The body sold by Snyders looks pretty interesting. Good luck - Jim |

Re: distributor to rotor clearance
Bend the rotor to get the correct gap at the terminal that has the widest gap then file the other three down to get the correct gap.
I don't think I have ever seen one where they were all the same before adjusting. |

Re: distributor to rotor clearance
How does one bend the metal part of the rotor w/out breaking the bakelite (plastic?) part?
That's a skill I haven't mastered yet.

Re: distributor to rotor clearance
Interesting! The distributor body came new from Snyders and a new rotor, again from Snyders, will be here tomorrow. I'll keep y'all posted.

Re: distributor to rotor clearance
I keep original and 1930s replacement distributor bodies because they are much more rugged than the reproductions. Also, I believe that the Bakelite of the old ones is dimensionably more stable a material. Most of the old ones cleanup with Acetone / lacquer thinner and a coat of wax.

Re: distributor to rotor clearance
With an electronic ignition would you still keep the contacts between.010 and .015?

Re: distributor to rotor clearance
Where is the specification of .025 from?
The only specifications i have found in era books is .005 in a 1931 radio installation book |
