67 427 Starter solenoid insulation

[Charles A.]

I acquired a 1107365 starter and solenoid that was restored by John Pirkle a long time ago. The solenoid has insulation on it that looks like spray on fuzzy stuff. Is this correct or just something to shield heat or both?

If you're talking about an insulation that covers or mostly covers the solenoid, that's definitely NOT correct. However, I seriously doubt that John Pirkle would have done something like that. If you're talking about a little bit of "squeeze out" of a foam-type sealer near the interface of the solenoid and the starter nose, that's DEFINITELY CORRECT. That's how these starters were originally built. You'll almost never see this in a commercially rebuilt starter since this feature is usually omitted.

Charles -- here's a shot of a new 1114356 solenoid, similar to what was installed on starters in the mid '60s. There is a rubber "gasket" between the metal body and the bakelite (?) cover with terminals. This is a smooth rubber, pliable and soft.

Thank you. Very helpful

Great shot, Wayne. Thanks. Ridge

Just to be clear, the interface between the cap and the solenoid body is not what I thought the original question was about and, certainly, was not what I was referring to. The cap-to-body junction was always sealed by a rubber gasket as far as I know. I was referring to the interface between the solenoid body and the starter nose. That's where the "foam-like" sealer was used.

OK, Joe, now I get it . In the NOS box in my pic, there's detailed instructions on replacement (dated July 1963), with no mention of (re ?) sealing the solenoid-to-starter nose. But I suppose John P. has seen a lot of originals and is restoring accordingly.

Re: 67 427 Starter solenoid insulation

Were all the solenoids painted black?

Re: 67 427 Starter solenoid insulation

Yes, Charles. The body was painted S-G Black.
The near half in the picture with the terminals was a "Bakelite" type material. Not always as crisp of a black.

Sorry, I didn't key all that I was thinking. One of those late night disconnects.
I should have elaborated to say; the near end was a natural unpainted type of black "Bakelite".
Or words to that effect.

Re: 67 427 Starter solenoid insulation

Not all the solenoids were painted black.They also could have been silver zinc plated I have photos of the assembly line in the late sixties with a protective clipon shield over the plated solenoid as the starter goes through the paint process. Dad has had several interviews with assembly line workers that confirms the photos information. We have not been able to determine any rhyme or reason as to why some were plated and some painted,or that the year has any bearing on which would occur

Glad to hear from the source. By the way how is my alternator order doing?

Re: 67 427 Starter solenoid insulation

Is the starter in this picture painted correctly?

That being the natural unpainted rear casting?
