Harmon Collins

A while back I read somewhere on here that someone bought out the remaining stock of Harman Collins, that person also has the rights, and was a member on this board. I tried the search and WOW there is alot of entries refering to Harmon Collins, couldn't find what I was looking for in that sea of information.

Who was that?

I am looking for some cam spec for Harman Collins and who better to ask. Hopefully they kept all the early cam documentation.

Thanks,
Jim

It's in the "my new AV8" thread by myke.

 

Which "my new AV8" thread there was more than a few and none started by myke.?

 

When H&C split up many years ago as I understand it Kenny Harman got the cam business and Cliff Collins took the ignition side of it. Kenny ground cams here in San Diego for many years specializing in motorcycle cams from what I understand. At some point in time Shieffer bought out Collins and started selling the Mags as Schieffer units. These were basically identical except they used the H&C dual coil style rotor (without the second coil brush) and a cap adapter to increase the clearance for the larger style rotor and to take a stack type cap not the crab style. At some point the magneto housings went from sand cast pieces to die cast. There were basically the same except the die cast ones had spring type hold downs for the cap instead of the screw down type the crab caps used. The main magneto shaft was also longer to accomodate the new rotor. Scheiffer also made coils potted in epoxy.

Shieffer ended up selling the magneto stuff to Cirello magneto. I used to buy replacement parts from Cirello in 1989/90 and they had ALL of the tooling, misc spare parts etc etc etc. Cirello sold all of it to a guy here in San Diego who used to work for Collins and Scheiffer who was going to produce point coil ignitions from the original tooling. He had come up with a conversion that kept the look of the mag without all the issues they had. He sold the stuff to Nostalgic Hot Rod Products in Orange County, as far as I know they have it now.

The flathead drive pieces that are usually missing are available from Speedway Motors, a 3 piece set drive tang, collar, and spring.

As I recall lead can be adjusted by degrees by advancing the collar one spline clockwise on the magneto shaft and advancing the drive tang one spline counter clock wise. I can't tell you if that advances or retards but it wouldnt be hard to figure it out if you have a unit.

NHRP does not own the name Harman and Collins or the 2 logos.
