Clutch ID question

Postby 64Khipo » Fri Sep 01, 2017 8:32 pm

Hello all--

I have a 64.5 HP convertible that had two Pasadena lady owners before me (really!) This month marks the 40th year that I have owned it. It may be the oldest K Mustang convertible in existence, having been built on June 9 1964.

Some years ago I replaced the clutch but saved the one that I took out of it. I would now like to have it rebuilt and put it back in the car, but I am not sure if it's original. The pressure plate is turquoise and the springs are a medium blue. No paint on the cover that I can discover (plenty of rust, though.) This description does not match the service manual, which says an original hipo clutch should have a bronze cover, pressure place and green springs. That, however, is for 1965 models and mine is a very early 64.

Could anyone please tell me what I have?

Regards, Chas Seims

I just sent you a PM on this but you will need to respond to my email address in the PM. That way we can work with pictures which can be tough to do on this forum.

If you need it redone, I would highly recommend this guy. He's been in the biz for quite a while, and took the time to give me more information than I could imagine. Very happy with the results.

Just curious why one would go through the trouble of rebuilding a 3 finger hipo clutch assembly today given that they have broken more than one z bar. My understanding was the center force clutch is a better option less likely to twist or break a stock hipo z bar?

The correct original Hipo clutch is not so tight as to break or bend the Z bar most of the time. I have run original Hipo clutches for years without any issues in all of my Kars. The problem with the 3 finger clutch is when people add more spring pressure to them or build a standard clutch with heavier springs. The standard clutch has counterweights which do make it tougher to depress at high RPM, especially with more spring pressure. I will however agree that the Center Force can be a good option today.

I've always used the stock clutch and pressure plate in three different HiPo kars: a '64 Fairlane. a '65 Comet Cyclone, and the '65 Mustang I currently have...The Comet had a clutch failure after I bought it in 1974, and I discovered it had a a very stiff aftermarket "racing" pressure plate installed by the previous owner. He was into drag racing the car, and also had a ANSEN scattershield, traction bars, headers and 4:11 gears. Anyway, I replaced the broken clutch with the stock unit, and never had any issues after nearly 25 years of use. I sold the CYCLONE to buy the Mustang. I'm not sure what the clutch setup is, but have a new stock HiPo unit ready to go if I need it.

What I was really asking is was this clutch originally installed in? Pressure plate is turquoise and springs medium blue. Does anybody have a service bulletin that would ID this? If it's a common piece, obviously, I won't redo it.

Thanks, Chas Seims

Chas, I am still waiting for your pictures in my email so that I can help you. Colors are unimportant.
