I need to know what the difference is between a standard clutch and a diaphragm clutch. Is there any way to tell without pulling the tranny?
I don't think I am going to get the 4spd swapped for an automatic this spring after all and I need to get a new clutch. The parts books list two different styles and I don't know what my '68 F100 has.
Any help would be greatly appreciated. Thanks,all!
That could be. The parts books list two different types. I gues I'll just have to wait till I pull the tranny and see what's in there.
Thanks for the reply, though.
I didn't know you could get a diaphragm clutch for our year trucks, the original ones were the Long-style or standard. Would the throw-out bearing be the same?
You'll have to hear from the manual guys, I don't know how much you can see thru the bellhousing where the fork is.
Oh, no it describes the type of spring in the pressure plate. I was gonna try to describe the two but a picture is worth... well you know. Here's a link showing the different types, on top is a diaphragm style and the 5th one down where it says "older style" is the Long style with the three fingers.
Thanks, 68F250.
That helped. I guess I'll have to wait and see what's in there to know what to get. The LMC catalog refers to it as the "optional diaphragm type'" and lists one for the 352, 360, and 390.
I haven't had to change the clutch in my highboy yet. When I do, I'll be looking up a Centerforce II clutch. I'm sure they'll have one for the FE. Centerforce is a diaphragm design with weights. Clamps down on that disc hard without the added heavy foot pedal pressure.
Mont,
Don't know how well versed you are in clutch work so I'm throwing this out "just in case"
Don't dare replace that clutch without at least resurfacing the flywheel.
Please don't be mad, I've seen folks do it and wonder why their brand new clutch still sucks.
No problem Shrek....I learned that lesson the hardware years ago...but a lil reminder now and again never hurts.
