alright. I got a question. I have a 1964 ford f100 292 v-8 with a t-98 4speed behind it. the truck is 2wd. what size clutch does this thing have. The parts store I always work with show only a 12" clutch kit. How are clutches measured??? Is it measured by the friction disc????? is ther any way of telling what clutch size is in there without ripping the tranny out????? What is the input shaft diameter/spline count????

 

If it's like the FE series that replaced it, your Y block should have an inspection cover on the bottom. I think four bolts hold it on. You can't really access anything to work on it but you should be able to get a tape up in there to see what the diameter of the disc is. Steve

 

B4AZ6375B .. Flywheel ~ 14 13/16" O/A diameter / 146T ring gear / Use with 10 1/2" or 11" clutch.

(6) 5/16" -18 pressure plate attaching holes on a 12 3/8" bolt circle.

Fits: 1961/64 F100/250 292 w/a 3 or 4 speed manual transmission.

11 1/2" or 12" clutch: ONLY F350/750's w/a 292.

 

but i have to tear it apart in order to find out if i got a 10.5" or 11 clutch right???

 

It's prolly an 11" which was faaaar more common than the 10 1/2."

Considering that the exact same flywheel was used for both sizes, just get the 11" clutch.

 

alright thank you. got one more question. when my clutch went out, it makes this rattling noise. almost like a baby rattle. I am believing that my friction disc went bad because i can still feel pedal pressure. that hasnt changed which tells me that the pressure plate and throwout bearing is still good and in one peice. Am I pointing in the right direction???
What happened was i was on my way home driving down the road and then all the sudden i lost power. I can let the pedal out in gear and get nothing.

 

ok. Y is it when I go to an autoparts stores website to look up the price for a clutch kit for my truck, it always shows a 12 inch clutch for the kit??????

 

I don't give a rats behind what some autoparts stores parts catalog says.

The info I posted came directly from the 1957/63 and 1964/72 FORD Truck Parts Catalogs.

11 1/2" or 12" clutch: 1961/64 F350/750. The flywheel used with the 11 1/2 or 12 inch clutch was not used in F100/250's.

F350/750's w/a 11 1/2" or 12" clutch's flywheel has a 12 7/8" bolt circle. F100/250's w/a 10 1/2" or 11" clutch's flywheel has a 12 3/8" bolt circle.

If the disc has worn down to nothing, this may have caused the flywheel to burn, usually blue heat spots are present.

If this occurs, you'll have to replace the flywheel.

Once a flywheel has fried, resurfacing it won't do one damn bit of good.

 

hey ND, calm down.lol. I was asking as to hopes there was a reason like the kits are measured by the pressure plate not the disc..lol. thats all i was asking.

 

The clutch is measured by the disc, not the pressure plate.

I've never heard of one clutch being measured by the pressure plate...regardless of what make of vehicle the old rolling pile of miseries is.

Do what 59INA40 suggested in post #2, remove the inspection cover, and measure.

 

i think what happened is that the hub broke away from the rest of the disc.
