Hi there,

I have got a 55 F100 and now after I finished restoring it I found out that the clutch or the flywheel is damaged and I need to replace it because driving is definiteley no fun.

The problem is that I don't have any idea what clutch or flywheel I need.
I have got a 1968 302cui with a manual Ford 3 gear (RAN E2). I know that the clutch hub must fit on the gear shaft (That is the only thing I know for sure).

But what about the size of the clutch and the flywheel? So far I came to the conclusion that the flywheel must fit the engine and the clutch must fit the flywheel (so if I have a 10.5" clutch I need a flywheel that fits it). Am I right here?
And does it matter if I have a 10/ 10.5 or 11 inch clutch?

Thanks for your help so far.
Andy

 

My '65 289 2V 3 speed had a 10.5" clutch, so that size is fine for what you are doing.

The flywheel is bolted to the crank. You will remove it and have it resurfaced. It is what it is, unless you want a bigger clutch and it won't accept one. Then you buy a new flywheel. But for now, we assume you will use your existing flywheel, resurfaced, with your existing clutch size.

The clutch disc must have the same input spline and diameter as your trans. Take the old one with you, no issues.

The pressure plate, which bolts to the flywheel, must match the disc for size and match the flywheel for the bolt patter. Take the old one with you, no issues.

You also need a throw out bearing and pilot bushing. Wait for it....take the old ones with you.

If the engine and trans was a set out of a known car or truck, you could buy all this stuff in advance using that car/truck info. If you don't know where it came from...take the old stuff with you.

Opt for the "heavy duty" set up if offered.

DO NOT cheap out and leave your lumpy burn marked flywheel as-is.

Chatter can be good but not when it's your clutch.

 

You ought to get a new ring gear while you're at it whoever resurfaces it should be able to change it

With a 10.5 clutch it should be 157 tooth if yours has 160 it needs a 157 tooth replacement as far as I know anyway mine had a 160 but I kept the ring gear
