Okay guys. I have to figure out what this transmission came out of. I know it was a 68 year modle car but i have to figure out which one so that I can get a clutch fork to fit the bearing that goes to the transmission.

Here are the only numbers that I can find on the hole thing.

On the side on the tranny are as follows== c8ar-7006-c

on the shaft end it reads RF-C5AR-7050

If anyone knows how to look these trannys up please let me know.
We are trying to install it in a 64 f-100 that has a 223 inline 6.
Thanks so much

Matt

 

Matt, there is another thread running this week that discusses this problem:

https://www.ford-trucks.com/forums/6...g-problem.html

I assume your car trans has a slip-yoke at the back and you are going to make a drive-shaft to use this yoke instead of the fixed yoke used in trucks, with a slip-joint in the driveshaft.

The clutch throw-out bearing is the heart of this swap, so you are on the right track to be checking out how to solve the problem. Part of the solution is to buy one part at a time rather than a whole clutch kit.

(I am in the same boat working on my '61 - 223 - T-98 4-speed preparing to change it to a 240 engine and who-knows which trans . . .)

 

The trans is from a 1968 Falcon/Mustang with a 289/302, the clutch fork used with this trans is: C3AZ-7515-C.

Every 1965/69 F100/350 with a: 240, 300, 302, 352, 360, and 390 engine used this exact same fork.

 

Matt,

This leaves you with pretty much the same throw-out bearing & fork problem as the other thread. There are several ways to solve this problem, as mentioned in the other thread.

Since you probably do not have the late bellhousing, which would not fit your engine without an adaptor plate anyway, I recommend you use the '64 parts you have:

o throw-out fork - leave it as it is (inspect for wear at the bearing end).
o use the flywheel you (have it surfaced, if needed)
o the throw-out bearing and carrier (or a replacement)
o the pressure plate you have (or a replacement)

Then all you have is to replace the driven disk with one that has splines that fit your transmission's input shaft and has the correct diameter for your pressure plate. AND:

Properly guide the big throw-out bearing carrier on the smaller input shaft bearing retainer on the front of your transmission. (The retainer bolts on with four bolts and is pretty easy to remove & replace if necessary.) Depending on what your old trans is, you might be able to swap, but be careful to make certain that the only difference is the outside diameter that the throw-out bearing carrier rides on. This will probably not be possible, SO:

Make a sleeve that can be pressed (or lock-tited) onto the input shaft bearing retainer to make it larger. This is a pretty simple lathe job. If you cannot do this yourself, any machine shop should be able to do this for you. You could also search the junkyards for a retainer that would work, but it would be a long shot, so I'd just pay for the machining. Just take in both retainers and tell the machinist you want the "new" one (fits the new transmission) to have the same outside diameter as the "old" one (off your old transmission.

(If you are junking the trans, the old retainer could be used to make the sleeve. Then all the machinist has to do is to bore it out and press what's left on the "new" retainer.)

Good luck & let us know how it comes out.
