It utilizes a 3/8" spherical rod end. I also added one at the clutch pedal attachment point. It should keep from wearing the holes out like Ford's setup did........I will try to get a better pic of it today

 

Moderator: I think it would be a great idea, and a service to your members, to create a sticky of ZF info.

For those searching for a great source of info regarding the ZF, photos and diagrams, schmatics, etc., take a look at this:

That is the clutch pedal system I will follow. It is a fairly simple way to brace the firewall, with zero chance of flex or crack, ensuring full engagement/disengagement.









Having the pedal assembly out of the truck makes it a breeze. This is, of course, for mounting the clutch master on the drivers side of the firewall. This seems to be, so far, the best system for what I needed.

 

F250 RESTORER the link you posted was great but my firewall/inner fender look different than any other one I've seen. I would have to mount the master cylinder inside the wheel well. My truck is a 1974 F350 SCS if that changes anything.

 

Does anyone know who posted these photos? Or the parts used to make the conversion?

 

I think you will have to mount the clutch master on the passenger side of the brake booster. Look at the other pix in this thread. Many of them are doing that because of lack of space.

 

Dang, at the j/y today and found a nice sb ZF, a 91. It has writing on it, as though rebuilt. Oh well...bet it's gone tomorrow.

 

If anyone would like to change from the plastic Ford bushings to sealed bearings, and never have to bother with it again, I found a source for the Kit:
MustangSteve's Clutch Pedal Shaft Bearing Conversion for 65-73 Mustangs

I'm wondering how long it takes the plastic to wear out. I mean plastic bushings in the pivot of brake and clutch pedals? Ouch.

 

This is a great upgrade to your clutch pedal. Used this on daughters '67 mustang and my truck, improved pedal action on both.

 

Hey guys, I'm searching for the slave hose release tool, and can't find it. Am I calling it the wrong name?

Does anyone know where I can buy one?

 

Instead of fighting with that big Vac-U-Suck brake booster, why don't you guys switch to Hydroboost?


Also, I did the rod end conversion on an old IDI I used to have, and it was awesome.

 

I run h.boost brakes. It was one of the best mods I've done to the truck.

 

I've done both the ZF5 and Hydroboost. I read somewhere a long time ago while I was researching my Hydroboost conversion a quote that pushed me over the edge to do it. "If you want a come to Jesus meeting with your steering wheel the mod is for you!" Hydroboost is on my "must do" list now. The ZF5 just makes everything that much sweeter.

Has anyone found a sourcefor the clutch fork dust boot for the ZF5?

 

I found that with the hydro conversion that it created the need to change to a Saginaw p/steering pump. Without it, there were moments in parking lots, where the steering aid just sort of vanished or got slow. I went with the p/s unit off a 76 ltd with a 460 and hydro. I also used the bracket off an 80's Econoline with my engine. I didn't use the pump from the Econoline b/c I wanted the dual return inlets found on the LTD pump.

I'm also, as I wrote about in another posting, changing from the busings to bearings on the pedal assembly. Of course that meant I had to buy a new welder ... and on it goes. My garage has become a combination of repair shop/parts house for the truck.

Oh, btw, found a clean f250 with a zf5, and pulled the driveshafts and rear end yolk for $50!!! Happy day.

 

Off-hand ZF-5 question? Are all ZF-5 clutch forks the same? I just picked up my ZF-5 today, but there was no clutch fork. Now I need to find one.
