Heya guys, need some help on this one form south Africa here and nearly complete to finish my rebuild on my F250 and now I wanted to replace clutch and slave units while im busy and behold our Ford dealer informs me that they no longer keep these units, so could anyone help me as I see afew in ebay. its the 4.2l unit

 

The 4.2 uses the ZF5 (essentially the manual transmission behind older F-Trucks that were sold in the US up to 1997).

I would guess that their master/slave would be the same, but could be entirely wrong.
Here are some example parts off older F-Trucks in the US:
More Information for DORMAN CC649005
More Information for RHINOPAC / WORLD CAR PS0713
Do they look similar to yours?

Here is one for a similar year to your 7.3 (fitted with the ZF-6, different trans)
More Information for RHINOPAC / WORLD CAR PS0722

The only thing that in my mind wouldn't match up is the hydraulic line, but you should be able to reuse your existing one.

Also, bear in mind that this is free advice from someone that hasn't looked at a 4.2l F-truck for almost 10 years. Take it for what it is worth

 

THANKS a lot really really appreciate it, heres some pic maybe you can make more sense of it, I just wanna buy master and slave to have as a spare

They are all pictures of the slave cylinder, correct?

Do you have pics of the master cylinder?

 

Unfortunately the photos you have taken don't really help in identifying what master/slave kit is fitted to your truck.
All you need to know is if your master cylinder has the overflow reservoir attached directly to it (old style that I linked), or if it is mounted separately on the firewall (same style as the newer 7.3 trucks with the ZF6).

If the reservoir on the master cylinder is a part of housing, find a pre 97 master/slave assembly for 7.3l US truck. If the reservoir is separate, find a 2000+ master/slave assembly for a 7.3l US truck.

I find (site sponsor) RockAuto Parts Catalog a good place to find parts.

 

The overflow reservoir is separate on the firewall and has pipe attached to the top part of the master.

 

Ok, it is the same as the 2000+ 7.3l master/slaves. Here you are:

 

Fantastic thanks again for your help. going to order now
