In addition, pay attention to MC PUSH-ROD length(s) - C7TZ 2143-A (6 17/32") and C8TZ 2143-D (7")

1970/ is shown in the L SERIES CHART.

 

Kulutz,
I greatly appreciate the parts listing. I found a Booster part # C9TZ 2005-E. I found it online and the appearance looked just like what I have. Then I looked at the diameter measurement which was 13 3/16". Went home and measured mine and it is the same. Not sure where to go now, other than back to junk yards looking at donors. Would a picture of my brake pedal setup mean anything. I'm attaching a picture kind of hard to see though, but my brake pedal setup is much more heavy duty than other trucks I'm looking at. Also when I cross referenced the C9TZ 2005-E # a cardone booster kept coming up part # 54-73704. I looked much lighter duty. Any suggestions? The other picture is the booster I have and a number printed on it. I think that is just a Reman stamp number.

Thanks

You have to be careful of ILLUSTRATIONS on sites as the photo may not be the exact part advertised.

The C9TZ-E is (was) a SERVICE PART REPL for the original booster.

I think the problem may be either the linkage and/or push-rod length- Re-read POST #16 again.



Unless you have the correct push-rod and the MC to BOOSTER ADJ is correct, the brakes will never work correctly.



BOOSTER DIA should be 13.000".

Did you give parts man the MIDLAND ID NO?

 

KULUTZ,
i HAVE HAD NO LUCK FINDING THE BOOSTER IN LINE 108 C-4091-D/C9TZ 2005 E. I know this much my MC Midland Casting # 300371 which is midland part# C3472SD. All the research I have done says that goes with a 11 5/8" Booster Midland # C4028A listed as Ford F series 63-68. You have any info on those numbers may be a listing of brake shoe sizes for that set up?

Thanks
Southriver

 

KULTULZ: Look at line #108 and line #111 on the 2nd page: C9TZ-2005-E (Midland-Ross 4091-E) replaced C8TZ-2005-C (Midland-Ross 4091-D).

There are other applications for this C9TZ-E booster.

NOS PARTS SOURCE in Olathe KS has C9TZ-2005-EX .. Rebuilt Booster = 913-220-5746.

NOS also shows C8TZ-2005-C but it's probably this C9TZ-2005-E the replacement number.

 

THANX BILL!

The way I look at it, the VENDOR PN should be able to find a replacement vendor/aftermarket. The original FORD SERVICE PN was C8TZ 2005-C but then went to C9TZ 2005-E.

If I am wrong and he orders one of the two and it comes in incorrect, he might hurt me.

Now I am worrying if the MC is the same for MAN and PWR ...

 

I am consecrating on this, will get back later A.M. Let me go back through the thread. I may have tripped up somewhere.

 

I believe you are correct from what I can find from re-builders catalogs (online cataloging is a hit or miss).

PRECISION RE-BUILDERS ONLINE CATALOG -




I found what I think is the correct ILL last night under that PN but I cannot find it again. In lieu (Fr.) of the push rod out of the booster, it has a modified rod with a plunger on it to fit the sleeve on the MC. It was a 4028.




I am still searching as I know it is time to get back to work. Is the truck going to be used for grain or stone?

 

KULUTZ,

What is determined through your words or wisdom and research and working with a guy at Truck Pro and using Precision Rebuilders catalog is I have a truck with a perfectly good MC Midland Casting # 300371 Part # C3472SD. The MC is completely rebuilt with a stainless steel sleeve. The Booster which is rebuilt I don't have a part number or tag but measurements and all match the c 4091 d/C9TZ 2005 E. The MC and Booster just don't match. So the question is what direction do I head? Buy a MC to match the Booster or do the Opposite. I'm checking availability on both options. I get back to you a little later. Any suggestion you have I will take.

More info. When I got the truck it had little to no brakes. Wheel cylinders were leaking almost all the way around. On every wheel I replaced or rebuilt every component.. Then I had the the booster rebuilt (should have stopped before doing this because it had lug nuts fro spacers), and had the MC rebuilt. When I got the truck it had spacers between the firewall and booster. Without the spacers the rod is too long to connect to the pedal. Always had very little pedal travel, never felt front brakes engage, and the back always locked up.

I will be back in touch
Southriver

 

The firewall booster brake system is Midland-Ross. Used on lighter GVW 600s. I have 63 F600 with it on it also have 64 F600 that had it. Sold off several years ago on 64.

 

OK, after much consecration, I think that is what is going on is this-

1) The truck came through with A SGL SYSTEM vacuum boost.

2) At some point, someone tried to replace the correct style booster with a later model (or a re-man deviation).

3) There is no listing in the application chart FOR A 1968 MANUAL DRUM SINGLE SYSTEM, only SGL vacuum assist (short eyeballs on my part)..

It may be possible that one booster can be re-maned for more than one application. Your booster has to have the MC PUSH-ROD as shown below to match your MC (you have correct one according to chart)

Also notice position of check valve position on 300CI booster. Different from eight (previous ILL in above post).










The photo of your brake pedal was not clear. Is the assy 2B311 @ the brake pedal as shown above?

Crossing FORD VENDOR DESIGN is not always concise as FORD may require a vendor to modify to FORD specs.

 

..........

 

Yes. I am stuck in time, blue suede shoes and a cat hat ...

I corrected it. THANX for having my back ...

 

I edited and corrected it too...

 

Another revelation. The take-off booster was to be used with a remote vacuum tank (two inlets).



And I don't see C4028A listed in the original FORD APPL CHART. So it must be a later/replacement design.
