Sorry that no one has helped you get and neither can I but I do want to welcome you to FTE the best Ford Truck Forum on the World wide Web!

This will bumping to the top, however, and more guys will see it.

 

Part number for a '48-'50 is 7EQ2140. Probably the same for a '55 maybe. 1-1/2" bore.

I just bought a new one for my Trojan Loader Exact same one 1 1/2 bore NAPA. I didn't
say F800 Ford to Napa, I went to the Wagnor website and found the number and picture they
were or are used on many applications (like my loader)..sam

 

The original number for the F-800 (except tandem) master cylinder, Model QH, in 1953 was TFAA 22141-A. It was changed to B3Q 2140-A which is also then correct through 1956. It might be correct for later years too, I didn't check those books. Neither of the numbers are found on Parts Voice. Bill might have other leads. Stu

 

Not sure if there is a difference but according to the Chassis Parts Catalog, a 53-55 Ford F-800 (code QH) non tandem axle takes master cyl. Part number B3Q-2140-A

Hi Big Job... appreciate your info but could you provide a little more detail? Name, Model, and year of your loader... part number used and even maybe the website link etc. BIG THANKS Big Job. Darrell the Old Steel Man.

 

I try my best answer Darrell: Problem is most people go by say the Ford
part no. which is no good, all mfg. stamp their own part no. on a a part,
Ford did not mfg. master cylinders or wheel cylinders, these were from venders.
Most likely from the low bid, like Lockheed, Wagner, Bendix for example. Back to
my loader a 1964 Trojan. Its part no. is like 14 digits long worthless, Ford no.worthless Pretty sure it was a Wagner cylinder. I measured the thing and
some how I found Wagner web site with pictures. "bore, bolt hole dimensions" and
got their part no. went to Napa and had it after noon time. For giggles, I ask Steve
Napa with his computer, whats this fit? and he said you got the time? from IH Dodge
Mack Ford and a million fork lifts loaders and on and on. So yes the Ford number is obsolete, but does not mean the part is. just the Ford number is. Then when I got
it- identical to the F800 it now has a Napa p/n ? go figure, number games?
what ever you do, is not to go to Napa and say 55 F800 with a Ford number or a big
What !!! so go to Wagnor site or get a kid to do it LOL.....sam
