Hi all trying to determine which drum part number my drums are I flipped through the parts manual but I'm a little confused on which one it could be there are so many options can anyone help and does anyone know where a good source of drums might be?

My axle is a Eaton model 17171 Single Speed Rear Axle / 6.50-1 / 18,500 lbs

 

Others here report there are no new drums to be had. So you are looking at a junkyard type search.

Do you have any way of determining the dimensions of your brakes? Diameter and shoe width. Using the manual as a guide, and knowing the possible diameters, you may be able to get the actual dimensions.

Easy for me to say I know.....

 

Front brakes, see upper pic under C800:

What is the 3rd digit of the AXLE code? When decoded, the weight capacity of the front axle will be known. Also need the size of the brake shoes.
------------------------------------------------------------------------------------------------------------------------------------------------------------------
Rear brakes, see C800 in lower pic. Weight capacity is known (18,500 lbs.), but now I need to know the size of the brake shoes.

 

Where are you located, I have a 68 C800 28k mile former fire truck (engine blew so I'm parting it out), it's set up for Dayton wheels. Should have a good set of drums, these won't work if you have Bud wheels.
It's in central Ky.

 

Hi - I am a newbie from the UK and have an ex USAF C800 - year approx 1985 (I think). 8.2 detroit diesel - I am hoping to turn it into a ramp truck for my 1930 chopped model A sedan race car.

Unfortunately, the army decided to take the rear brakes apart and remove ALL of the internals!!

I am not sure where to start to get replacement parts - a user manual would be great so I can get part numbers

Can anyone help please??

Many thanks

David

 

1980/89 Ford 600/900 Series Truck Parts Catalog available on a C/D from hipoparts.com

But, Ford truck parts catalogs are not EZ to use, so how much help you will get from it...is?

In order to post the pic of the rear brakes, I need to know exactly what your truck is.

Certification Label glued to the left door face below the latch: Post the VIN and AXLE code printed on it.

Also measure the width of the rear brake drum and if you have brake shoes, I need to know their diameter and width.

Where you will find brake parts in the UK for this truck...I don't know.

 

Hi - thanks for the reply !

I will be taking it all apart again in a couple of weeks time - so I will photograph and measure stuff.

The truck was never registered in this country so I don't have a VIN - so no exact date etc - not easy is it !!!!!

I will post some pics asap

Many thanks

David

 

You have the VIN because...it's printed on the Certification Label (see post #6 for its location). 1980 VIN has 11 digits, 1981 thru today VIN has 17 digits.

I also need the AXLE code. See example of Certification Label in pic:

 

Hi - yes - found the sticker!

VIN is 1FDRD84N7FVA63295

axle type is P

does that help ????

 

Is P the only AXLE code? It should be 3 digits, not 1. I need that code, otherwise we'll be up **** creek without a paddle!

1FD = FoMoCo USA - Ford Truck - Incomplete Vehicle.

R = Class 8 Hydraulic Brakes - 33,001-55000 lbs. GVWR

D84 = C800 Tilt Cab (diesel) without sleeper.

N = Detroit model DDN 990T 501 cid 8 Cylinder 8.2L Diesel.

7 = Check digit, FoMoCo use only.

F = 1985.

V = Kentucky Truck Assembly Plant.

A63295 = 1985 Numerical Sequence of Assembly, the trucks specific serial number.

 

I am trying to send a photo...

 

DSO: 543839

54 = Omaha Nebraska Ford District Sales Office, where the original selling dealer ordered the truck from.

3839 = Domestic Special Order number, truck ordered special by the original purchaser (it was not the USAF!), not "bought off the lot."

I suspected that when you said the AXLE code was P that this was a Domestic Special Order, because P only refers to the front axle.

But I didn't expect the DSO code to begin with 54. This truck was not sold to the US Gov't (USAF)...for two reasons. The DSO code is wrong, Gov't vehicle DSO's begin with 83.

It was painted 1B = Medium Charcoal Metallic. USAF trucks were painted dark blue and there would not be an exterior paint color code.

Missing first 2 digits of the AXLE code: The rear axle was not an RPO (Regular Production Order), the truck was sent out by FoMoCo after it left the assembly line to have a special rear axle installed.

You'll have to do some research to find out what it is. Meanwhile, back at the ranch...look on the brake drum for a series of numbers/letters and post what they are.

If the drums are original, they will have a Ford ID engineering number stamped on them.

 

sorry for the radio silence - we have been getting a car ready to race and time has been against us !

i shoul dbe taking the rear appart again in a few weeks - I will send some pics and see if i can fins any other id marks/numbers

in the meantime - thank you for this information, it is really useful and important and will make the difference between me getting the truck running and selling it - i really don't want to get rid of it !

many thanks

david

 

Well - progress!!

I managed to find an ID plate on the axle - it is an M220D - serial number 17283A with a long number underneath

MJAAB125 1 E5HS4005DARA

Does that mean anything to nyone please?/ !!

I am after brake parts for this axle - slave cylinders, shoes, and all of the springs/clips that are in the drum as mine were all removed

Any help would be gratefully received - I am in the UK so would have to order from somewhere willing to ship

Many thanks

David

 

OK do you have backing plates? And do you have the drums?

Measure the inside diameter of the drum and width of the friction surface.

NAPA heavy/medium may have all those parts, and there are other sources as well.

Any other info on the axle plate? None of those numbers produces anything via search.
