I do have a running ebay search for the bearings and races. Everyone that pops up is crazy expensive. From my numerous phone calls with different bearing houses I could not find a cross reference for a less expensive "overseas" bearing. Thanks for the tip on the FWA tractor axles Craig. My friend runs the local IH Case dealership so that will be my next adventure.

Have you tried ebay for your bearings ? If you have part numbers and cross reference numbers from other manufacturers, it is surprising what you can find, usually at a reasonable price.

Farm Tractor FWA Parts "May" Fit Your Coleman FDA (Front Drive Axle)

As background, many farm tractor manufactures tended to instead describe their special-order 4x4 tractors as having "FWA" (Front Wheel Assist), "MFWD" (Mechanical Front Wheel Drive), or similar such wording. Much less frequently, the term "AWD" (All Wheel Drive) is also encountered. 

    Search Tip
: Keep the "FWA" term in mind when actually searching for 4x4 tractor parts, shop manuals, and such. 

My emerging research has determined that while EMCO (Elwood Manufacturing Company) and other companies also provided FWA axles on occasion (especially early on), it appears that many farm tractors with FWA used the Coleman "Model-9" FDA (front drive axle), or perhaps very similar models that had many of the same or very similar internal components.

Confirmation pending, but it appears that the (red) International Harvester (IH) Farmall models "806, 1066, 1256, 1456, 1566," and perhaps other models, all used a Coleman "Model-9" axle, or very similar modifications. The (yellow) IH model "2806" AWD utility/construction tractor also appears to have used a Coleman "Model-9." Does anyone know of additional IH tractor "FWA" or "AWD" models with Coleman FDAs?

Example IH Farmall Turbo 1206 with a Coleman FDA (Front Drive Axle) 

Similarly, the Massey-Ferguson model "97," and Minneapolis-Moline models "G706" and "G708" all seemed to use the Coleman Model-9 (or variations thereof) as a special-order option, after first experimenting with EMCO axles. There may have been additional MF or MM models with FWA also. Does anyone know of any?

I have already determined that Case, Oliver, Cockshutt, and perhaps others, also used special-order Coleman FDAs, but I have not yet determined the model numbers for either the tractors or the axles. Can anyone help with additional information?

While the following post is very old, it offers some tantalizing details:

Re: American Coleman 4x4 axle in reply to lex, 12-17-2008 11:21:47
I just received my parts to overhaul this front end on a 706 [editor's comment: Minneapolis-Moline "G706"]. The wheel bearings , races and boots came from Case-IH Part #271841R91 bearing $107.13 ea.; #879079R1 cup or race $59.00 ea.; #389050R1 Boot $122.25 ea.
- - -

While I have not yet confirmed that a "Case-IH Part #271841R91 bearing" will actually fit a Coleman Model-9 axle, this is an excellent example of possible ideas to pursue, of course first confirming the "needed" ID, OD and Width during your inquiry process.

>>> The take-away:  Farm Tractor FWA replacement parts suppliers (both current and historic NOS) just may be a possible source of less-expensive parts for your Coleman FDA.

I didn't mean to come across like I was at a loss for wheel bearing numbers. What I meant was reasonably priced wheel bearings. My Coleman kit Ford uses Timken 73562 bearings and Timken 73875 races. Apparently Timken is no longer making them and the ones on the shelf are BIG money. $500 for one race and $2000 plus for 1 roller bearing. I'm looking at 10k-12k just for wheel bearings. That is why I asked the question. Type it into google and it will blow you away.....I promise.
On a side note they are huge. 5 5/8 ID and over 8 inch OD on the race. Iirc one bearing is rated at 10k load.......x4= a little over built!

Coleman Proprietary Parts – What Made a Coleman a Coleman?

The question comes up from time to time, as mentioned in the previous postings, "Where Can I Find Coleman Wheel Bearings" and such.

Historically, there have always been essentially two types of truck builders: 1) those who built their trucks from the ground up, using primarily parts or assemblies they had been manufactured themselves (example, Mack Trucks), and 2), those companies who began with their own patented proprietary parts or assemblies, then built a truck around that using open source vendors for all other needed parts and assemblies to finish the truck.
  • Coleman always fell in this latter category, using their own patented or propriety components as a basis, then building a truck or aircraft towing tractor around that, using open source vendors. 
  • While there are several other notable exceptions, the primary assemblies that made a "Coleman a Coleman" were the "steerable Coleman FDA" (front drive axle) and the "Coleman Transfer Case." Some G-55 and EH-62 trucks did have a somewhat unique rear axle assembly, and of course the G-40 (MB-4) and G-75 (U-18) simply had steerable Coleman FDAs on both front and rear. 
  • The purely "Coleman" sub-assemblies in the Coleman FDA were the axle-housing casting, the hub-housing castings, the patented "power yoke and compensating ring," the hub itself, the heavy dome hub protector, and several lessor fittings and adapters. The axle "shaft" itself was always Wisconsin (later bought out by Timken), and the bearings, etc, were largely open source. Not sure about the steering knuckles. 
  • The same is true of the "Coleman Transfer Case" (and housing) – always based largely on Spicer parts, then later Dana Corporation, as on the EH-62. Coleman designed their own transfer cases, but using many Spicer components and sub-assemblies in the process. 

So, bottom line, unless you need an actual Coleman power yoke, compensating ring, or other Coleman-specific castings and such, many parts (but not all) can be found from open-source vendors. They may have been assigned a Coleman part number for inventory and assembly line purposes, but they were often "right off some vendor's shelf," and supplied to meet very exacting Coleman specs.

>>> As an additional after-thought, International Harvester (IH) used large numbers of special-order Coleman FDAs on their heavy truck and Farmall tractor assembly lines, and while IH assigned their own IH front drive axle model numbers (such as the FA-140) on their catalog pages and such, they were all "most likely" Coleman "Model-9" FDAs, and even if slightly modified for IH use, they may have used many of the same internal components, such as the wheel bearings.  While IH preferred to use a "cake pan" style hub-protector on their trucks, internally, the hub components were perhaps virtually the same.  Conversely, IH Farmall tractors tended to instead use the standard "Coleman" heavy dome hub protectors.  You might want to try IH distributors, or distributors of historic IH parts, to see if you can match the needed specs for wheel bearings and such.

Mark, I would assume the wheel bearings aren't anything special. There are probably bearing manufacture numbers on them, not Coleman numbers and should be easy to source at a power transition supplier (bearing store).  If there are no numbers on them they can be identified by ID, OD and width.

Ya know what they say about assuming things.
EDIT: similar to 55 and 56

Craig, we plan to be at the show on Saturday. I will try to find you. We plan to check out as many vendors as we can and then check out the trucks. As we have never been to a AHTS show it will be a learning experience. I am also going to try and pm you with my cell number if you want to try and call me Saturday to meet up. 

Another thing that had me thinking when I see these Coleman tugs is the front wheel bearings. The hubs look identical to my Coleman "kit" Ford F4. So I wonder if anyone has every had any luck sourcing reasonable front wheel bearings? I assume tugs travel MUCH slower and have fewer miles than a truck would have so maybe the wheel bearings have held up better on tugs? 

If anyone has found the giant wheel bearings for a Coleman please let me know. Thanks...............Mark

Hi, thanks for the reply! 561137 is the serial number but unfortunately I could not find a data plate on the transfer case.


Based on the serial number you provided, it appears that you have a the chassis for an "American Coleman G-40-B2" manufactured in Littleton, Colorado sometime in 1961.

Photo of American Coleman G-40-B1 serial number #5600064 built in Jan 1960.  Your "B2" built in 1961
would have looked virtually identical.  A later owner added the snow plow lift frame in front.

  • To clarify, American Coleman developed its G-40 prototype in 1954, in response to a USAF "call for bids" to satisfy requirements ("specs") for the their newly-created "MB-4" classification for smaller aircraft towing tractors better suited for lighter fighters and bombers then coming on the scene. 
  • Over the years from 1954-1981, the G-40 went through (8) major variants (A though H), while very minor modifications would simply be noted with a numerical suffix within that particular variant. Hence, your G-40-B2 was a minor modification of the "B" variant, but not yet significantly different enough to justify a "new" variant. Variants A-F all looked very similar, but then variants G & H had a newly-designed cab, with a hood that could be tilted forward for easier maintenance.  
  • Also, while all American Coleman G-40s were classified as USAF "MB-4s," other manufactures also won MB-4 contracts (same operational specs, but very different appearances), to include Grove, Entwistle, NMC-Wollard, PSI, Dodge "bob tails," and perhaps others.
