SCWE (Special Cold Weather Equipment) Maintenance Manual

New to me!

Is that location for the battery box normal on some versions of Ford? Based on Chevrolet cab 13s, I think that location would leave the passenger feeling cramped for space.

[Colin Alford]

The in-cab battery box and manually operated started are both features of the Special Cold Weather Equipment.

Thanks Colin, that makes sense

I removed one of these starter levers from a late model 1944 / 1945 Ford F60L a number of years ago. There was not much left of the truck but it was apparent that it was an original piece of equipment. The truck had been professionally converted to look less military after it was surplussed. Essentially they just "rounded" out the sheet metal and sloped the windshield forward. I believe the companies name was Taylor and the trucks were referred to as a "Taylor Special." A number of them were purchased by Ontario Hydro for use on power lines.

I can't imagine how hot the cab would have been with a firebox and chimney inside! But, the design was probably recognizable enough to the troops who had to use it.

Have now merged various threads on cold weather equipment to build up our common body of knowledge.

The big question is: how much difference was there between the cold weather equipment for Ford and Chevrolet CMPs?

Also see the thread Ford heating (cold weather equipment) which I may merge with this thread later.

There were some other modifications but I can't remember what they were.

See Question about Cab 12 Chevrolet FAT for some pictures of that small gas tank.

An article in Wheels & Tracks magazine issue no. 34 on Chevrolet Wreckers gives some info on Arcticized vs. Winterized equipment:

(...)
(c) BRKD-3, as (b) but with No. 13 cab and arcticized (to -40° F). Body 4G1 for Holmes W45CE, 4G2 for Gar Wood CA5P crane. These bodies, which differed only in detail, were a development from the 4D1 above, with certain improvements. The 4G2 had a jerrican and oil can carrier instead of the earlier type POW (petrol, oil, water) carrier.
(...)
(e) BRKD-5, as (d) but winterized (to -20° F) and improved winch cable fairleads front and rear, and revised rear towing hook mounting.

Arcticized equipment (to -40° F) was produced in 1942 to Specification OA99 and fitted to CMP vehicles supplied under Contracts S/M 2563, 64, 66-74 and 2613 and 19, and Specification OA111 for the USSR. It comprised special fuel primer (for starting only), engine oil predilutor, cab heaters, under-chassis heater, tyre chains and detail changes to ignition and brake system, lubricants, fuel pump, thermostat, etc.

Winterized equipment was to Specification OA199 and intended to facilitate operation at ambient temperatures down to -20° F.

Does anyone have access to Specifications OA99, OA111 and OA199?

Here are three photographs of a shroud and Evans Heating Unit from a cold weather test conducted at Camp Shilo during the winter of 1942-43.

Thanks Ed. This must be showing part of the Arcticized equipment, seeing the separate small gas tank and cab tarp which covered cab from the window level down as pointed out by Phil.

[Tony Smith]

The Chevrolet Major Assemblies Manual also shows that part of the Arcticized and Special Cold Weather Equipment was a different complete Rear Axle assembly, presumably fitted with modified Brakes that were less prone to freezing, or permit easier access to unfreeze frozen brakes.

Is there any mention of this in any of the supplementary manuals?

[Colin Alford]

Tony,

The difference between an axle “Used with Arcticized Equipment or Special Cold Weather Equipment” and an equivalent axle that is “Not used with Arcticized Equipment or Special Cold Weather Equipment” is limited to the wheel bearing lubricant.
