Here is the link to the MB-C2 (W)Supplement To Maintenance Manual MB-C2 Covering Special Cold Weather Equipment. http://www.canadianmilitarypattern.c...0Equipment.htm if you click on the image of each page you will see a High Resolution version of the page.

I think this will answer your question about the location of the oil filter in the later Pattern 13 Chevys. Standing the filter unit up right made servicing easier and allowed for a drain tap to drain water condensation out.

Hi All

I've fixed the problem with Hi Resolution images of the last three pages.

http://www.canadianmilitarypattern.c...0Equipment.htm

This Supplement Covers the following:

• Cab Heater and Defosters
• Engine Primer System
• Crankcase Pre-Diluter
• Modified Standard Equipment
• Miscellaneous
• Lubrication

It helps to explain some of the running changes on Pattern 13 Chevys such as change of oil filter location and size. Those three little pipe plugs on some intake manifolds.

Now does anybody have the supplement for the Arctic modifications, it includes the addition of a separate small gas tank, a cab tarp which covered cab from the window level down and a gasoline space heater that was put on the ground under engine, the tarp of course was to trapped the heat in. There were some other modifications but I can't remember what they were.

Also does anybody have the Ford Cold and Arctic Weather supplements.

If you are wondering about the condition of my copy, it apparently lived in the tool box of my HUP from 1945-1979 along with a full set of manuals for the HUP.

Cheers Phil

Hi guys.

Found this old thread and thought I'd post some pictures of the arctic kit on my CMP. I has primer pump, diluter, personell heaters.

A nice detail is the production month/year markings on the electrical motors.

Here are som pics of the insides of personell heaters.

I will post more pictures later.

Hi Svenn

Do you have the little one way valves for the primer pump? I may have just seen a source for them the other day.

Cheers Phil

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?
