After warming-up the engine — the oil pan should be hot to touch — remove the oil pan plug and drain the oil into a suitable container. While this is going on, open the oil filter’s case by unscrewing the large bolt on top. On some filters this bolt is removable from the cover, but on others it isn’t, so don’t try to pull it out if it doesn’t want to come out. Then remove the cover. Oil shouldn’t pour out when you do this, but it’s wise to be prepared. If the cover is stuck, tap it gently upward with a wrench or small hammer. For a minimum of mess, don’t remove the filter element yet. Instead, get a coffee can or other container — one that’s obviously large enough to hold all the oil in the filter — remove the drain plug from the bottom of the filter case, and let the oil drain into the can. Wait awhile so most of the oil drains out of the element. Five minutes is usually sufficient.

There are two basic types of lighting systems found on most common U.S. military vehicles in the MV hobby. These are the WWII type (shown here) and the post-war, or M-series, systems. Although the systems themselves are similar, many of their components and switches are different.

There are two basic types of mechanical parking brake systems used on most vehicles with hydraulic service brakes, as well as on many vintage vehicles equipped with air brakes. The first type, shown here, uses a drum or disk on the transmission or the transfer case output. When the brake is applied it locks the drive shaft so the vehicle’s rear wheels can’t turn. This system is used on many common collector military vehicles, including most jeeps, Dodge WCs and M37s, Kaiser M715s, some early model HMMVWs, most deuce-and-a-halfs, five-ton trucks, and also on many larger vehicles and construction or material-handling equipment. This CCKW example uses an external contracting band type brake.

Motor vehicle transmissions may be divided into two basic types: manual and automatic. There are three basic types of manual transmissions: the sliding gear, the planetary, and the friction disk, though the sliding-gear type — such as this three-speed — is the most common today, and is what most people think of when manual transmissions are mentioned.

Bendix drive starters such as this Prestolite, (as well as many made by Autolite) were fitted to Willys MB and Ford GPW jeeps, the GTB Burma Jeep, as well as most International and Studebaker vehicles. Bendix drive starters also went in and out of fashion on CJ-2s, CJ-3As, CJ-3Bs, CJ-5s, and most Ford cars and trucks well into the 1960s.

Experience may be the best teacher, but it’s often a hard way to learn and requires being lucky enough to survive the mistakes you make. My first experience with air brakes was in a U7144T similar to this. My truck was a closed cab model. It had a Hercules RXC 529-CID gasoline engine, a five-speed non-syncro transmission with 5th gear overdrive, a two-speed transfer-case, and an early style air-brake system with a mechanical parking brake.

One of the most common reasons a parking brake won’t hold is that the mechanism that applies the brake — the handle or lever in the driver’s compartment, and/or its connecting linkage — is worn-out, broken, or out-of-adjustment.

The G-749 family of vehicles—including the M211 and its 6-wheel variant, the M135—were painstakingly designed and engineered by General Motors in the hope that these trucks would be a permanent replacement for the CCKWs of WWII. General Motors pointed out that the vehicle’s similarity to the CCKW would make the M211 easily maintainable and repairable for motor pool personnel who were already trained on the G-508 (CCKW) family of vehicles. Further simplifying maintenance, the M211’s transmission operated on engine oil (OE) rather than automatic transmission fluid (ATF).

During the post-WWII years, Reo entered into a competition between Reo, Studebaker, and General Motors to design a new 2-1/2 ton tactical truck to replace the U.S. military’s fleet of GMC CCKWs, I.H.C. M-5-6s, and Studebaker US6s. General Motors wanted to hang on to the deuce-and-a-half market, and even though the military seemed to favor Reo’s design—first called the M34 (shown here), then the M44 Series. While both the Reo and G.M. trucks were accepted for production, the Reo M35 and its six-wheeled variant, the M34 (shown here), with its more powerful Reo Gold Comet 331 cid. engine and five-speed manual transmission, proved to be more durable and dependable, probably due to its relative simplicity, and went on to become one the most successful military vehicles in the world.

Historic military vehicle hobbyists come in as many shapes, sizes and ages as the vehicles themselves. Many start out by purchasing smaller vehicles, such as a Jeep, M151 MUTT, or an M37. Many are satisfied with these small vehicles and enjoy a lifelong association. On the other hand, some folks start out with a Jeep and work their way up the scale.

Looseness or wear in a vehicle’s steering knuckles may often be discovered while performing a lube job – assuming you’re paying attention – but a more thorough inspection can be performed by jacking your vehicle’s front end off the ground by its bumper or frame so the axle hangs from its springs.

Distributors are the hearts of battery ignition systems. In many ways they’re like magnetos in that they have breaker points, a condenser (capacitor), and use a coil to boost the vehicle’s low voltage – 6, 12 or 24 – up to the 15,000 or 20,000 volts needed to fire the spark plugs, they just don’t generate their own power to do so, but use the vehicle’s battery instead. Like a magneto, a distributor is usually turned by the engine’s camshaft, which on a four-stroke engine rotates at half the engine’s crankshaft speed. And, like a magneto, a distributor must be “timed” so that it fires each spark plug in each cylinder in the correct order and at just the right moment to ignite the fuel and air mix and produce the most power in the most efficient way.

This hows all the components of a pre M-series ignition system. This is the system used on virtually all WWII U.S. military vehicles, such as MBs, GPWs, GTBs, WCs, G-506s, CCKWs, DUKWs, etc., including most heavy trucks and special vehicles of that period: Studebaker, I.H.C., the Weasel, and so forth (though some tanks and amphibians had magneto systems). Most of the time, the only difference between WWII military systems and their civilian counterparts is the military versions sometimes have “splash-proof” distributors. This splash-proofing is generally just a Bakelite shield that fits into the distributor underneath the rotor and protects the points and condenser from... well, splashes.

Engine oil doesn’t only break down and become dirty from use, it also gradually breaks down over time. And, in vehicles that aren’t driven much, or are not driven long distances so the engine never fully heats up, moisture forms in the crankcase. Moisture also forms in engines, axles and gearboxes simply because of temperature changes. Water not only dilutes engine oil, it also reacts with the oil to form acids that soften and eat away bearing material. Therefore, you should change the engine oil at fairly regular intervals whether or not the vehicle is driven a lot.

The cooling systems of most common HMVs have three basic parts: 1) A water jacket cast into the engine block that surrounds each cylinder with liquid. 2) A radiator where most of the heat from the water is transferred into the air as it flows through the radiator core. This air is either pulled or pushed by the engine’s fan at low speeds or when the vehicle is stationary. or is forced through when the vehicle is driving down the road. 3) A water pump, which is the heart of the cooling system. The pump circulates water through the engine block, where it picks up heat, and then pushes the hot water through the radiator tubes where the heat is transferred into the air. The cycle is completed when the cooled water—which has given up its heat to the air—is pulled back into the engine for another go-around.
