You have already discovered the key to survival in military transportation ops: get the pubs and read the reading and lubricate everything. On M35s the most troublesome drive shaft in terms of u-joint failures and loose flange bolts is the one between the transmission and the transfer case. The...

Another form of night driving rarely practiced was to use infra red (IR) devices. Clip on lenses that fit over wheeled vehicle headlights were used on wheeled vehicles. Tanks, APCs, howitzers and other tracked vehicles have built in IR lights. A vision device would be used by the driver and...

It has not escaped notice that a lot of "fuzzy" information gets out on this site based on what someone thinks someone else thought about the subject at hand.@ Doyle's comment in post 18 is plausible: a "one off" unit could be built to test something, but there is no hard info on this as to when...

Hope we can hear from Doyle on what he has on rebuilding M39s into 809 series. Pictures, Production numbers ? I imagine production would be limited. On the face of it it appears to be an inefficient way to do business but that wouldn't bother the Army . A prototype to test the concept ? The...

Successful B.O. driving requires control of the total environment, something that the average Army Brigade or Corps Command does not supply. In WW2 with the Red Ball Express a movement control system was put in place to regulate movement such as might be found on a railroad. Parallel roads were...

I have seen M 54s and M35s upgraded to A1 and A 2 status. I have seen M35A2s made into A 3s. I have seen the steering gear from wrecked 809 series trucks transplanted to M62s. But I have never seen a M39 series truck like an M 54 turned into an 809 because as mentioned in post 10, the frame and...

Don't make a move without the pubs: operators' manual, organizational manual and parts book, and a lubrication order. The TM numbers are typically found on a data plate on the right side of the dashboard. There are many more grease points on a military hummer than a civilian one. Neglect them...

Get or download the operators and organizational maintenance pubs and a lubrication order. Lubricate everything. Check all fluid levels. Have extra make up coolant, motor oil, transmission oil, glass cleaner and the necessary tools to open the relevant gear cases to check/fill.

From the description in post 1, parking brake released and service brake not applied, there is a leak in the emergency side of the dual brake chamber. Opening these up at home is hazardous to your health when what is left of the spring comes out and bites you. It is safer and more practical in...

Reference post 13: ya gotta lube it with something. The 6 grease fittings refer to 2ea for each trunnion and 2ea for the jaw. A 7th fitting is provided to lube the top of the plate when there is a trailer coupled to it. The Army uses GAA for this as they are not sophisticated enough to use...

Blackout driving is a fantasy that the Army has clung to since WW2 when the target acquisition capabilities of the OPFOR air force were limited to the pilots vision. They are designed to be invisible from any height above 90' but visible horizontally for considerable distances. The "Wheeled...

Reference again to post 3: If you need to introduce air into the dead horse as described through a drain in one of the air tanks, preferably the one closest to the compressor, you will need a fitting as illustrated to replace the drain valve in the tank. Then use a tire chuck to fill the tank...

Reference is made to post 6: the trucks in question were issued to the unit in the spring of 1988 and had been shipped directly from the AM General point of manufacture, South Bend IN I think. At this distance in time I do not know if they had been held at the factory before being issued but I...

Reference post 3: the emergency glad hand will release the emergency brake, but won't the air in the reservoir then be available to operate the service brake (until the air is used up ) ? Or hook both air lines up to another truck and use the brake circuit in that truck to operate the dead...

The size of the spare tire carrier raises a question but the unit I was in at the time received brand new M923s with the same tires as this truck and also without a CTIS. At the same time other units got them with 1100:20s. The CTIS version appeared a couple of years later.

Assuming he has a way to ramp the load off the trailer and down to the ground he will have to "pin" or cage the parking brakes on the rear wheels to release the parking brake unless he has some way to air the truck up and release the brakes with air pressure. This will also render the service...

Reference post 2: some form of working brake is required if the trailer is RATED for over 3000#. That is why your trailer has surge brakes so you will be in compliance. Various uninformed minds on this site think if it weighs less than 3000# empty brakes are not required. Wrong. There is a...

Get and READ the pubs: operators' manual, organizational manual and parts book, and a lubrication order. That is TM 9-2320-260- 10, 20, 20P, LO. There are about 50 grease points on a tractor, 4 on the handbrake alone. Neglect them at your own peril. Know how the fuel transfer valve works and...

If you but the truck get the pubs: operators' manual, organizational maintenance manual and parts book, lubrication order. Find out what "caged the brakes" means. How to operate a GI light switch and such. Where to get 24 volt lights an d so on.

Big trucks usually don't command the value of Jeeps because fewer people have the space to store one or the tools and inclination to maintain one. I recently bought a M818WOW and a companion M871A2 trailer for about half of what a lot of people ask for a reasonably turned out jeep.
