Do yourself a favor and read the reading. Don't make a move without the pubs: operators manual, organizational maintenance manual, parts book and lubrication order. All of these are available on this site for the vehicles you are interested in. Grease is cheap. Parts cost money. Be guided...

The recording speedometer/tachometer described in post 14 requires the appropriate dashboard/instrument panel to fit it as it is bigger than the separate instruments found in cargo trucks and such. Recording speedometers are unique to 818 tractors issued to line haul units which kept track of...

If you have not disturbed the lug nuts on your truck lately they are likely in the grip of much rust and paint. If you happen to have a 1" impact wrench they will likely come off. However the issue tools in the vehicle's OVM probably will not be adequate. Remember the hardware on the driver's...

If it is the engine side noise could be coming from governor which is mounted on the firewall. If on interior side check low air alarm pressure switch. Air leaks can be detected with windex or soapy water which will blow bubbles in presence of air leak. Just for giggles, is the power take off...

Reference post 46: compressed air is a means of storing and moving energy. A M816 has an engine driven air compressor, a governor to control it, a reservoir to store air which must be drained after use to expel moisture, valves to control the windshield wipers, pressure switches for the low air...

The wires are identified with metal clips with the circuit numbers embossed on them. On any vehicle that has the same circuit it will be identified with the same number. A the lighting is essentially the same except for the length of the wires you can refer to almost any circuit diagram to...

NSN for fan belts appears to be 3030-01-118-1318.

The parts book for the 939 series truck is available on this site. You can look it up yourself which will yield a NSN which most auto parts stores can translate into a Gates or whatever number.

When I did mine I bought a new wiring harness and specified Packard plugs for all lights as the composite lights have Packard plugs. Stock there is one wire for the BO brake light which is mounted on the right rear part of the chassis. As you now have 2 BO brake lights you will have to rig a...

The multifuel engine is supposed to have the fuel delivered to it under pressure. An electric transfer pump in the fuel tank is provided for this purpose. Does the pump run when the battery switch is turned on ? If there are vacuum leaks in the fuel line between the pump and the engine it will...

Reference post 37: from top to bottom: service taillight. 2 bulbs, smaller one is for tail light, larger 2 filament bulb is stoplight/turn signal. Army uses the turn signal circuit in tandem to operate brake lights. Unlike a commercial truck, there is no separate brake light circuit. Next is...

I hope you have also been reading the applicable TMs which are available on this site. Don't make a move without the pubs: operators' manual, organizational maintenance manual, parts book and lubrication order. Parts cost money, grease is cheap. There are over 40 grease points on a M35A2, 4 on...

Reference post 31: If you cannot get all the lights to work by pushing the various buttons on the switch you need a new light switch. Get one with the levers, it is a direct interchange. I think the center button on the push button switch turns it on, then push the button for the lights you...

Lights: All tactical vehicles have two independent lighting systems controlled by one switch so only one can be used at any time. The small lights at the bottom of the composite light are black out marker lights. There are two white lights on the front lamps and four red lights on the rear...

Post 20: the pictured light switch was a replacement geniuses in TACOM dreamed up to replace the original lever operated switch. One drawback was you had to see it to figure out where it was set or change it. It was also somewhat unreliable and I am informed several electrical fires were...

The applicable TMs for a M 816 are: TM9-2320-260- 10, operators manual, -20 organizational maintenance manual, -20P organizational parts book, -20LO - lubrication order. There are almost 100 grease points on a M816; neglect them at your own peril. 4 on the handbrake alone. As post 2 suggests...

Reference post 12: Read the reading it will serve you well.

Reference post 15: Baffled yes but transverse baffles that restrict movement front to back, NOT side to side which is why they roll over easily. Yes, check for a DOT data plate on the tank itself some[lace. The Army buys semi-trailer tankers that together with the tractor run on 5 axles and...

4000 gallons really ? That is like 33,000 pounds of water on 3 axles ? How are you planning to get it to stop ? This is almost tractor trailer loads and they have five axles to your three.
