The first recommendation is to wash the undercarriage and especially around the backing plates, this is where a pressure washer or a steam cleaner comes in handy. It gets down right annoying to have dirt falling on your clean parts, on your face and in the eyes when working. After the truck is...

The M332 trailer has two air lines; one is the service line (yellow or blue) the other is the emergency (red) line. The air lines on these trailers as well as the 105’s, 103’s and MKT’s etc. is just standard air line that is used for over the road trucks. It is available at most places that sell...

This is the bearing packer that I use. It is made by Lincoln.

Just something to consider when going to Ft. Meade. Even though they aren’t quite as uptight about taking pictures as Aberdeen, the NSA people are next door.

The way I have done them is to remove the bolts that hold the floor pan in, and then lift the pan over the shifter. Leave the shifter in place. Then while in the cab remove the upper bell housing bolts. Remove the sixteen bolts from the jack shaft, that’s the shaft that connects the...

That certainly sounds like a throw out bearing to me also. Unfortunately the bearing can not be greased and since the truck(s) sit so long/ are some what old the bearings tend to dry out. The good news is that if one has a good sized transmission jack it only takes about two hours to replace...

The 818 has a few things going for it and a few things against. The NHC-250 is a very reliable but underpowered engine. Besides the obvious things like oil pressure, leaks and what not is to check the oil for milkyness. The 250 uses O rings to seal the liners in the block. If they are...

As already posted there should be zero current draw when the master switch is off. If there is a slight draw more likely than not one of the diodes in the regulator is going bad. The alternator will still charge with a bad diode; however it won’t be long before the regulator will have to be...

I’ll have two complete M59 field ranges and some NOS immersion heaters. If anyone is interested in some camo support pole kits, not the screens, PM before 10am Wednesday and I’ll load them in the trailer.

There is no one answer to the question. As already stated it depends on what you are striving for. Every tire and every setup has plusses and minuses. I think one of the biggest reasons the military has gone to the single tire is for the central tire inflation system. It is easier to control...

Where to start? First off there shouldn’t have been a “lot of pressure” when removing the filler plug. The vent(s) is probably clogged and should be cleaned. A temperature of 155 degrees is normal. If you have a PTO check for lash as already posted. I would start be changing the fluid in the...

The nuts that hold the jack shaft bolts are notorious for coming loose. Any good quality grade 8 bolt and nut will work, however the “correct” nut will be a FLEXLOC nut by SPS fasteners. The FLEXLOC nut is designed to be used several times. When there is no longer resistance when tightening them...

I wish I had seen this earlier but I was out of town. I could have brought my 197 over with some tools and probably gotten that out for you with a lot less headache. You mentioned the wrecker service had to cage the brakes. That trailer may have a jostling valve on the left side of the frame...

First off I don’t have any pictures so please no anyone ask. I would use “wedges” to break the beads. They are made with 4”X 4” angle iron 5/16” thick cut 4” long, and then bent from a 90 degree angle to around 110 degrees. Make three of them and one can break down just about any wheel. Place...

It sounds to me like the parking brake is sticking. I would check/ lube the parking brake cable first. Then lube the pivot points for the parking brake shoe. There should be a mustache shaped spring that pushes the shoe away from the drum present. If it is missing I would recommend...

Obviously no one likes to fix a flat tire on the road, or anyplace for that matter. However some times one has no choice. If I have a flat on a rear, assuming duals, I run it till I get home or where I’m going. Very few people load their trucks with enough weight to worry about overloading the...

I’d like to make some of these shindigs also. In case anyone didn’t already know there is a gun show the weekend of the 21st and 22nd at the Equestrian Center in Upper Marlboro. I’m committed to be at the show both days, and with how sales are going lately it may prove to be a busy show.
