I used a very large pry bar and it came over it very easily on all the tires. I did pour tire lube over the area before prying, however. No damage to any tires. I was very lucky in that I inherited a lot of truck tire changing tools from my Grandfather that date back to the 1930s. Very handy...

If you are careful there is minimal risk of damaging anything doing the dismount with tractor forks. I've done several tires this way and not had any problems.

Was it motor oil or ATF? When ATF is burned, or dark brown in color, its a bad sign for transmission health. It normally means that clutches have been slipping. Whatever else you do, you need to make absolutely certain that the transmission is purged completely of motor oil if you switch to...

The behavior you outlined is typical when motor oil is still in the transmission. Especially downshifting when slowing down or stopping. Switching to Dexron III eliminated this in my A3.

I'm keeping the CTIS on my truck. It works quite well, but I don't use it, I just leave it turned off. I run 60 PSI in my 14.5 X 20 tires and the truck runs much smoother with the higher pressure and I suspect my tires will last longer. I had to rebuild one hub when I first got the truck...

I'm still using the CTIS, so I think I still need the original valve stems. I just used my last spare one as a replacement for a very corroded one on a leaking tire/wheel. I still have two tires that leak down over two weeks and I don't want to tear them down unless I'm prepared for the worst...

I recently replaced my steel hood with an NOS fiberglass hood. What a difference! The fiberglass hood looks substantially better and is much lighter when raising and lowering. I don't have insulation on the fiberglass hood, but I can't tell any difference in noise levels from when the steel...

I need some parts for my A3, if anyone knows a source. 1. Heater control cable 2. Wheel valve stems 3. Passenger side mirror rack

Please refer to the attached document, put out by Allison and which covers the 1545 transmission. It lists fluids authorized for the transmission. Dexron III covers a larger range of operating temperatures. Another thought is how many 1545 transmissions have been produced, and most are in...

I switched to Dexron III several years ago. What a difference! Shifts up and down much smoother. I didn't contact an Allison dealer, I contacted Allison directly and talked with an engineer in their Technical Support Dept. I had a difficult time getting to one of their engineers since they...

Sounds like someone was trying to prevent people from using the winch or perhaps there was an air leak they were trying to bypass.

Congratulations! That was a relatively easy fix :beer:

I don't think rebuild kits are available for the cylinder. Are you sure yours needs rebuilding? If you have a problem with seals, many folks solve their problem by adding a small amount of air tool oil. Adding the oil solved all of my problems. Add the oil at the inlet port of the actuator -...

Make sure that whatever coolant you use it's the heavy duty ethylene glycol type. Also, if you don't use premix, make sure you use distilled water for the dillution to eliminate phosphate buildup in the coolant system. It will take a lot of distilled water jugs, but it is definitely worth it...

Welcome to Steel Soldiers! You've come to the right place. The first thing I would recommend is to read the TMs. Specifically, look at the electrical schematic. The wiring on these trucks is relatively simple and your problem should be simple to figure out. However, your most critical...

The problem with speed in the A3 is the CAT 3116 engine. Continuous operations with the stock 14.5 R20 tires limits the top speed to about 45 mph, whereas the A2 will do 55 with the 900 X 20 NDTs. The Allison 1545 transmission was designed to use Dexron III transmission fluid. The military used...

Welcome to the site. You have a nice looking truck there. You'll have a lot of fun with it. Keep us posted on what you do with it. Looks like you need a new headlight though. For some reason, my A3 loses headlight bulbs regularly. They don't seem to last nearly as long as on my A2, which...

Replacing the fuel filter is straightforward. You will likely need to rod out the drain cock on the bottom as they tend to fill up with crud. I rod mine out, open it and then crank over the engine to let clean diesel flow out. The check valve that plugs up first is located at the elbow where...

My A3 always starts easily, less than one revolution by the starter unless the temperature is very cold. I would first change the fuel filter and clean the check valves before proceeding further if you haven't already done so. These CAT 3116 engines start and run well.

I don't know where you can buy a replacement, but are you sure it's bad? The check valve is a simple device and I was able to clean mine and make it look like new, although it took about 30 minutes of picking out the crud.
