If you are putting an RT1439 in your truck, you must use the 6352 mount. The 1032 while similar, will not work because the AM-7239 will not attach to it. My A3 came from GL with the sugar scoop, the 6352 mount and the LS671 speaker installed and wired. All they did was remove the AS-3900...

Contact Mike Murphy at Murphy's surplus. He has the mounts, cables, radios, antennas, etc. He has an elaborate web page, but email him because he has tons more that isn't on the page. If you are ever in the San Diego area, it is a real candy store to browse. Mike is a square deal guy he knows...

I replaced original (broken) stock with NOS Norgren regulator in GI packaging. It had NSN. I added schrader valve to gauge port for setting secondary side pressure. other than that, dead stock.

The stock reg is jet black and has a cylindrical metal cover that threads over the whole body. You have to unscrew that cover and slide off to gain access to the press adj knob. The two units I've seen fail were leaking from the adj knob area. My prior thread post has pix so you can Id it. The...

I've used WD40 to clean dirty/greasy CARC radio cases, etc. It really works nice. Not sure if it works for oil or axle grease

I agree regarding adjusting the reg. I replaced mine with the original NOS Norgren from fleabay and found there was no way to measure the pressure, so I rigged a schrader valve. I have a thread posted with pictures describing it.

I did the oil bit 3 times and noticed that after time 1 & 2 a big improvement in how the air-o-matic system worked. That is the Sycon trade name. They still sell & repair this system - at least they did in December when I was looking for answers like you are now. The oil stopped a slow leak...

The converging hoses are the exhaust hoses. The intake is a single hose and there are two hoses to the ram itself - 4 hoses total. The load sensor may have a sticking point where it leaks across from intake to exhaust. MAny members have been successful pouring a little Marvel Mystery oil or...

My A3 came from GL with the sugar scoop, the 6352 mount and the LS671 speaker installed and wired. All they did was remove the AS-3900 antenna base and the actual SINCGARS radios, which I have now replaced. The sugar scoop is mounted on a small piece of pole that is U-bolted to the bed midway...

For a great radio that is true us mil try the prc-104. It is available in a or b version. It is a transceiver with built in tuner and is mountable in vehicle or on backpack. It was built by Hughes and the b version is current issue. It is available as a go kit with Alice pack and all the...

Air tool lube oil or Marvel Mystery Oil works wonders on the steering control valve. The internal parts can seize with rust/crud due to moisture in the compressed air. Disconnect the air source and pour some in then work the steering wheel back and forth to cycle the valve. It may take a few...

After the compressor belt, the second thing I'd look at is the water pump. That often dies with an awful sound and the belt screeches when the pump seizes. After it bit it may start to spin. I almost scrapped an engine because I thought it was a main bearing. I cut the belts one by one as a...

My experience & research is exactly the same as above. The 545 and 1545 will work with 10w40 oil, but it is not recommended. If MO is used, the performance is lower and the service life is much shorter. The only fleet that uses MO in these trannies is our rich uncle sugar who can afford to...

The A3 does not need max power to SHIFT into reverse. The other posts were about the truck bogging down.

For a recovery, make sure you take a bunch 'o DOT-5 brake fluid. Don't use anything else! Empty, that truck is 14000 lbs and really, it doesn't matter if it goes slow, gets poorer fuel mileage, implodes the tranny, etc. compared to not stopping and plowing through other cars at an...

6K & 3 Needs a B. That simple. The law is clear and the English is simple. No exceptions. Intent doesn't count for s**t. The road to **** is paved with 'good' intentions.

Welcome to the innocuous and evil 'sprag' gear. It was superseded by the air-engage in late models. I've heard many horror stories about mr. sprag

I have overhauled the air dryer system on my truck and entirely rebuilt it. It is a very simple system. The purge command comes directly from the compressor governor via a small airline from the governor (not the air line to the storage tank). When the compressor unloads, the dryer purges by...

And please show him the courtesy and respect for his services by making some donation as requested to the wounded warrior foundation he indicates on behalf of the SS site. Consider it as a token of appreciation for his time and dedication to our hobby (not to mention the sacrifice that our...

I switched to Napa NHF 85-405 Premium Heavy Duty Tractor Hydraulic & Transmission Fluid GL-4. This fluid (in 5 Gal pail also) carries GM Dex-III, Allison C-4 and Caterpillar ATF ratings. It is cost effective and made a world of difference in my truck, both in shift performance and in much...
