My truck has a slow air leak I'd like to patch up and I would like to find it (or them, plural?) the easiest way possible. It seems to lose about 30psi per day, or if I park it after a drive, the tanks will drain after about 3-4 days. I was thinking about making some kind of fog machine hookup...

A few months ago I replaced the injection pump on my 923. At first, everything was running great. Then, after about an hour of the engine running, it died. It would always run just fine if the engine was cold, or I had some time in between cranking the starter. Thus began a multi-month...

Between my DMs and a couple responses on other threads, I figured I'd consolidate everything into one thread. I replaced the fat old injection pump this last weekend and got everything working great. I know there's plenty of wisdom and experience in these threads but I wanted to share a couple...

Just got my Baldwin 1368 in the mail, for converting the oil filter to a spin on type. Instructions say to use a specific included gasket only if the motor has a "NH Horizontal Pump Mount Head P/N 197093". Does that apply to the NHC 250? I can't find anything online or from previous oil filter...

Hey all, Bad news. I took my truck to a welder shop to get a trailer hitch receiver put on, as I do not trust the quality of my own welds. I showed them where to disconnect the batteries and where to disconnect the ground strap from the PCB, but alas, the welders did not remove the ground wire...

Howdy guys. I'm active duty Air Force and the time is approaching for me to move bases. I'm anticipating roughly 1,200 miles to my new base and am currently planning on driving my 923 the whole way. The truck overall is in really good shape mechanically, to the point where I'm actually planning...

Hi all, I got a little bit of spending money and I think I want to attack replacing the injection pump on my 923 A1. It currently works, it just leaks some diesel from old gaskets (only when running) and the internal part where the tachometer cable threads into is broken so I don't have a...

Hey all My truck wouldn't start the other day. The starter motor made no clicking sound or anything which I thought was strange. I then noticed that turning the battery lever off does NOT turn off power to the truck, as in, the gauges stay powered, the buzzer still buzzes with the ignition in...

Hi all, Long story short, I'm getting a really good deal one of those Harbor Freight 12k Badland winches (this guy) and I want to be able to use it on my 5-ton. All the documentation only mentions running on 12 volts. I know *technically* those simple electric motors work with a range of...

Hi all, This last weekend I was replacing my tach cable / cable adapter trying to get my tachometer working again. Unfortunately, once I got the cable out from the engine (where it threads into the injection pump housing, by the mate to the air compressor) I noticed the old tach adapter...

Hey all! Noob poster here, so I apologize for noob-ness in advance :) Just picked up my new-to-me M923 A1 this last weekend and love it. I've been reading the TMs and familiarizing myself with everything this last week and have a question about hydraulics. The TMs make it seem like only the...
