    Self recovery with one person, one pickup, and one M939- how to do it?

    Not really an option. My bumper is welded to the frame but it's also cost prohibitive to change it out. After thinking about it last night, I might be able to borrow 98G's design but I won't know for sure until I get home next week from my travel. Will let all know what I find out.

    Self recovery with one person, one pickup, and one M939- how to do it?

    Those are nice brackets. Simple yet effective. Unfortunately I don't think I have such a simple fix for my front bumper. I do have two tow hooks (loops) I could shackle up to the tow bar but they are at odd angles and will have a lot of slop in them. While using shackles will be effective...

    Self recovery with one person, one pickup, and one M939- how to do it?

    I never thought about using a military tow bar to flat tow my truck as I was stuck on using a trailer or such instead. But that is a good idea. I'll have to think a bit on how to attach my tow bar to my 1-ton Ford with a Ranch Hand replacement front bumper but I think I can make something...

    Self recovery with one person, one pickup, and one M939- how to do it?

    Here's the scenario: Pick your flavor of M939 series truck with a NHC250 is located 200 miles away. Seller says truck runs, tires are good, and license tags just ran out last month. The only issue is it's hard to start and dies at idle if you don't keep the rpms up (sounds like air leaks in...

    True failure rates of the 6CTA8.3L injector pump?

    I hear ya, CSM, and agree with what you're saying. I was really hoping to self-recover the truck as it's parked in an area behind a barn. The owner said I'd need to arrange it to be towed out as a typical RGN truck/trailer wouldn't make it to the truck. So you're right I shouldn't fix another...

    Reusable hydraulic fittings on wreckers

    @Jbulach I just saw your post #8. That is a very interesting observation about the mix/match of reusable vs. crimped hydraulic lines. My only guess would be the Army viewed the crane as dangerous if a fitting failed so they went with all crimped on the crane system to eliminate...

    Reusable hydraulic fittings on wreckers

    Good catch on the first link being for non-wrecker stuff. On the second link, post #8 Wes says "those hoses have reusable fittings on it as designed from the military so you don't have to have ends crimped on. Just simply replace the hose." Wes is pretty accurate so I'm reading it as the...

    Cummins NHC 250 versus Cummins 6CTA8.3

    Nice collection and a beautiful background. Looking at 98G's wrecker makes think of something I've noticed a lot lately. And that's a lot of wreckers I've seen for sale don't have the vise on the front anymore. I'm guessing the vises are being taken off and sold separately or kept as a useful...

    Reusable hydraulic fittings on wreckers

    Yes- thank you. A quick google showed those are the style of reusable fittings I'm used to seeing around. They have the flats for a wrench where the crimp would be. I tried to download a pic of them to show here but the format wasn't correct for an upload. But with all the discussion on...

    The curious case of the M923A2 Shut Off Solenoid.

    I've never liked harness grounds, engine grounds, or other frame grounds for critical circuits. IMHO, if there is a item like the FSOV that requires uninterrupted, full voltage/power for the vehicle to operate, then that circuit should be grounded directly to the same spot where the negative...

    M818 no crank

    I'd double check battery connections, battery condition, and grounds and then have someone hit the start lever when you're checking voltage at the starter. Many years ago, I chased the similar problem on a mid-70's (told you it was many years ago) Honda CB550 motorcycle my uncle gave me to get...

    Reusable hydraulic fittings on wreckers

    I read a lot on SS that 5-ton wreckers (M936s for sure and maybe M816s) came with field repairable or reusable hydraulic fittings. But when I look on pics of M936s for sale, I don't see the kind of reusable fittings I'm used to seeing that have wrench flats where the crimp would be. I found a...

    Cummins NHC 250 versus Cummins 6CTA8.3

    If Nice on the M920. I think that's the Cummins Big Cam tied to a Cat 16 speed tranny, right? If so, lower your power expectations quite a bit with either the NHC250 or 8.3L Cummins. But since you have experience with MVs and know what you're looking for, I say you'll do alright regardless...

    M936A1 crane ops- basic questions for engaging transfer case PTO

    Thanks guys- appreciate it. I'll let you know what I find out. Wreckers are a new one for me so it will be a bit of learning curve when I get on it.

    Cummins NHC 250 versus Cummins 6CTA8.3

    What do you want to do with it? You live in the mountains or sea-level flatlands? If hobby use, then put the money towards the best wrecker you can afford as a hobby. Wreckers are dirty, nasty things that have a lot of issues compared to a regular truck. When you buy a wrecker, you're...

    M936A1 crane ops- basic questions for engaging transfer case PTO

    I'm going to inspect the crane hydraulics of a M936A1 that is reported to not work and I want to get knowledgeable on crane ops before I go see it . All I know is "PTO engaged but no hydraulic pressure to crane" so I'm guess this has a high probability of operator error. And yes, I have all...

    True failure rates of the 6CTA8.3L injector pump?

    Thanks for the suggestions- those are great tips. I should do that to all my trucks as I'm sure there is a ton of gunk in the lines and other system parts.

    True failure rates of the 6CTA8.3L injector pump?

    I've heard of guys taking a cheap hand pump garden sprayer from Home Depot and filling it with diesel to recover tractors, dozers, etc. stuck in the field. You can easily vary the amount of pressure you have from 5-30psi by how much you pump it. The couple gallons of diesel is more than...

    True failure rates of the 6CTA8.3L injector pump?

    You know, the funny thing is I wasn't thinking too. I knew they were 1/4" tubing but I'm so used to connecting them to our pumps with 1/8" NPT nipples that I got used to calling them 1/8". <insert face palm> And yeah, we use an 8mm wrench to push against the release ring but sometimes...
