although I don't own any M939-series trucks, you shouldn't have any issue doing what you want on-road other than the obvious "tractive" issues which others have mentioned.. I have for several years operated a couple of my M809-series trucks without the rear/rear driveshaft as well as without...

all those things you and other's mention will help .. have you also considered rotating the axle 180* and bolting it to the top of the springs? .. Being you aren't going to road the trailer, it won't care about the change in camber and would very slightly increase the wheeltrack width...

correct! the carter pumps i used are 3/8 flow-thru's so-that the fuel will draw even if fuel pump fails

somewhere in another thread on here is the actual psi and flow data on the OEM in-tank pump .. IIRC, it is miniscule psi, something like 2 or 3 but is not more than 5 or 6.. On a couple of mine I use a 24v carter inline pump with 10-12psi with no issue for several years, and wired with the...

you forgot to include rolling backwards in neutral ;) .. the poppets are activated only by the reverse position and neutral position on the tranny .. By default, neutral affects the forward gears .. (cannot get to any forward gear without going through neutral first)

1: The sprag that is in that M51 is very tough.. Its transfer case, when maintained and operated properly, can handle more than it can be given... The spline on the driveshaft feeding it will break before you overload / over-torque the sprag.. Out of a half-dozen M39-series owned during the...

You lucky duck, there's a Mack in your truck! :love: (had a M52A1 back in the day)

Are you in Low range ? .My A1 maxes out at 29mph in 3rd Low

certainly some weird stuff with all 3 packs.. Are the gladhands still at the front of the truck and still plumbed? Shot in the dark but the one on the passenger side of bumper is supposed to be a vented cap and sometimes the vent gets clogged .. This can cause brake lock

I realize this thread is about the tranny PTO's, but if using a deuce T-case PTO (rear-facing) unit instead, be careful with the loading and operation of it.. They are found on fuel tankers and pole-setting trucks, perhaps one or two others.... They are supposedly tender inside. 40 years ago...

I didn't read through so many years of posts, but in case you didn't get an answer, your truck is an early A2.. Many early A2's had the LD465 with a downspout exhaust.. When I was at FLW in the 70's there were many A2 downspout M35A2's with the LD engine, especially assigned to the Motor...

my understanding is all M44-series deuce axles are the same regardless of year, 1951-up .. I do not know if the ones in the cat-powered A3's have anything different

Bought and recovered a Bucyrus 10B shovel long ago .. Fortunately on hard ground but in a stand of poplar and sumac which had grown up around it.. Luckily none of the cables were encapsulated... The only trouble with this move was picking out the "potatoes" caught in the track chain...

My place became exactly that by default, no "set up" required... Since the late-1980's I planned for a certain percentage of the business equipment/trucks/machinery to provide retirement income.. By default, the "boneyard" is parked under protective pines and inventory grew over the decades...

I hope your M5H6 (and the CCKW) come out from their "holes" fairly easy.. My subject M5H6 (dragline on its back) is encapsulated 18" deep in (virgin Champlain) hardpan clay .. ;) Might as well be trapped in 18" of cured concrete. Am not here to hijack your thread but was hoping my...

yeah, sometimes chewings were unjust and only created hard feelings and negativity instead of helping develop a Soldier. Especially when Soldier is witnessed doing the right thing but the device fails at the worst time .. Some of those clips weren't the grippiest of things, some were sprung out...

yep! exactly !! ... Now I know the feeling all those people and businesses that invested in tons and tons of WW2 and Korea surplus had felt when the 1980's-90's came.. So much got scrapped due to market and locations. 15 miles away from here was a large dealer with crates upon crates of...

yeah i hear that ! .. For 5 years i have been putting off yanking a 1944 M5H6 that was my friend's grandfather's construction company rig.. Has a Bantam 40ft dragline on its back and has settled to above its axles in clay , sitting since 1985 or so .. Not gonna be fun , even with the M62...

They sure are heavier and heavier-duty ! .. Thus rare to see cranes and shovels on the backs of CCKW's but they were out there.. It was a more-common retrofit on war-surplus M5H6's (and heavier 6x6's) for awhile.. Seabee's / USMC had cranes/shovels on M5H6's during the war, even

I concur with NDT .. WW2 combat wheels and the 1950s-up combat wheels are not the same animal .. For starters, the WW2 20" standard wheels/rims are narrower than the later wheels/rins
