My genset had a bad I/O module but before replacing it, I could crank and start it. After replacing that it will crank, start briefly but immediately shut down with a low oil pressure alarm however I know the oil pressure is good. Tried to start it with the battle short switched on but that...

Recently I won this M812 from GSA auctions which had been turned into a water tender for a rural fire district and several sources have told me that the truck is somewhat different than a standard lwb M809. Of course the most obvious difference is that the truck is on 14.00 tires and is over...

Here is my situation. Got the machine from GSA Auctions and on first start this is what I have discovered. CIM turns on and displays an oil pressure fault. Engine starts easily but no network fault light before cranking it. Fault cannot be cleared. After starting the CIM shows no voltage...

is there any description available how the air over hydraulic system functions? I assume the master cylinder provides hydraulic pressure to the air assist cylinder which itself then adds pressure to push the fluid to the wheel cylinders but how does the air assist do this? I also am...

with coolant level low there was no noise coming from the water pump but after filling cooling system all the way, the water pump is making a noise something between a squeal and a grind. noise seems to be at all rpms but as the engine rpm drops, the noise momentarily goes away then returns...

since discovering this truck today on Craigslist...My mind is aglow with whirling, transient nodes of thought careening thru a cosmic vapor of invention. but in the meantime, who can tell me about these triple reduction front hubs they have? Did these manage to actually work in real life?

just thought I would see if anyone here can recommend an equipment hauler I can contact to move the crane shown below? weights 26k#

yes, I know these are an extended frame version of the M39 trucks and very excited to make this one into a combination crane, dump, rollback rig much like the M54A2 I used to have. will need to add the hydraulics like I did on my last truck so if anyone has one of the adapters to take power off...

does anyone here have a good source they can pass on?

so it has come to my knowledge that the US Forest Service contracts for privately owned trucks during the summer to carry water for crews fighting wildfires here in the west and what I am hoping to find out is if anyone here got their 5ton in this program as they would seem to me to be an...

closed the deal to buy a 1973 M543 from the east side of Washington State. Literally am buying it sight unseen except for photos here but am told the truck has a mere 826mi on it and is 100% running and operable with the exception of a few small issues. Delivery scheduled for Labor Day...

so I have an NHC250 which came with paperwork indicating is was rebuilt by the Army in 1995 but been not run since. My question is what steps beyond the obvious are required to bring such a long dormant engine back to life? I have pulled covers and inspected the valve train...all looks good...

in search of info on M543/M62 hydraulic pump setup I am soon to install a large hydraulic pump on my M54A2 using a M543 pto off the transfercase but having difficulty finding photos or drawings of the coupling arrangement used. Looked in all the TMs but seem to be missing the exact pages. If...

this could be a doofus question but I want to install a hydraulic pump to a PTO off the back of the transfercase on my M54A2 but since there is no neutral position for the transfercase operation how am I supposed to be able to run anything hydraulic without being in motion? is this not where...

obviously deuce and a halfs are all quite popular for conversions and modification to different configurations but has anyone at anytime contemplated or even better still completed a conversion of one to a half track? Not that I am planning to do such a conversion myself since I do not have the...

I am contacting brokers to get quotes for transporting the bed I bought in Montana to Western Washington and do not have a true weight to give them. Based on the experience of others here, what is an accurate weight for a bed with bows, seats and canvas to use? also, if anyone has any leads...

GSA trucks in Arkansas & Texas anyone pick up an old Kaiser or AM General the other day? Most looked pretty well worn and I think all were listed as incomplete and not running but still there was some very classic old Army iron down there and in Texas. All too far away for me tho.

Due to possible brake problems that would make a drive unsafe from Sumas to Sedro Woolley, I am checking early if there are any members here who have the equipment to tow my M54A2 down highway 9 on a day in August? Hopefully brakes will be ok in the end without major work but if they require...

Sorry for the newb type question but I have an option to buy an almost mint 14' bed for my M54 from an M923 with full canvas for $500 however I have to spend $700 to have it shipped from Montana or I can buy a M809 series bed with dropsides locally but without canvas and not in as good of...

other than finding a fifth wheel hitch and running airbrakes and power to the trailer, is there anything else to do to use a standard 206"wb chassis as a tractor? I might have a line on a 30ton lowboy trailer near where I live which I think my M54 might pair up to very nicely.
