Been kicking around the idea of selling my M51 dump. I bought it to use for hauling dirt and rocks when building our house, well atleast that’s what I told the wife. I really like it and have spent a ton of time getting it in usable shape but think I’d have more fun playing with a cargo style...

I was changing the master cylinder on my m54 last night and in the process I dinged up the threads on the banjo bolt adapter. It’s the adapter for the line from the master cylinder hooks to air pack. Looks to be about a 9/16 banjo bolt adapted to a 3/8” brake line. Any one know where to obtain one?

I've been struggling with my m51 having a lack of power. When I bought it the previous owner said he installed a different ip because the old one leaked. I've had to turn it up quite a bit to get it to start and run decent but still doesn't like to pull 4th or 5th gear. I noticed tonight it has...

Trying to get my old multifuel up and running. My problem is it’s lacking power. I can’t get past 3rd gear. Go to 4th and it just lugs and won’t rev. When not moving and you try to rev it goes to 1000 pretty quick, kind of slowly revs till it hits 2000 then does pretty good. About the same when...

I’m needing to do a steering box and ball joints on a new to me m1009. Was figuring I would do tie rod ends too. Looks like I can use moog parts for the same year suburban on the tie rod ends because they don’t seem to match for a civilian blazer. Will the ball joints be the same for a civilian...

I'm wanting to replace the wiring harness in my M51 multifuel dumptruck. All the wiring in the cab and under the hood is pretty sketchy. I couldn't find much searching or in the tm's. Probably not looking in the right spot. Do I need a "front" wiring harness? Will that do inside the cab and...

I’ve been reading threads on hub flips but most seem for deuces. And I can’t find anything searching. What size is the socket for flipping them on my m51? Harbor freight have em? I’m 8 hours away in Texas sitting in a hotel room waiting to get my lmtv wheels in the morning lol

Had to adjust the fuel on my M51 multifuel today, starts right up and idles great now. I think it might still be a little low but I want to install an EGT and boost gauge before I go any farther. What ones are you guys running? I'd like something that matches the interior and doesn't look to out...

M51 with the multifuel. Ever have the fuel lines leak where the attach to the hh? I checked and they’re tight. It’s hard to tell which one but looks like it seeps enough to drip off the side of the head. The previous owner installed a new ip and couldn’t get it to start. With your guys help I...

Anyone know where I can find the lower radiator mount bushings for a m51a1 multifuel? All I can find is the top rubber mount. Also where the injector lines screw into the top of the hh, is it just a flared compression fitting or is the an oring? Notice mine seems to be leaking from there

The drivers side fender was off my truck when I bought it. Was putting it back on today and there is a couple things I can't figure out. There is a hose coming off the p.s pump that has a quick connect on it. Not sure where it goes. And there is one on the engine/radiator side of the reservoir...

When I bought my truck the owner said he replaced the ip with a rebuilt unit because the original was leaking fuel. After replacement he could barely get it to run if giving it a hit of ether. He thought it was getting air in the lines. I checked the timing, #1 cylinder valves are both loose and...

I've been tinkering with my multifuel dumptruck when I have spare time, which is never. Changed the fuel filters, still need to dump the tank and refill with fresh diesel. The previous owner said he replaced the ip because it was leaking diesel and couldn't get it to start easily afterwards. I...

Just received my filter kit for my multi fuel from BigMikes. What oil do you guys suggest? Looks like it's straight 30wt. Seems like my other diesels always seemed to prefer one kind or another. Also just regular green antifreeze?

Looking at ordering tires for my m51a2 dump. I really like the look of the 395's singled out. But is there any good reason, besides having spares, to not go singled? It's a toss up between the g177's 11.00r20's and some Michelin 395's. Cost seems to be about the same. I read somewhere that the...

I have a guy picking up a M51A2 dump truck for me. I found where the length is 24'. I'm assuming that's bumper to bumper. Any one know the wheelbase or front of front tire to back of back tire length?

I posted awhile back about a truck but the logistics of getting it home isn't going to work out. I actually found one a mile from my work and 20 miles from home. It's a 1968 m51a2 multifuel dumptruck. Rebuilt in 1989. He said everything works and it starts but the injection pump was leaking fuel...

Hopefully I'm in the right forum, sorry if I'm not. Found a guy selling a 1975 5 ton military dump truck. He says it's a M45a-1 with a mack diesel but I can't find any info on google about it. I thought it should be a m929 or m930 but I don't know much about the subject, yet lol. Is there such...
