You guys might remember my posts from 2016. I replaced my LDS with an LDT from a duece. Ran alright for a good while, I have put this baby through a ton of work! But, that engine was a bum from the beginning. The rear piston sleeve was loose and has gotten worse. Antifreeze is everywhere. It is...

I am pretty new to mechanic work so I hope all this makes sense. I have an M51a2 with an duece LD465 in it. My fuel injector self destructed. I got the new on on but I'm pretty sure I have the timing 180 off. The lifters looked the same to me anytime I rotated the crank to the markers. Now...

Someone told me that this is my governor but I wanted to check in with you guys and make sure. Its a cylinder shaped object between my steering pump and injector pump. It had 3 springs in it that blew out the bottom and are now resting on my axle. See picture below. I have a couple questions...

I have an M51A2. There is a big hole in my lower exhaust pipe. I took it down to the muffler shop and they want to replace my whole 3.5" pipe with 3" pipe since that is the biggest they can bend. I have two issue with this. 1.) Can this impact performance in any way or nothing to worry...

Im painting my m51a2 dump. Its CARC 383. I am using Behr paint which of course can't be used on the exhaust or engine. What should I use to paint my exhaust pipe/engine? I was concerned about getting the colors to match. Also, are there any concerns when painting the top of my engine. Was...

How many hours should a shop charge me to swap a head gasket? Now into the story. I bought this LDT engine and the previous owner told me he had just put in a new head gasket. Got the new engine in and sure enough, it still had a blown head gasket on the rear head. Had a friend who swapped the...

Anyone know what the idle temperature should be on these trucks. I am having a hard time telling if my temp senser is working. When my truck is running the needle vibrates back and forth pretty hard and its hard to tell if it ever leaves its idle location which is around 120 degrees. If I...

My radiator cap overflow is gushing out water the second the truck starts. Than it kind of slows down and intermittently blow out water until the fluid gets low. I bought a new cap to rule that out but I am unsure what else may be the problem. After you turn the truck off, you can hear water...

I am restoring this 1974 M51A2 Dump which is currently 3 camo green, black, and brown. I was doing some reading I guess everything pre 1975 was just Olive Drab? Having trouble deciding to go Olive or 3 camo. Opinions welcome! Either way, there are a lot of codes listed on the painting page...

I am looking for any information, schematics, videos that could help me with pulling the engine out of an M51A2 and replacing it. I bought this truck off a car lot that abused it. She threw a rod 2 miles off the lot. I have found a replacement engine but I am no mechanic and have never done...

Alright, I threw a rod in my M51a2. New motor time! I live in Newport, WA. So any local help is greatly appreciated. I am no mechanic. I will be be swapping the engines myself based on information here and what I can find on youtube. I decided to stick with the LDS or LDT to keep the truck more...

I bought a 1972 M51A2 dump truck with 397 miles on it. She sat in a county warehouse until recently. I changed the oil and some fingernail sized chunks came out. Against my gut feeling I tried to drive it home anyway. 2 miles from the lot cruising at 45 MPH, she threw a rod and broke a 2"...

I am brand new to your world. I just found myself with the opportunity to purchase and M51A2 with 400 miles on it for $4500 and I could not resist. Apparently our county bought it and stuck it in a garage for 40 years. It starts right up, drives around, Bed works great, but is spewing oil like...
