Thanks for the advice, the compressor I am mounting has some pretty serious filters and two water traps so hopefully it will do the trick. I will check with the Sullair dealer in St. Louis, that also happens to be the brand of my compressor. I caught two of my sons today dragging a jackhammer over to the compressor so they could "try" it out. I asked them what they planned to hammer away at to test it and they looked down at my concrete floor. They were just trying to help. They got sent to the house.

Why did they outlaw sandblasting? Did someone spray his toes and get an "ouchie"?

Can anyone tell me a good brand of a large sandblaster? I have a 175 CFM skid mounted compressor with a John Deere diesel engine that I removed from a mason's truck that I am going to mount outside the shop to sandblast with and blow out combines. I have started looking around and a lot of what I am seeing is pretty junky Chinese stuff. Does anyone have a good recommendation?

Hey - Thanks for the update and for taking an outside shower to watch them sell! Do you remember what the green Mack brought and also that real old Cox car that looks like a buggy? Thanks again!

Congratulations to me, in just one too many raises of my right hand at an auction, I am now the owner of TWICE as many Macks as I owned before! Okay, so I only owned one before and now this makes two. It is a 1973 R686 that appears to be a former dump truck that they slapped a cracked fifth wheel onto some time ago and made it into a lowboy tractor. I am needing several under the hood parts for a 1971 Mack DM600 that we installed a different motor into, and this was just what I needed. On the doors they have stickers that read that it is a positive ground truck. I wonder how many batteries being jump started were toasted before they were forced to put the notice on the door? The truck has a pretty new starter on it. Can it be used with a negative ground truck? Check out the photo I included of the mighty fine non-factory drivers fuel tank strap. I don't think a piece of rusty cable and the bent bolt for a hook will pass DOT inspection - she is a peach! The worst thing on the truck is that someone installed a Kenworth seat for the driver - what an outrage! Then, while it was being hauled here and spending the night at some truck stop, some Mr. Jackwad and his Lot Lizard friend stole the bulldog off the hood. That is just wrong. I was really surprised at how small the frame is on this truck compared to my DM. It also only has a single frame. I also noticed that the rear axles have five spokes instead of six and the gear cases on the tops of the rear ends are aluminum instead of iron. Does this mean these are light rear ends like 17,500 or something similar? I doubt if it will ever run again, but it will contribute lots of parts to keep my good one on the road. It sure is educational to take something apart.

Gents - If anyone going to this auction reads this, could you when you get back post on here the prices some of these trucks sell for? It is not necessary to keep track of the Volkswagon "collector car". Thanks in advance -

Neat shot - My first thought is that I am glad I am not the flunkie having to check the air in 158 tires!

I am blowing pepsi out my nose as I read this - Classic! I keep finding new possible meanings that all come with funny visuals.

AMEN to that!

My sons and their pals all do the airsoft gun thing. A while back they all hid out behind some trucks and waited until I was hooking up to a trailer and when I bent over to crank up the landing gear, they all cut loose. I honestly thought that I had gotten into a mess of ground hornets! I started running away and waving my hat at the imaginary bugs that kept biting me and then I realized they were little colored balls! I think I still have some in my crack and chest hair. Those things STING! It has been fun seeing them naturally be little gear heads and compare their different guns and attachments just like adults do with their toys. Only a real man would take it in the shorts on purpose!

I ran a 35 ton Rogers detach trailer for many years and they were good stout trailers with that suspension. I have noticed several of them at auctions with the box tubing on the suspension rusted through, you might be sure and crawl under there and check that trailer for that. Ours was like that when we bought it (it made it cheap to buy!) and we just plated it well and never had a problem. All the wear stuff in the axles we could just get off the shelf at the parts store. I liked the low bed for hauling big round hay bales, you could really stack them up and not be too tall for the low bridges around here. I wish I had it back - good luck with yours.

I have seen several fifth wheels that pivot both ways at army surplus auctions, and we have used them to pull gooseneck and camper trailers. The ones we had had a pin that you could use to latch the fifth wheel back to a normal position when you were just pulling a semi trailer on the road. You might try Memphis Equipment in TN, I bet they have some junk trucks with one on that they would sell. Those fifth wheels work great pulling loaded log trailers out of the woods where the going is really rough. I also have taken two trailer kingpins and welded them together with a 1 inch steel plate in the middle and that works great to pull a reverse fifth wheel camper trailer. It adds enough "slop" that it does not put the camper hitch in a bind when pulling it with a road tractor. An old Mack would look good pulling into the trailer campground!

That guy remembers the boy scout motto! Or he might be selling bootlegged ice cream cones out of that thing for side money.

I am installing a 1981 E-6 engine in a 1971 DM600 that formerly had a 673T in it. The puff limiter on the E-6 was broken when I got it and the air lines are bad. Do I need to supply air to the injection pump to get around the puff limiter so that I have full throttle travel in the pump, or do I need to just block off the air line that feeds the injection pump? What are the advantages of finding another puff limiter and having it working? Thanks!

I need those chrome tow hooks on my log truck!

I am a farmer but I also own a tree and crane service and we used to just pile up and burn or let rot all the junk logs we bring home. But we found a couple of sawmills not too far away in a Amish community that will buy ANY logs for pallets and blocking. I never in my life thought that someone would buy elm, box elder, locust, hackberry, or any other junk wood! What used to be a waste is now a good deal. We haul a couple loads a week to them and while they do not pay a lot (24 cents a board foot), it is a nice extra check each week. The load in the photo was 2992 board feet but I have had on as much as 4100 feet on a load with some good straight 40 inch diameter logs. The more you load that old Mack, the better it drives and pulls. I started the Mack yesterday and it ran without any knock I could hear, but it vibrates like it is missing on one cylinder. I did a temperature check on the exhaust manifold and the exhaust for the #1 cylinder never warmed up like the other five did. I pulled the oil pan and there are not any large chunks of metal but there are some small flakes like bearing wear. We turned the engine over and there is compression coming into the bottom of the engine from the #1 cylinder. I took off the valve cover and everything there checked out okay. I think a ring broke on the #1 cylinder and got on top of the piston. This morning I am going to pull the bearings on the #1 cylinder and see what damage I find. I think I am going to pull the engine and replace it with a used 237 I found. I just wonder if it will bolt in place. I called a Mack dealer and he said it would as long as it does not have an aluminum front cover on the engine. This one does not so I hope it fits.

I found a used 1981 EM6 237 engine. Will they bolt in to my truck or does it take a lot of work to make them fit? Just to look at it, the only real thing I see different is that the 237 has the turbo lower on the side of the engine instead of on top on the 673. The EM6 also was in a firetruck with a Allison automatic. Will that be the same bolt pattern as my Roadranger 13 speed has?

If you need one, I have an extra aux. transmission that is in good condition, the truck only had 70,000 miles and it worked smoothly. Let me know if you are interested - (573)219-6611.

I am a farmer in Missouri and I have a 1971 DM600 that I use for a log hauling truck. That is one tough truck! The engine started knocking today and I need to rebuild or get a replacement engine. The plate on the door reads that it is a model DM607S and the serial number is 6712. The truck has a 13 speed Roadranger transmission which looks newer. The build sheet for the truck reads that the engine is a END673E Thermodyne. But the engine has a turbo and my book reads that the END673 was non-turbo. The engine has rebuild plates on the side with depot numbers so I think the truck started out in life as a military truck (the olive green paint helps as well). The plate reads that the engine serial number is 4K4485. There are raised letters on the block which read: 288GB5320A. There is also a plate on the drivers side firewall inside the engine compartment that reads: U-24688. My questions are: What model engine is this so I can find a replacement? Also, is the transmission original? If not, will a replacement engine bolt up to it or did they have to modify things to use that transmission? Does anyone have a good used engine? Thanks in advance for your help! Check out the photo that I included of the Mack hauling some pallet logs - can you find the white cat on top of the load?
