I was look over his truck and thought it was a little odd that it was speced with camelback rears....most new lowboy trucks are all air ride. At least he won't get stuck

Yep that was me. I parked next to him, was picking up a combination going to a chemical plant in Lemont. When I pulled up He was trying to fit both those machines on and having to reposition them to make it work. I gave him some eyes so he did not have to keep jumping out to check clearance for the goose neck.

Looks like a standard rs700l hood to me?

Think it's always parked inside his shop now....before it was always outside sitting near the fence off rt12

Are you sure it's a 300? Most 300 had a 5 or 6 speed behind them. 350s had transmission options of 8 or more gears. Regardless they are pretty much bullet proof engines...considered the Chevy 350 of Mack motors. Anyone can work on them and parts are cheap

R Jones R model always is clean I honestly done remember a time I saw it when it was dirty. That truck is always looking good!

I run a 300 mechanical all day at work. 2100 rpm up and down the hi way no problem. For years people ran these engines flat foot untill they needed rebuild. If you have the gears and can cruise them on the hi way around 1700 it's better but 2100 won't hurt them at all.

Yea they recently put in a 2nd track on the old ej&e main... Think its a siding . I brought a dozer to tower rd where they made made a retention pond.

I live 5 miles south of there on 83 few weeks back I brought 2 machines to the CN near the old leithton junction.First pic shown of the tower that guarded the junction. You can see a string of cars in the background. If you go to the left that's where 83 and diamond lake road is http://www.google.com/search?q=leithton+tower&safe=off&client=safari&hl=en&source=lnms&tbm=isch&sa=X&ei=I1F4UqnuLuTeyAH7uIC4CA&ved=0CAcQ_AUoAA&biw=1024&bih=672#biv=i%7C3%3Bd%7Cx97mv3-Kyw6U5M%3A http://www.flickr.com/photos/7547061@N02/5006308791/

Amazing how much Mack has done and built for our country. Trucks,busses,military, trains,

Tanzillo #1 R700 edwards rd dmm lime truck

Lol....did someone spray some sent on that truck that attracts deer? Glad your ok. 5 years ago I hit a deer on Christmas eve. It was snowing ,about 11 pm , flat land 2 lane road ,just jumped out of no where. I think he was hiding behind a tree lol.....sounded like someone threw a basked ball at the cars hood. It took out the left headlight and minor body damage. We got lucky

Replace air gov or check signal line. Simple fix

2100 loaded 2300 no load...per Mack's specs They will turn faster but valve float will become an issue. I don't know exactly where that happens. But suspect around 2700-3000 Our sled puller turns around 2500 and was told to not spin it faster.

Machines and chains are weird. For example I moved a cat 314 excavator today. Chained the boom and put binders on all 4 corners. Tight as I could. When I got to the job 2 of the binders were slightly louse. You just cantw always get the all the slack out of the tracks untill you crank down on them a few times after you have driven a few miles. Dozers I put blade rearward and in the center of the deck. This is for weight balance and ease of loading and unloading getting it centered on the deck. Combination and rubber tire always go bucket into the goose neck...regardless what some book says. Real world experience is what works best for me. But that's just my .02 To me this pic looks like a few issues. 1 Lack of chains or binders? 2 the machine did not have a good parking brake 3 he really hit those brakes hard for it to slide up and over like that.

I like to load rubber tire loaders down with the bucket pushed into the neck. Just like Peter did in his pic. Yea it's one extra step in the secure process but I like knowing the bucket is helping keep the machine from moving forward. Not to mention when you are hauling forks and a bucket. It keeps it in view and again easy to chain to the deck.one other thing, I wish all of the mfg of these machines would put d rings on the arm of these loaders. It would allow you to secure the arm and machine with just 2 chains/binders. Same at the rear. Some mfg put pick up points at the rear lower corners that really make securing them down safe and easy but not all mfg have the d rings at the rear.

Yea, saw it for sale on eBay a few years back .i don't recal who owns it or if a member here sold it...

If you pull a low boy the trailer neck is narrow and will not cause interference with the fenders unless you are making a sharp turn on an incline. That's where you have to be carefull. This is where a hi mount 5th wheel helps get the space needed between wheels and trailer bottom. Another option is that Some people run half fenders on the truck and half fenders on the trailers goose neck.

E7 300-350 or 400 is one of the last good mechanical Mack engines made. E6 was just as good but the e7 have more grunt

It really depends on how tall your 5th wheel is and what type of trailer you will be pulling. Camelbacks have lots of articulation so you want to find the happy medium between the top of your tires and 5th wheel surface. If you have a hi mount 5th wheel and plan to pull flatbed,end dump,or tanker trailers the fenders can sit up high as those type of trailers tend to have much more clearance betwwn the tires and bottom of trailer. If you plan to pul van trailers you need to really check for proper clearance below the 5th wheel. I set mine up to pull lowboy and end dump. They sit kinda high and when I have a van trailer hooked to it I have to be real carful. As far as mounting them. I jacked up each rear axel and measured the max amount of wheel travel they had above the frame. When I mounted the fenders I set them about an inch higher. If I recall I had about 6" of upward travel at each axel when making contact with the frame stops.

If i was in the snow plow buisness I would personally rather have a fiberglass hood r model with the side access panels. Less rust issues and light weight. Not to mention when the plow is off its better access to the engine. Always wondered why peoplem kept buying steel hoods after the fiberglass hoods became standard. Wisconsin dot had a lot of sloped hood rd Mack's with this set up and they seam like they way to go in my book..

Why did they continue to build steel nosed r models after fiberglass became much more popular?

You can do it 2 ways. Run it up to 2100 then shift. It will fall back to around 1300 and start pulling again Or run them up to 1800 then shift. It falls back to 1000 These engines don't pull real hard past 1950. And they make most of their power around 1200rpm... Thats how I drive em

Yea 355 on the west side of the highway. Been there all week...

I saw both of them... Looked fairly clean
