Saw a Greco R model today. And a few others

He might be thinking of theorally version 2 stick 6 speed that had a hi and low. It was an overdrive trans if I recall. one reverse, 6 forward speeds, ....start in low 1, 2,3,4, shift to 4hi, 5

Lol....I all honesty i was watching for cops in the construction zone...as soon as I passed you I said dammit he cought me sleeping again....

Serious question about Australia. It looks like its always warm there....do you spec trucks with heaters for the cab? Or is it just for a/c. Always thought the r models with out a under dash heater/AC unit was much nicer for foot room... Your cab looks like it has a smaller under dash unit kida like my truck has... My truck has a heat but no a/c and I have more leg room than guys with both.

Most likely a 237 does it have a turbo but no intercooler? 5 or 6 speed transmission. .. if so its a 237 maxidyne

Mine stays between 180 and 200....stays at 180 in winter even in good pull. .summer time it creeps to 200 and falls back to 190 in hard pull...rarely does it hold anywhere above 195...

Looks like pa hills in the back but the model of tucks says west coast....

Wow...very cool Did Mack continue to produce civilian trucks thru WWII ....or we're they regulated to making what ever the government needed them too...

Times like these when a camelback ant so bad....

I have dual 5" straight stacks and it's not loud in the cab. A single 5" will be slightly louder but if the exit is above the cab you will be fine....I would not go bigger than 5-6" anything larger looks like a cartoon in my opinion. Not to mention the drone and vibration it may have... Also I like a truck that can "throw" the smoke ....the big pipes just look lazy with smoke trickling out...

Before clicking on you tube video make sure you have the rest of the day free and don't mind wearing a big dumb looking smile on your face for the rest of the day! Vinny strap your self in.

I read your last post...unfortunately I haven't been out by my truck in a few weeks... Next time I'm up there I will take some photos of my rs700 mounts for you if no one here does first.

I have some green ones that were a little louse on the toggle...I used some gasket maker to secure them...

Mack diffs normaly have the auto power divider....the advantage to them is that when your driving thru a soft spot in the mud it kicks in on the fly as soon as it detects to much slip....way before you know you need it. It also releases automaticly when it sees normal traction. The down side of this is if it's worn out it may not lock in as quick as needed. For example if your stopped and know you are in the wet grass or mud you may have a little trouble getting started or getting the power divider to kick in. If this is the case this is what you do.. Release the clutch,if the wheels are spinning but truck is not moving, lightly stab the brake pedal and the divider should lock in and transfer power to the wheels with traction. The automatic power divider with camelback springs is one of the best set ups for the off road.

Wow very cool.....always liked those valuliners...I built a model of one as a kid, I thought it looked like a cool r model. I really like the dash layout. Much better than the us models. I like how the gauges are on one panel and switches on the other.....

I saw this one on the south side of Chicago last week

Last week they were filming in the north side of Chicago and down town...

Cab exterior is pretty much the same from 73-04. Diffrences would be cowl depending if it's a r model or later rd. Overall construction is pretty much the same thru years. A cab from 81, should bolt to a 94'. Electrical and air will differ slightly. Galvanized cabs started in 85'? Interior options had some changes thru the years mainly in dash construction and layout. Headliner was changed and overhead consol was added in mid 80's Door catch and latch changed in the mid 80's

Thankfully I was not on that job when it happend...heard about it and sounds like it was ugly....did not know the guy as he runs a smaller grinder that they move with their own rig...we just lowboy their larger grinder for them. I was in the south loop all day with them today and back out to the south side tomorrow...

Running with a road resurfacing crew the past few weeks.. one of the only Chicagoland crews that grind and pave all in the same day.. fast pace work often doing 2 or 3 locations per day. .

Another place to measure that may help figure this out is to measure what a r600 is from center of front wheel to front of cowl...then measure what a r700 and rs700 is....if I was up around my truck ...rs700l....I would measure for you..

ABC supply had a bunch a while back...never drove one but thought they would be a great end dump puller as long as they could turn good...still see a few red bulk haulers running around town...

I don't have exact measurements but a rs700 hood should be about the same length as a r700 hood.The difference will be taller hood hight on later model rs700 A rs700/r700 hood is about 10-12" longer than that of a r600 hood. As far as how far off the frame the cab sits....my rs700 was about an inch lower than the 2 superliners that I measured. I was able to use a superliner air ride cab set up on my rs700. If I recall the cab is about 5" higher than a standard r model.

Looks good....but I Ike the black r model t shirt better......ha ha!

I was at a acme scrap yard the other day and wanted to get a pic of this old r model but forgot too...it had camelback spoke rims but had thin sidewall solid rubber tires. Just a yard dog... It Looked wierd but it was trucking over scrap like it was not even there...
