Driving a 40 Year Old R Model Mack 5 Hours... What Could Go Wrong?

I drove many a Mack. Never had 1 break down ever. Thank your lucky stars it's not a camel back suspension like my 1st 1 was. Eventually I worked up to an R model with a 350 Mack 10 speed Eaton, air ride suspension and cab. I thought I was in heaven. Also never got less than 10 mpg. Part of me misses those days. Not my new knees, sore back or my varicose veins. But somehow you've got to love a truck that never lets you down. Now that's something you can't say about people.

A friend of mine had a 72 R-600 that he hauled chemicals with. It had a Mack 5 speed gearbox. I would help him with maintenance on the weekends. I have to say that when he had to get rid of the old girl in 83 it broke my heart. When you crank it up it took me back.

Macks are the one truck that are still being made that I have still yet to drive. I have always liked their looks. That old girl is a beautiful example. She reminds me of a dump truck that a driver in my childhood neighborhood used to have he pulled a transfer pup trailer with his. Thank you guys for sharing this litle video with us.

I just bought a 1/34 diecast model of a red Mack R double axle truck towing a P.I.E. (Pacific Intermountain Express) trailer. Since I have been watching your videos I now have a renewed interest in Mack R model trucks. I am a diecast collector and have been collecting Mack L's and Mack B's for years. This is my first Mack R.

[@Redhens303]

I love R models, but they are hard on the driver. Ear plugs recommended! My first R model was a 1976 model with 237 engine, air starter, 5 speed, twin screw. It did not have power steering nor air conditioning nor AM/FM radio. Next R model was a 1980 with whopping 285 engine, 5 speed, twin screw AND power steering AND A/C, AND AM/FM radio with cassette! Wow! Luxury! Both had camel back suspension on Mack rears: VERY bouncy when empty, bobtailing shook fillings out of my teeth! I logged well over 100K miles on these two farm trucks! Never had a breakdown on the road I couldn’t fix with my basic tool box stowed under the bolted passenger seat (no air ride for the passenger!). Never had to be towed or rescued. 5-6 MPG loaded, 9-10 MPG empty. Good Ole Days!

[@bradh74]

The R Model I drove was a dump that had the engine turned up in it. You could not drive it with a load on without smoking out the people behind you. It was terrible for "rolling coal". The other old Mack's had the off set cabs on them, that company had a lot of mixers like that, but, my favorite was the 98 not sure what Model it was, but it was a nicer truck and rode the best. The Camel back suspension was good too. You probably need to turn the heater valve or valves on for heat. Look where the hear hoses go to the firewall on the passenger side and follow them to the engine to find the valve. Some had 1 and some had 2, you'll have to take a look. Hope it lasts you another 40 years,but don't have to go so far!

[@kvoigt19]

This brings back memories when I worked at the Farmers Cooperate. We had a 1980 Mack with a paltry 237 with a 5 speed pulling a hopper grain trailer. To call it a gutless wonder would be an understatement. This was a fun video. Thanks!

[@stevehaller6332]

One farm I worked on years ago twin screw R model Mack’s was all they had. I loved them because they could handle whatever load you put in the grain trailers. All of them could run maybe 58 to 60 mph tops if that but do not worry about the bulldog just load the wagon

[@RJ1999x]

My guess is it had problems they ignored, because a true Mack wasn't a gutless wonder

[@stevehaller6332]

@@RJ1999xyou are correct it is called maintenance such as changing engine oil as required, the fuel that is available is not what it used to be so fuel filters need to be changed more often, which would lead to injector pump problems also. An injector problem is easy to figure out because the engine oil will be thinned out with diesel, the same thing if there is a seal out where the injector pump is mounted. Otherwise if everything if working like it is suppose to on the fuel system that little paltry 237 Mack engine will pull what ever load you put in the trailer straight up the side of a grain silo at the grain coop

[@RJ1999x]

@@stevehaller6332 you are correct. Me friend had a DM It had a 4 and a 2 if I remember right, dual lo was if you were going straight up a silo. I was told that a Cat or Cummins 250 was 250 on the flywheel, but a Mack was on the wheels, which makes a big difference

Just a quick suggestion for changing gear (shifting) on the old gearboxes. Put some pressure towards neutral on the gear lever and then dip the clutch.

Check that both valves on the heater lines are open. Should be one near the water pump and one closer to the heater core. That would be a good place to start trying to solve the no heat issue.

I drove a similar early 80s Mack 5 speed tanker. Did this as a volunteer firefighter. In the hills here in NE PA it could be a challenge at times. With 2000 gallons of water once you got it moving it rode nice. The Mack plant that built our truck was about 25 miles from our fire district. We sold it about 8 years ago because the frame was too compromised. A farmer in (i think) upstate NY bought it to move water around his place.

[@johnviney7919]

Always good to get there safely! A few items to fix up but truck looks and runs really nice. In my opinion, I would like to drive a loaded rig rather than bobtail any day except that they run like a greyhound when they're empty. Have a nice week you guys!! 😀

[@thefarmergrayce]

Me too!! Bob tailing is fun for a few minutes but then it starts to hurt 😂

[@ASkepticsPerspective]

WOW does your video bring back memories. I am a 65 year old retiree. But from the mid 70s through the mid 80s I bobtailed a lot of Mack trucks. My dad owned the Mack Distributorship in northern British Columbia. Driving those trucks was a great way to make some pocket money. I use to pick up new trucks in Vancouver and drive 10 hours north through some incredible mountain passes. Or I would drive from Edmonton, which was an 8 hour drive west through the Rockies. I would also deliver new vehicles all over northern BC and often try to drive the trade-in back. Some of those trade-ins were real pieces of crap, so I understand the feeling of driving while wondering what was going to break next. There was only one I ever refused to drive because it was so unsafe. The sales manager hired another driver to drive it to PG and the engine blew up within 30 minutes. I felt vindicated! I drove lots of R models, cabovers, superliners - most of the vehicles I drove were dual axil. I ended up getting a kidney belt to manage the ungodly bouncing you experience when bobtailing trucks. The longest delivery I made was of a new dump trunk that I drove from Prince George BC, to Whitehorse in the Yukon. That was a 3 day drive. But enough of all that - As we use to say, keep on trucking!

I can just imagine how that rear axle would kick when it hits a good bump with no weight to settle it down, the joys of bob tailing a completely leaf sprung truck. This reminds me of ( although much worse ) of our first highway tractor we bought for the farm, a well used GMC General with the 8V92 turbo engine and not only leaf sprung but the steer axle had the thick multi stack springs that road just like a lumber wagon, its hard to describe how awful the ride was. I soon changed that out to the three leaf tapered springs like you have in you're Mack, that was a big improvement. I thought the steering wheel might come off into my hands, frick it was god awful 🤣

Years ago, I met a bloke who ferried new Macks all over Queensland to the buyers and then was "supposed" to bring their trade-in back with him. Many times he would take a new truck to some very remote cattle station ( ranch ) and then be confronted with the prospect of driving some old R700 all the way back to Brisbane - bobtail! Usually, he'd get a ride into the nearest town and hire a car after telling the station owner he could keep his trade-in and he would keep his back from even more damage! 😂
