My Dad had a ‘72 R686 with a 237 and a Maxitorque T2050 five speed with Mack 38k rears and a Camelback suspension, plus a ‘58 B61 with 180hp 673 and a Quadraplex with a fixed tag axle, both without power steering. He always praised the Mack powertrain and called other trucks component trucks. Although he had high praise for the Detroit Series 60. You just couldn’t kill those old Mack’s!

@NPC-mt1cz no misconception. You are correct about Mack rating their engines at the wheels versus flywheel, but their stock and trade was their fast torque rise. This truck is a prime example......5 speed transmission and the ability to run above 65k gross combined weight. The Big 3 weren't doing that on a regular basis.

When we were using 5 speed R models for pulling log trailers we often had to get a skidder or dozer to push them away from the loader because they couldn’t take off in the soft ground loaded. 6 speeds could. I do miss driving R models though, the sound and feel of the transmission is unlike any other truck!

Back in the mid 70's my dad had a number of R600 with twin sticks. I believe the one stick was for the five gears in the maxitorque transmission and the other gave direct, low and reverse. Low was only used in first gear, so the effect was a six speed transmission. (I was pretty young back then so I may not be remembering this correctly). Anyway, our trucks often had to start out heavy loads (120,000lbs. or more on five axles) in the soft ground of our sand pits. With the truck in low range in first gear it would crawl away without having to touch the throttle. Back then my dad was able to order custom trucks from Mack and have them tailored to our needs. This made them a very effective truck and the R-600 ended up being the only truck my dad would buy until Mack stopped making them.

That must be a pre-1975 R600. My dad owned nothing but R600's (starting in 1975) but I've never seen that style dash before. Back then our trucks all had twin sticks and a very low gear for starting in the soft sand of our pit. At idle you could slide the stick into first with the clutch engaged and the transmission would give one click (no grinding) and then the truck would start to crawl ahead. A very low gear indeed. I miss the sounds in this video.

I had a neighbor friend when I was a teenager who had a 72 R-600 that had a 6 cylinder Mack with a 5 speed gearbox. The tractor was set up for running chemicals and it had a pump on it that we rebuilt several times. I remember that he would run around 20,000 miles a month and he would bring it home to do the maintenance that we could do on it. Give it a bath and then he would be out on the road. He would mange to be home for awhile most days and then weekends. I was broken hearted when the news came that the crankshaft broke somewhere in Connecticut and he sold it for parts. Then he bought a 82 Binder Conventional with a Cummins and a Roadranger. At that point I was 18 years old and he taught me how to drive it. I had my Articulated license until he got divorced and moved to Illinois and then the government started with CDL’s. I had been injured in a motorcycle accident and I was concerned that the state wouldn’t allow me to continue driving. But that old Mack was a great part of my teenage years. Watching this brings back memories.

But I found that driving a Mack five speed vs a non turbo 6-71 or 8v71 Detroit is vastly different. The revs drop so quickly on those two cycle Detroits that you have to shift at lightning speed or blip the gas between double clutching. Meanwhile you have to wait for the revs to drop on a Mack five speed before shifting (read a short book! 😁) as I learned on an R model flatbed with a six speed T2060 with an Eaton tandem in 1991. Even driving a Series 60 is vastly different than the two cycle Detroits as the revs drop far more slowly. The revs didn’t drop quickly on the big Ford gas V8s like the 477 and 534.
