- This is the first time towing with the new transmission since the swap. It is a huge improvement over the old 6 speed. It shifts much faster and has a much nicer top speed.

Gosh those cabs are small
Cool video and thanks for the ride along. Truck sounds great!
Yes they are i am 6' 4" and love the old bull dog's but not comfortable for me, no knee room
Here in MA, I work for a contractor per deem/part time, and he has a ‘73 R model 6 wheel dump truck and he swapped it with an 8LL, since I’m still technically a noobie I’ve learned how to really up and downshift without the clutch in that truck even thought I got my Class A with a 10 Speed International tractor and a trailer. All around fun truck that old R model is, I love how loud it is and how smooth it drives. Yours sounds really nice
Thanks man, it is a fun truck to drive!
That engine sound good!
top speed with the 9 speed?
Just bought a 94 mack rd688sx 123 foot crane truck... never drove 1 before so i ask... y are you using the clutch? Dude i boufht it off of said float the gears.. n only use the clutch for 1st and reverse
Redford excavating I am looking for mack for sale?
Do you have a Jake brake on this truck like the R model Mack's to good old school trucks thanks for the video
We just added an engine brake when we swapped the engine out for a 350.
Really amazing truck, loved the one my grandfather drove for Chemical Leaman. What engine does she have?
Thanks! Its been an awesome truck for us, we love it. And it has a 250 in it, we will eventually bump it up to 300-350.
Why do you use clutch coming out of 6th gear, just wondering.
Sometimes it’s tough to get it out of gear without the clutch, so I use it on certain gears to make it easier to shift.
Your left knee and hip will thank you years from now.
While watching this I noticed you pass my company’s truck at the intersection 😅 small world
Haha, it really is a small world!
What company do you work for?
Ecotone inc
That's funny, I see your guys stuff everywhere.
@@tylerboone2786 I want to work with you as a assistant.
Where'd you get the transmission from, if you don't mind me asking?
We got it off a buddy, he had one lying around, so we bought it and had it rebuilt before having it installed.
what is your top end speed at at what rpm ? im looki g to buy a 367 with the 8ll transmission im wondering whata the top end apeed ill be able to get thanks
I had it up to 90mph the day we brought it home after the swap, it was turning about 2200rpm. On average, we can cruise 70mph turning 15-1600rpm. Its much nicer to drive on the highway now.
Redford Excavating if you don’t mind me asking what exact 8ll did you use ? Also what gear ratio is in the differential and did you leave the pto to manual or converted to air ??? I’m looking to do the same swap to my 285....... also if you have an idea who I can check for these parts that would be awesome.
I know its the high hp or torque rated 8ll, I cant remember the exact model # off hand, but ill try to find it for you. We have yet to check what ratio we have in the rear, ill see if there is a tag. The PTO is still air operated, but the fella that installed it sourced the new pto for us. As far as getting the trans, we got ours from a friend that was keeping it as a spare. It needed a couple gears, but we had it gone through and its been great. I'm very glad we did the swap, it has been so much nicer to drive over the old 6 speed.
What bell housing did you use?
I don’t know off hand, the guy we had swap the trans for us, found the bell housing. Ill see if I can find out for you though.
Best trucks ever
Was the old 6 speed really that bad? Or is the 8 just a better trans overall?
It was pretty bad, the new 8 speed made a world of difference.
How weight do you usually haul?
We typically haul 10 tons since its a single axle.
What engine it has?
Makov motor mislim da je Endt,Maxydine ili E6.
What model year is this truck?
It’s a 1987
@@redfordexcavating3834 It's interesting how this Mack R-Model has it's fan mounted to the ceiling. Most R-Models that had fans had them mounted to the dash.
Mate this is one awesome vid but do you think you could make another driving vid like this but with you using the clutch every time you shift?! I have always wanted to see a driving vid like that mate hope you can make it for me mate! Cheers!
The style of driving for American class 8 vehicle ( trucks ) all use the double clothing method... you depress the the clutch go into neutral depress the clutch go into first depress the clutch go into neutral going to second and repeat whether you're upshifting or downshifting
@@gregorywomack9416 that’s an awesome style of driving I was just hoping that maybe you could make another driving vid like this one. Super interesting!
@@dennyalfro9832 that wasn't me driving lol... but I am a certified diesel technician and been working on those trucks professionally since 04
@@gregorywomack9416 OH DUH LOL SORRY my bad my friend lol didn’t realize it till right now lol!🤣🤣🤣
@@dennyalfro9832 no worries man haha
I’m trying to find an old R or U single axle Mack
He I got a r model id sell
Cassandra Townsend where are you located. I’m looking for an R model.
Have a gold Mack rd e6-300 8 speed mack ,mack rears , mack beam suspension, tank of a truck had original low gears , had it re geared now will do 75mph no problem ..solved my issues before only about 50-55mph probably alof cheaper than transmission swap
Kind of a dumb question but an Amish kid wants to know what is the most powerful engine you can marry to this? As a 5th wheel logging tractor.
This wouldn't be an old Cumberland Farms tractor would it?
It was a tractor that was converted to a dump truck. I don't know if it belonged to Cumberland Farms at one point though.
How can you listen to ear buds when you're in that truck?? Don't you want to hear that engine sing??
Why the swap?
Because the 6 speed really lacked top end speed, and it was a bear to shift on a hill with a load. The guy we got the truck from had swapped the 6 speed in place of the 5 speed that it came with originally. He lived down on the shore where it was relatively flat so it didn't matter, but where we live it was a struggle. The new 8 speed is light years better all the way around. We love the truck and plan to keep it so we figured the swap would be worth while.
Do you ever see any single axle Mack’s for sale up there? I want one for a variety of reasons but mostly because it would be fun to drive. Thanks for the info on the eight speed
Not often unfortunately. It took us a while to find ours, but if I see any pop up ill let you know.
