Saw that video the other day.He shows the Mack Western build plate on the door.I was surprised to see a 6-71 in it not something bigger.The fame is shot but lovely truck...I want it!!!! Paul

Engine wiring harnesses and EGR mass flow /temp sensors are almost impossible to get as well. It was actually a really good engine. Still lots of them on the road in my area. The 395 HP version has more Torque than the 405 HP.

The Powerleash engine brake is only for the ASET family of engines and wasn’t even available on the first year of those engines. Jacobs was still the only option till halfway through 2004. Lots and lots of service bulletins on updating the Jacobs on the pre-ASET engines. The high volume oil pump and external oil line kit helped a lot. Putting a Powerleash brake on a pre-ASET engine might work but I know it takes a totally different camshaft profile that is only available on the ASET cams.

I had a delivery day recently that didn’t go as smoothly as I expected, and my tail lift ended up being the main problem. The morning started normal. My truck liftgate was working fine with lighter loads and I didn’t think much of it. Everything felt routine until I got to one of my heavier stops. That’s when I noticed something was off. The tail lift would still run, the pump was clearly working, but as soon as I put any real weight on it, the power just wasn’t there. It would slow down a lot or struggle to lift the pallet properly. Empty it still moved, but under load it felt like it was fighting itself. At first I thought maybe I had pushed it a bit too far with the weight, so I tried to adjust and split the load. But even with lighter sections, the liftgate was clearly weaker than normal. That’s when it started to get stressful because I still had multiple stops left and I couldn’t afford to fully break down on site. I ended up changing my whole loading approach just to get through the day. Smaller lifts, more trips, slower pace, just trying to keep everything safe and avoid making the situation worse. What stuck with me was how quickly a “small weakness” in the liftgate turned into a real operational problem during work. It didn’t completely fail, but it definitely wasn’t reliable under pressure. I managed to finish the route, but it was one of those days where you start paying a lot more attention to your equipment afterwards.

That's a Western R if I ever saw one. Long hood, straight aluminum frame rails, DD power. Too bad the frame is shot. Couldn't have been many with 6-71's in them.

Great points, thank you for the replies. I’m going to get new drive lines done. It looked a bit sketchy so I had to ask. I’ll feel more comfortable extending the drive shaft. Thanks

You know the body is a really good shape on that thing but the nose doesn’t look right to me. It looks like a Straight R 700 nose

Hello All, I came down the hill yesterday loaded and was not impressed, the truck ran great, lots of torque, climbing with the 18 speed is a dream but going down hill is the problem, no engine brake. I have read all the articles written on here and other places that i could find but i am not completely satisfied with the answers when it comes to the Jacob’s performance or converting the E7 to the Power Leash. I already have a set of 690 Jacob’s that have been updated and i am willing to purchase a set of Power Leash brakes to see if can be done. I would like to know the thoughts of the knowledgeable pros on this site and settle this debate and document this process.

Possibly PAI? 2007 emissions is pretty old he may be right!

RL700L !!!! don't(didn't) make um much better then that, little fluff and buff ; nice chrome stack. OK won't discuss it's not 100per cent Mack. LOL put a 865/866 in it.

i didnt see a city...bob

good points(as always) by GW ; 4 in inside yoke sounds ok BUT should the rears drop ; that 4 now becomes 2 or less . I recently did a transmission change= over on a IH ,, a real cramp!! 6 plus 2 to an 8LL. total driveshaft change over /rebuilt.

Hello everyone. I have been looking at trucks with the MP7 that has no emissions and a Mack parts guy tried talking me out of it due to the egr coolers leaking on these engines . He said the egr coolers are obsolete and no longer available from Mack. He also said the turbos are very expensive as well as other parts. Where could a egr cooler be sourced if needed?

Gess it's only my thoughts ::BUT take away their keys and proper alcohol; do they know where they slept, for me (only) a sleeping bag on God's ground works, small tent in Maine with sleeping bag next to a couple trees so moose wouldn't walk over you at night total heavenly.

can't see the city;; there are two "mountains" blocking the view!!

I guess sleeping quarters is my issue.. if i had a few campers in the yard, it would be great, we would be totaly fenced in so that we couldnt get out and terrorize the neighborhood.. 😁

and it would be /Can still be an HONOR to be part of such a gathering. why in a house large enough ??? i like the idea of open door garage and "find a 5 gal pail to park your ass"" ;; have a drink and find some food. NO politics ;BS ; foods friends and Mack conversation.!! now I have a positive to look forward too (but soon).

total agree. the 15 (615/ R615 etc usually designated a V8). not updated on the B's having Cummins = still having a B6-??? Cummins on a number of occasions brought the model to a B7????. back then little attention was paid to the model designation . it was a B / R / U / whatever. attention to the unit and drivetrain NOT what specific model it was called.

If I had the house large enough to host a get together. I promise you guys,, I would have this place stocked up and the food would be too much to Bare.. I would be blessed to host you Guys.. 🍻🥰

don't feel bad when I inform You that I will be in line IN FRONT OF YOU ..

We would be pissing ourselves out here to see prices like that… bob

But I was coming out of Bozeman one night heading down towards Salt Lake City and I stopped in like a little tiny restaurant just outside of Yellowstone that was open late. Got to talk to some dog sled guys that were training there that was pretty cool and they were pretty cool that’s the one and only time I’ve ever got to talk to dog sledders and of course it was snowing out

Or the chick for that matter, ha ha

And yes, I would definitely spend some time with that chick. I don’t think the boss would agree.
