That was Mack's western interior. It had dogs stamped in both door panels. Think they ended that after they stopped building valueliners...Here is a pic of a panel I had re done.. I painted it black to match the western interior that I installed..

First time I saw your bcr was at the aths auburn IN show in 05'? saw that bcr badge on the cowl and had thought to myself how i never seen that model befor...great looking truck

can someone please Idendify these valves so I hook them up to the shifter correctly. I guess starting at 12 and going clockwise... Thanks

It limits full engine power. I would suspect it limits when in low low and reverse. Only?

Try posting when your standing on the ceiling? Let us know how that works out for ya...

Here is a shameless plug... Looks like I was spotted at Walcott

I like the trident better. This superliner has way to much fender and the body lines don't flow as nice. But think its better than no superliner.

That's where I saw it last year. Have not met him but think it is a cool old truck he has.

IS THAT TRUCK STILL AROUND AL?

If they stay here rotting in fields, they will be sold for scrap. If we let them go they can at least live on as they were intended to be used. Even if they only live on for 5-10 more years , that says a lot about these old Mack's .... I would love to save them all but that's just not going to happen....

Yep, death trap!

I can hear that bark now from that straight stack..

I forget the history but think it was in a wreck or was rebuilt. Haven't heard about it in the last few years...

Think it was at a nwil aths Truck show ....2006 or 2007

Sounds like a death trap lol...

Maybe. Not as many low bridges so beam trailers are cheaper?

Here is what I have to offer tonight.. Starting from the top.. Rays superliner ! LT MACK Tommy's ex Greco B81 My first job in trucking. Kanzler R model. Its a Ex paulmbo truck Convoy to a truck show,al,Tom,me and johns f model. Kanzler yard Alan smith superliner, v8 powered UPS Cain trucking r model Mark mead rs700l Rat Mack.. sand.bmp

Few things here.. Power divider when "in" sends power to both axels giving you 2 axels with power at all times. When it's "out" only your rear axel has power. There is a little more to it concerning how the diff is set up and how that power is put to the road. Mack had both an automatic power divider and manual air operated power divider...both have there good and bad points. Manual let's you lock it in full time untill you unlock it. Good for when you think you may need it, bad for when you didn't think you needed it and get stuck because you didn't lock in. Macks automatic power divider will kick in and out as it sees needed. The down side was you never knew when it was in our out you normaly got thru the mud but if you got stuck sometimes it would disengage and you can't do anything about it....it was a great system tho... There is also a diff lock so that you can lock the diff in that axel, 100% of power is sent to both sides of that axel when it's in. When the diff lock was used with a power divider you had a solid live axel and power to the forward axel as well giving you power to 3 corners. Some trucks used in off road have 2 diff locks and a power divider giving you equal power to all 4 corners. This is great untill one wheel gets to much traction and you snap an axel,diff,driveline,.etc... So for the most part a a power divider and a diff lock is all you need so that theirs always one wheel that can slip and avoid drive line damage... Hope you can follow that..

I know the smell.. It's half burnt fuel. does it do this when engine temp is warm? Or Just after start up?

I think I remember your truck al.. Did you run with a rs700l that was black,orange and yellow 6 wheeler? think there was also a white gmc 6 wheeler that all ran with each other...

That's the same info I had heard. I had these codes put in 3-4 years ago. And it ran fine with no restriction issues....Then i did the other mods last year and have noticed the issue... I'm at about 5.4mpg all day everyday. We run hard tho and at this job mpg was never a concern. Hell back when we were sponsored by texaco havoline the rule was we coukd only fill up at a texaco or shell truck station. So the game all 5 of us truckers played on the way to and from the racetrack was who could rack up the most expensive fuel bill. Lol..... Not saying we ran at 2100rpm all day but we would run hard and suck those tanks dry and see how much we could put in me.. .part of the texaco sponsorship was that texaco covered all fuel and oil expense. That went on for almost 10 years. Hell just last week i stopped at a local gas station in fl....I put $1200 in the truck and gen tanks at one filling.. The lady behind me was in awe....lol

If I recall 2100 was max under load and the dash said to never exceed 2300. Even with the maxidynes we ran them flat foot on the hi-ways 61.5 MPH all day,every day

so looking at this again with the correct trans info but not knowing your exact RPM of the tire(a quick google search did not find info)... I got 44.5MPH here is my math... 2100x60 =126000 Rear ratio 8.24 x 498 tireRPM x .69 final =2831 2831 / 126000 = 44.5MPH again....if you can find your exact tire Rev per mile I can get it closer. but you will only gain/louse 2-3mph depending on your exact tire.

you are correct, that will help speed things up for you. I also used .78 as the overdrive in my math wich was incorrect... here is copy from www.macktrucksrus TRQ-72 TRQ-720 TRQ-7210 TRQ-7220 5HS - 0.85 0.66 0.69 0.70 5D - 1.00 0.78 0.84 0.84 5LS - 1.18 0.91 1.00 1.01 5LL - 2.52 1.95 2.12 2.13 4HS - 1.38 0.85 0.83 0.84 4D - 1.62 1.00 1.00 1.00 4LS - 1.91 1.17 1.19 1.20 4LL - 4.08 2.50 2.53 2.53 3HS - 2.22 1.49 1.45 1.47 3D - 2.60 1.79 1.75 1.76 3LS - 3.07 2.06 2.10 2.10 3LL - 6.56 4.39 4.44 4.44 2HS - 3.68 2.65 2.59 2.61 2D - 4.32 3.12 3.12 3.13 2LS - 5.09 3.66 3.73 3.74 2LL - 10.88 7.82 7.91 7.92 1HS - 6.42 4.62 4.51 4.55 1D - 7.53 5.45 5.45 5.45 1LS - 8.88 6.39 6.51 6.52 1LL - 18.96 13.63 13.78 13.80
