I put a little of convoy and a little of Road Warrior into it. you know best of both worlds....

Yea its tuff keeping her clean. The paint job looks good from far but its far from good.LOL. but being a rock hauler I see little need for it to be a trailer queen. The dash came out good. Need to pit a cb back in and refinish the steering wheel. I'm thinking of fixing the cracks and repainting it white.

looking good larry. I will have to send you some "Bunny" posters for you to hang inside....I was out west last week and spotted a B model with integral sleeper. Was then wondering how your project was going?

Thanks guys. im suprised the pics came out so good.. they came from my new "smart phone". what ever that means???? Well it rained last night and washed all the concrete dust off it. I removed the odd ball steel air tank and then put on a aluminum air tank that Phil from Global truck parts sold me a few weeks back. gave her a little spray wax then took her out to get a little dirty again.

a few more

Gave the truck a quick bath and then hit the road. took some pics when I got back. felt good to stretch her legs.

looking good!. whats the plans with it now? Wondering whats it cost to ship it overseas?

think there was a post on here a few weeks back about a guy selling one or it was going to scrap? anyone recall that post?

the canadians still have good taste in trucks. even the old R models had many if the fancy options.

I dont know the exact year mack sold the last flat hood R model but Seams that 89-90 was when I stopped seeing them and the sloped hood RDs came online...the RDs were just as good and thought they looked fresh considering how old the cab is. Last RD I drove was a glider kit that had a 2v 300. one of the fastest R models I ever drove.

if your getting that much MPG with a V8... I say dont change a thing! A MH with that much of a wall would not be helping you. The golden number is 55MPH. It seams that when you go over 55MPH wind and HP become big factors for wind resistance and power needed to pull thru it. My little turned up 285 gets 5.5MPG empty or loaded. all city miles....

I bought some nos found on eBay.. they are hard to find but still out there. Might find some from a junk truck and have them related ??

yea. 4.17 would put you in the low 60 MPH depending on tires. 3.87 got you up to the 68-70 MPH mark. Most macks with the 5 speeds pulled better with 4.17s but some of the OTR guys put the 3.87 in to get the faster road speed and lower RPMs

Look behind the water pump for a stamp.....END(T) 675,676 etc... if its not there or on a tag mounted to the passenger side of the block.... your numbers you give looks like you have a E6 350hp engine. Mack changed engine notation a few times in the early 80s. the diffrence in the the thermodynes,Maxidynes,and Econodynes were turbo,injection,timing,fuel pump settings etc.... each engine had its specific torque rise and thus were suited better for certain RPM range. The thermodynes were common in B models and needed lots of gears and lots of revs to keep moving, the maxidynes came out next and changed the whole game. they were High torqe rise and only needed 5 gears to pull a load. a nice concept coming from twin sticks and low power engines. the econodynes were more intended for OTR use, they had less torque than a maxidyne but had higher HP. they were better suited for long haul. again later production years the econodynes were basicly a maxidyne but set up so save fuel and had lower Max RPM settings. thats the basics of them

congrats rob

somethings seams odd here? a direct drive trans is 1:1 ratio. put 11R22.5 tires / 4.17 diffs behind it and you will be at 62 MPH at 2100RPM this tells me that if you had a 1:1 trans with your current 3.54 diffs you should already be at 71 MPH at 2100RPM I may be wrong but I have never seen a truck trans that was slower than 1:1? not saying it was never done but... 3.54 rears are kinda fast, for example if you had a .78 OD trans (over drive trans) and the same tires and diffs you would be at 100 MPH at 2100RPM.

If the power divider is worn out it may not kick in like it should. Remember all the power divider does is put power to the other axel. when its in you have 2 wheels with power. when its out just one wheel has power. thats not to say that both wheels of the same axel will spin but as soon as one wheel gets traction it stops and then power goes to the free wheel. this is where taping the brake pedal will sometimes stop that spinning "free" wheel and transfer it back to the one that has more traction. only If the truck has a air operated diff lock. both wheels of that axel will fully lock in, other things come in to play but thats the basics Most macks I drove had a automatic power divider and thats it. alot of trucks I drove with air ride had a manual powerdivider and a difflock for one axel. this gave you 3 wheels locked in and one wheel was left free to prevent driveline damage. However some trucks can have a powerdivider, and a diff lock for both axels giving full 4 wheel locking power to the ground. any time a difflock is used it should be on soft or louse ground mostly in a straight line so not to put stress on the locked axel. hope that helps Trent

I think what your dad was telling you was that macks automatic power divider. if you were stuck and spinning the wheels or just spinning the wheels on one axel, you tap on the brake pedal to try and get the power over to a diffrent wheel/axel and hopefully if it transers the power that wheels traction will get you out. I have used that trick many of times. some times it works sometimes not. need to go easy as its abuse on the drive line.

Thats a cool Pic... the good ol days. to bad I was born a little to late to live them... However When I remmber when I first started driving. You pulled into a truck stop fueled up without paying first, sometimes a guy would come out to handel the hoses for you while I checked the oil and cleand windows. when you were done you pulled up or parked and then went in to pay. now you have to go inside 3 times. and wait behind the same 3 drivers each time. 1 go in to pay 2 go back in to turn the pump on after it shuts off because you needed more and they cant hold your card 3 go back in to get your recipt. what normaly took 10 mins now takes 1/2 hour

his contact info is in the pic of the parts manual.

Heres the short story. A fellow had emailed me shortly after I bought My RS700L in 05'. He was intrested in some detail pics of Mack western 700s I took a bunch a pics for him and we chatted about the RS/RL and the diffrences in them over the years. His intrest was to reproduce model parts for his Mack western builds. So after 5 or so years of chatting thru email I get another email a few weeks back. he Showed me some pics of the diffrent trucks he had built and the parts he had made. Saw some pics of the parts and I had to have some as I was intrested in making a model of my RS. I get home and find a card that says I have a package waiting at the Post office. Get the parts home and here they are,Pretty cool the amount of detail he puts into the kits. I dont know exactly what a kit contains as he thru in a few extra stuff for helping him but if your a model maker you may want to contact him and see what he can do for you.

What did "the 151line" mean..always wondered...

Also before you fire it off.1st crank her over with the throttle stop out until the oil gauge starts to read. Then push in the stop and when she takes off you know oil is flowing..

Trucks looking good. If you have time When you get it home can you pop that hood and get us pics of the engine and how they got it in that frame. I find it intresting how they set up the cowl and extension panels The duel head lamps look like they came from a A model KW or that aftermarket clarbian (Spelling?)hood MFG. they look diffrent for sure. not sure if I like it or not?... Glad shes home safe and sound...! Trent

My Cell phone went dead the other day. It was a hand me down from a friend from 4 years back before that I had a phone from 4-5 years when I signed the first contract with Nextel. Now I have seen all these wizzy smart phones but never cared to test them. Have many friends that use them but still I was in it for nextel direct connect service. Problem now is that my phone was dead, im on the road and the word is that Sprint is killing off Nextel in a few years and not putting out smart phones with Nextel service... Me being on the road I always had a hell of a time with Nextel service out west or 5 miles off any major interstate. more than 1/2 my friends dumped the poor nextel service for the better sprint coverage. so come today and I find that I hadent been in a phone store for over 7 years. none of them looked like my old beast of a phone.... So hear I am. old dead phone in hand and looking at all these flat screen smart phones. After 30 mins of messing with them I decided to get one. Bought a HTC evo4. I dont feel smart for buying it but have to say it does everthing I could think of that a computer does and more than I care to learn right now. as far as today went I was able to take pics and then send them to the girl back home. its kida interactive and that helps when on the road trying to communicate with work and family.Give me a few days and I will let you know what I think of it. I think I have a much better understanding why I see so many close calls on the road. Besides making a simple call, the phone has so much stuff that if your driving you cant pay attention to the road if you were fumbling with this thing!!!! thats all for now!
