I just finished this AMT mack R model kit. I made it to look like the first truck I drove after I got my CDL. I did not fit a intercooler and a few other parts but its basicly a replica right down to the wheel base, 1988 R model (ex Palumbo construction) 300 maxidyne 2 stick 6 speed camelback with 4.17 rears

cool link !!!

The mack gearboxes I have driven that were air shift (6-7-9-12 speeds) many had a hard grind with the splitter button, harder than any fuller I have driven. Not shure why its so hard. With fullers I can flip the splitter button (foot not on the gas pedal) and it wont shift unless I tap the pedal to give the gear box some "slack" with macks if you flip that switch you need to be ready to match rpms to the gear selection. I thik the fullers have a more gentle shift? I have heard some fullers grind that hard but not often?

I think it was an option on most big engine superliner models? or it was needed for the V8s here is my bosses V8 superliner with twin air cleaners. it was delivered from mack to a dump truck dealer and fitted with some chrome. not shure if the aircleaners were added at mack or the dealer??

Nice b model pumper. thanks for the pics

I have heard that to get the XT program from a dealer you needed to have an all mack drivetrain. The visions I have seen all had off breed componets. I also heard the XT program is no longer avalible due to the EPA?

not shure if "mack red" was used on B models but i know they used it on R models. PPG makes 'Mack Red" thats what I painted my B model frame with. If you cant find a PPG dealer to help you I can get the number off my paint can. Trent

The rear end oil shoud not get over 100 deg if bobtailing empty. When I pull hils in the company truck I see 120-150 depending on the outside temps and grades. Just my.02

I think I need to get a green and red R model for my next project http://video.google.com/videoplay?docid=71...d+max&hl=en

MI is a sad state I got a speeding ticket for 58 in a 55. and they wonder why they get a bad name

The crack can be welded and should cause no issue of done correctly. Im not shure how the rookie DOT cops would feel about it but it wont fall off unless its heavely rusted thru. with no weight on it I cant see it as a issue. just keep your eyes on it after it gets welded Trent

I did as Rick said I nstalled 2 new 12V battiries and ran them to a 12V starter charging with a new altantor. My B only had one batt box so it worked out fine. If I remember this was my cost from my mack dealer the batts were $110 for both the starter was $230 and the alternator was $120 To check if its positive ground just follow the + cabel off the batt and see if it goes to the frame rail congrats and get us some pics

MY Long hood (RS700L) has the 6 cyl 285 Mack tip turbine . It has about 12"-14" between the fire wall and rear engine. Some day I would like to drop a E9 in it but for now it pulls great and cost next to nothing to keep it running. Someone correct me but are the 700 hoods 12" longer than R models??/ always wondered how much longer they were?

this is a little off topic Rob..are you going to keep the Cat engine in the truck? I thought this was your R12 project?? have a good one

thats great news, Thanks again Barry and Watts mack for giving us this great webpage!!! Trent

Thats intresting 3P. when will the news be released? I have been meaning to say thanks for taking the time to talk to us mack fans!! I think were all glad we have you here to give us first hand info from HQ... As all of us here have a deep love for these old dogs. On the otherhand I will have to agree with HK that it makes alot of us worried about Volvos ownership of Mack. Just like you said someone halfway across the pond can make decisions on a truck line that they have no past history with.. I hope you can voice the opinions of die hard mack owners to HQ for us.. I think the new Mack/Volvo engines will be just as good as any other mfg but I do worry about the cab and drivetrain options. just my .02 Trent

Ditto....my RS had bad turning also. When i installed the powere steering box I cranked the stops back and it turns like a dream. If you have flotation tires and or a longer frame it seams the factory makes turning angels less to save wear on the truck.

you know your trucks if you under stand 75% of that lingo.. good find LOL. I didnet think there was that many CB slang words out there

My friend has 2 lat 80s ? Macks with the 8 stud hole rims. His mechanic hates them. and to make it worse you need a few extra spare rims that will only fit those trucks.

That might be true WV but I find myself always explaining to the Dealership parts counter guys what a 2 valve is or what a tip turbine fan does LOL I hope Mack keeps stocking 2V parts or aftermarket venders continue too because I dont plan to change my 30 year old engine anytime soon.!!!!

Cant say where to look for the trans numbers but it sounds like you have a overdrive 13 speed. if your truck had a top gear direct transmission with 4.17 rears your top speed at a governed 1800RPM would put you at about 50-52 MPH. even if they were 3.87 rears that would make it around 60-62 @1800. You would need high 2.xx or low 3xx rear ratios to hit 70 MPH. most trucks I have seen dont often come with that low of a ratio...that i know of... Sounds like that dog can run!!!

tell us it was a one shot deal gettin in the dock

hows your back feeling Tim??? tuff trucks they were.. and still are!
