there is also the air cleaner set up (winter/summer) that has the cable control which closes the door on air cleaner to allow engine cabin air :warmer air to be pulled into engine less from air cleaner tube (outside air).

back then going to work every day I passed a R700L ( RS700 or RL700 don't remember). stopped a number of times and took pictures. will look have high doubts I have them any more.

I can't remember any other AC unit other than kysor back in the day. AC in pictures looks a little wider and lower than kysor. not saying kysor didn't have other models. when a Mack western showed up on the east coast in the day; everyone stopped and stood at attention (sorta). racking memory banks , the RS700L was a west coast designation . R-r model / S-steel frame rails / 700- series/ L- western issue ?? not sure on that one. RL700L = R model with (L) aluminum rails 700 series . gray wrap around dash? I was at Mack '69=='75 . have to agree with guess on yr of wrap dash; mid '70's. I can't remember exact. for the RS700 model in progress (which is looking fantastic from a truck modelers point of view; I would take the DM800 kysor and cut it low and wider.

Guess the Diamond T or R model won't be getting a sleeper. LOL: Dave in CT

what do these NEW engines use for fuel shutoff? obviously it's not mechanical ; electronic controlled solenoid over fuel? others like cummins have(had) the fuel solenoid opens and closes for fuel. possible fuel pressure some where greater than solenoid can over ride ? reading all responses regarding wiring , don't see where bad wires would make a difference hot or cold .a relay or module ; yes . hope this topic has positive results ; i'm always eager to learn new.

opinion from an ole man based on simpler times. !-engine turns over =fuel pressure at line lower; is the engine turning over just as fast when hot as it does when it first started cold?? should the engine have a "weak "starter when hot turns engine over slower, results COULD be lower fuel pressure at injector lines. common sense would notice slower turning engine ; but common sense would also say :: DON'T hook a chain to front axle! just sayin. trying to cover all bases.

can't tell by the pictures if that's a silver or gold dog on hood and doors. front headlight insert has cut out for block heater. all in due time. hopefully we will see the specs. model/ serial #

that might be a good title to a new topic;;; if you found the first truck you ever drove , what was it .

fantastic looking truck and story. that's better then finding an old girlfriend. at least when that truck "barks" it puts a big smile on your face. 😁

with the manifold (has tooo big a hole ) still in place , use a slack adjuster bushing or bushing similar to fit in manifold hole . using a drill which fits snug in the bushing you install. this gives you a better chance of close center on broken stud. a good drill will center "mark " stud. then with a left-hand drill, drill through the stud. i have gotten away from using smaller pilot drills simply due to fact have had toooo many pilot drills break;; now you have to get broken drill out. have NOT found a drill bit that will drill out a broken drill bit. that includes the carbide tip drills used for drilling the many 5th wheels installed. also using the step-down drilling process a drill bit is using the outer edge of the drill not the entire cutting edge . each project is different. in terms of your project with manifold still installed can't see if any of the stud is sticking out beyond the head. if can't be drilled out then manifold removal and welder to rescue .

a good set of left=hand drill bits many times make the job easier. have seen people use right hand drill bit on broken stud which wasn't that tight. drilling to use easy-out will tighten broken stud. left-hand on occasion helps loosen. your situation, i'd let it go unless exhaust leak starts. extended exhaust leaking will act like plasma cutter and will channel a grove in manifold. drill center of broken stud / spray penetrating oil and run it engine heat with penetrating oil might help the cause.

when you build something yourself: car/truck etc there's more pride and satisfaction to the build. a car show in town had many owners who it was obvious knew little of their vehicles , just wrote out a big check to some one else. I had the great pleasure of working with another mechanic yrs back who owned a steel willy coupe = not a plastic rep . he built the eng / and complete car. I asked once why he didn't take his car to the town car show. his reply" they don't know anything about their cars just write a check then sit on a lawn chair.

I'm always (most time ) looking for parts inventory (1/25th scale). don't discard .

if you really pay attention to why " , turning the other way ;;;so they can open their pockets wider ($$$$) and "oh i missed that " just sayin

is that why vehicles considered not road worthy in these states go over seas to be run for yrs. their frame straightening technics might be different then here.

no go on the old boxes of parts :: younger generation "in charge" . the shelves that held parts of days gone by , now hold cases of filters :: most of which will never be used. different world in the trucking industry: at least where i went today. 30 + yrs ago myself and two other mechanics set up the new garage having it's own upstairs parts room. walking through it today totally sickening. boxes of stuff all over floor and worse. I questioned all the old parts :::"they must have been thrown out. " still a few OLD fan belts hanging with old Mack logo cardboard wrappers ( i should have taken them ). belts no good ; they would look great in a mechanic man cave on the wall. compressor spacer gone. there was a gasket ; I wouldn't use it so I left it.

so being a '56 it was old enough to be "at the bar ", hope it didn't have any high test then go driving!!😁😁. sorry couldn't help myself. Red and White ;;it was a Polish car .

don't want to get hopes up ; i'm going to make a couple stops today where boxes of parts are, ole #1 R model is still there: upstairs parts room has stuff.

the 4 billion $$ is a small part of wasted money. the $$ for planning , security , and i'm sure he didn't sleep in a tent. I don't know why idiot had to go to Poland to screw the Polacks up . dumb as he is ; must be smart enough not to want ending up like Kenndy, he's not going to offend the railroad.

back in the 70's I had three DM 800 models in the parts room display case at Mack. two TT and the 800 mixer. first Mack I drove was a brand new DM611 single axle . was taking it to the glass shop for window repair. I think half (or more) of the mechanics were standing outside in the yard watching this youngster trying to shift a quad, and laughing their as- off.

nice unit, color and logo. yrs back I started to acquire the first gear east coast fleets that ran B model Macks. had maybe 30-40 . all went in the 2011 auction . sad day for me .

fully agree with Mark T and 67RModel. shifting with the engine brake is a positive "if you know what your doing" and it is needed. and the ridiculous is a sure thing when as stated "level empty jaking every (unnecessary ) gear to hear the 8 in pipes Beller. put the speed shifters behind a quad ; watch how fast speed shifting takes place. LOL at least the 4in pipes would sound better then the 8 in. quess i just can't leave the 50's -60's- 70's trucking . b-models weren't 250K , didn't have 100 lights on alum bodys. lest us NOT go off topic .

removal is the easy part; wait for fun install. if it still has the nylon nut, challenge has begun. nut with lock washer will have you using words children shouldn't hear. know for a fact my fingers could no longer bend and tighten that nut any more doesn't matter which combination it has. the flat/ lock washer would be dropped many times.

some how or other this is going to include a B model and trailer ; i just know it. LOL. dining out on the trailer!!!😱

news on right now states people area of ohio train wreck experiencing severe headaches and air stinks. don't expect this country to help their own. that's wrong..
