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..

from a distance the major difference would be longer hood on 700. specs on a 700 VS 600 would have just as wide range as comparing two 600's. chassis rails, eng/trans combo. hood shows it was a V-8; changed to a 6 cylinder . will work for a local running unit. till you see door tag and vin rest will be a mystery. important thing will be price / condition / close inspection to check how change over was done. chassis model will tell what V-8 it had. one stack (Mack)or two 3 1/2 stacks (318DD).

to this day I notice many drivers using the engine brake for "speed shifting"' years back at many classes the instructors specifically stated an engine brake not mattering what manufacture should not be used for shifting. back then a major construction co made it known to its drivers : anyone caught engine brake shifting will be terminated. seems rules must have changed. company still around bigger then ever and I hear their trucks engine brake shifting. sadly they are no longer a Mack co.

the cross over fuel line set up also depended on the fuel tank configuration and model truck. square/ rectangle tanks mounted higher had the crossover line going from rear spring hanger caps ( 4x5 in cap ??) attached to a 1 1/2x2 steel channel . round tanks hung lower (most time) had the cross line tank to tank. always an exception but think about it square tanks were on construction vehicle (off high way usage) , lower round found on highway vehicles. fuel in lower mounted tanks would have to travel on up hill to go on front spring hanger set up.

when billions of $$$ are sent overseas or anywhere for that matter ; it never gets there. all the pockets filled along the way take it. why would FEMA go to a toxic chemical spill ; don't you realize they might get sick. it's high hope that miles of paperwork FEMA has to fill out first will take long enough so the danger will pass.then they can show up when the cameras are there.

i'll go out on a limb with this ; the book a great idea : my first purchase after the powerball win would be all expense trip to central location for all interested on this site for a meet and greet so we can discuss a book. i would arrange it since I worked for Mack AND coca cola ; and you thought i would go off topic. LMAO

AHH the good simple days. back then you could even take a hose and 5 gallon can to siphon fuel or gas. don't want to "drink" that sh-t today.

it's the spacer used to keep compressor head from hitting rear of injection pump. air compressor had the extended drive coupler . darn the parts I threw away. don't have the coupler ; do have the bent modified 3/4 wrench made to get the inner (pain - in- ass ) mounting nut.

And it's NOT my fault THIS TIME ! think I've been much better with off topic this yr; new yrs resolution LOL
