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

I keep looking at that red DMM in this post; can't add another chassis to my "assembly line "right now-1/25th scale. 70 ton beam trailer waiting . have two DM800's in progress. waiting on 10 tires 11:00x 24's . have the parts for a DM600 DMM. springs around the corner and lawns need attention.

Darn do I appreciate this forum. woke up the brain cells Mark T . now i remember the set up. 11/2 angle iron that went inside the gusset on the fuel tank brackets and had spring keeping cross bracket "tight" yet flexible for frame twist. spring went missing the cross bar was bolted tight to tank brackets resulting in worn alum brackets or cracked cross brace leading to fuel line holding angle iron off road. cross line attached to spring caps was good since not as much flex in that area.

one fine looking DM: wait a minute they all are!! 😁

would new rules and regulations come in to effect todays world ?? . cross-over lines on bottom subject to road debris ,which is why modern day units have top draw. cross hose of days gone by were usually #8 or 10 aeroquipt hose clamped to a 1 1/2 angle iron secured to tank brackets with shut offs on both side as 70 mack stated. I'd run the cross line inside a round pipe or tubing to protect it from road debris and weathering. clamping method on tank brackets has to be HD yet allow for frame twist and turn. have seen many a clamp bracket broken with cross line holding support off the road.

whole video was amazing . totally impressed with the welding. haven't seen a weld where the flux curls up like a scorpion tail in years. wonder what else goes on there not being shown? LOL . don't think inner frame rails were tensile steel watching the small drill go through.

intercooler/ tip turbine fan on black one shows a repower ;; 300 plus?? can bring a tear or two to your eye seeing history and beauty being disregarded so many times.

larger brake shoes a positive on vehicles especially dumps . back to original question of air consumption per brake application; based on everything written , i would go with a third tank or larger if room is there. shouldn't have low air buzzer with normal stopping every time. did a reread . this air drop is with engine off not driving. its seems ok then. doesn't state air loss when running. have a great day😄
