ones green other is red ;;; put some lights on both and your all set for Christmas in the Neiborhood. then with a cup of coffee (or other) sit and stare at both while you ponder the situation.

that style brake chamber has a o-ring/ seal with a felt wiper inside. when the brakes start acting up first check is the small 5/8th dia vent on mounting face of can. tiny small holes clog faster than ---- fill in the blank

seems like temptation never quits LOL . now that's close by.

Not a maxi can ;; old style brake chamber only unit has a hand brake correct. looks like a drum up on drive line by trans. that style can has a ring of screw driver style bolts around it 6-maybe 8. use to be rebuildable . some B 's had a maxi with 1/2 in rod going to brakes . chamber was mounted in the frame

what part of Mass;; Im in CT .

standard single axle set up . don't think qualifies as camel -back .

when the air assist starts acting up like not so smooth , the cyl on tie rod usually develops a groove mid way. wedge brakes are like everything else;; great when working right: real pain in a-- when time for repair/ replace. have changed a couple from wedge to cam. most times owner was better off finding another donor. swapping entire assemblies.
-
now if they were B models ; the only wires in the frame rails that could /would short out would be for the TWO tail lights. first seeing a western that had low level sensors for the rear ends was really some thing back then. -
did it again guess;; went off topic. JOJO , how long did it take to figure that reply' i'm all out of likes again. i keep reading the reply : you know i can't afford alot of laughter , start coughing. this case it's worth it. wife thinks i m insane (still).

NOW HOW DID YOU GET PERMISSION TO TAKE MY WIFE'S PLACE AND BREAK MY BA-LS lol😂
-
I don't think the highly respected and HONORED WWII veterans can understand this post AND THEY WERE CODE TALKERS . just sayin
-
any positive updates ;; new donor or did time allow for removal of second head? be interesting to see how active the rodents were
-
you are kidding ! right.an ABS light (system issue) will derate an engine? that abs crap FIRST came out == yes i was there then also.LOL no one knew the system and drivers didn't like seeing the light so tape was put over it. the engine still ran as expected. what happens if a driver farts in the cab;; does the computer sense excess gas in cab area and derate engine !!
-
Oh ; the benefits of 1/25 scale= no computers or government involvement . the wiring and air/ hyd lines are a challenge at times. LOL
-
it's here now. most won't know what a paper log book is ; scanners on the highway tell weight stations everything (almost) they want to know of a vehicle as it passes under . how many post here ask "is the system on delete? I don't have a clue regard to delete. bet you don't remember when computers first came around to change truck engine hp with a few buttons!!
-
so it's cats vs dogs like blue vs grey or army vs navy. may the best man win😁
-
pictures sure help in proper suggestions. that far back ;; i go with MACKS recommendations. between cab and rears is a little different . don't think it's that bad to use a loader down pressure. challenge is when that much hammering is done , you don't know how much is on the sides between two rails that will flake and stay.

Fuel Tank Vent
mechohaulic replied to h67st's topic in Antique and Classic Mack Trucks General Discussion
another angle to be considered is a tank without a vent (or2) would not only create a vacuum in the suction tank ;;like those ridicules new style fuel cans ; but with out a vent (or2) the returning unused fuel from an engine which is very warm would create pressure in the return tank and bottle neck an engine,or in days of ole when running a cummins with restricted fuel return :: horsepower increased😃LOL if you didn't have access to a different fuel button. -
any info on this unit:: dump truck/ tractor: daily runner ? separation over rears ; between rears /cab? only reason for asking is for figuring proper repair. I wouldn't go toooo much with the heat ,wrong area of frame could possibly lead to cracking after. that far a separation on a daily runner may lean toward frame rail replace . depends on your access to tools .

a turbo adds hp by ramming more air into the cyls . an intercooler is just what it says, cools the air going into cyl. cooler the air better the hp. not to be quoted (memory fails often). rough numbers for compressed air out of turbo in 300 degree range after passing through an intercooler air is in the 200 degree range going into cyl. back then the hoses on a turbo engine were same. after intercoolers showed up so did the red (hot air) and blue(cooler air) hoses on pipe connection came around.

donor used at a wash plant would have more hrs then miles possibly. with it running, open oil filler check for blow by.

Fuel Tank Vent
mechohaulic replied to h67st's topic in Antique and Classic Mack Trucks General Discussion
In simple times a vent was nothing more than 1/4 in COPPER tubing off a 90degree fitting out few inches and had a loop . gone is the copper tubing and simple design. -
ENDT 673 in cold weather
mechohaulic replied to skydawg's topic in Antique and Classic Mack Trucks General Discussion
my diesel hino had a block heater ; plugging it in night before gets expensive . I made up a small board with HD timer and longer extension cord. still have it .(timer not the hino). set it for 2-4 hrs before i would be leaving next AM . worked mint. so was the truck. -
Fuel Tank Vent
mechohaulic replied to h67st's topic in Antique and Classic Mack Trucks General Discussion
good vents with the check ball actually have duel purpose. not only keep crap out but also if the fuel expands ; starts out the vent it will close the vent stopping fuel from leaking. at $6.00 plus don't splill a drop. or go the red neck cheapo valve 90 degree fitting with hose attached. parked on a slant and all the fuel runs over to low tank on down the road. hello EPA -
ENDT 673 in cold weather
mechohaulic replied to skydawg's topic in Antique and Classic Mack Trucks General Discussion
for sure the in-lines work; just a lot slower. like you said= plug it in night before. another thought on the in lines;; don't go and buy a cheaper one not having a circulating pump. location is also critical on in lines. heat (hot water ) rises . thats the purpose of in lines with built in pumps to help move the water .common practice was to install in the cab heater line. if heater was in off position water didn't move tooo fast.
