    don't know if this is of interest to anyone; found on auctionzip. has nothing to do we me; hopefully passing on worthwhile info. jan 1 2022 Densmore auctions in madison OH shows a '64 B model with apparently many parts in boxes. i'm in CT renting with no place to put it.LOL . auctionzip for me is toys now not the real ones anymore.

    with many text on the forum,added info helps. why were the brakes changed in the first place. type of brakes (shoes-disc), were the ones taken off worn. if the truck had poor responding brakes before the change and still has poor response possibly your brake valve is the problem.
  3. mechohaulic
    the fact your doing brakes; hopefully you know how. by chance when you said adjusted them did you back off the adjuster or tighten them

    being a '69 the air system is fairly simple. a hole in compressor piston would also mean one slow building air system. other then draining coolant system , to pull compressor head isn't the worse project. if it's pumping oil into air tanks , you might consider changing it anyway.

    take the discharge line off the compressor , lessening the compressor head pressure . run engine see if there's a difference in back pressure on oil fill. i would go with piston rings. not knowing engine history :hrs, mileage etc. have seen air compressors put pressure in pan ; not common. the pressure build up should lessen when air governor shuts air compressor off if it were the air compressor

    gold maxidynes were seen on the road mid/late '60's. many of which may have been "prototypes" for testing in the field. the '72 date was when enough test were completed to qualify the set up for full use. the 866 V-8 was on the road yrs before public purchase. waterbury mack in ct had a FL700 with 866 given to scovill mfg for them to run . engine torn down and inspected ; put back together a number of times. as written in previous text . gold maxi/ silver thermo.

    on the east coast, fontaine were quite common . of the 50-60 wheels i installed while at waterbury mack; most were fontaine. as with everything, the wheels were made cheaper with time..no more solid 2 in. cross pins; separate short pins sitting in rubber mounts. alot of holland wheels were put on new trucks. i wouldn't junk that wheel .

    I've been checking ATIM , seems a number of items are out of stock. possibly the virus crap is having shortages in all areas. the DM 800 kit is the donor. that RD is looking great so far. didn't think they had 4 latches on each side. the fun part to scratch building is you do it the way you like. building the chassis you have so far with the DM800 running gear should nail it. R model cab /interior will fill in the cab end . the DM800 mixer in my profile was adapted to resemble the real one of days gone by. i've been model building since the '60-70's.

    it's a "Johnny Cash" :: I got it one piece at a time RV

    Does your truck have the brackets on the seat to fasten seat belts? short strap from cab frame to seat then attaching seat belts mount to seat. i know in prospect, located at the late Dom Moffo SR shop there is an R- model in the back. don't know the story behind it. I heard the entire yard was sold, so i can't speak of the availability of any parts. hate to see that truck or any truck sit in the weather and rust.

    who would have known "back in the day" we should have saved everything! can still remember the day watching the janitor throwing out large box of vehicle literature. i saved what i liked ;B81/ DMM etc. tried to get the dealership to upgrade the wrecker (a '57 diamond T). fleet of single axle B75's with quads came in; they wouldn't go for one. to have one today. even the bulldog magazine : i had a pile, can only keep so much when you move. i must have seen Mr. Hansen publication ; can't remember.
  12. mechohaulic
    Mr Hansen was the man in charge while I was employed at Mack ; can't remember seeing the publication. does it have a date
  13. mechohaulic
    have you gotten the wheels off ?????
  14. mechohaulic
    top plunger works, i would squirt some air tool oil in the ports . new /old stock should be just as safe. shelf item not in open box subject to dirt and dust ?? . there's not alot in the valve ; o-rings/ plunger plates (flat rubber)
  15. mechohaulic
    another wild shot go on the internet ;possibly youtube will have some one removing same setup . at least you will have an idea what's involved. the wedge set up like most other things are great when they work. have taken a number of wedge set ups off and changed over to slack/cam set ups.wasn't my $$$$. most change-overs mean replacing axle/banjo .
  16. mechohaulic
    if you can't find the adjusting screw (inside the wheel), a cheater way is to disconnect the air lines, take a chisel loosen the lock ring holding the can to backing plate and unscrew the can assembly. the removal of the can and inner rollers may allow the shoes to retract enough to remove the drum

    just watched the video, he used a hammer for indicating, same as using a block of wood or spray can ;case someone is confused about me writing the text above with block of wood etc for straightening wheel. we have all talked about the install process ; no one mentioned the danger of taking the wedges off. once saw a person come close to injury kneeling in front of the tire after taking the nuts off and hitting the tire to loosen the wedges. never take the nuts completely off. loosen them then stand on the side and hit the rim with sledge hammer. wedges will fly with force if nuts aren't on to stop them.

    back in the day when these trucks were brand new with daytons, how many owners hand 1 inch impact guns! it was hand work off and on. budds were common on the west coast rigs very few east side.
  19. mechohaulic
    blackdog2 62 ton concrete I-beam; did you work for blakeslee prestress ? mid 70's blakeslee rented a fleet of DM 611's from new haven truck rental. huge single axles and tandems . had 4in spacers under the 100 ton turn table fifth wheels.
  20. mechohaulic
    another skill that has been forgotten. budd wheels easy. daytons take time to be done right. no way can a dayton be done with air gun only. 3/4drive ratchet and block of wood (or spray can works-it's high enough). criss-cross by hand the tightening sequence . have seen tire casing that were out of round also. on a good day have been able to get the daytons 1/8th true. using a tall spray can, the spinning tire will show how far out of true the wheel is. good hand tight then finally tightening with air gun.

    Mr. Buck Your in new milford , do you know Albert ; owns AJP milk haulers from roxbury. he's had macks for years. hopefully i'll see your mack riding around town soon .
  22. mechohaulic
    would have to assume the brakes are backed off ? ridge on drum not holding wheel on
  23. mechohaulic
    sounds like inner bearing is stuck. my suggestion : put the outer bearing back on with nut left loose. this allows you to either put a couple of 2x4's or small bottle jacks behind the hub to pry the wheel off. some times hammer taps do the same.
  24. mechohaulic
    changing over to all oil use to mean changing seal type. leather grease seals didn't do well holding back oil. todays world (i'm 70 old school); leather seals probably don't exist. LOL.
