    while at the Mack dealership, I mounted a 24 in fixed 5th wheel on a brand new R685st. shortly after it came back in for a new 24in sliding 5th wheel . not long after it came back and I mounted the one and only 48in slider ever done . seems the oil company moved a short pup trailer once a month; not enough to justify another tractor. in furthest rear position the 5th wheel ears hung over truck frame rails. actually saw it going down the highway once. tractor almost as long as trailer.

    how bad was damage on the spun a bearing engine? repair to 350 with engine brake not a more feasible idea VS change-over to a 300 possibly unable to have engine brake ??? repair a bearing spin instead of camshaft change.

    10-4 on the reel to reel. age factor takes place when a cassette (picture) is new compared to the "modern" 8 track which was great. LOL . almost think my first vehicle had stone wheels and hole in floor to use your feet to make it move.

    would you believe TOOOOO old to remember . I remember doing it can,t remember why. that's OLD.

    early dyna versions the exhaust valve was extremely loose until it was brought up to TDC . is it possible to know internal components by removing valve covers / checking valves ???

    if the oil was being diluted; would that not lower oil pressure ? more before changing exhaust sound. oil school test (before high -tech heat sensor guns) was the white/ yellow crayon on each exhaust port . check which melted ; changed color // which did not. or the Polack way ::: put your finger on each cyl.🥵

    not sure of the internal changes on '78 engine. based on comment " engine sounds as if dynatard was working on #1 cylinder, to me that would indicate a dyna solenoid stuck . any other situation such as loose valve adjustment would give a tapping sound. design changes in exhaust solenoid must have taken place since the valve covers no longer have expanded housing over exhaust. is it possible for solenoid to collapse? when adjusting early dyna's each cyl had to be adjusted individually when on TDC, when brought up to number #1 how are the adjustments???

    the new style cabs'-R-_-U--_-F's saved the brand more important as noted, new leadership did more. Mr . Hanson took the brand to a new future. east coast was always Mack country. unfortunately, as it is written; things change.

    perfection always takes time; usually in the end worth every minute spent. engine lookin good. I stopped and talked to Mr. Rockwell few days ago. un be knowns to me gent sitting in the group was Dom Moffos Jrs son. he's following in Dad:: Jr// Grandads /SR's"" foot steps. with the trucking.

    by '78 I would expect all the exhaust push rods have been changed to solids. by chance did you pull #1 push rods for inspection? you state it had a dynatard sound. would think that indicates it is dynatard equipt.

    based on days of old ;before all this electronic stuff I would go with a bad valve/ seat. no noise out air cleaner puts you down a different road (somewhat). valve might have small piece off or crack. from top side everything will look and adjust ok. bigger part of valve missing and you would know it. bad injector should have some type of smoke indication out exhaust if it's missing enough for noise.

    starting fluid ;; old school , didn't think that technic was allowed or used anymore. very light on the spray also. have to be cautious suggesting that type of test in todays world. too much or spray hitting hot exhaust will change purpose of test and fire extinguish test will take place. or inventory check on first aid kit.

    this is the tool of which i mentioned. wasn't too sure of the switch showed . my day most were on brake pedal valve. another positive moment old school meets new school. is that were the title intermediate school came from

    side with magnetic plug really isn't for filling. inside there is a troth which catches oil to bring up foreign objects. that's main reason you had challenge to use as filler hole. opposite side is full open to fill.

    defiantly isolate whether the problem is in tractor or trailer first. my day a test light was used ; now it a meter used. there is a tool which plugs in to light cord which will show what works. makes life easier when you sit in cab with light cord check each application. could be broken wire in trailer. do brake lights work on tractor?? not sure of wiring on "new "trucks. is the picture a brake light switch or low air buzzer sender etc. fuses check out ok ???

    use caution with the shop air. shop set for 150 lbs , don't want someone getting hurt . those old screw together brake cans might not want that much air after sitting quite for 30 yrs . spray the clevis pins with penetrating oil . just enough air to make things move. trace the copper lines completely if pressures are low. possibly a crushed line restricting air flow. thanks fr updates. side note:: still haven't found LT mack model address

    as earlier stated, if this unit is more for show not hauling a trailer or tag along having brakes ; another option (cheap) would be plug feed line to old style TTP (top line) AT THE AIR TANK for appearance it would look good. technically with the right side plugged valve has not been doing anything now except giving unit an air leak.

    didn't see anyone mention a magnet , thought possibly this mind was slipping (again) and magnets were no longer there. thanks for the positive reassurance.
  19. mechohaulic
    if it's getting "an oil change (trans fluid)" did you pull the side plug and check magnet for foreign objects == they still have magnets don't they ???? never did a tipping o=ring repair. darn doesn't that have to almost stand on it's ass/??

    old post follow up. I personally would hope for peace throughout the world not only that region. for nothing more then the sake of my grandchildren and their generation.

    line left rear (loop) from trolley; line RIGHT REAR from treddle (brake) valve. the Tee fitting front middle line to right covered with autoloom goes to rear axle brake quick release valve ?? line straight out (uncovered) is line going to TTP valve left side ??? if so that's a match and makes sense now . as earlier stated plugged line would go to trailer .

    that list tired me out just reading it. yesterday was a wipe out for me. day spent working on DM800 (1/25 scale). it was the day before took it's toll on me. warmer weather : had the power broom and leave blower out cleaning yard. knees let me know -- we are not doing that again. power broom with bristle head on upside down . works well for pulling 3/8 driveway stone off grass.

    can't post my pictures; I'm part of the witness protection program. best excuse i could come up with on short notice. LOL😷

    just a thought ; if you go through the task of cleaning/ draining trans to remove cover, have a new o-ring and good RTV for reinstall. that's of course high hopes the o-rings aren't on the list of back order parts . down time of unit also a factor. no new oring, leak bad have to repair now ;;then good rtv to the rescue. as always :: clean is the clue.

    I do know the location of a guy who attended my auction that bought boxes of my truck stuff. will make a trip and look through what ever he still has. can't get my hopes up ; for an old style TTP valve there, won't know if I don't venture there. mentally it is a challenge : same as driving by my parents home. seeing my old stuff brings in the memories. it sucks when you were/are "married" to your profession.
