    i forgot to say one end of hose to your ear other end use it to follow where the noise sounds to be coming from. noise will definately get louder . the hose technic helps eliminate surrounding noise.
  2. mechohaulic
    i'll bet you didn't try the "heater hose technic" you and others will have a good laugh . take a length of heater hose ; 1 in x 2-3 ft long worked for me. i know today they make fancy stethoscopes . hose to your best ear and follow under neath till you close in on the noise. that noise isn't bad, frustrating and making me scratch my head is ::why did i say I DO twice!!!LOL

    keep in mind these questions might sound simple ; it's a challenge not being there . are you by yourself listening or are you doing the walk around while someone else does the fuel pedal/ brake application? what happens with 1200-1600 rpms and No brake pedal. trying to narrow down possiblities. went from a maybe clutch/ driveline to engine . have been there done that on site frustrations with noise or vibrations. the distant diagnostic has many more options
  4. mechohaulic
    a worn power divider will send a noise through the driveshaft tube into the trans with out causing a vibration. did you try jacking up one side ;;chock blocks and every possible safety feature. put unit in gear slowly bring up the rpms with LIGHT pressure on brake to put resistance on drive line?
  5. mechohaulic
    depending on PTO set up , as earlier stated light load less engine noise /more free float gears, heavy load more fuel== more engine noise & less backlash. if it were an engaged pto i would think there would be an over heat smell from hot pto

    also we don't know if when truck is at stand still reving up to 1200-1600. is the driver keeping his foot on clutch pedal or neutral and pedal up ?? "but doctor i don't feel good" -- what hurts---- I don't know but it hurts 😄
  7. mechohaulic
    agree 110%. see and physically hear make a better diagnostic determination. still good to try and be helpful not to mention keep the ole brain cells active...LOL i'd be interested in the PTO set ups.
  8. mechohaulic
    just a thought Joey; if it were the clutch brake or pilot bearing the noise would be there parked and running 1600 rpm's . should'nt make a difference with load weight ?? that's why i thought more toward gears moving or PTO malfunction. ????
  9. mechohaulic
    if it were the older style spicer clutch they would clatter while you stepped on pedal. no noise parked with 1600 rpms would indicate trans counter shafts aren't moving 100%. under light load ( possibly even bob-tail) has light load on drive train allowing for free style back lash. under HD load the drivetrain is tight under load ; no back lash. far as the PTO question; ! -1 == one of them not engaged ( that was brought up in another text), 2== have you checked back-lash in the PTO's? if they or at least one is a side mount under light load moving the drive gear would be turning. rear mount hyd shouldn't be that noisy.

    picture looks to show a winch . does this unit have a PTO?
  11. mechohaulic
    error===2 is not supply; 2 is delivery.
  12. mechohaulic
    forgot the simple part (i'm old).before taking any lines off just work the trolley to see if it was partially pulled.if it wasn't THEN take off the line check for air going through.also if there was another air back feed on the treddle valve the valve SHOULD have an air leak out the bottom (exhaust port ).
  13. mechohaulic
    might be alot easier to take the feed line off the trolley in cab then lines off brake valve. trolley three lines 1-supply(constant air) 2-supply( air to shuttle valve on brake pedal ). 3 exhaust port (out to fire wall.
  14. mechohaulic
    if the unit has a trolley valve and truck is in bob=tail mode, the tractor protection valve won't effect brake operation, with the shuttle valve working the slightest pressure on trolley will STILL activate the brake lights but NOT the brakes.

    i really like the looks of a clean, neat shop. you built a real mack quicker then it took me to build a 1/25 scale mack. LOL. truck is coming along great. hopefully this virus stuff will lighten up and shows will start again. possibly we can make it from CT to a VT show this summer and see the truck.
  16. mechohaulic
    i wouldn't go as far as to call it a dumb question. many time when in search of a problem, people go for the technical side and over look the simple. how many times on the news there's a story of someone on the highway with a body hitting an overpass due to a PTO engaged. yrs back while at mack a brand new mack dump was taken down the street to fuel up. the driver (not me) some how engaged the PTO , the raised body hit the over hang lucky no one in the fuel shack was hurt.. it does happen.

    if the housing was changed with an after market replacement, the headlight ground may have a pop-rivet to the assembly which isn't completing a good ground.
  18. mechohaulic
    as stated above sounds like ground issue. the pass side goes out possibly due to it's back feeding ground through the driver side. disconnect driver side takes away a poor ground to pass side. corrosion in plug will do it. trace the harness; might have broken/ fried wire

    cardboard/ drain pail under front corner , little spray of brake clean and brush.

    is the tag still on the door model /serial,, R611=== 673. R685 ==675 (doubt that one)

    many years ago i started putting together the first gear B61 T&T sets based on the east coast fleets, had quite a few ; Adley Express, Yellow, Wilson, ETC, still have the St Johnsbury, and Lombard.
  22. mechohaulic
    these "remember when" topics really get the brain cells going. the east coast had it's share of regional fleets:Lombard, Wilson, St. Johnsbury and an endless list of time gone by. when the topic starts with Matlack,Chemical Leman, and other major fleets no longer times have changed. being an ole Bast---- like i am LOL the gone to memory fleets list gets longer. was a major deal in the day to see the fancy yellow Monfort fleet fly through CT. don't know if they still run or not.

    made an attempt to go out to garage today to look in that "special drawer" of home-made tools. the temp will have to go above the single digit first. modern technology (silicone) has replaced all the good stuff. one of the challenges back in the day was to see a transmission put together with this new white stuff silicone and not actual gaskets.
  24. mechohaulic
    seems to me i had a HD box wrench that i heated up with a torch ; put an off set riser and bend in , cut off the open end was able to put small length of pipe on for leverage to tighten the inner bolt. before the days of silicone we put the brown tar -like permatex on the threads for sealant. sure we all have the one draw in the toolbox with custom made wrenches . problem with old age ; i look at the tools can't remember what i made them for.
  25. mechohaulic
    todays news is showing the picture and saying packages will be late. seems to me if the trailer had partial load it would have slid back rapidly and flipped the entire unit over board. full load should have kept weight on trailer . no one hurt that's the important thing.
