    the yoke dirt seals are in the same category as brake drum dust covers. one app they keep out stones; another they hold too much heat in. as mentioned yoke seals have pos/neg depending on app. yoke is being removed for seal replacement, take the dirt seal off if needed don't cut .

    there were many good things being involved in trucks and HD equiptment then. i 'm reading the post of E7 shutting down ; goes back to what i said about the simpler mechanical operation back then.

    you sure know how to make a guy feel old LOL . i was wrench pushing on the day of your birth. 😁😁 each generation guess sees changes . unfortunately the coming changes don't seem positive. remember trucks were way simpler then. there's more wires in one new "junk" then 5-6 B models had. i truly enjoy reading these forums ; just find it difficult to see how the trucks have become like cars with all the electronics. most accessories were able to be in house rebuilds. injection pumps could be tinkered with on limited scale. when factory stated a MB fire truck couldn't have a jake brake, little tinkering had one ,, NO vin number or computer needed.

    way back in the day, most customers didn't need to even put the part on a counter. walk in tell the counter guy what you want for what truck he walked back and returned with the RIGHT part. ask for brake blocks ( use to reline your own), counter guy might ask what grit you want. beyond different today.

    now this topic is waking some dormant brain cells. air clutches use to have basically two treddle pedals on the floor. older UPS F models didn't have a clutch pedal ; treddle pedal for clutch. think i have to confer with another source ;;; hey jack jack daniels .. LOL

    auto slacks first came out , it was critical to have all matching. is it not necessary now? the slacks had a color coded tye wrap . miss match might have one adjusting faster than another. replaced one last week on trailer suspension = couldn't find a color code. correct spline and ctr distance.

    I all too well remember the days of the extended pipe on a breaker bar; every morning i wake up as a matter of fact. my thoughts of the video :1 -no never seize on the bolts on install;2- not even an impact socket on torque multiplier 3- no gloves or back brace; without a doubt a job for pros

    if i'm seeing correctly, the picture is of the rear/rear. not seeing a dif lock housing, shouldn't have air in the rear/rear.

    after clean up, drop the drive shaft , remove hold down bolt , take off the thick "flat washer" replace the hold down bolt leaving very small gap between yoke and bolt. no puller available I kept the excess threaded shaft from brake cans and made pullers or this case a pusher . using fine thread nut or two welded together. heavy flat plate with 4 holes bolt plate to yoke, 5/8 hole in center of plate with threaded rod through. threaded rod pushes against the hold down bolt. i always had the yoke pullers ;;just case ones not there. seal removers saved alot of time also. no need to pull the cover, unless worn parts show.

    i would recommend checking up/down end play (slop) before taking things apart.you can have better idea if it's just bad seal or worn internal parts. second thing ;; cleanliness is Godlyness . clean completely around yoke before attempted removal.won't do any good having the dirt in the bearings. never know i've seen yokes slide off with slight "tapping".

    stated he greased it before =no problem, maybe last grease job was in warm summer weather with a different tube of grease. just sayin, air assist set up doesn't have the return pressure as manual . can't be totally messed up if he moved linkage by hand;; afterwards felt the pushing pressure .

    # 1- a 2021 with 22K is there warranty still there? #2 - as you stated a ok till grease job; what did you use for grease based on the temp in chicago ? wrong heavy grease causing the throw out to drag .

    Based on Your post, is it possible to connect with a museum type organization that can hold/ display this truck till many details You must have can be put in order. I don't think anyone on this forum would want to see any negative happen to You or the vehicle. scammers are always on the prowl for victims. as you stated, your knowledge is limited in terms of the truck with sentiment / emotion making a sell way more difficult. if it were put on display, you can see it and others will appreciate it . then when the moment is right (never actually) it can be sold to the proper new owner.

    Also Sorry for Your loss. i wouldn't want to be in your position, TJC is correct in his statement. value is what someone is willing to pay. when an item has personal ,emotional sentiment how can a dollar value seem fair. after my Father passed and the "clean up" started, a $10.00 item was worth $$$$.yet reality it value was $5.00. tough call for many who have to go through it.

    the red gauge is cycling due to the air leak. far as the vent leak i'll take a shot at the solenoid is malfunctioning . not to knowledgeable on the new truck systems. when shut off the electrical system for ac should be off; fan still works, i'd say system live and shouldn't be. to cycle the system must be large leak.

    updates are always a positive. one thing i've noticed on this site is with so much helpful information being shared ; rarely see updated messages letting the responders know results of their help.
  18. mechohaulic
    breaking ring wasn't really the issue ; melting pistons was
  19. mechohaulic
    more detail sure does make a difference on diagnostic ideas. Thank you for update. that's sure is alot of $$$$$ into that engine.

    new generation can't use a tuna can, new cans are easy open only on one end. have to find an app for instructions on removal of opposite end.hopfully instructions say empty can first. it's a mack might be better to use a dog food can!!LOL

    to break after 24k possible mechanical failure to break again after 3k ; install failure. were new rings put in second time or did someone pick the "best of the old" and reinstall. obvious when rings break ;; compression loss, oil blowby etc, who/ why broken rings determined .
  22. mechohaulic
    where did he go ??? we are waiting for answers
  23. mechohaulic
    we are on the same page on this one. i was writing as you were posting. what was being used for a ring compressor; not granny's tuna fish can
  24. mechohaulic
    another situation not being there to see / know all the facts. what type of truck are we dealing with;; older fire truck with only 24k miles . older road truck having a rebuild== why was it rebuilt ?WHO did the work,what parts were reused? etc... not degrading anyones work, just don't know what we are up against.. I like the part " any OLD mechanics" . YA someones looking for me 😀LOL
  25. mechohaulic
    are you saying the engine was done and rings broke 24k miles later , rings replaced again then broke after 27k (51k miles)or broke again after 3k mile , total engine miles 27k since rebuild?
