Sorry Bud... however,,, it is really good that you found this issue.. i say Good Job..

Im not really sure why a Mack 200 or 300 series synchro would go out early? a lot of the time, the o-rings for the range shifters are not replaced/lubed every few years.. Sometimes I think that drivers flip to 'lo' at too high of a road speed and over speed the rear tranny gears.. I have seen worn clutching teeth, which I relate too slow range shifters due to bad or dry orings.. anyway, I dont know if you have ever been inside a 200 or 300 series Mack tranny.. The synchro is large compared to Eaton or meritor.. I describe it as a 2 sides motorcycle clutch.. I believe there are 14 friction plates and 12 pressure plates, plus a thick thrust washer.. It really isnt hard to repair, but having a book for the first few times is very important.. too many steps, too just 'wing-it'... 🍻

The book is 23 years old.. I got it after finishing Tranny school for Mack.. I have 4 sets of tranny and rear end books

I knew I had the Mack in-chassis synchro book.. Here are the special tools to do the job. the ''Z'' brackets can be home made, the holding plate costs more for a machine shop to make than it is to buy one.. Good luck,, Jojo

ok..

Good find.... That is the V.E.C.U. looks like the wind shield is letting rain come in.. I think you can spray it clean with electrical contact cleaner that is 'sensor safe'..

21QB3249P174 Control Cable Genuine Mack Truck Bulldog Parts 21QB3249-P174 NOS.. I found this on EBAY.. not sure if it correct.. I typed Mack CL throttle cable, in the search bar, and a bunch of listings came up.. Jojo

I got'cha.. Pricing is SICK !! as we know all too well.. Have you looked at Raineys truck parts?

I'm guessing, Mack cant find the part # with the V.I.N. ? I used to take my dirtbike cables off and poke one end through the corner of a ziplock bag and go around a few times with elec. tape to seal the bag to the cable. Then pour a couple ounces of ATF in the bag and hang it up. ( Kinda like an I.V. bag) in a few hours, or over night,all the ATF has poured out the other end. Just an old way to keep my cables lubed.. On sorter cables I have used a drill and spun the cable. like a screw pump, i could dip it in ATF and it will pull the ATF through the sheath, and come out on the drill end. it takes a few minutes to do it this way.. Jojo

That is awesome !!!!

I dont know how you do it??? My wife would kill me just for lookin'.. and yes ... I think D's are a passing grade too.. Can I get an AMEN??!!!

You caught me!!!.. I was in Dreamland for part of that posting.. I wonder off into a world where America IS Great Again!!! and then I type my dreams, on this thread.. Guess I need a new prescription to keep me balanced...

Just a little update.. I believe i posted that A.T.&T. / Directv dropped NewsMax, and O.A.N. .... a while ago... Well,,,,, NewsMax news channel is back on the lineup.. so I guess we'll see.. Not life changing news here, just a small part of the bigger issue. The Dissolving of the effort's, to destroy US.. I hope this is a trend, and in 2024, we ACTUALLY see an HONEST VOTE..

Sidetracked -or-Not... Mech... You always make me smile... 🍻

So true Mech.. even at the end of my business last July, I was still expecting the BOX to have the same CONTENTS as it always had, only to find out,,,, nope.. and stupid stuff like seals, and gaskets... MackVo,,, or should I say,,, VoMack?? is notorious for this.. I have been impressed by after market re-build kits more than OEM kits.. (PAI/ and Maxiforce for the John Deere engines I built) Yes to opening the box to take inventory... Jojo

👍

Bob.. it's 80 degrees right now. I rode my Harley to work. Getting ready to head out on it again..

.Paul, this one is for you.. A Buddy knows I like Black Licorice.. He got this for me today.. It comes from Ingleburn NSW.. is pretty good.. 🍺

Was the starter replaced recently?

Yes sir.. I figured.. but he doesn't need them, I guess I was just trying to inform him.. at the risk of sounding like an ass.. when the question was asked about what tool is needed to be able to pull the back box, My first thought was.... This is too big of a job for someone who hasn't built one of these tranny's.. at least he has us to help him or deterre him from doing this... With respect,. jojo

I don't know,. I guess I will try again later..

I know he needs the part number for the plate that holds the counter shafts, so you can pull the rear cover in chassis.. he will also need 4,,. 'Z' brackets to hold the counter shafts so he can remove the main shaft and synchro assembly.. I will try to get pictures when I get home later..

Thanks for the update..

One more thing... Why doesnt our Govt. just shut Tik Tok off??? when russia went into ukraine they shut the whole internet off.. Why dont we protect our country???? Because,,,, those that make millions off this crap, need time to move the assets and companies to other foreign banks so they dont lose all the money... thats why...

all good.. buddy,,, its nite nite time.. I wish you well,,, Jojo
