    i love my new Kenworth T880 as i am in my twilight years, but i will always have a soft spot in my heart for the Mack R-688.

    in my youth i started in a 49 International L-190.

    than moved to a Mack B-815, than a 79 DM-800. than in 85 a new 85 DM-800. i put close to 500k miles on those two DM's

    in 88 i  got a brand new R-688. and i put almost 1 million miles on 688's over the next 20 years. 

    in 09 i got a 2 year old CV-713. 

    in 2010 i switched companies after the other one went bankrupt due to the owner going to prison for bribing federal inspectors. 
    i moved into a 99 R-688. ran that one for 4 years and than back into a 05 CV713. 

    in 2016 we sold that and i went into a 2010 Kenworth T880. in 2019  we sold that and i went into a new T880. 

    last september we sold that one for $20G more than we paid for it with 75k miles on it and i moved into the new 2022 T880.

    of my over 2 million miles driven, over 1.5 million were in macks. 

    Dang; that's an impressive "profile" ::B-815 to two DM800's to R-688!! I spent too much  time wrenching  vs driving. had a B-81 dump at the farm last yr , hoping to get running. go to work one day truck gone !! WTF. owner "oh I sold it . least he could have done was wait for day I was there so I could say "good bye  " . did get quite a few hrs behind a DM-800  at part-time job. tri-axle no floatation front tires, pulling out asphalt plant scaled 84K  it was a saturday boss said get all you can plants will be closing. the fun days , had a huge coal body  came from down south .

  2. another way to build a set of install tools ; look in the scrap barrel for any bad bearings, cut the outer cage =throw out the rollers and keep inner bear piece;  . extreme caution with hitting  the harden bearing parts. installing a wear ring doesn't take a 20lb sledge; little RTV and even round the spindle tapping. stemco did make a spin within it self seal which required no install tools even tapping . I always lube the two spinning pieces before install whether C/r or stemco.

  3. was always a stemco believer ; had at one time quite an assortment of the install tools :: in the dinosaur days when each seal had it's own drive tool ; before the blue tube and changeable heads. the grit guard seals were a big improvement for keeping crap out. technology came out with the spin within itself seals (C/R). bet not too many remember the stemco seals when the wrap was actually leather ?? based on picture; i go with a improper install with a hammer. in hardship cases , I have used the inner bearing for ring install, carefully tapping inner race with flat punch, huge metal washer found in the HD Mack rear wheels also worked for a tapping spacer. close tolerance on spindle / thick enough to tap on.

    My '77 R600 had the ESI and l think it was 34qts in the pan. l remember the oil pan was big enough to bath a small kid. lol    .....Hippy

    some where along the way the 3 spin on set up with large oil  pan was 51 qts  ??? possibly that 51 was total capacity including filters. unofficially there was a problem with the large pans  developing cracks , something with the manufacturing /casting process. brazing didn't work for repairs.

  6. not only looked cool but technically it helped engine run cooler. and driver didn't mind a cooler cab inside . keep in mind this was the day of mechanical common sense not computer modules  shutting down a unit due to temp  fluctuation ;; LOL 

  7. between the pencil and pto shaft . the small shaft pushed in is the aux shaft I was referring to. center is 1/2-5/8th thread.  when rear cover is in place, aux shaft in present position. when installing a rear pto that shaft has to be turned 180 degrees  : actually sits inside the pto housing. I would assume that pto is being mounted on top right?

    THANK YOU  ;Macks for photo. 

  8. no idea how much on a positive I feel now. most of night staring at ceiling trying to remember (yes i did). duel reasons =1- feared I misinformed someone;;2- constantly concerned of mind loss. cover closest is one I remember. by chance is there a picture of back side of transmission showing the aux idler shaft which had to be turned 180 for a pto to be installed ?

    That is before my time Mech..  I started out on X107 and 1070B.. then 200 series, and then 300 series. Bearing race is in the bearing cover, so pulling the cover allows the counter shaft to drop a little.. 

     I can understand now why you made the comments of the countershaft dropping. makes much sense . which is reason i said DON'T DROP OUT of conversation.  I actually confused the topic not realizing a change over in countershaft bearing set up. I didn't remember having to take side cover off. can see why now it would be done.

    I'm lost, Mech... I'm thinkin about 107"s  are you talking TRD72's and such..  ??  I may need to back out, so I dont post wrong info..  

    think I know where  confusion came to be. memory serves correctly; at 2am today staring at ceiling ;;the EARLY 6 speeds had roller bearing for three counter shafts  , not bearing/ race combo .when removing lower rear cover for PTO installation there wasn't a bearing race in cover. just a "flat" aluminum cover. hardest part to pto install was turning small idler shaft. never had a situation with dropping countershaft and misaligning timing. spent many hrs in machine shop at Mack and watched the man I considered to be the Master builder. He always prefaced the importance of the timing. a rear 6 speed pto install was done in short amount of time  then. the pto went up against bearing /held it in place.
