That makes this an interesting "U" model . Too bad the poster never came back . Thanks for the info

Funny how he all think it would be better somewhere else . I actually had a 1970 Chev pickup from Charlotte . It was totally rust free . I thought it must be amazing to live in a place where things don't rot away from salt .

Thanks Jojo , I don't stop in very often this time of year. I see your busy helping people . BMT is lucky to have you . I still wish you could come north , lol . I don't have a good Mack mechanic . Wish I did 😀

A little more digging ......... If its a true " U659 " there was only 501 built in 1979 only . Thats it . So it could be pretty rare .

I see the poster that asked this question never came back . But I wanted to help shed a little more light on it for you . The first number 6 you got right . The 59 is the engine code . From my list from BMT , its a Cummins NHRS6B/320 . I honestly don't know what that is ,lol . Hopefully you can help in that department . You got everything else right , as far as I know . The ST at the end of the number means a little more than twin screw . The "S" means twin screw . The "T" means it was built to be a tractor .

Thanks so much for sharing your pics . As always , they are great photos . I tried to pick my favourite , but there is so many nice trucks I couldn't . lol . Thanks again

Looks great Vlad. Like the others , I love reading your adventures . Is it an R688 ?

Sorry to hear this. RIP superdog.

Looks like the dog is living a lot better life than the freightliner did . LOL Dog looks very happy and content 😀

Yes, your right . Well said

Looks great !!! Thanks for sharing your progress with us .

Thanks , but I can't take any credit for any of that info. Everything I know is from this great forum. Unfortunately , the trivial stuff I know doesn't keep trucks running . The knowledge you and others bring forward is way more important .

This is 39 Baby Macks post , copied......... On a further note, All the older dogs are supposed to be duplicates of the soap carving made by Alfred Fellows Masury in 1932. If you look closely at these dogs you will notice that they are not symmetrical. This leads one to believe that the soap carving story is true which I believe it is. If you look straight into his face you will notice that his R.H. eye is higher than his left, turn him around, look at his back hips his right one is cut down lower than his left. Look at him from both sides, notice the flat spots in the middle of the legs on both sides, wide on the right, narrow on the left. His mid section narrow in front wide in the back on the left, just the opposite on the right. Needless to say he's crooked as a copy of the carving would be. As Don stated above they changed the ears and tail in 1979. I like the way he put it, to make it more friendly. The rest of the dog stayed the same, crooked as it should be. Sometime later I was surprised and disgusted to find out that they changed it altogether and that he was no longer crooked but was indeed symmetrical. I don't know exactly when they did this but I first noticed it in the early 90's. Go look at a new one, he is indeed symmetrical. I have no idea why in the world they would do this, but the thought of some young buck noticing it was crooked and thought that it was terrible that their corporate symbol was like that comes to mind! I think before changing it they should've found out why he was the way he was and left well enough alone. It's funny, but at about the same time I found this out the Mack Co. was running an ad in the truck magazines about the "Bulldog" Wish I had one to show, but I don't, maybe someone else on here can find one. The ad had a Bulldog hood ornament superimposed over the Declaration of Independence and the tag line went something like this Yeah it's just a hood ornament like the Declaration of Independence is just a piece of paper! After seeing that I thought to myself well you guys have made it just a hood ornament! They had taken all the history out of the "Bulldog" I'm sure Mr. Masury would not be pleased!

I think a lot of regulars on here know already that the Mack Bulldog was made from a carving. 39 Baby Mack ( unfortunately he doesn't stop by any more) Made a really good post in a thread explaining this. I will post a link to another thread , and in that thread is a link to the original post . Sorry, I hope that isn't confusing , lol The bulldogs used to be different from one side to the other . and Mack mirrors used to match the left and right side of the bulldog . Not sure if this helps anything . But someone may find it interesting . https://www.bigmacktrucks.com/topic/43937-mack-mirrors…something-interesting/?tab=comments#comment-323522

It sure was ready to be changed , lol . Thanks for the update .

North of the border is $ 2.399 / Litre. There is close to 3.8 litres per US gallon . That translates to $ 9.11 gallon ...... and its supposed to go up more here.

Looks amazing . I really like your choice of colours

PAI used to list a stainless one in their catalog , EEM-1916 ......... I doubt its available though

I wonder if this is your trans ? TRD(L) 722

It was probably a good decision. Now you can count the days to your retirement.

I love it !!!

I liked it to Bob , I was on a job and it came in and backed up to the house like it was a dry summer day , lol

I thought I had done it easily ?? But apparently I didn't . Because I just went through to try to delete some photos and the only way I could was to go to my attachments , then to the actual thread , then edit my post by deleting the photo. I would have thought ? there was an easier way. Hopefully Bob can help some more . I did find this cool pic I posted A long time ago , lol . Its actually cool going through old pics 😄

Thanks for the update . Thats a really cool R

LOL, well done.
