cf685f Posted March 2, 2016 Share Posted March 2, 2016 Well I did it again, I looked at a truck, test drove it and brought it home! I have a CF, but I have really been wanting a Supliner or an R. I have been looking for years on Craiglist locally and last weekend a two owner R popped up. Its a 1988 Mack R 688st. It originally was a fuel tanker for McKenan Transport out of Apex, NC. They sold it to a local contractor who had been eyeing it up since new. He jumped at the chance to buy it and he pulled a dump trailer and lowboy. Unfortunately, he passed and his family no longer had use for it. They keep it a couple of years moving it around the yard and last week decided to let it go. Its was priced right and being a southern truck it had no rust holes. Dents and dings through out but it has never been refirb'd in any way. AC was the only thing that I could see on a quick look that was not working. Two scrappers and one exporter in line behind me, so I had to purchase it on the spot. I don't like to be in those situations, but I pulled the trigger. Im a firetruck guys, so I bought on a feeling that it was worth the risk of the unknown. I don't have a vin decoder so I thought the experts here could fill me in on what exactly I bought. I drove it home 100 miles and it ran flawlessly, so Im hoping that a good sign. I hope!

j hancock Posted March 2, 2016 Share Posted March 2, 2016 Congrats on the new truck! Sort of like trying to have just one potato chip. We need pics and info.

cf685f Posted March 2, 2016 Author Share Posted March 2, 2016 Pictures, sorry I was trying to figure out how to reduce them in size. http://s266.photobucket.com/user/firetoolman/library/1988 Mack R R688st 1 Quote Link to comment https://www.bigmacktrucks.com/topic/44211-new-truck/#findComment-326304 Share on other sites More sharing options...
cf685f Posted March 2, 2016 Author Share Posted March 2, 2016 Ok, hopefully you guys can see these photos. Thanks J. I'm really excited about it. Once you guys weigh in Ill know for sure but Im thinking its a 350 with a 9 speed. Starts right up and runs out very nicely. I have an old 237, so the extra HP really helps this one move out. Since it was an over the road tractor it really moves out good. I think it will run 80mph, no probably with those freeway gears. Feels like a race car compared to my 237 with 5 speed that maxes out at 55.

thomastractorsvc Posted March 2, 2016 Share Posted March 2, 2016 Congratulations. Looks like a pretty decent save and appears from the pictures to be in good shape.

j hancock Posted March 2, 2016 Share Posted March 2, 2016 688 would have been built with a 350. Looks Good! Quote JimIt doesn't cost anything to pay attention. Link to comment https://www.bigmacktrucks.com/topic/44211-new-truck/#findComment-326316 Share on other sites More sharing options...
85snowdog Posted March 2, 2016 Share Posted March 2, 2016 Very Nice !! Like Jim said, its an E6 350 4 valve. I have the same thing a 1988 R688ST . Don't knock your 237 though. Its not fast, but it will get you home every time. lol 2 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/44211-new-truck/#findComment-326319 Share on other sites More sharing options...
cf685f Posted March 2, 2016 Author Share Posted March 2, 2016 Cool I was thinking it was a 350. I have alot of cleaning to do, but I think most of it will buff out with some sweat. I need some matching aluminium rims for the front. The hoods a little rough in some places, but it appears that hoods pop up in the classifieds from time to time. Hopefully I can find some used matching rims for the front and I have aluminium the hole way around. I think a good interior completed steam clean, a cab cleaning and a new rubber floor map will make a world of difference. Question, the tachograph is not working and is a little hard to read when driving. Could I change that out for another dash with just a regular speedometer and tach? Thanks for the kind reply's and I look towards my first ATHS show this summer with something other than my firetrucks.

My B42 Tops out at about 43 on a flat, and I'm told my ALF 700, were it actually running, would only do about the same..... I'm OK with 43mph, but it sure makes the lines of cars behind me very unhappy! And it's even worse if I hit a hill, and it slows down to about 35.....
