cf685f Posted April 18, 2016 Share Posted April 18, 2016 I'm looking for a tach drive cable for a 1988 R688st with a 350 4v. Raleigh, NC. Let me know if you have one for sale.

Vladislav Posted April 18, 2016 Share Posted April 18, 2016 Recently I saw some on ebay. Just put something like "Mack cable" in the search field. But usually you have to figure out wich one would work for you. Knowing the original number is an advantage.

85snowdog Posted April 18, 2016 Share Posted April 18, 2016 I just got one for my R688st part # 54MT313BP94 . I believe ? but not sure, the last numbers of the part # is the length of the cable. Cables range from 80 to 218 inches , I think ? You can get them from Mack . I don't really have a user friendly Mack dealer, so mine came from PAI , it was only around 25 bucks .

cf685f Posted April 25, 2016 Author Share Posted April 25, 2016 Next crazy question, my cable has been removed. Where does it connect to on the E6 350? I get that on order this week.

cf685f Posted April 27, 2016 Author Share Posted April 27, 2016 Thanks, just got that number to PAI. Its good so the cable is on the way. $25 bucks to the counter. Thanks for the location picture. I guess I have to clean the crud off to see the connection point. All in all I should be back in business. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/44875-1988-r688st-tach-cable/#findComment-331730 Share on other sites More sharing options...
