Rmodelwrench Posted November 22, 2018 Share Posted November 22, 2018 Hey I just picked up my first mack I’ve always liked the look of an R model. My intentions are to convert this rig into my next service truck it is a R688ST 9 speed Eaton 300 hp E6 4valve with jake brake 420k miles single frame 2 Quote Link to comment Share on other sites More sharing options...
1965 Posted November 22, 2018 Share Posted November 22, 2018 Very nice; but I thought 688 was a 350hp Quote Link to comment Share on other sites More sharing options...
Rmodelwrench Posted November 22, 2018 Author Share Posted November 22, 2018 I’m not sure I was told 300 anyway I could verify? Quote Link to comment Share on other sites More sharing options...
41chevy Posted November 22, 2018 Share Posted November 22, 2018 Seen them with both OEM. Look at the spec tag on the engine. Your 688 could have a 350h.p. or a 300 h.p. in it.

gxbxc Posted November 22, 2018 Share Posted November 22, 2018 I wonder what it was used for that short bed makes it look like it was once a tractor ,but it sure looks nice and clean inside , wish you all the best. I used to drive a 688 long wheel base with a tag axle and a crane on it ,used to pull pup about ever other day,truck road like a caddy. never spilled my coffee even when I left it on the deck .

mackey58 Posted November 22, 2018 Share Posted November 22, 2018 That's gonna make one hell of a service truck hope to see pics with a service bed fully loaded with a crane that would make a nice Christmas present lol Quote Link to comment Share on other sites More sharing options...
Rmodelwrench Posted November 22, 2018 Author Share Posted November 22, 2018 Thanks guys I looked at the tag E6-300 the p/o said it was a tractor he put the flat bed on it then ended up with a early 90s Rmodel with only 70k miles so this one had to go i will definitely keep you guys informed on the build and will have plenty of questions myself. Now that I got the rig I want it’s finding a clean used bed and crane I think my best option is going to be buying a complete service truck.
