martinf Posted June 4, 2008 Share Posted June 4, 2008 So,I've now got my first Mack truck, and must admit Idon't know the first thing about them. This one is a 1971 set up as a logging truck with a Prentice self-loader. For starters, I'd like some help identifying the model, etc. On the door frame was R763S and a serial number of 1574. Is that enough for soemone out there to tell me a bit about my truck...what model etc? And if you could steer my in the right direction as to where I might get some manuals for this truck, I'd be obliged.thanks,~martin Quote 1965 Mack B-74, dump1974 Mack R, logging w/Prentice self-loaderwww.somewhereonthemountain.blogspot.com Link to comment https://www.bigmacktrucks.com/topic/3830-im-needing-lots-of-help/ Share on other sites More sharing options...
Doug Maney Posted June 4, 2008 Share Posted June 4, 2008 What you have is an R-700 model, the 63 designates the driveline. The following numbers are the sequential serial number. I suggest you contact the Mack Museum with this info and request the build information for your truck. It may tiake a little time but what you receive will certainly be beneficial. I suggest you forward a donation to the museum.Doug Quote Interested in Old Trucks?

They will most likely send you a build or line sheet if you ask them Good Luck. An R-700 was one of the largest R-models built Quote Link to comment https://www.bigmacktrucks.com/topic/3830-im-needing-lots-of-help/#findComment-21933 Share on other sites More sharing options...

Superdog Posted September 12, 2008 Share Posted September 12, 2008 A R763S would have a 335 Cummins and left the factory as a six wheel (tandem) straight truck chassis.
