storkmack Posted April 29, 2012 Share Posted April 29, 2012 I looked at a R770 after church this morning. I know that it has been updated as far as motor and rears/susp. What I am wondering is, what did it leave that factory with as far as a motor. The VIN is R770ST1128.

umodelnut Posted April 29, 2012 Share Posted April 29, 2012 All I can help you with is that R means R model, 770 prolly means V8 or long nose R model (R700), ST means tandem tractor, and 1128 means it was the 128th R770ST made.

storkmack Posted April 29, 2012 Author Share Posted April 29, 2012 Thanks, Vinny. I had a handle on all of that. Just wondering what it had for a power plant when new. -Brad Quote Link to comment https://www.bigmacktrucks.com/topic/24816-vin-decoded-please/#findComment-116798 Share on other sites More sharing options...

Green Dash Posted April 30, 2012 Share Posted April 30, 2012 I found one source that shows an 8V92 as the original engine. What year is it? I think the 92's came out in '75 or '76. 1 Quote Jim Link to comment https://www.bigmacktrucks.com/topic/24816-vin-decoded-please/#findComment-116867 Share on other sites More sharing options...

It's an Austrailian forum so no U models, they like their Macks fair and balanced. The info appears to be accurate, I'd go with it.http://www.hcvc.com.au/forum/YaBB.pl?num=1286326467 Quote Jim Link to comment https://www.bigmacktrucks.com/topic/24816-vin-decoded-please/#findComment-116904 Share on other sites More sharing options...
Superdog Posted April 30, 2012 Share Posted April 30, 2012 8V92 Detroit would be correct for the R770,a 8v71 would be a R773,a 12V71 would be a R771. Quote Link to comment https://www.bigmacktrucks.com/topic/24816-vin-decoded-please/#findComment-116917 Share on other sites More sharing options...

57 bcr Posted May 6, 2012 Share Posted May 6, 2012 Jim has had that truck on the road for many years,as you know.When I started in '86 it still had the Detriot in it.He since put a 350 Mack in it,went from camelback to taper leaf to air ride.I would not be afraid of that truck at all.It was always kind of different with the Detriot and that Roadway-style under the hood air cleaner.

Rob Posted May 6, 2012 Share Posted May 6, 2012 And if you don't wind up with it Brad, I might be able to make so room down here for it. By the way, is the loft still open in the barn? If I buy another truck, I'll need it.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

If I buy another truck, I'll need it.RobI have come to the conclusion that I can not drive every sweet ass R-model I come across. I would like to try too. This truck has an EM-7 300hp, Fuller 13 speed, on Mack rears with the older hendrickson style air ride. It also has air ride cab. The real cool thing is that it is set up with an air start. Very un molested truck. I also like the fact that it is an 81' year model, because I am also an 81' year model. I did noy talk to the gentleman that owns it, and he does not have his number on the for sale sign in the window. I do know that the truck was still on the road in March, because he was runnning the same route as we were at that time. -Brad Quote Link to comment https://www.bigmacktrucks.com/topic/24816-vin-decoded-please/#findComment-117991 Share on other sites More sharing options...

They really don't even need to run, (they do) it's just something to talk about with the visitors which continue to be many. I'll be up in Elgin for more training in the next couple of weeks and will stop by.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Nice looking truck. Seen another over to the side which looked nice also. Didn't want to get out till I'd met up with you as didn't know if Jerred was there or not.
