Popular Post Superdog Posted April 21, 2013 Popular Post Share Posted April 21, 2013 Mikey & I just got home with this one,1986 R686ST,local contractor had it for a lowboy tractor,but parked it 5 years ago with transmission problems.It was just up the road about 5 miles so we decided if it would run,we'd try driving it home,figured it's a Mack,it will make it one way or another.Put in some fresh batteries and a little shot of ether and she fired right up.Took a little rocking to get it out of the spot it had settled down into but she evidently wanted to come home with us and finally worked up out of the ruts.Old girl runs good,but has issues in the hi side of the transmission,syncro's I'm guessing,it's a T2090,has a E6-300,4:42's on Camelback,budd wheels,body is pretty good,interior is a little rough.Damn near brand new Holland 5th wheel,air ride cab,decent tires,but they are lo pro.22.5's,so she ain't too speedy. 6 Quote Link to comment Share on other sites More sharing options...
storkmack Posted April 21, 2013 Share Posted April 21, 2013 Nice solid R-model there. Bought a 90' RD688 this week with the same transmission issue as yours. The one we picked up is an E-6 350, mack 9 sp, 5.02 rears on camelback. It will be a spare truck for us. -Brad Quote Link to comment Share on other sites More sharing options...
umodelnut Posted April 21, 2013 Share Posted April 21, 2013 Sweet!!! Whats your plans for it Mike? Quote Link to comment Share on other sites More sharing options...
Superdog Posted April 21, 2013 Author Share Posted April 21, 2013 My first thoughts were to pull the engine for my white '88 Superliner,and use the rears for my '74 RS795,then sell the rest as a glider,but when we got it home and I scraped the dirt off and found out it had 4:42's,that kinda blew that idea,at least for the rear ends.Maybe somebody will come along that wants it real bad.

Nice save though. I do like the padded door panels. Quote Link to comment Share on other sites More sharing options...

Superdog Posted April 21, 2013 Author Share Posted April 21, 2013 one thing about this R model has me puzzled,there is absolutely no room for a grill of any kind,the ATTAC is tight against the hood opening.Must either has wrong hood or wrong ATTAC.

Vladislav Posted April 21, 2013 Share Posted April 21, 2013 one thing about this R model has me puzzled,there is absolutely no room for a grill of any kind,the ATTAC is tight against the hood opening.Must either has wrong hood or wrong ATTAC.Grill opening into relation to air to air looks quit the same as on my R688. There are bolt holes in the upper and lower cross flange to attach grill.I can't be an expert until I recieve my grill. But some bodies on here helped me researching that.

Mike Posted April 21, 2013 Share Posted April 21, 2013 Nice lookin R and looks like it stayed all Mack, by the looks of the mudflaps.mike Quote Link to comment Share on other sites More sharing options...
fullfuel01 Posted April 22, 2013 Share Posted April 22, 2013 Older hood style is 2'' shorter then new hood style. Not talking about the new rd with square headlight. This change was made in 84-85 when they added the air to air. Might be the reason Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted April 22, 2013 Share Posted April 22, 2013 82 had air to air to. least ours does at work unless its not really an 82, but it had the tan interior and the tin grille just bolted to the air to air Quote Link to comment Share on other sites More sharing options...
Superdog Posted April 23, 2013 Author Share Posted April 23, 2013 I got to looking at it closer,musta had one of those that was mounted to the air to air.Once the cab aired up,there was more room there than I thought.I'm just to used to the older R's that either had shutters or the fake shutters.
