Lmackattack Posted March 1, 2011 Share Posted March 1, 2011 I have a friend asking me about some of the Mack RS/RL 700L with the Detroit V12.He pointed out a few things that I have never noticed. First was the side filler panels behind the air cleaners the other was the lack of the cowl vent. Anyone have pics of these thigns up close? hood open to see how they got them in. He is a model builder and is looking for some specific details to reproduce.

Rob Posted March 1, 2011 Share Posted March 1, 2011 I have a friend asking me about some of the Mack RS/RL 700L with the Detroit V12.He pointed out a few things that I have never noticed. First was the side filler panels behind the air cleaners the other was the lack of the cowl vent. Anyone have pics of these thigns up close? hood open to see how they got them in. He is a model builder and is looking for some specific details to reproduce.Most likely the filler panels are modified from normal to use the dual "Farr" air cleaners. Those things really free flow air but do not silence at all. A Detroit with them is quite loud during operation. I surmise the cowl vent was eliminated to allow clearance for the rear blower on the engine as they sit quite high in the valley. This coupled with the air intake adapter to feed both blowers I'd think the vent would be in the way.I've never seen a 12V-71 powered R model before so these are just s.w.a.g.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

The hood on the tractor looks a little longer, an where the vent goes, it almost looks like they narrowed that area for the hood maybe?? also the extensions on the sides under the air cleaner?? now i just got to figure how to get it to Jersey!!!

Lmackattack Posted March 1, 2011 Author Share Posted March 1, 2011 that 72 looks like a newer cab and wondering if it was also a v12 truck at one time as it has cowl extensions also. From what I recall the v8s fit under the RS700 hoods just fine.

LOL!........MarkTo my ratio and proportion eye I'd say the hood is the standard length for an R700. This is judging by the wheel opening radius and placement, the length of the hood extension from the back of the fender rearward, and the length of the flat portion of the hood panel itself. I don't see any difference in any of these measurements from mine. This is of course, just a guess.A Detroit "V" series engine in a straight frame rail truck would be a tight fit. I'm certain it could be done but with the splayed frame of an eastern R model, the engine could sit lower in the frame and probably not have some of the clearance issues of the straight rail truck such as an RS, or RL700 series. This is why I'm going with the R795 for my project.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

bullhusk Posted March 1, 2011 Share Posted March 1, 2011 OK guys, The truck does not run the motor is not siezed but needs work. Not crazy about the rear susp.(Pag&Page) but i have a nice air/ride out of one of my wrecked Pete's that might look good under there? Now the other truck? the one with the E9 V8 that was #2 of the three with the Alm. frame but he put the 440V8 into it!! crazy right!! Both those trucks were used in the logging ind, up there in WA. so says the owner but we'll see? I'm just a little worried about the frame?? But i spoke to the owner tonight, an was told again the only thing wrong was the motor needed work but I just might take a ride out when they load it up or maybe even take a ride out with one of my guys an pick it up (I don't have a drop deck but they do rent them by me)it's just with the price of fuel right now the hauler might be cheaper?
