I haven’t even had a load on it yet. But how do we get it to 1 gear to pull out of a tuff stop? Can’t with this shift pad??? It was originally part of the cvs fleet so it probably never seen anything it asphalt. What’s the astric do nothing?

Bought a 2015 with a m drive for fall help. Has 360k miles Hopefully will last a while. Question is it has the fleet shift pad. Has the m but no + or - key. What would it take to switch to the one with performance mode? Is it plug and play or need software update. if you push m should it just go to 1 to start out of a tuff spot with the key pad I have?

Been discussed before I'm sure but is there any way a 1981 r686 came with the dark grey interior? Truck has what he claims is a 300 but isn't tip turbine says econodyne on the hood. I guess I thought in 81 it would be tip turbine an tan interior originally had a 5 speed been switched to eaton 13 which I would think would work kind of odd with that engine. he claims other then the 13 its all original

Did the ac systems ever work right on these trucks. This one when charged will work som what until you shut down to go into town then that’s it won’t work again. New clutch on the fan the radiators are clean. It has that diagnostic box on the side of it.

http://Agdieselsolutions.com anyone ever put one of these boxes from ag diesel solutions on a e7? Would be nice to bump the horsepower a little. I guess I don’t know how to post a link

I will Have it in my hand Monday afternoon. Thank you for the help. I’ll keep you posted.

I will. We’ve had a Mack some where in the family since the b- models which were way before my time. When I was little you could go to Rochester and see close to 100 r models sitting in two yard. WAs definitely different times.

Rochester indiana.

Yes I see it 45 with return line going in the back side of it. Thanks for the help. Kinda of in a bad spot closest Mack dealer 60mile in a direction we don’t get very often. Not to mention they don’t want to screw with these old trucks

This isn’t going to fix my problem though is it? Just something else we found along the way.

Ok I put another guage that just goes to 60 and it spun it again the zero stop and bent the needle so I’d say it’s right. I’ll call Mack in the morning and get a regulator.

Engine oil is right on the full mark

Unless the gauge is no good but it’s a good oil filled guage

I had it running twice it’s hard to hold the hose clamps on what I had available so I’d guess that’s right. What regulator we talked about??

Fuel pressure at idle is 115ish
