That is a good looking truck though....
-
We deleted the one on our '79 endt676 because the fitting on the intake manifold broke. Barely makes any smoke, but this truck has always spooled up fast and ran like a beast.
-
I've never seen a Mack that makes 38 psi boost. My older endt676's peak at about 27, and my e7-350 is the same.

Sometimes filters clog slowly... And they do just that. Slowly over time they "trim" your governed speed lower and lower as the filter acts as a restriction point. If you haven't changed them recently then it's definitely worth doing before you go jumping on a $3,000 pump rebuild.

Well we don't know what your symptoms are so..... More info please

88 Superliner cab interchangeable
JoeH replied to Whishy's topic in Exterior, Cab, Accessories and Detailing
My 1988 had Ridgid mount cab but front pivot. My 79 has the same, Ridgid mount cab plus firewall to radiator supports. '79 has pivot front mounts. -
Finally got it out of the garage for a little test drive.

Repost this picture anywhere you think is useful. Lift axle chart for lbs to the ground depending on air bag psi for a Link Mfg 20k lift axle.

In PA if you're registered for 73,280 they don't care what your wheelbase is. This truck will be 73280 on a 195" wheelbase, intrastate only.
-
This brand (CemenTech) is in Iowa, and the bulk of their sales must be in parts of the country where you have a mile to make your turn because they need 168" back of cab to center of tandem. In the suburbs of Philly that's borderline impossible to get into people's driveways, let alone into their back yards! Hence the MR setup for this mixer.
-
It's going to be a volumetric mixer, not a barrel. Mixer holds sand/stone/cement/water/admixtures in different compartments then siphons them off as needed to make concrete. It all drops onto that auger on the back where it's mixed into concrete. Perks are maximum working time (concrete isn't mixing in transit) and (if your driver knows what he's doing) control over every aspect of your concrete. Slump, sand/stone ratios (sometimes we show up and the customer needs us to cut back on the stone and bump the sand up to do an overlay on existing concrete). We got our first one of these trucks in 1967.
-
Whats wrong with glass and a dump truck? We're a small concrete delivery company, so this truck will be operated in a 15 mile radius. Tons of residential deliveries, backing into driveways, around houses, etc. The maneuverability is going to be insane on this truck. Short footprint has me a little worried about stability on a full load, but we'll just have to watch what we're doing a little more closely.
-
Sidenote, don't crank an engine for longer than 10 seconds. You'll overheat the starter and burn it out. If it cranks but won't start and has a Check Engine Light on there's no sense in killing the batteries and starter. You're on the right path trying to get this code sorted out.
-
Clogged fuel filter symptoms are exactly that. Your truck acts like the governor is kicking in at a lower RPM than you remember.
-
Change your fuel filters. Primary and secondary.
-
Few more odds and ends, including painting the cab then this truck will be driving to Iowa! Hope the top speed isn't 50 mph, we've never had this thing on the road, lol!
-
That frame doesn't look very happy. Do you plan on straightening it?
-
Engine picture is a 1981 ENDT676, quietly waiting for the next time our 1979 needs another engine component. So far it's donated it's camshaft and a lifter tappet and the air to air intake housing. And some valve lash adjusters. Dealer wanted $80 each and only had 3, couldn't get more.
-
Matt's Heavy Duty Mobile Diagnostics in Sellersville, PA came out this afternoon. Tech (Cole) did a good job sifting through. Scanner immediately showed no power to the EECU. He managed to find the EECU power relay in the dash with no fuse/relay diagram, and found spread connectors for the related fuse. Truck is up and running! I think all we have left is to mount and plumb up air tanks and move the battery box as it interferes with the mixer peripherals.
-
Could be your pump/pressure relief is failing. We have an old mack truck here with no power steering. You can't turn the wheel for shit unless you're moving. If you hit a bump it rips the wheel out of your hands.
-
Yea, he's probably tight up on money. Sounds like piston rings or worn valves. If you give him 5k down and he uses it to "fix" the truck and you decide you don't want it: good luck getting your 5k back.
-
I have 2001 in my head as the ideal year for a Mack motor. Rebuilt engine in the last three years? If the frame is clean I'd take it if the wiring harnesses look clean. 2001 is the first year they moved the engine computer to the left side, away from heat and possible pinch against frame rail. Emissions BS with the ASET engines started sneaking into the trucks in 2003 and was in all 2004 trucks.

I'd talk to someone in your state about axle weight configurations. In PA we get away with 73,280 on steer, lift, and tandem. Other states require 4 or 5 rear axles to hit that much weight. Don't know what Arkansas allows. Pull up and ask a state trooper next time you see one! As far as being caught overweight on one axle, DOT enforcement has portable scales they'll use to weigh each wheel. If you're moving dirt on site you don't have to worry about "legal" weights, Mack rates their 44k rears for more if kept below a certain speed. If you're going down the road it's another story.
-
Lift axle bolted on. Have the trans power sorted out, but now we have a blink code 6-4, cranks but won't start. Mobile diagnostic guy comes out on Wednesday to try and figure it out. Yea, we're planning on driving this sucker out to Iowa (from Philadelphia area) by the end of this month... Call us crazy. I'm not looking forward to a probable breakdown on the 20 hour drive...

1980 Steel Nose Headlight Options!
JoeH replied to Wirlybird's topic in Antique and Classic Mack Trucks General Discussion
If I had a 1908 I don't think I'd be driving at night, I'd be too afraid of hitting a deer!
