There's a long straight hill near me that frequently turns into a sheet of ice during snow storms. Before you go down it you slow down so you can make sure its not blocked off by people getting stuck coming up. One car will get stuck halfway up, the next car that comes up will try to go around them and get stuck at the same point, the next guy coming up will try to go around both of them by using the shoulder, and get stuck at the same spot. Before you know it you've got 5 cars across blocking the whole road. Meanwhile my dodge 2500 cruises right up it at 45mph with the plow off the ground. My single axle Ford L8000 salt truck I have to lock the rear axle and use my momentum to carry me up the hill, but I'm empty and headed to get loaded when I hit that hill, so I have no weight to speak of. One of the perks of the whole "green" movement is they've made cars lighter and lighter. Which makes them worse in the snow.

Yea the one we did the major framework on 2 years ago is the truck that went into the ditch. 😭

Cab is off the cutoff. Hopefully we will get it into the garage on Monday so I can start stripping it down. Might be a bit of a juggle to decide what to put where in the garage. Might make a wooden cradle of sorts on wheels to hold the new cab that my forklift can pick up and move around.

Worst storm I've had to plow so far was 45 hours straight with a half hour nap halfway through. Guy I usually plow for picked up a shopping mall on the edge of Philly with "zero tolerance". It's a constant 24/7 operation, cars and pedestrians all day and restock employees all night.

About half an hour north of Philly. Just some arctic air dropping south for a couple weeks. Jetstream will push it back north sooner or later. I'm running a thread in the "modern trucks" section. Though at 21 years old it's not really a modern trucks.

Supposed to get 3-5 inches on Tuesday, but you know how accurate the weather man is this far out... I'm pushing to get the cutoff's cab off and in the garage before then. We've got 2 weeks of sub 35 degrees coming up, which makes it too cold to pour any concrete. So it'll be a good opportunity to knock out the rest of this cab swap. Our trucks never go out in the snow, but I've plowed snow off and on since I was 18. This year I just have to worry about plowing my own 7 acre property, which is a nice break from years past.

Someone on here said they replaced their engine wiring harness and it made a big difference in engine performance. Said it should be added to the tune up list

Glad you got home safe, we haven't had much of a winter here in southeastern PA in a couple years now. Some cold coming in next week, but no snow worth talking about yet.

Atta boy!

+1 on that radiator shroud looking goofy. That fan is way low and tiny compared to that massive radiator. Also, I'm entirely unfamiliar with B's, are the X braces above the engine normal in B's? They've been cut, which is no big deal to replace.

Mixer is largely fine, a little porta-power work, a little welding, and a couple small covers and the mixer should be (almost) good as new.

I had hoped to avoid Plan B on the cutoff, but seeing as we couldn't get any of the aluminum bulkhead connectors to unplug, I had to cut the big harnesses on either side. About all that remains is the oil gauge pressure line going to the cab from the filter housing and the transmission shifter cable. Should get those done pretty quick tomorrow afternoon after concrete, then hopefully we'll have time to lift the cab off the chassis and get ready to bring it into the garage to strip down, patch a hole in the floor, and a few other things to get it ready to go on the truck.

My '79 endt676 we tried a small filter they make that goes right on the compressor, so it had an intake independent of the engine. Still pumped oil.

"one of three" claims could mean a couple things.... One of three that he has for sale? One of three like that that the original purchaser bought?

Old cab staying warm and dry.

Chassis is sitting in the garage, not sure there's anything left to do today. Need to pull the spare cab off the cutoff, steal whatever we need for the radiator/CAC assembly on this truck, install/gut new cab, swap guts from our cab to the new cab. Hopefully we can work in a coat of paint on the new cab before it goes onto the truck.

Photo dump from today. Only trust a Mack to work on a Mack.

What's the plan for this machine?

That's pretty awesome. Never know what someone will find logging into this site! I hope it runs, it looks clean, no rust in that flyer. I'd love to see that thing working on a job site, but I don't suppose that'd be good for preservation and whatnot. Probably didn't sell more as a Scraper does the work of 2 pieces of equipment, self loads and hauls it off to dump.

Fair question, Joey. To elaborate on noises the air compressor can make: my '79 makes a ticking sound when the air compressor is building air pressure, and stops when the governor cuts off the air compressor. It's subtle, but maybe yours is behaving similarly?

My '79 makes this kind of a pop pop on throttle let off. Let us know what you find on valve lash.

Fortunately I have this gem of a 14,000 original miles ETECH 300 spare for any SNAFU's 🤠

Starter is relatively new, changed it 2 years ago during our frame overhaul. Batteries relatively new, but they did lay on their side for a few hours during the rollover and then sit for 2 months. Truck has a battery kill switch on the battery box, but it is underrated IMO. It gets hot from excessive cranking. Once the truck was running under its own power it was charging at 14.250 volts according to the laptop. Restarted on its own no problems after we let it run for a few minutes. Voltage issue doesn't concern me, but it's helpful for people to know how bad voltage can affect trying to start an electronic truck. The slight miss is going to need to be looked into, while this EUP system is good, there's nothing better than PLN for durability. We have not adjusted the valves, never even had the valve covers off. I keep hearing the term CCRS. What is CCRS, and how's it fit in the ETECH/ASET family?

Considering the same year block can put out 25psi boost on the 283hp version I can't think of anything that'll get hurt at 20psi. That head you had rebuilt would make me nervous, it took a beating. Wouldn't be surprised if a valve seat worked itself loose... The fuel pump is what limits the truck on power. The turbo will only put out enough air to match the fuel pump needs. I think. Basically the fuel exhaust drives turbo, so when you run out of fuel potential you run out of turbo potential.

Truck has about 430k miles and over 27,000 hours. No idea if the engines ever been rebuilt, so maybe injectors are squirting a little funny. Would be curious to look into injector spray pattern testing tools, no idea if there's anything affordable for occasional use.
