Nothing is ever easy it seems.
JoeH replied to Licensed to kill's topic in Antique and Classic Mack Trucks General Discussion
I'll put my lists/reminders so they're sticking out of my wallet so I can't miss them in the AM when I'm getting ready to get out the door. My dad is 70, and he's a list guy, always has been. The amount he gets done every day is impressive. -

A piece of paper with a list of small achievable tasks does a lot to get you out the door and moving. Evening before, write down a few doable tasks, cross out as you go. Next evening add a few more to the list for the next day. What ever you don't get done is carried over to the next day. -
Just be glad you aren't doing this on a DM cab, the rear head is halfway under the firewall, and the firewall comes right up passed the back of the tires. Very cramped!
-
Its a good thing this is such a durable engine, I've done this process numerous times. Its not fun. I've never seen a closed end cross foot, all the ones we have are open end and the square port is right by the open end, no handle length.
-
You're also dealing with a manual trans you said, so you have different sensor inputs and outputs. And you have a GU813 which is probably an mp series engine whereas I have a vmac III etech engine.

We scraped the sand out often one bin at the scene, but it still has a fair bit of stone in the one side. And the cement bin on the back is mostly full. Drivers job tomorrow is shovelling the materials off the truck before it goes to a collision center for evaluation. If the mixer body has to come off then it needs to be empty.
-
Hoping it gets new wiring harnesses, wires weren't in great shape before this fiasco.
-
Shockingly almost nothing wrong with the mixer. Passenger cab corner took a heck of a beating. Its such a beefy frame I'm hoping the bones are all ok and it just needs a cab and miscellaneous small stuff. No spilled liquids, though it did tear a fuel line somewhere next to the engine, probably from the cab ripping 8 inches back and tearing loose from the passenger side hinge. No injuries, just a bruised ego on the driver. Just got sucked into a 4 ft ditch and fell over. And you can see the remains of that tree, which I'm sure put some hurting on that cab.
-
Annoying on a truck that runs a manufacturing process that requires multiple different materials to be set at specific flow rates in order to make a good product. It throws the flow rate ratios off, and we either have to adjust them or drive the truck far enough (50 yards?) And fast enough (5-10 mph) to satisfy the computer.
-
All I can think is the truck senses a component in the trans spinning from the inertia of the engine revved up and it triggers a code because in neutral/parked the trans sensors shouldn't sense any movement.
-
I have a 2003 MR688S that does the same thing, but it's accompanied by a trans code (Allison automatic) the code stays active and won't let the cruise throttle control "ramp up" for the PTO work until you put the truck in drive and go fast enough for the torque converter clutch to lock up. (5-10mph) restarting truck doesn't work. Gotta lock up the TCC.
-
So I bought these lev o gages and put them on a couple of my trucks last week so my driver went and did this.... I wasn't expecting the lev o gage to get maxed out so soon!

Crows foot won't do 12 point bolt heads.

In pa, bridge law applied unless you register for 73,280. I had a tractor with a short trailer, by bridge law I figured I was legal for about 63k despite axle ratings good for 80k. With 5 axles, steer, drive tandem, trailer tandem, I was not allowed to carry as much weight as a triaxle is allowed with only 4 axles and a shorter wheelbase? Really? Loaded I was 75k, all the tanker trailer could hold. If I had ever gotten pulled over and called out on it (I was pa only on that rig) I would have taken it to court and asked the judge to get an engineer to explain to me my above math.

1, stamped not cast; I couldn't say, my 79 has had thr sane pan forever. I have had a smaller pan crack pretty bad in a couple corners. 2; my 79 ESI+ has 3 filters, no spinner. My late 70's early 80's ESI engines have 2 filters. My 1995 and 2003 ESI engines have the spinners
-
I think you're right Paul. The American tip turbine engine is a headache to tear down, tight clearances under the radiator support arms that go to the firewall. There is a lot going on with those manifolds.
-
If it looked like a bathtub it must have been the + with 3 oil filters
-
ESI or ESI+?
-
27 in the pan, 4 qts between the 2 filters.
-
3 oil filters is the ESI+ (extended service interval plus) and had a 56 quart capacity, with a 25,000 mile oil change interval. ESI was 27 qt pan with 2 oil filters.

Rear diff housing round tube, not square
JoeH replied to SpreadingLime's topic in Driveline and Suspension
The heavier 55k rears are cast iron square; lighter ones were stamped I believe. Post pictures! -
Google says a cat 309 weighs 21,000 lbs, a 427 should pull that just fine. These etech motors are only 12 liters, so they won't pull like a 14-15 liter Cummins or cat.
-
AI-300 or AMI-300?
-
If it's like the endt676 engines, then how many oil filters you have tells what size oil pan you should have. My one truck holds 14 gallons, but that one has the biggest oil pan/filter arrangement Mack made.one of my others is around 9 gallons I believe.
-
This motor does not use hydraulic lifters, that's probably the difference in procedure between this and what you're used to. You have to have the cylinder at TDC so there's no force applied from the cam lobes to the rocker assembly. Each cylinder's valves are only in this resting position at TDC on the combustion stroke.
