2019 mack triaxle dump rattle since new
JoeH replied to vinny933's topic in Driveline and Suspension
They're not hard to replace, but they take big guns and floor jacks, and a BA torque wrench. Because it's got a warranty from manufacturer defects I'd make them do it. -

Didn't know there were 46k camels. 38, 44, 55, 68, 80, is what I thought there were -
Change it, run it for 15 seconds, and shut it off. See who the belt is slipping off of or rubbing against. I'll bet you'll find someone not aligned properly.
-
Seems the wheels get left behind when you pick em up. Good opportunity to get em spinning.
-
They make equipment that can pick it up to work on, I'm sure there's a way to lift it onto the tracks. Just gotta get it to the tracks.

Understood. That's a weird serpentine setup, I would have expected crank, water pump, alternator and tensioner to be together and the AC to be on it's own, driven by the fan/water pump. Are you buying belts from the dealer or cheap Napa belts? Napa is fine for cars etc but they're sh*t for trucks IMHO.

They probably installed wrong size ones, from a lighter Camelback. I'd bitch because it's a new truck. Older versions of Camelback don't use them. Our 79 R model doesn't use those #7 or the sideways torque arm to the frame. Has rubber trunion bushings and the axles walk as much as 8 inchs out of alignment from each other. -
To clarify, as I'm not real familiar with CV's, the thin belt is to the air conditioner from the fan? Separate from the serpentine belt? Take the belt off the AC for a day (driver will hate me) and see if the serpentine belt holds up. AC is a creature comforts, not mandatory. Engine water pump and fan spinning are mandatory.
-
No it should be able to run anywhere. Something isn't right on it. Check engine damper wheel run-out. Maybe the crankshaft is bent.
-
Don't need to truck it far, just make sure the axles spin free and put it on a freight line to where ever. We donated a couple rail cars a few years back to the New Hope Ivyland Railroad. We still had a rail siding attached to SEPTA's R5 route, so they were able tow them out with a freight train in between the Commuter train schedule.

Post pictures of tensioner etc. My 12v Cummins dodge belt likes to rub on the arm of the tensioner because the AC compressor pulley is some cheap China knock off. Jumps one rib on the AC pulley then it's happy, after it eats one rib off the belt though...
-
That trucks not getting anywhere under it own power without some dead weight in the back. That front axle is buried deep. A gentle tug from a 4x4 pickup may help...
-
Can you delete the worn lift pump and install an electric lift pump? Make a cover plate for the old lift pump location?

RAT ROD FIRST SHOW-66dc75
JoeH replied to Red Horse's topic in Antique and Classic Mack Trucks General Discussion
I have two old 237 horses, used as yard trucks once in a blue moon. They both smoke. Never get worked hard. Injectors good be lazy and worn out, sleeves could be worn out or need to be re-honed, valve stem seals could be dry rotted and leaking oil... (I forget if these engines even use valve stem seals) If I re-honed them I'd have to do the brake in procedure which isn't possible on these. -
Wikipedia has the story. Basically the company has been around since 1908? Used to make auto cabs for a lot of companies until GM bought em out. Tags were just their way of putting their name on their product.
-
That's what I would assume, this ones in backwards I suppose...
-
+1 to 80k. We just bought a triaxle that's rated at 80k with no hitch.
-
Cab has a Scott Contractors logo faded on the door. We've owned it a long time, we wouldn't have put it in. Which way were the tags typically oriented? This one is upside down when standing outside the truck. Probably not the factory orientation.
-
Anyone else ever see one of these stamps in their R model door sill, driver side? A quick Google search shows Fisher to have been a cab manufacturer of automobiles, but Wikipedia gave no hint towards a relationship with Mack.
-
Anyone else stop scrolling and just stare when they saw the lug nuts? Or just me? Looks like hydraulic rear brakes. Does not look like a triple frame.

Assembling a Volumetric Concrete Mixer, and thought I'd share a welding trick I learned about and am trying to keep large pieces of sheet metal from warping! Use drywall compound as a heat sink to keep heat from extending out into the sheet. Share your welding tips and tricks below.
-
What do you mean by higher?
-
Wow. I'd be worried about stopping power! Roads must be pretty flat out your way. Here in Pennsylvania we have up hills, down hills, sideways hills... What axle ratings do triaxle have that they can hit 120k? Even with a 58k Camelback you'd have to have a 32k lift (pusher) and a 30k steer...
-
Seems a bit light for 10 yds, out my way you have to be a triaxle for 73280.
-
I would have dragged him along after he set it to 0 mode on the econdyne. Why would he monitor it, change it, and not monitor the change? Give you raw data to see what changed and what didn't? Only thing I could think of for cost variable is the engineer time to design the fuel map. But you already paid for a 505 with a fuel map, it seems stupid to me for them to charge you 3k because you picked a fuel map that you don't like. I wonder if you could pick up a used maxidyne ECU for cheap. Wonder if it'd conflict with everything else, truck miles, vin, etc.
