Hey everyone, After years of working on Mack trucks I can tell you that the drivers who keep their rigs running the longest are not the ones with the newest equipment. They are the ones who stay disciplined about maintenance between major service intervals. Here is what most Mack owners skip that they absolutely should not. First, check your air filter more frequently than the manual suggests, especially if you are running dusty routes or construction zones. A clogged air filter on a Mack MP8 engine kills fuel efficiency faster than almost anything else. Second, inspect your exhaust after treatment system regularly. The DEF system on modern Macks is sensitive and an early warning sign ignored can turn into a very expensive repair down the line. Third and most importantly, do not wait for your brakes to tell you they need attention. Mack trucks carry serious weight and the braking system works harder than most drivers appreciate. Regular brake inspections between scheduled services have saved countless operators from roadside emergencies that could have been avoided entirely. What maintenance habits have kept your Mack running strong? Drop your tips below and let us build a resource for the whole community.

The mats was awesome in Louisville but I have to say out of all those trucks I did not see one b-model mack!

Well i figured out how to post my F#$k up

You should see the fence... the picture wont post.......

I screwed up today... I was pulling over on the job site to be out of the way of a big truck. My mirror clipped the fence, I was startled and hit the gas instead of the brake.. I drove My F-350 right into the fence and the long lug nuts on the right front pulled the truck into the fenc and the steering wheel spun in my hands. I was doing a whopping few miles per hour.

You can't register an out of state non-compliant diesel truck in California. Honestly with all the emission controls on these new diesels they are not that much more efficient than gasoline engines anymore.

I just paid $4.89 for premium ethanol free today for the Caddy. The price of diesel at my regular convivence store jumped to $5.49 today!!!

Well regular gas was $3.67 this morning, then at 2pm i drove by and it is $3.99/gallon.. I still dont understand it. Diesel is $5.39/gallon. Why??? I am leaning towards oil exec greed.. Im not smart enough to understand this....

Found a slightly better pic.

Some good ones and according to what I’m seeing,,,, with more demonstrations going on including here,,, people do think he’s king .. wow

Saw this beauty for sale in the UK.Seems to have done a lot of work to it.Look up the web page theres loads of pictures of it.... Paul

Ok guys, while volunteering at the Mack Truck Historical Museum, I had chance to work on a steering column mounted Signal Stat turn signal module with the rare 11 wires. Since the internet doesn't show the wiring for them and the unit is obsolete, here is the wiring explained. Signal Stat (Sigflare) 900, 11 wire Standard wires (also on the on 6 & 7 wire units): Blue (if present) - Input for internal indicator light (from 3 prong style flasher module, "I" pin) Yellow - Input from flasher module (blinking on-off) Gray w/Black trace - Input from Brake switch Green - to Left front turn signal light Red - To Right front turn signal light Gray - to Left rear Turn/Brake light Black - To Right rear turn/brake light The 4 wires extra wires Red w/Black trace - feeds power to front turn lights filaments when turn lever/4-Way is not active (NC). Opens appropriate contact when lever actuated and connects it to flasher, and the other light stay as marker/parking light. (use ballast resistor to dim filaments for running/parking lights) White - Auxiliary Common (NC) White w/red trace - Auxiliary Right White w/green trace - Auxiliary Left Notes: 1) Aux connections are "Normally Closed" (3 white leads tied together). Lever actuation "opens" the appropriate wire/connection). (( I have no clue how this would be used.)) 2) If you have the blue wire, you need to use the correct flasher module that has the indicator output pin 3) Warning: on most Signal-Stat steering column mounted units, using the 4-way flasher slide bar, disconnects the brake lights. Keep that in mind if driving with someone following too closely. enjoy, Tom M. diagram

When I was doing O/D I was based out of the Chicago area. Only place that would be worse would be NYC. This one was just shy of 16', 20 cyl EMD gen set 168,000 lbs, 14' wide

I agree, big loads are exhausting for me as I'm on edge the whole time Even if I can drive okay, there's always a lot of people in a urgent hurry around me, and we only have a tiny population compared to the U.S. Paul

That is amazing that a diesel isn't offered, so much more fuel efficient I wonder if a truck called be purchased in a neighbouring state and then registered in California ? Paul

Done a few 16'+ loads myself and they wear you out more than anything. As I said, never seen something like your Drake, looks interesting.
