Can't get them though, N/A from cummins gotta go aftermarket. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70593-if-you-had-the-opportunity-to-redesign-the-mack-chassis-and-the-mp-engines-what-would-you-change/page/10/#findComment-516620 Share on other sites More sharing options...

EM6285 Posted December 2, 2022 Share Posted December 2, 2022 (edited) MACK TRUCKS also needs to do an UPGRADE on its headlamps. Replaced all of them... On all 4 MACK GU813s But, they still are rubish. Poorly built headlamps from TYC. They get foggy, yellowish and tarnished so easy and they get water inside.

Onyx610 Posted December 2, 2022 Share Posted December 2, 2022 We haven’t had any issues that you’re seeing with the headlights.

Buy some “Off” insect repellent with “Deet” . Spray on headlights and wipe off. Makes them like new. Our company won’t buy new headlight housings so we use Off. It must be Off with Deet though.

mdixon Posted December 2, 2022 Share Posted December 2, 2022 (edited) Some lined up after today's runs, not all of were back yet. I'd change the clutch setup on these CXU613s. Trying to adjust the free play on a bound up linkage sucks, and changing a broken air shaft roadside is awful.

EM6285 Posted December 3, 2022 Share Posted December 3, 2022 Here is the thing I HATE most on new MACK TRUCKS... That bump-forward center console at the dash. Very uncomfortable ride for a 3 men crew. Whoever sits at the middle gets the worst ride. MACK TRUCKS needs to fix this "lump" on their dash-board design... And why MACK TRUCKS needs to cram 1/4 of the engine under the cab? I wish they will go to a flat firewall cab structure with ALL THE ENGINE IN FRONT OF IT and not part of the engine under the cab.
