This tractor pulls 50,000# garbage to landfill, 470 miles return. Fuel economy is not great, and driver complains that he has to drop gears to get up hills, it doesn't seem to have power.
Specs on truck
- Engine AC460P -ASET 460 hp - TRANSMISSION - 18 SP FULLER - RTL-016918B - Rear axle - RT46-164EH - 4.10 - Suspension - AL461 60" SPACING - Front tire size - 12R22.5 , 484 revs per mile - rear tire size - 11R22.5, 495 revs per mile - top gear ratio - .73 ratio
It has 168,000 miles, and 8700 hours. Lots of hours to pack garbage in compacting trailer with wetline . Recent new EGR, manifold bolts, injectors, turbo, and reflash by Mack dealer. Doesn't make a big difference.
We just can't believe this truck can't do better. We think it's just short on enough power, and would love to get better economy. I am asking the forum, what experience do they have with these tractors, how to boost them up, and what kind of fuel economy should we expect? Any thoughts would be appreciated.
