yeah that is Scarsella Brothers of Kent WA. Mack should have been paying them to do R&D work for them, we were working on a 9 Mil yard mass fill and working trucks 20 hours a day. About 3500 miles a week total on them and they bought at least 30 tractors and 10 dump trucks. The dump trucks were 2004s and the tractors were 2005s. We helped Mack so much do the the extreme amount of miles we were putting on them, and by also having two differnt platforms to help determine causes of problems. The local Mack dealer had 3 tractors that they simply used to rob parts off of in order to keep the fleet on the road, since most of the issues were warrentee anyway and in the end they bought them three anyway. I was amazing to me how consistant the failure of a certain part would be. For example the fan clutch issue, withing 5000 miles of each other (50,000-55,000) 75% of the fleet had the fan clutch fail. It was about a 10k spread for the coolant resivors. OMG and don't get me started on the injector fuel line cracks on the short lines that go into the injector. I swore we were going to burn one of the trucks down to the ground. They would crack and leak on the exhaust manifold. If left unseen, it would get so bad that it looked like a Nascar truck blowing an engine for all the diesel smoke coming out from under the truck. Would fill the cab with smoke too. I could always find those leaks early by just smelling my shirt at the end of the day, any exhaust leak or smoke from the cab will concentrate on your clothes. Good times, was strange to get use to the fact that the position of the driver was moved out toward the drivers side a few inches to widen the cab. You get so use to your own position in the lane that when you switch it up like that you end up keeping your body in the same place in the lane but now the truck is shifted over to the passenger side. Makes for some scary mirror checks till you get your landmarks reestablished.
Note that is a live petrolium pipeline supplying the aircraft hardstand that is cast in the CDF (controled density fill) that the excavor is trenching under. Not my idea of fun.
