rhasler Posted May 15, 2011 Share Posted May 15, 2011 Friday afternoon I had to make an emergency patch to the air inlet tube (the tube between the air cleaner housing and the turbo) of a GU713 with an MP7 engine. The issue was a small rubbed area about the size of a dime in the area where the air cleaner tube bends and twists away from the valve cover at the right front corner of the engine. Had enough time elapsed with the intake open the engine would have been dusted, requiring major engine repair and maybe even DPF replacement if the engine was passing enough oil into the exhaust stream. So what caused the hole to wear in the tube? The right side front cab mount is worn to the point that the cab is resting on the frame bracket that the isolator is bolted to, while the left side is still in decent shape. In other words, the cab is leaning over, much the same way that a chassis leans towards a weak spring, allowing the air cleaner tube to make contact with the valve cover. The cab mount is a fairly simple repair with the right tools, and is definitely cheaper than major engine repair. Quote "Mebbe I'm too ugly and stupid to give up!"
