System Notes — AIR INLET AND EXHAUST SYSTEM
The air inlet and exhaust system covers the air cleaner housing and elements, intake piping, turbocharger, aftercooler, exhaust manifold, turbo mounting hardware and gaskets. It delivers clean, dense air and carries hot gas away. On this group, the two dominant failures are dust ingress and heat cycling: a leaking intake joint lets unfiltered air straight into the cylinders and dusts the rings in a few hundred hours, while exhaust manifold and turbo flange gaskets crack from repeated heat cycles and start whistling or sooting. Parts are replaced when boost drops, the intake tract shows dust trails past the filter, or a soot streak appears at a joint.
System Notes — OPERATOR STATION
The operator station covers the cab structure, seat and suspension, glass, wipers, door hardware, pedals, joysticks, armrests, HVAC ducting and the interior trim. It is the group that decides how tolerable a ten-hour shift feels. Wear here is driven by daily entry and exit, sun exposure and dust: seat suspensions sag, door struts lose charge, wiper linkages seize, and rubber seals harden until the cab leaks in rain. Parts in this group are replaced when a control feels vague, a latch no longer holds, or the cab no longer keeps dust and water out — small items, but the ones operators complain about first.
