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.

Genuine CAT vs direct replacement — what is the difference?
Genuine CAT covers three factory lines: New Genuine, Cat Reman (core exchange with core charge) and Cat Classic (brand-new economy line). OEM-equivalent direct replacements are non-CAT parts; grade and warranty are confirmed in the quotation.
