System Notes — SERVICE EQUIPMENT AND SUPPLIES
This group covers the equipment and consumables used to service the machine rather than to run it: filter wrenches and service tools, drain and fill hardware, grease fittings and couplers, sight gauges, sampling valves, and the small hardware that makes routine maintenance possible without improvising. Items here are replaced when they no longer seal, no longer hold a setting, or when a stripped fitting turns a ten-minute service job into a two-hour one. Keeping the correct part number on hand matters more than the unit price, because a missing grease coupler usually means a missed lube point.
System Notes — GENERATORS
The generators group covers the alternator end of a generator set: stator, rotor, exciter, bearings, coupling disc, terminal box and the voltage regulation hardware. It converts engine rotation into electrical output at a held voltage and frequency. Bearing wear and insulation degradation are the two long-term concerns — a bearing that starts to rumble will eventually seize and take the rotor with it, while moisture and heat slowly break down winding insulation. Parts in this group are replaced when vibration rises, when insulation resistance falls on a megger test, or when output voltage becomes unstable under load.

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.
