Low Cost Maintenance

Worldwide service delivers ease of maintenance and simplifies the servicing routine. Hydraulic tappets, multi-vee belts, "no ash service" aftertreatment, and 500-hour oil change intervals enable low-cost maintenance. Many service items have a choice of location on either side of the engine to enable choice of service access. The S·O·SSM program is available from your Cat dealer to determine oil change intervals and provide optimal performance.

Quality

Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.

Tier 4 Interim, Stage IIIB Aftertreatment Features


Regeneration. Passive regeneration completely transparent to the operator.


Mounting. Extensive range of inlets and outlets, as well as remote off- and on-engine installations, provide flexibility for many installations.
Service. Service-free DPF for the emissions life of the engine.
