From track-shoe pre-tension to slew-bearing rebuild — Caterpillar keeps earthmoving and aggregate fleets earning on the haul road with a 250 / 500 / 1,000 hour cadence and mean-time-to-repair under 18 hours.
Hydraulic flow test, slew-bearing torque audit and pilot-pressure baseline logged before the excavator leaves the yard — warranty starts with numbers, not a handshake.
Undercarriage tension, Tier 4 Final emissions audit and boom pin & bushing rotation on a 250 / 500 / 1,000 hour cadence matched to your haul-road kilometers.
Cylinder reseal, final-drive swap and cab vibration calibration at 8,000 hours — keeps residual value above wholesale book for fleet renewals.
Five numbered steps every equipment manager recognizes from quarry and highway maintenance plans.
Track-shoe pre-tension and pilot-pressure baseline logged for warranty and commissioning packs.
Hydraulic-return filter swap and oil sample to an ISO 4406 cleanliness lab.
Engine, hydraulic and final-drive oils replaced; slew ring re-greased under load.
Boom and arm pin clearance gauged; cab ROPS torque audited against factory limits.
Undercarriage rebuild, cylinder reseal and on-site machine reactivation with acceptance checklist.
We benchmark undercarriage wear, hydraulic cleanliness and Tier 4 emissions against Caterpillar reference contractors running similar haul-road kilometers and dig cycles. Bring fleet size, equipment class and average hours per month — we return a prioritized PM calendar within five working days.
Service contracts can tier mass-earthworks fleets separately from foundation crews so undercarriage rebuilds and hydraulic reseals align with each duty cycle instead of a single calendar date.
