Service Schedule Walkthrough

Service Built for the Next 8,000 Hours On-site

From track-shoe pre-tension to slew-bearing rebuild, Kobelco keeps your earthmoving fleet earning on the haul road with 250h / 500h / 1000h intervals and mean-time-to-repair under 18 hours on contracted sites.

Why service intervals matter more than brochure horsepower

Equipment managers rarely lose a season because a mid-class excavator lacked a few kilowatts on paper. They lose seasons when undercarriage wear is misread, hydraulic ISO 4406 samples are skipped, or final-drive parts sit three countries away from the haul road. Kobelco service planning starts with the same numbers your bid book already tracks: operating weight class, average digging depth, breakout force demand and weekly haul-road kilometers.

Field service engineers carry commissioning sheets that record pilot pressure baselines, track-shoe pre-tension and slew-bearing torque before the first production cut. Those values become the reference for 250-hour, 500-hour and 1,000-hour checks. When a contracted site reports a stoppage, dispatch targets a mean-time-to-repair under eighteen hours using parts staged at quarry-belt hubs rather than waiting on factory backorders.

For fleets mixing Kobelco excavators with crawler cranes or loaders, we align fluid-swap windows so a single site visit can cover engine oil, hydraulic oil and final-drive oil without stacking multiple mobilizations. That discipline is what keeps residual value above wholesale book when the machine reaches the 8,000-hour rebuild gate.

Three Service Layers That Match Contractor Cadence

Procurement managers and fleet desks use the same interval language our FSEs carry on every site visit.

Pre-delivery Commissioning

Hydraulic flow test, slew-bearing torque audit and pilot-pressure baseline before the machine leaves the yard. Warranty paperwork references measured values, not estimated ranges.

Scheduled Field PM

Undercarriage tension, Tier 4 Final emissions audit, boom pin and bushing rotation on a 250 / 500 / 1000 hour cadence matched to your haul-road kilometers.

Major Overhaul & Rebuild

Cylinder reseal, final-drive swap and cab vibration calibration at 8,000 hours — protecting residual value above wholesale book for contractor fleets.

Service Interval Timeline

Five numbered steps that equipment managers can drop straight into a fleet PM calendar.

  1. 01

    0h Pre-delivery

    Track-shoe pre-tension and pilot-pressure baseline logged for warranty and first-cut readiness.

  2. 02

    250h First Check

    Hydraulic-return filter swap and oil sample submitted to an ISO 4406 cleanliness lab.

  3. 03

    500h Fluid Swap

    Engine, hydraulic and final-drive oils replaced; slew ring re-greased under load profile notes.

  4. 04

    1000h Major PM

    Boom and arm pin clearance gauged; cab ROPS torque audited against factory tables.

  5. 05

    8000h Rebuild

    Undercarriage rebuild, cylinder reseal and on-site machine reactivation with post-rebuild dig cycle.
