Servicing the PC110R-1(S/N 2265010001-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA fluid analysis at every 500-hour interval to monitor engine wear metals and hydraulic oil particle counts. Check hydraulic fluid levels daily with cold oil on level ground, ensuring cylinders are retracted and boom extended. Monitor coolant SCA concentration at 500 hours to prevent corrosion. Track fuel dilution and viscosity changes in engine oil to predict turbocharger or piston ring wear before failure occurs.
Corrective & Common Repairs
Address abnormal pump noise by inspecting hydraulic oil levels and checking for air ingress in suction lines. Replace hydraulic return filters at 500 hours to prevent valve contamination. If the engine overheats, clean debris from radiator and oil cooler fins immediately. Inspect final drive oil for metal particles indicating gear wear. Replace worn track shoes and adjust tension to prevent undercarriage stress and premature roller failure.
Overhaul & Rebuild Points
Perform comprehensive structural inspections on boom and stick welds at 1,000-hour intervals. Change swing machinery oil at 1,000 hours and inspect swing circle bearings for play. At 2,000 hours, replace hydraulic system oil and flush the cooling system. Inspect turbocharger blades for damage. Evaluate undercarriage wear components including sprockets, idlers, and rollers; replace track chains when elongation exceeds limits to protect final drives and rollers.
Seasonal & Environment Servicing
Switch to ASTM D975 No. 1 diesel oil for temperatures below -10°C; use No. 2 oil for temperatures above -10°C. Check DEF levels regularly on Tier 4 compliant units. Inspect battery terminals and load capacity in cold weather to ensure reliable starting. Drain water from the fuel separator daily in humid or cold conditions to prevent fuel line freezing. Verify hydraulic hose flexibility and clamp integrity to prevent cold-weather cracking or leaks.

PC110R-1(S/N 2265010001-Up) attachments & work tools
Buckets
Factory specifications list a standard capacity range of 0.09–0.4 m³ (0.12–0.53 cu yd). Typical widths for this class vary by configuration, generally spanning 600–1000 mm (24–39 in). Pin-on mounting is standard, with quick-coupler compatibility dependent on aftermarket adaptors.
Hydraulic hammers
The machine falls within the 10–11 tonne operating weight class. Compatible breaker weights typically range from 1,000 to 2,000 kg (2,200–4,400 lb). The swing circuit pressure is rated at 21.5 MPa (215 bar), requiring a hammer kit matched to this medium-pressure standard.
Quick couplers
Compatible with hydraulic and mechanical couplers rated for the 10–11 tonne class. Steelwrist lists automatic couplers and tilt-rotor couplers (such as the XTR10 or X14) as compatible options for the PC110R series.
Thumbs/grapples
Aftermarket suppliers list mechanical ripper and thumb kits for the 0–33 tonne range, which includes this model. Powered work tools such as finger grapples and sorting grapples are available for the 2–26 tonne class.
Rippers
Mechanical ripper attachments are listed for the 0–33 tonne excavator range. Single-shank or multi-shank configurations are available from aftermarket manufacturers for this midi-class machine.
Hydraulic-kit notes
The swing circuit operates at 21.5 MPa (215 bar). Hydraulic hammers and high-flow tools require a specific kit to interface with this pressure rating. Komatsu specifies Komatsu EO, TO, or AXO fluids for the hydraulic system.
