Komatsu H455S(S/N G15005)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu H455S is a large hydraulic mining shovel in the roughly 480-490 tonne operating weight class, built by Komatsu Mining Germany (the former Demag mining shovel line acquired by Komatsu). It is powered by twin Cummins KTTA38-C diesel power packs delivering a combined output near 1,667 kW (2,236 hp) at 1,800 rpm, driving a fully hydraulic front-shovel loading configuration with a bucket capacity in the 25 to 30 cubic metre range depending on heap ratio and bucket fitted. The H455S sits at the top end of Komatsu's Demag-heritage shovel range from the late 1990s into the 2000s, built for high-production overburden and ore loading into large rigid-frame haul trucks. It shares its size class and much of its digging geometry with the Komatsu PC5500, reflecting the transition period when Demag-designed shovels were rebadged under the Komatsu name before the PC5000/PC5500 series took over as the standalone Komatsu-engineered successor.
Across its production run the H455S carried over the Demag-era twin-Cummins powertrain and shovel-front geometry with running updates to hydraulics, electronic monitoring and undercarriage components rather than a full generational redesign; buyers should treat published operating weight and dimension figures as configuration-dependent, since counterweight, bucket size and undercarriage pad width all shift the numbers reported across specification sources. In today's used and parts market the H455S matters as a durable, still-working legacy mining shovel: mines running these units value the mechanical simplicity of the twin-diesel powertrain and the wide availability of common wear parts (track components, hydraulic seals, ground-engaging tools) even though it has been out of new production for years, and the type sits directly in the ownership history behind Komatsu's current PC5000/PC7000-class mining shovel lineup.

Servicing the H455S(S/N G15005) beyond the schedule
Predictive Maintenance and Fluid Analysis
Run scheduled oil analysis on both Cummins KTTA38-C power packs and the shared hydraulic system to catch bearing, liner and pump wear before failure; trend coolant condition given the dual-engine cooling load. Track swing gear and final drive oil samples separately since wear metal signatures differ between the two travel final drives. Use onboard monitoring data from both engines to flag boost and exhaust temperature drift, a common early warning on twin-engine power packs pulling uneven load.
Corrective and Common Repairs
Expect recurring work on hydraulic cylinder seals and main pump wear given the continuous high-pressure cycling of a shovel this size, plus periodic swing motor and swing bearing attention from constant slew-and-dig cycling. Twin-engine coordination issues (uneven fueling, mismatched boost) show up as power loss or vibration and usually trace to one power pack, not both. Undercarriage pin and bushing wear from loading-cycle track loads is routine and should be measured against wear limits, not just visually inspected.
Overhaul and Rebuild Points
Major rebuild points center on the twin Cummins KTTA38-C power packs (liners, injectors, turbochargers) on an hour-based schedule independent of the hydraulic system overhaul cycle. Swing bearing and swing gear replacement is a planned major job on high-hour units, as is main pump and swing motor exchange once oil-analysis trends show consistent wear metal increases. Structural inspection of the boom foot, house frame and counterweight mounts at overhaul intervals catches fatigue cracking before it becomes a welded structural repair.
Seasonal and Environment Servicing
In cold climates, both power packs need block heaters or coolant pre-warm before start, and hydraulic oil viscosity grade should match ambient swings since a shovel this size holds a very large hydraulic oil volume that is slow to warm. In hot, dusty pit environments, radiator and hydraulic cooler cores need frequent cleaning to protect the twin-engine cooling system, and cab and engine bay air filtration needs shortened service intervals. Wet-season pit conditions call for closer track and final drive seal inspection given the machine's operating weight and ground loading.

H455S(S/N G15005) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| ENG OIL PRESSURE LOW (shutdown) | Engine oil pressure has dropped below the safe operating threshold and the protection system trips an automatic shutdown. | Low oil level, worn oil pump, clogged suction screen or filter, or a faulty pressure sender. | Check oil level and filter condition before restart; verify the pressure sender/switch reading against a mechanical gauge. |
| ENG WATER TEMP HIGH (shutdown/derate) | Jacket water temperature has exceeded the safe limit; engine shuts down or derates to prevent damage. | Low coolant, blocked radiator core, slipping or failed fan drive, or a stuck thermostat. | Check coolant level, inspect the radiator core and fan drive belt, verify thermostat operation. |
| ENGINE OVERSPEED (shutdown) | Engine rpm exceeded the governor's set limit and the mechanical protection system trips a shutdown. | Governor linkage fault, sudden loss of load, or fuel rack malfunction. | Inspect governor linkage and PT fuel pump before attempting restart; do not restart until cause is found. |
| LOW COOLANT LEVEL | Coolant level sensor indicates the system is below minimum safe level. | External leak, hose or gasket failure, or evaporation loss. | Inspect for visible leaks, pressure test cooling system, top up with correct coolant mix. |
| HYD OIL TEMP HIGH | Hydraulic reservoir or return-line temperature has exceeded the normal operating range. | Fouled hydraulic oil cooler, low hydraulic oil level, or sustained high-load operation. | Check cooler fins for debris, verify oil level, check main relief valve settings. |
| HYD FILTER RESTRICTION | Bypass/clogging indicator shows the hydraulic filter element is loading up and nearing bypass. | Dirty or saturated filter element, contaminated hydraulic oil. | Replace the filter element; sample oil if restriction recurs quickly. |
| CHARGE/ALTERNATOR FAULT | Battery charge warning indicates the charging circuit is not maintaining system voltage. | Slipping or broken drive belt, failed alternator, loose or corroded connections. | Check belt tension and condition, test alternator output, inspect wiring connections. |
| LOW FUEL PRESSURE | PT fuel pump inlet or supply pressure has dropped below normal. | Clogged fuel filter/strainer, air in the fuel system, restricted supply line. | Check and replace fuel filters, bleed the fuel system, inspect supply lines for restriction. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
H455S(S/N G15005) attachments & work tools
Primary work tool - front shovel loading bucket
Factory-configured as a front-shovel loading tool for face loading in surface mining. Heaped bucket capacity runs roughly 25.0 m3 (32.7 yd3) at a 1:2 heap ratio up to about 30.0 m3 (39.2 yd3) at 1:1, with bucket width near 4.4 m (14 ft 5 in). Exact capacity varies by bucket style and material density selected for the application.
Bucket variants by material
This size class offers heavy rock buckets for blasted, abrasive rock (narrower profile, reinforced wear package) alongside higher-capacity general-duty or overburden buckets for softer, less abrasive digging. Coal/soft-material buckets with a wider, shallower basket are also used in this shovel class for low-density loading. Bucket choice is matched to material density and swell factor, not interchangeable without a capacity trade-off.
Backhoe / mass-excavation configuration
Shovels in this weight class can in some cases be field- or factory-converted to a backhoe/mass-excavation front for below-grade digging on shorter benches, as an alternative to the standard face-shovel front. Backhoe availability and kit details for this specific unit are not confirmed in factory literature for this serial range - verify with your dealer before ordering.
Ground engaging tools (GET)
Buckets use a bolt-on or forged tooth-and-adapter system with replaceable lip shrouds and side-wear protectors sized for high-abrasion rock loading. Tooth systems in this class are typically hammerless bolt-on designs; the exact GET family fitted to this serial is not documented for this exact serial range - confirm current GET spec with your dealer.
Mounting / coupler system
Buckets are pin-and-bushing mounted directly to the stick, not fitted with a hydraulic quick coupler. Quick-change couplers are a feature of smaller construction-class excavators; large mining shovels in this weight class keep a fixed bucket-to-stick pin joint because attachments are swapped infrequently during scheduled service, not daily.
Hydraulic arrangement notes
Twin diesel engines drive separate hydraulic pump/circuit sets sized for the boom, stick, and bucket cylinders needed to cycle a bucket in the 25-30 m3 class. No auxiliary hydraulic attachment kit is required for the standard bucket front since it is pin-mounted rather than hydraulically actuated; any hydraulically operated tiltable or crusher-style bucket would need dedicated auxiliary circuit provisions not confirmed for this unit.
Guarding and factory protection options
Mining-duty guarding typical for this shovel class includes reinforced bucket floor and sidewall wear liners, cab FOG/FOPS guarding for rock-loading exposure, and undercarriage/counterweight guarding. Specific factory-optional guarding fitted to this serial is not confirmed - verify configuration with your dealer.

H455S(S/N G15005) serial number reference
The identification plate sits on the shovel's main frame near the cab, on the platform structure below or beside the operator's cab depending on running change; some units carry a stamped number under a riveted or adhesive Komatsu ID decal. Read the plate as model designation followed by the serial number (for example H455S, S/N G15005); the leading G is part of the serial string itself rather than a separate coded prefix, and Komatsu's home-market 3-character PIN prefix scheme used on excavators and dozers does not apply to this Demag-heritage shovel line.
| Prefix | Identifies | Notes |
|---|---|---|
| G | H455S Demag-heritage mining shovel serial format | Serial numbers on this shovel run as a single G-prefixed number (e.g. G15005), not a distinct 3-character PIN prefix like Komatsu's home-grown construction lines. No dealer or parts-catalog source ties a separate 3-character code to this range beyond the G-prefix itself. Confirm with dealer if a finer sub-range split exists for this serial. |
Frequently asked questions
What engine does the Komatsu H455S(S/N G15005) use?
It runs twin Cummins KTTA38-C diesel power packs with a combined rated output near 1,667 kW (2,236 hp) at 1,800 rpm, a twin-engine arrangement typical of this Demag-heritage shovel class.
What is the operating weight of the Komatsu H455S(S/N G15005)?
Operating weight falls in the roughly 480 to 490 tonne (about 1.06 to 1.08 million lb) class, with the exact figure varying by counterweight, bucket size and undercarriage configuration fitted.
What replaced the Komatsu H455S?
The H455S sits in the size class directly ahead of the Komatsu PC5500, which shares similar digging geometry and became the standalone Komatsu-engineered successor as the Demag-heritage shovel line was folded into Komatsu's own PC5000/PC5500 mining shovel range.
What H455S(S/N G15005) owners discuss
What engine does the H455S(S/N G15005) use, and is the twin-engine layout normal?
This is a Demag-heritage large hydraulic mining shovel, a lineage later carried forward under Komatsu's PC5500 designation. Factory spec sheets for this generation list two turbocharged 12-cylinder Cummins KTTA38-C diesels driving the pump distributor gear through flexible couplings, combined output around 1668 kW (2236 hp) at 1800 rpm. Twin-engine operation is standard for this machine class, not a fault condition. Drivetrain vibration or uneven load sharing between the two engines points to worn couplings or mounts, not normal running behavior. Have your dealer verify engine coupling and mount condition before returning the machine to service.
How much does the H455S(S/N G15005) weigh and what bucket size does it carry?
Operating weight for this class runs close to 490 t (about 1,080,000 lb). Bucket capacity varies by configuration: spec sheets show a heaped capacity in the high-20s of cubic meters (roughly 28 m3 / 36.7 yd3), with other published figures ranging from about 25 to 30 m3 depending on heap ratio and whether the front is set up as a shovel or backhoe dipper. Treat any single published bucket number as a starting point, not a guarantee, since front configuration and site material density both move it.
What hydraulic quirks do owners/mechanics report on this shovel class?
Field reports describe seal weeping at main pump flanges and charge-pump connections as a common leak point, and it is often traced back to throttle valve adjustment rather than a bad seal outright. Overheating shows up when cooling packages get clogged with mine dust, so keeping cooler cores clear and fluid topped off matters more than on smaller machines. Hydraulic reservoir capacity on this class runs roughly 3,800 L (1,000 gal), large enough that a slow leak can go unnoticed for a while before a low-level warning trips.
What undercarriage wear pattern is typical for a machine this size?
This shovel class runs heavy track chain with large-diameter pins and rollers built for the load. Wear tracks with ground conditions more than raw hours: uneven or rocky benches accelerate roller and pad wear compared to graded haul roads. Uneven wear side to side across the track gauge is read as a grade or alignment issue, not normal aging. Undercarriage condition should be budgeted as a recurring inspection item on any unit pulled out of an active pit rather than treated as a one-time check.
What engine quirks come up for this Cummins KTTA38-C series specifically?
Large KTA/KTTA38-family diesels are known in the field for injector fouling and carbon buildup when run at light load or extended idle, a pattern common on shovels sitting between truck spots. Reduced power complaints on this engine family usually trace back to turbo boost loss, worn injectors, or restricted fuel lines rather than a single root cause, so a power complaint needs each of those ruled out in turn. Regular oil and fuel filter service, plus minimizing unnecessary idle time, keeps fouling in check.
What electrical or sensor issues come up on this platform?
Detailed sensor fault histories for this exact serial range are not well documented in public sources. Owners of comparable large Komatsu hydraulic excavators most often report pressure-sensor and solenoid faults traced to corroded connectors or dirt-contaminated hydraulic oil rather than outright module failure, and harness wear is a recurring theme on high-hour machines across the platform. Have your dealer run a full diagnostic scan of the machine monitor and control system before purchase or after any fault lamp event.
What should I check when buying a used H455S(S/N G15005)?
Inspect the boom-to-stick and stick-to-bucket weld areas for cracks, and run a magnet along the boom and side panels to check for filler used to mask a prior repair. With the engine off, check for play in the swing bearing and slew ring by hand, then swing the upper structure slowly in both directions and listen for grinding, clicking, or hesitation, signs of worn gear teeth or a failing bearing. Check both engine bays for oil leaks and turbo or injector blow-by, and confirm coupling alignment between the two engines and the pump distributor gear. Walk the full undercarriage for uneven roller and pad wear side to side. Given the scale and cost of any structural, engine, or hydraulic repair on a machine this size, have your dealer run a full inspection and diagnostic scan before you commit to purchase.
