Komatsu HD680-2(S/N 1002-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu HD680-2 (S/N 1002-UP) is a rigid-frame, mechanical-drive haul truck in the roughly 85-ton class, rated for about 68,000 kg (150,000 lb) of payload. It is powered by a Cummins VTA1710-C800, a turbocharged, water-aftercooled V12 diesel displacing 28.0 L (1710 cu in) and rated at 578 kW (775 hp) at 2100 rpm, driving through a mechanical powershift transmission and torque converter rather than electric wheel motors. Komatsu built the HD680-2 in low volume during the late 1970s through the 1980s, positioning it below the larger HD780-1 and above the HD465-2 in Komatsu's rigid-truck lineup of the era. All three shared the same VTA28-family Cummins engine, and the same power unit was also used in the D455A-1 crawler dozer. The truck rode on 24.00-35 tires and carried a dump body rated near 44 m3 (58 cu yd) heaped and about 32 m3 (42 cu yd) struck. No factory-documented engine-control module or diagnostic fault-code system existed on this generation; monitoring was handled through mechanical gauges and warning lamps, consistent with the PT (pressure-time) mechanical fuel system on the VTA1710-C800.
Komatsu offered the HD680-2 as a single mechanical-drive configuration through its production run rather than issuing distinct engine or drivetrain tiers within the -2 series, and no confirmed direct successor model has been documented for this specific S/N 1002-UP range. Its relevance in today's used and parts market comes less from unit volume, since original production was small, and more from parts commonality: the VTA1710-C800 engine, PT fuel system components, and driveline hardware overlap with the HD780-1, HD465-2, and D455A-1, so working examples and salvage units support a wider parts pool than the HD680-2 badge alone suggests. Buyers sourcing parts for this truck should expect a mechanical, pre-electronic platform where wear items (fuel pump, injectors, turbocharger, final drives, brake bands) drive most of the aftermarket demand, and should verify serial-range fitment against the shared-engine sibling models before ordering.

Servicing the HD680-2(S/N 1002-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Track engine health on the VTA1710-C800 with scheduled oil sampling, since there is no onboard diagnostic system to flag wear early. Pair oil analysis with coolant testing for the aftercooled circuit and periodic torque converter/transmission oil checks. Because the mechanical PT fuel system has no electronic fault logging, watch fuel filter change intervals and water-separator drains closely as leading indicators of injector and pump wear before failure.
Corrective & Common Repairs
Expect wear-driven repairs on the PT fuel pump and injectors, turbocharger shaft bearings, and final drive wheel bearings given the truck's mechanical-drive design and age. Brake bands and discs in the mechanical service brake system are common replacement items under heavy haul-road duty. Hoist cylinder seals and body hinge pins also see regular attention on high-cycle dump applications typical of this class.
Overhaul & Rebuild Points
Major rebuild points on the HD680-2 center on the VTA1710-C800 inframe or top-end overhaul, torque converter and powershift transmission rebuild, and final drive planetary reconditioning. Frame rails, dump body structure, and hoist trunnions warrant fatigue inspection at extended-hour milestones given the truck's age and the stresses of an 85-ton payload class over decades of service.
Seasonal & Environment Servicing
Cold-climate starts on the mechanical PT-fuel VTA1710-C800 benefit from ether-assist or block-heater use, since there is no electronic cold-start strategy to compensate. In hot, dusty mine environments, radiator and aftercooler cores need frequent cleaning to prevent overheating under sustained load. Tire and rim inspection on the 24.00-35 tires should account for heat buildup on long haul cycles in warm climates.

| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Engine oil pressure warning lamp + buzzer | Engine oil pressure has dropped below the safe minimum | Low oil level, worn oil pump, clogged suction screen, or failed pressure switch | Stop engine immediately, check oil level and look for leaks before restart |
| Engine coolant temperature warning lamp + buzzer | Engine coolant temperature has exceeded the safe operating range | Low coolant level, blocked radiator core, slipping or failed fan drive, or thermostat stuck closed | Idle down, verify coolant level once safe, inspect radiator and fan drive before returning to load |
| Engine coolant level low lamp | Coolant level in the surge tank or radiator has dropped below the sensor float | External leak at hoses, water pump, or radiator seams; internal leak into the block | Shut down, inspect cooling system for leaks, top up and pressure test before returning to service |
| Torque converter oil temperature warning lamp | Torque converter/transmission oil temperature is above the safe limit | Low transmission oil, plugged oil cooler, sustained lugging or stall-speed operation on grade | Reduce load/throttle, let temperature drop, check oil level and cooler airflow |
| Brake (retarder) oil temperature warning lamp | Wet-disc brake or retarder oil is overheating | Excessive retarder use on long grades, low brake oil level, or restricted brake oil cooler | Ease off retarder use, allow cooling, check brake oil level and cooler condition |
| Charging system (alternator) warning lamp | Battery is not receiving charge from the alternator | Broken or slipping drive belt, failed alternator, or loose/corroded wiring connection | Check belt tension and wiring at first safe stop; do not shut down engine if restart is doubtful until inspected |
| Air cleaner restriction indicator | Intake air filter element is loading up and restricting airflow to the turbocharger | Dusty operating conditions, overdue filter service | Service or replace air filter element, reset restriction indicator |
| Parking brake applied lamp | Parking brake is engaged | Operator-applied or system default with engine off/low air-hydraulic pressure | Confirm release before attempting to move the truck; verify brake system pressure if lamp will not clear |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
HD680-2(S/N 1002-UP) attachments & work tools
Dump body
Rigid mechanical-drive haul truck in the roughly 68-tonne (about 75 US ton) payload class, factory dump body only — heaped capacity around 44 m3 (57.6 cu yd) and struck capacity around 32 m3 (41.9 cu yd), with dump angle near 65 degrees. Exact figures vary by body style ordered (rock vs. general/coal service) and should be confirmed against the build-specific spec sheet for this serial range.
Tailgate and sideboards
Standard rigid-frame haul trucks in this class run with or without a hinged tailgate depending on material handled; bolt-on aftermarket tailgate and sideboard kits (no-weld, outrigger-mounted) are built for Komatsu rigid-frame trucks of this size, with sideboard height added in small increments to raise volumetric capacity. Fitment for this specific dash-series and serial range should be verified with the tailgate supplier, since published retrofit lists mainly reference later HD-series generations.
Load ejector / rear-eject system
Aftermarket rear-eject panel systems are offered for Komatsu rigid-frame haul trucks to clear sticky or wet material that will not dump cleanly by gravity alone; the overlapping ejector plates slide down and hang clear of the body opening. These are add-on kits fitted to the existing dump body, not a factory work-tool change.
Body liner and wear protection
Bolt-in or weld-on wear liner packages and body seal/cushion-pad kits are common options across this haul-truck weight class to protect the body floor and sides from abrasive rock loading and reduce spillage and noise. No model-specific liner spec was found for this serial range — treat as a dealer-fit option.
Tires
Factory tire fitment is 24.00-35, available in both bias-ply and radial (24.00R35) construction from tire suppliers serving this model; no tire-chain option was documented for this size class in available sources.
Mining/quarry duty options
Komatsu mechanical rigid dump trucks in this size and era commonly offer dealer-installed options such as centralized auto-lubrication, fire suppression, a spare rim/wheel carrier, and additional work lighting for mine-site duty. None of these were confirmed as documented specifically for this serial range, so verify availability with a Komatsu dealer before ordering.
Attachment/coupler system
This is a fixed-body haul truck, not a tool-carrier; there is no quick-coupler or interchangeable work-tool system. Body and guarding changes are bolted or welded to the frame/body by the dealer or an aftermarket body builder rather than swapped in the field.

A Cummins VTA1710-C800, a turbocharged, water-aftercooled V12 diesel displacing 28.0 L (1710 cu in) and rated at 578 kW (775 hp) at 2100 rpm.
What is the operating weight of the Komatsu HD680-2?
It is an approximately 85-ton class rigid haul truck rated for about 68,000 kg (150,000 lb) of payload, with a dump body sized near 44 m3 (58 cu yd) heaped.
What replaced the Komatsu HD680-2?
No direct successor model is confirmed in available documentation for this serial range. Confirm current-generation replacement options with a Komatsu dealer.
What HD680-2(S/N 1002-UP) owners discuss
Is there much owner or operator discussion of the HD680-2(S/N 1002-UP) online?
Honestly, very little. This was a low-volume, Japan-market-heavy haul truck built mainly through the late 1970s into the mid-1980s, and it never spread widely outside a handful of regions. Dedicated threads or write-ups tied specifically to this serial range are not out there. What follows below leans on general community experience with the same Cummins PT-fuel V12 family and with mechanical-drive rigid haul trucks of similar class and vintage — treat anything not explicitly tied to this truck as background context, not HD680-2-specific fact, and confirm details against your own machine and dealer.
What powertrain quirks come up most with the Cummins PT-fuel V12 in this class of truck?
Operators of PT-pump Cummins engines from this era consistently flag the same pattern: these engines are mechanically governed with no electronic controls, so performance complaints (hard starting, surging, low power, smoking) trace almost every time back to fuel-side issues — a weak or worn PT pump, plugged filters, air leaking into the suction side, or an overhead (valve/injector) adjustment that has drifted out of spec. Fuel cleanliness matters more on these than on common-rail engines; water or debris in the fuel degrades the PT pump and injectors faster than people expect. Injector O-ring and seal leakage is the most commonly reported wear item, usually cured by pulling injectors for cleaning and reseating rather than wholesale replacement. Have your dealer verify PT pump calibration and overhead settings rather than chasing symptoms with parts swaps.
What hydraulic behavior is typical for the dump body hoist and steering circuit on trucks this size?
Not documented for this exact serial range, but rigid-frame mechanical-drive haul trucks of this era and tonnage share a common failure pattern: cylinder seal weep at the hoist and steering rams as the machine ages, slow or spongy hoist response when hydraulic oil is cold or contaminated, and pump wear showing up first as reduced hoist speed under full load rather than total failure. Routine oil analysis and seal inspection catch most of this before it becomes a breakdown. Have your dealer verify hoist and steering cylinder condition and hydraulic pump output on any machine you're evaluating.
What undercarriage or tire wear patterns should be expected on a truck like this?
This is a rigid, rear-drive haul truck, not a tracked machine, so there's no undercarriage in the dozer sense — wear shows up in tires, wheel bearings, and frame/suspension mounts instead. For haul trucks in the 60-70+ tonne payload class, the consistent community theme is uneven tire wear driven by haul-road condition and loading balance rather than the machine itself: heat cracking and shoulder wear on tires run at sustained high loads on rough or poorly maintained roads, and accelerated wear when a truck is habitually overloaded or run with mismatched tire pressures side to side. Frame and suspension mount cracking is also a known watch item on trucks this old, simply from cumulative fatigue cycles. Have your dealer verify frame, suspension mounts, and tire/rim condition before returning a used unit to service.
Are brakes and final drives a common wear concern on this class of mechanical-drive truck?
Yes, broadly. Community experience with mechanical-drive rigid haul trucks points to the brake pack and final drive as one of the highest-priority wear areas, especially on machines without a strong engine retarder — service brakes do more of the work slowing a loaded truck downhill, so pack wear accelerates. A recurring theme is that brake pack wear rate tracks directly with charge pump and cooling oil flow condition: if the charge pump is weak, brake cooling and release suffer and wear accelerates sharply, sometimes showing up first as vibration or a slow brake release rather than obvious pedal loss. This is safety-critical — have your dealer verify brake pack wear, charge pump output, and cooling oil flow before operating a used unit.
What electrical or sensor issues come up on a machine this old?
This generation of Cummins engine is mechanically governed with essentially no engine-management electronics — there's no ECM to fault-code. The one common speed-sensing component on engines of this family is a simple magnetic pickup feeding the tachometer, and the recurring complaint in the wider Cummins mechanical-engine community is erratic or dead tach readings traced to a fouled sensor gap, a loose mount, or a corroded/broken wire rather than sensor failure itself. Beyond that, "electrical issues" reported on machines this old are almost always basic: corroded connectors, tired grounds, and worn gauge senders, not anything specific to this model. Have your dealer verify wiring and connector condition rather than assuming a sensor is bad.
What should a buyer check before purchasing a used HD680-2(S/N 1002-UP)?
Given how few of these were built and how old the youngest examples now are, treat any used unit as a restoration-grade purchase, not a turnkey production asset. Priority checklist: (1) confirm the Cummins PT-fuel V12 starts, idles, and pulls load without smoking or surging, and get PT pump/injector condition verified rather than taking a seller's word; (2) inspect frame, suspension mounts, and wheel/rim condition for fatigue cracking; (3) check brake pack wear and charge pump function — this is the single most safety-critical system on a truck this size; (4) look for hydraulic cylinder seal weep at hoist and steering circuits and pull an oil sample if possible; (5) verify parts and service support with your dealer before committing, since this model's parts pipeline is thin and lead times can be long. Have your dealer do a full pre-purchase inspection and verify braking, steering, and frame integrity before the truck goes back into service.
