Komatsu GD510R-1(S/N 15001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu GD510R-1 (S/N 15001-UP) is a 6-wheel, 6-cylinder motor grader in the roughly 23-24 tonne class, built to the shop manual issued in February 1993 covering the serial block 15001 and up. It runs a Komatsu S6D95L naturally aspirated diesel, 4.9 L displacement, rated 93 kW (125 hp) at 2500 rpm, with no electronic engine controller for this serial range; operator warnings surface through dash pictograph caution/action lamps and a buzzer rather than digital fault codes. Operating weight runs about 10,700 kg (23,590 lb) depending on tire and counterweight fitment, with a 227 L (60 US gal) fuel tank. The GD510R-1 sits inside a wider Komatsu grader family sharing one factory manual across the GD500, GD505, GD510, GD511, GD513, GD515, GD521, GD522, GD523, and GD525 model line, with the R-1 designation covering mechanical, non-electronic-engine configurations built alongside contemporary A-1 and other R-1 siblings of similar size.
Komatsu later moved this size class of grader to an electronically managed A-1 generation, exemplified by the GD511A-1 built roughly from the early 2000s into the 2010s, which added ECM-based engine control and digital diagnostics in place of the lamp-and-buzzer system used on the GD510R-1. That shift makes the GD510R-1 the last mechanical, non-ECM iteration in its size bracket before Komatsu standardized on electronic engine management across the grader line. In the used and parts market today, that simplicity is the draw: no engine control module to fail, straightforward pictograph-lamp diagnostics, and a drivetrain built around the widely produced 6D95/S6D95L engine family shared with other Komatsu excavators and wheel loaders of the era, which keeps engine parts sourcing easier than the grader-specific circle, drawbar, and tandem-drive components.

Servicing the GD510R-1(S/N 15001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
With no ECM or telematics on this serial range, fluid sampling is the main early-warning tool. Pull engine oil, transmission oil, tandem final drive oil, circle reverse gearcase oil, and hydraulic tank oil at scheduled changes and check for metal fines, which flag circle gear, tandem chain, or hydraulic pump wear before failure. Watch the S6D95L for blow-by and oil consumption since it runs naturally aspirated with no turbo to mask early wear. Log pictograph lamp and buzzer events manually since there is no fault code memory.
Corrective & Common Repairs
Recurring wear points on this grader are the circle drive gear and wear shoes, the drawbar ball-and-socket joint, blade lift cylinder seals, and the tandem (final drive) case for chain and seal leaks. The wheel lean cylinder and articulation hitch pins wear from grading vibration and need regular greasing to avoid play. Because there are no digital fault codes, electrical faults on this serial range usually trace to the pictograph lamp bulbs, wiring, or the buzzer circuit rather than a control module.
Overhaul & Rebuild Points
Major rebuild items are the circle drive motor and wear shoes once gear-tooth wear passes limit, the tandem case chain and sprockets, and the drawbar ball-and-socket at high hours. On the S6D95L, plan top-end work around the valve train, injectors, and injection pump as the naturally aspirated engine ages. Circle drive and blade lift hydraulic cylinders and the main hydraulic pump are the other common high-hour rebuild candidates on machines run in heavy grading duty.
Seasonal & Environment Servicing
In cold climates, check coolant concentration and drain fuel filter water more often since the naturally aspirated S6D95L has no turbo or glow-plug assist to help cold starts; keep battery electrolyte and terminals serviced as cranking load rises. In hot, dusty grading environments, shorten the air cleaner element and radiator/oil cooler fin cleaning interval, and grease the circle, drawbar, and articulation pivots more frequently since dust ingress accelerates wear on those points.

GD510R-1(S/N 15001-UP) attachments & work tools
Main moldboard (grading blade)
Standard moldboard measures approximately 3710 mm wide by 645 mm high (12 ft 2 in x 25.4 in), the primary grading work tool for this class of grader. Mounted mid-frame ahead of the tandem, forward of the operator, and hydraulically controlled for lift, side-shift and angle.
Circle and drawbar assembly
The moldboard rides on a rotating circle carried by a drawbar pivoting from the front frame; a circle reverse (drive) gear rotates the circle to set blade angle. This is the mounting/coupling system for the main blade rather than a quick-coupler, consistent with standard motor-grader practice for this size class.
Blade hydraulics
Blade lift is via hydraulic lift cylinders (one per side) with piping routed along the drawbar/front frame; a hydraulic control valve and levers in the cab operate blade lift, side-shift and circle rotation. Tilt/pitch adjustment is typically manual on graders of this class unless a powered-tilt kit is fitted.
Scarifier / ripper
A scarifier work tool (front- or rear-mounted, dealer-configurable) with its own hydraulic lift lever and control valve was offered for this class to break up compacted or frozen ground ahead of grading. Tooth count and spacing are not documented for this exact serial range — verify configuration with your dealer.
Front-mounted push/dozer blade
A front-mounted push blade is a common factory option on graders in this weight class for light dozing, stockpile and snow work, fitted ahead of the front axle independent of the main moldboard. Availability and dimensions for this specific serial range are not confirmed — verify with your dealer.
Snow removal equipment
Snow wing and snow plow attachments are offered regionally on R-series graders of this class for winter maintenance work, mounting to the front frame or side of the moldboard. Not documented for this specific serial range — treat as a regional/dealer-fitted option.
Tires
Standard fitment is 13.00-24, 8PR bias tires, consistent with the roughly 10.7-tonne (about 23,600 lb) operating class of this machine.
Guarding and cab options
Typical dealer-fitted options for this grader class include a ROPS/FOPS cab enclosure, front and rear work lighting, and blade-end wear/edge protection; specific factory option codes are not documented for this exact serial range.

GD510R-1(S/N 15001-UP) serial number reference
The PIN/serial plate on this grader is mounted on the chassis frame; some units also have the serial stamped into the frame rail itself. Read it as the full model code (GD510R-1) followed by the serial number - anything at or above 15001 falls in this documented range. Confirm exact plate placement with your dealer if it is not immediately visible. This generation of Komatsu grader does not use a Caterpillar-style 3-letter prefix; the model designation itself is the identifying code.
| Prefix | Identifies | Notes |
|---|---|---|
| 15001-UP | GD510R-1 sole production block | Only serial designation documented for this model in the Komatsu GD510/GD520-series shop and parts manual set (which also covers sibling ranges 10001, 20001, 30001, 50001, 55001, and 60001 belonging to other GD51x/GD52x models, not this one). No 3-character alpha PIN prefix scheme applies; model code GD510R-1 plus the serial start point is the full identity. Base engine is the S6D95L; a running change to the S6D95L-1Q calibration occurs at a later engine serial within this same chassis range - confirm the exact engine-serial break with your dealer. Minor piping running changes also occur early in the range (radiator piping splits around chassis serial 15089/15090; blade-lift cylinder line piping splits around chassis serial 15027/15028) - these do not represent a new prefix or model. |
Frequently asked questions
What engine powers the Komatsu GD510R-1 (S/N 15001-UP)?
A Komatsu S6D95L, a naturally aspirated 6-cylinder diesel of 4.9 L displacement, rated 93 kW (125 hp) at 2500 rpm. This serial range has no electronic engine controller. A later running change to an S6D95L-1Q calibration within the same serial block has been reported from a single source and should be verified with your dealer before ordering engine parts.
What is the operating weight of the Komatsu GD510R-1 (S/N 15001-UP)?
Approximately 10,700 kg (23,590 lb). Actual weight varies with tire selection, counterweighting, and attachment configuration, so treat this as a class figure rather than an exact machine weight.
What replaced the Komatsu GD510R-1?
Komatsu moved this size class to an electronically controlled A-1 generation, represented by the GD511A-1 built from roughly the early 2000s into the 2010s, which added ECM-based engine management and digital diagnostics in place of the GD510R-1's pictograph-lamp warning system.
What GD510R-1(S/N 15001-UP) owners discuss
How does the circle and moldboard hold up on a GD510R-1, and what wear pattern should owners expect?
Owners of this grader class report the circle assembly runs on wear strips/plates rather than a sealed bearing race, so play develops gradually at the circle rail and drawbar ball as the strips wear thin. Left unadjusted, that play shows up as blade chatter and slop in circle-turn response before it ever throws a fault. Periodic shimming or strip replacement is routine wear maintenance, not a defect. Moldboard cutting edges and end bits wear fastest in abrasive or rocky material and get rotated or flipped to even out wear before the base steel is exposed.
Are hydraulic circle-turn or blade-tilt problems common on this grader, and what usually causes them?
Community reports on this class of grader point to sluggish or jerky circle turn and blade tilt response tracing back to two things: contaminated or degraded hydraulic oil, and wear in the circle-turn motor or blade-tilt cylinder seals rather than the pump itself. Aggressive circle rotation against hard-packed material or turning under full blade load accelerates wear on the circle drive components. Routine oil and filter service on schedule resolves the majority of sluggish-response complaints reported by operators. Because loss of circle or lift control affects operator and bystander safety, have your dealer verify hydraulic pressures and circle-drive condition before returning the machine to service.
What engine quirks show up on the S6D95L-1 that powers this grader?
The S6D95L-1 is a widely used Komatsu mid-range diesel shared across several machine lines, and its most consistently reported issue is oil migrating past turbocharger seals into the exhaust/intake path as hours climb, showing as visible smoke or oil consumption. Ring and piston wear producing elevated blow-by is the other recurring complaint on higher-hour, poorly maintained examples. A neglected oil change interval has also been linked to premature main bearing wear that can allow a rod or piston to contact the cylinder wall — a low-oil-pressure warning should never be run through. Have your dealer verify oil pressure and blow-by levels on any engine showing smoke or oil loss.
What electrical or monitor-panel issues come up on Komatsu -1 series graders like this one?
The recurring complaint in this generation's monitor/gauge cluster is a central warning lamp or buzzer that won't clear, either staying lit continuously or flickering intermittently, which usually traces to a wiring or connector fault in the monitor circuit rather than the sensor it's paired with. Individual gauge senders (oil pressure, coolant temperature, hydraulic oil temperature) are also reported as failure points that mimic a real fault. Because a stuck or false warning can mask a genuine oil-pressure or brake-pressure fault, have your dealer verify the actual sensor reading with a separate gauge before dismissing a warning lamp as nuisance wiring.
Do the articulation joint and steering pins need special attention on this grader?
Yes — articulation hinge pins, bushings, and the steering/drawbar ball joints are named as routine wear points across this grader family, and owners who fall behind on the grease interval see accelerated bushing wear and eventually detectable play at the hinge. Regular greasing at the recommended interval, especially in dusty or high-cycle applications, is what keeps these joints within service life; once clearance opens up, replacement rather than adjustment is the fix.
What should a buyer check when looking at a used GD510R-1 (S/N 15001-UP)?
Cycle the blade lift, tilt, and circle-turn functions through full range and watch for lag, drift, or noise that points to worn cylinder seals or a tired circle drive. Check circle rail and drawbar ball play by hand — looseness there is a wear item, not a quick fix. Inspect moldboard cutting edges and end bits for remaining life and even wear, and check articulation and steering linkage for slop. Start the engine cold and watch for exhaust smoke or slow oil pressure buildup, both flags for the S6D95L-1's known wear patterns at higher hours. Confirm all monitor-panel warning lamps clear normally after start and that none stay illuminated. Have your dealer verify hydraulic pressures, engine compression/blow-by, and circle-drive condition before finalizing a purchase.
Is the transmission or drivetrain on this grader known for any particular issues?
Reports specific to this grader's powershift transmission are thin in owner/operator discussion, which itself is consistent with a mechanically conventional, well-proven drivetrain rather than a chronic problem area. The general guidance from operators of this machine class is standard powershift care: fluid and filter changes on schedule and prompt attention to any shift harshness or slipping, since transmission wear tends to announce itself gradually through shift quality before a hard failure.
