Komatsu BR200J-1(S/N 1201-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu BR200J-1(S/N 1201-UP) is a self-propelled, crawler-mounted mobile jaw crusher for on-site demolition and construction-debris recycling, built for the Japan market from the mid-1990s. It runs the Komatsu S6D95L-1, a mechanically governed, direct-injection diesel inline-six of about 5.88 L displacement (bore x stroke 102 x 120mm) with no electronic engine control. Exact power output for this crusher application is not published in factory literature, though the same base engine block powered a wide range of Komatsu excavators, loaders, and dozers of the period. Operating weight runs around 19.5t (43,000 lb), with a single-toggle jaw box opening of about 700 x 500mm (27.5 x 20in), a vibrating grizzly feeder, a standard magnetic separator for pulling rebar out of the crushed product, and a roughly 620mm discharge conveyor, all built onto the machine rather than offered as swap-in work tools. Transport dimensions run about 6.0-6.1m long, 2.5-2.8m wide, and 2.95-3.0m tall depending on source and configuration; travel speed is about 3.0 km/h with roughly 30-degree gradeability. Komatsu's self-propelled crusher line started with the smaller BR60 in 1992 and added the higher-throughput BR200 as a second model in 1993; this J-1 designation is one of several factory configurations sharing the BR200 chassis and shop-manual family, alongside the base BR200-1, the BR200S-1, the BR200R-1, a later Korea-market BR200J-1A, and a North America-market BR200T-1.
Within the family, the core crusher chassis, engine, and hydraulic drive carried over largely unchanged; differences were mostly in feeder and conveyor arrangement and in market-specific electronics. The later T-1 generation added an LCD monitor and control panel that this earlier J-1 does not have, running instead on analog gauges and warning lamps. Komatsu developed this line to meet demand created by Japan's 1991 construction-recycling law, which pushed contractors toward crushing concrete on-site rather than hauling it to a fixed plant; in Japan the lineup became known under a 'Gara-Pagos' nickname, and it grew over the following years into larger, fully hydraulic JG-series crushers such as the BR350JG-1 and BR380JG-3. In the used and parts market today, the BR200J-1 is a low-volume, Japan-market machine with limited outside distribution. Engine and common hydraulic components are easy to source because the S6D95L-1 and its pumps were shared across mainstream Komatsu equipment, but crusher-specific wear parts such as the jaw plates, toggle plate, and pitman bushings need to be sourced through a dealer or crusher-parts specialist rather than found off the shelf.

Servicing the BR200J-1(S/N 1201-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Sample S6D95L-1 engine oil at every change and watch for coolant or oil cross-contamination; head gasket seepage on this engine shows first as white or blue exhaust smoke or mixed fluids as it ages. Track hydraulic oil condition closely: the same circuit drives travel, the jaw crusher, and the discharge conveyor, and lugging under a heavy feed with no automatic load management accelerates pump and driveline wear. Log crusher-protection pressure-switch trips; frequent trips flag oversized feed or a jaw liner nearing its wear limit before a shutdown.
Corrective & Common Repairs
The toggle plate is a sacrificial wear part by design. A rhythmic knock during operation usually means a worn toggle seat, and uneven jaw-plate wear or extra pitman stress often traces to toggle misalignment or low tensioning pressure. Fixed and swing jaw liners are routine wear-replacement items in the 700 x 500mm chamber. Check the magnetic separator belt and discharge conveyor scrapers and idlers after any tramp-metal jam, and verify the hydraulic crusher-protection relief valve actually trips before relying on it to protect the pitman and bearings.
Overhaul & Rebuild Points
Pitman bushings and the crushing-chamber frame are the core structural items to inspect at overhaul. Old weld repairs or cracks around the jaw box usually point to a past tramp-metal strike. Because this generation runs no ECM, the S6D95L-1's mechanical injection pump and injectors should be bench-checked and recalibrated at major service rather than diagnosed electronically. Undercarriage wear on this crawler-mounted plant tracks running hours, not travel hours, since crushing vibration fatigues idlers, rollers, and the track adjuster spring even on a machine that repositions rarely.
Seasonal & Environment Servicing
Concrete and demolition dust load the air cleaner and radiator fast on an active site. Watch the air-restriction lamp and service both more often than a normal interval calls for. In cold weather, the S6D95L-1's glow plugs need to be in good condition; hard starting usually traces to a weak battery or tired glow plugs, not internal engine wear. Wash accumulated fines out of the crawler undercarriage and around the crushing-chamber frame regularly. Packed dust holds moisture against seals and accelerates corrosion on this ground-level, self-propelled chassis.

BR200J-1(S/N 1201-UP) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Engine oil pressure (warning lamp/buzzer) | Engine lubrication pressure has dropped below the safe minimum; the oil pressure switch opens and trips the lamp and buzzer. | Low oil level, clogged oil filter or strainer, worn oil pump, worn bearings, or a faulty pressure switch/wiring. | Stop the engine at once, check oil level and filter condition, inspect the pressure switch and wiring before restarting. |
| Coolant temperature (warning lamp/gauge) | Engine coolant temperature has risen above normal operating range. | Low coolant level, blocked radiator core or fan guard, slipping or broken fan belt, failed thermostat, or a faulty temperature sender. | Idle the engine to cool down, check coolant level and radiator fins, inspect fan belt tension and thermostat operation. |
| Charge (warning lamp) | Alternator is not charging the battery circuit. | Loose or broken alternator/fan belt, failed alternator, or a wiring/connector fault. | Check belt tension and condition, test alternator output, inspect wiring and connectors. |
| Air cleaner restriction (warning lamp) | Air filter element is clogged, restricting intake airflow to the engine. | Dust-loaded filter element or saturated pre-cleaner, common in a crushing/demolition dust environment. | Check the restriction indicator and service or replace the air filter element as needed. |
| Hydraulic oil temperature (warning lamp/gauge) | Hydraulic tank oil temperature has exceeded normal operating range. | Low hydraulic oil level, clogged oil cooler fins, or sustained heavy-duty operation in high ambient heat. | Idle to allow cooling, check oil level, clean cooler fins, inspect cooler fan operation. |
| Crusher/feeder overload (hydraulic pressure-switch trip) | A pressure switch in the crusher control circuit senses feeder or conveyor hydraulic pressure above its set point and trips the relief valve, stopping the feeder/conveyor to protect the crusher. | Oversized or uncrushable (tramp) material jammed in the jaw, feeder overfeeding the crusher, or worn jaw liners increasing crushing load. | Stop the feeder, clear the jam from the crusher throat, verify relief valve setting before resuming feed. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
BR200J-1(S/N 1201-UP) attachments & work tools
Jaw crushing chamber / wear plates
Single-toggle jaw box measuring roughly 700 x 500 mm (27.5 x 20 in), rated for feed lumps up to about 600 mm (24 in) on the largest dimension per the factory data sheet for this serial range. Fixed and swing jaw plates are high-wear cast liners replaced as a maintenance item, not a customer-selectable work-tool option.
Vibrating grizzly feeder
A vibrating grizzly feeder is built into the hopper ahead of the jaw box to screen out fines before crushing. It ships as part of the base machine rather than as a separate add-on kit.
Magnetic separator
A magnetic separator for pulling rebar and wire out of the crushed product is standard on the base machine, mounted over the discharge conveyor rather than sold as a bolt-on accessory.
Discharge / side-unload conveyor
Standard lateral-unload discharge conveyor is about 620 mm (24 in) wide and built onto the chassis. Dealers serving this class also offered a separate roughly 13 m hydraulic belt conveyor to extend stockpiling reach beyond the machine's own short discharge run.
Undercarriage / mounting system
Crusher box, feeder, magnet, and conveyor are permanently fixed to a self-propelled crawler chassis; there is no quick-coupler or interchangeable work-tool mount as on an excavator. Travel speed is about 3.0 km/h with roughly 30-degree gradeability.
Power / hydraulic arrangement
Feeder, conveyor, and magnet all run off the machine's own engine-driven hydraulic system - an S6D95L-family diesel for this serial range - so no external power pack or hydraulic hook-up is needed to run the standard work equipment.
Factory transport configuration
Compact feed-and-discharge-on-the-same-side layout at about 19.5 t operating weight and roughly 6.0-6.1 m long keeps the machine within permit-free road transport limits on a standard low-bed trailer. Reported transport width/height vary slightly by spec sheet (about 2.5-2.8 m wide, 2.95-3.0 m tall) - varies by configuration/source.

BR200J-1(S/N 1201-UP) serial number reference
The serial plate on this crusher carries the full model code (BR200J-1) followed by the serial number. Documentation for this range consistently lists a plain numeric serial (1201-UP) with no alphanumeric prefix ahead of the digits, so the number simply runs sequentially from 1201 upward within the JPN-market build. The letter/number suffix in the model code itself (J-1 vs J-1A for Korea, R-1, S-1, T-1) is what marks the market/configuration variant, not a prefix within the serial string. Exact plate placement on the machine is not documented in available factory literature for this model; check the main frame or control box area first, and confirm against the unit's own plate or your dealer's records.
| Prefix | Identifies | Notes |
|---|---|---|
| 1201-UP | BR200J-1 (JPN) self-propelled mobile debris/jaw crusher, Japan-market production run | Sole documented serial run for this designation; no sub-range split found within 1201-and-up. Mounts the S6D95L-1 series diesel (S6D95L-1JJ cited in parts/engine cross-reference). Factory shop manual for this range issued February 1995 in Japan; separate spec listings place the model in the 1996-1997 sales window, so treat exact build year as approximate and confirm against the individual unit's plate. |
Frequently asked questions
What engine does the Komatsu BR200J-1(S/N 1201-UP) use?
The Komatsu S6D95L-1, a mechanically governed, direct-injection diesel inline-six of about 5.88 L displacement, glow-plug assisted for cold starts, with no electronic engine control. Crusher-specific power output is not published in factory literature; the same base engine also powered Komatsu excavators, loaders, and dozers of the period.
What is the operating weight of the BR200J-1(S/N 1201-UP)?
About 19.5 tonnes (43,000 lb) in factory configuration, with minor variation depending on the exact feeder, magnet, and conveyor fitment. Transport dimensions run roughly 6.0-6.1m long by 2.5-2.8m wide, within permit-free low-bed trailer limits.
What replaced the Komatsu BR200J-1?
Komatsu did not carry the exact J-1 model code forward. Later production in the same family moved to updated variants such as the North America-market T-1 generation, which added an LCD monitor and control panel this J-1 lacks. Komatsu's broader self-propelled crusher lineup, which began with this same BR60/BR200 generation, went on to larger, fully hydraulic JG-series crushers as the platform matured.
What BR200J-1(S/N 1201-UP) owners discuss
What's known about how the S6D95L-1 engine and hydraulic system behave together on this machine?
The S6D95L-1 is a mechanically governed, direct-injection diesel with no electronic engine control. It drives the hydraulic pumps that power track travel, the jaw crusher, and the discharge conveyor. Throttle response is direct and predictable, but there is no automatic load management, so the operator has to modulate feed rate by hand to keep the jaw from bogging under a heavy load. Sustained lugging under overload is the main driver of early wear on the hydraulic pump and drive line, a trait common to mechanically governed diesels of this era and class, not unique to this unit.
What undercarriage wear patterns should an owner expect on a machine like this?
This is a track-mounted crusher that repositions occasionally rather than a dozer that travels all day, so undercarriage hours build slowly compared with the hour meter. But the crushing action puts continuous vibration into the frame and tracks while the plant runs, and that vibration drives fretting wear on idlers, rollers, and the track adjuster spring even on a machine with low recorded travel. Track tension needs checking on a running-hours basis, not just a travel-hours basis. This reflects general tracked-crawler undercarriage behavior for this class of stationary or semi-mobile plant; detailed wear data specific to this exact model is not published.
Are there known quirks with the S6D95L-1 engine across this series worth knowing?
It is glow-plug assisted for cold starts; hard starting in cold weather usually traces to a weak battery or tired glow plugs rather than internal engine trouble. As the engine ages, watch for head gasket leakage: white or blue exhaust smoke, or oil and coolant cross-contamination, are the tell. On the plus side, this engine block was used across a wide range of Komatsu excavators, loaders, dozers, and forklifts from the same period, so engine parts and rebuild expertise are easier to find than the crusher-specific parts are.
What electrical or sensor issues come up on machines of this vintage?
Electrics on this generation are simple: analog gauges, mechanical sender units, a conventional starter and alternator. Age-related issues are the usual ones: corroded connectors and grounds giving false gauge readings, alternator diode failure causing charging problems, and worn starter contacts. The one sensor worth specific attention is the hydraulic crusher-protection pressure switch, which works with a relief valve to protect the jaw and pitman when the crusher hits tramp metal or an uncrushable object. If that switch or valve sticks or reads incorrectly, the protection system may not trip when it should. Have your dealer verify the crusher-protection circuit functions correctly before relying on it.
What about the toggle plate and jaw mechanism? What wear or failure patterns are typical?
The toggle plate is a sacrificial part by design, meant to fracture under a calibrated overload rather than let shock load reach the frame, pitman, and bearings. A rhythmic knocking during operation usually means a worn toggle seat. Uneven wear on the jaw plates or extra stress on the pitman often traces back to a toggle that is out of alignment or a tension spring or hydraulic tensioning pressure that is too low. Because the toggle and tension system store energy under load, have your dealer verify tension spring condition and hydraulic tensioning pressure before adjusting or servicing this area.
What should a buyer check before purchasing a used BR200J-1 (S/N 1201-UP)?
Run the engine and watch exhaust smoke color and check for any oil or coolant cross-contamination as a first read on the S6D95L-1's internal condition; a compression check confirms it. Inspect the jaw plates, toggle plate, and pitman bushings for wear or play, and check the crushing-chamber frame for cracks or old weld repairs, which point to past tramp-metal strikes. Confirm the hydraulic crusher-protection system actually trips and resets. Check track and roller wear against actual operating hours, since vibration wear can outpace travel wear on this type of plant. Ask for maintenance records: because this is a Japan-market machine with limited distribution elsewhere, an import history with service records is worth more here than on a common excavator, and parts lead time for crusher-specific wear items should be confirmed with a dealer before buying.
Is parts support a common concern for owners of this model?
Yes, more so than for Komatsu's mainstream machines. The BR200J-1 was a Japan-market mobile crusher from the mid-1990s with limited distribution outside Japan, so it does not have the same secondary parts market as a comparable excavator. Engine and common hydraulic components are easier to source because the S6D95L-1 and its pumps were shared across other Komatsu equipment of the period. Crusher-specific wear items such as jaw plates, the toggle plate, and pitman bushings are the parts owners report needing to plan ahead for, sourcing through a dealer or crusher-parts specialist rather than finding off the shelf.
