This Komatsu BX50 parts manual is organized by system, with each section providing exploded-view illustrations and detailed parts lists. Every illustration is keyed to a parts table that includes the item number, part number, description, quantity required, and serial number applicability. This structure allows you to visually identify a component, locate its part number, and confirm it matches your specific truck configuration before ordering.

What This Parts Manual Enables

With this BX50 series parts manual, you can confidently identify and order replacement parts for every major system on your forklift. The engine sections alone cover complete assemblies, cylinder blocks, cylinder heads, pistons, crankshafts, camshafts, carburetors, fuel pumps, governors, water pumps, ignition systems, alternators, starter motors, and gasket kits for both the K21 and K25 gasoline/dual fuel engines as well as the 4D98E diesel engine. Whether you need a single gasket or a complete short block, the exploded diagrams and part number tables give you the exact information required.

The transmission and drivetrain chapters provide complete breakdowns for the torque converter, Torqflow transmission (including input, idler, valve assembly, and external case components), drive axle, differential gear, and steer axle. Brake system coverage spans service brakes for all model sizes, master cylinder and piping configurations, power brake boosters, and parking brake assemblies. The hydraulic system chapters detail the hydraulic pump, control valve, tilt cylinders, power steering cylinder, and all associated piping and hoses.

Mast coverage is extensive, covering E50-MD dual masts, E50-MS 2-stage masts, E50-MT 3-stage masts, E65-MS and E65-MT masts, 45D-MQ and 55D-MQ 4-stage quad masts, and KU 2-stage and 3-stage full free view masts. Each mast section includes safety decals, lift cylinders, uprights, carriages, hoist chains, load backrests, mounting parts, lowering control valves, and internal hose reeving configurations. Options such as sideshifters, fork positioners, and integral sideshifters are also covered.

Additional chapters cover the electrical system with engine and dashboard harnesses for gasoline, dual fuel, and diesel models, the meter panel and combination switch, headlights and combination lights, the frame and chassis, counterweights, operator seat options, overhead guard components, and the full range of name plates and decals. The numerical index at the end allows you to look up any part number and find the exact page where it appears.

Engine Coverage in Detail

The engine chapter is the largest section of this parts manual, reflecting the complexity of the powertrain across the BX50 range. For the K21 and K25 gasoline and dual fuel engines, the manual covers complete engine assemblies, transmission-to-engine mounting parts, mounting hardware, bare and short block assemblies, cylinder blocks and oil pans, cylinder heads and rocker covers, crankcase ventilation, pistons, crankshafts and flywheels, camshafts and valve mechanisms, front covers and fittings, intake and exhaust manifolds, lubricating systems, carburetors (separate sections for K21 and K25), fuel strainers and hoses, air cleaners, fuel pumps, governors, vaporizers, LPG filters and piping, water pumps, cooling fans, thermostats, ignition systems, distributors, vacuum piping, alternators, starter motors, relays, and complete gasket kits.

For the 4D98E diesel engine, the manual provides similar depth: complete engine assembly, mounting parts, air cleaner, cylinder block, gear housing, flywheel housing and oil pan, cylinder head and head cover, intake and exhaust manifolds, camshaft and driving gear, crankshaft and piston, lubricating oil system, water cooling system, fuel injection pump, fuel injection nozzle and piping, fuel filter, starting motor, alternator, and gasket set. This level of detail ensures that no matter which engine variant your BX50 truck uses, you have the exact parts information required.

Why Accurate Parts Identification Matters

Ordering the wrong part for a forklift costs time and money. A part that looks similar may have a different specification, a different mounting pattern, or may be designed for a different serial number range. This Komatsu BX50 parts manual eliminates that guesswork by providing the exact part number, the quantity required, and the serial number range for every component. The exploded diagrams show how parts fit together, making it easy to identify a component even if you do not know its name. For fleet managers and technicians maintaining multiple BX50 series trucks, this manual is an essential reference that covers every model in the series with a single document.

The manual covers non-EPA gasoline and dual fuel models (FG20T-16, FG20HT-16, FG25T-16, FG25HT-16, FG30HT-16, FG35AHT-16) as well as EPA Tier 3 diesel models (FD20T-16, FD25T-16, FD30HT-16, FD35AT-16). Engine coverage includes the K21 and K25 engines used in gasoline and dual fuel models, and the 4D98E diesel engine. This breadth of coverage means you can use the same manual for the entire BX50 fleet, regardless of fuel type or capacity.
