2000 Komatsu PC75UU-2 Hydraulic Excavator Shop Manual (P/N SEBM001302)

Komatsu publication P/N SEBM001302 covers 2000 PC75UU-2 hydraulic excavators equipped with the 4D95L-1 engine, including cab and canopy configurations and serial numbers 5001 and up.

Bookmarks and diagram detail: Chapter and procedure bookmarks support navigation; text search is unavailable. Small wiring-diagram labels require enlargement for comfortable reading. The separate Main Menu link needs a companion file that is not included.

• Engine testing and repair: Compression testing, valve-clearance adjustment, fuel-injection timing checks, and engine and cylinder-head removal and installation procedures.

• Hydraulic diagnosis: Main and control-circuit pressure tests, PPC and EPC valve checks, internal cylinder leakage measurement, motor drain-leakage tests, and hydraulic bleeding.

• Component rebuilding: A10VD43 main pump, LMF40AB-2 swing motor with brake, center swivel joint, and three-spool control-valve disassembly and assembly.

• Undercarriage work: Track shoe tension adjustment, recoil spring assembly service, idler and roller replacement, and procedures for rubber shoes, steel shoes and roadliners.

• Electrical troubleshooting: Wiring diagrams, connector arrangement drawings, four-system controller diagnosis, potentiometer adjustment, and electrical input/output signal reset procedures.

• Workshop reference data: Hydraulic piping and circuit diagrams, general assembly drawings, standard tightening torque charts, fluid capacities, cylinder specifications and maintenance standards.

Written for service technicians carrying out workshop repairs with the specified test equipment and special tools.

Hydraulic and Mechanical Systems

The hydraulic testing section documents relief-valve settings, travel motor operational parameters and control-circuit pressure. Its cylinder-leakage checks help distinguish an internal cylinder fault from a control-valve fault when diagnosing hydraulic drift.

Main-pump repair covers internal inspection and assembly. Swing-motor procedures include shaft end-play adjustment, turning-torque measurement and valve-plate contact checks; the assembly notes warn that impact can damage and distort the valve plate's sliding surface.

The three-spool control valve has internal disassembly and assembly procedures, while the four-spool unit is covered for removal and installation. Hydraulic repair requires pressure release and secure support for raised work equipment.

Engine Service and Serial-Number Differences

Essential engine data includes compression pressure thresholds, valve clearance specifications, and fuel injection timing values. Removal and installation procedures cover the fuel injection pump, cylinder head, crankshaft seals, water pump, starter and alternator.

Separate procedures apply to serial numbers 5001–7927 and 7928 and up, including cylinder-head work and engine/main-pump removal. The instructions distinguish the earlier engine-stop motor cable from the later stop-solenoid linkage.

For further engine details, Komatsu refers readers to the separate 95 Series Engine Shop Manual. That engine manual is not included in this file; this excavator publication does not provide a full internal engine overhaul chapter.

Electrical Diagnostics and Controller Settings

Electrical circuit diagrams distinguish the 5001–5494 and 5495-and-up serial number groups. Connector pinouts, sensor resistance ranges, fuse ratings and standard value tables for electrical parts support circuit-level testing.

Troubleshooting charts separate E-mode electrical, H-mode hydraulic/mechanical and M-mode machine-monitor faults. The four-system controller sections cover interference prevention and height, depth and offset limits, with error-code and symptom-based diagnosis.

Input/output resets address controller, potentiometer and work-equipment changes; depth-display compensation resetting applies to serial numbers 5495 and up. The tool list specifies T-adapter kit 799-601-7100 for wiring-harness and sensor testing.

The cancel-switch precautions explain how operating that switch during a solenoid-circuit short can damage related diodes before the fuse opens. The troubleshooting section identifies the associated diodes for each affected solenoid.

Tracks, Frames and Work Equipment

Serial-specific sections distinguish track-roller procedures for machines numbered 5001–7927 and 7928 and up. PPC valve disassembly and assembly instructions use the same serial-number split.

Track frame assembly standards provide inspection and wear limits. Work-equipment procedures cover boom, arm, bucket and blade removal, cylinder disassembly and assembly, and pin, bushing and clearance checks.

Swing machinery has removal, disassembly and assembly procedures; swing-circle coverage addresses removal and installation.

Printable PDF and Included Revisions

Supplied as one printable, English-language 399-page PDF. The total includes the cover, two revision-list pages, 32 inserted pages covering special tools, swing-motor repair and main-pump repair, and 14 blank pages.
