Description

Komatsu D37EX-24 / D37PX-24 / D39EX-24 / D39PX-24 Bulldozer Shop Manual

This is the complete Komatsu Shop Manual SEN06586-03 covering the D37EX-24, D37PX-24, D39EX-24, and D39PX-24 bulldozers powered by the SAA4D95LE-7 diesel engine. It is the same type of in-shop reference used by service technicians to test, adjust, troubleshoot, disassemble, assemble, and maintain these machines. Whether you are diagnosing a hydraulic fault, setting HST pressures, overhauling a final drive, or looking up a maintenance standard, the information is organised by system and cross-referenced so you can move from symptom to specification quickly.

Across roughly two thousand pages the manual builds a complete picture of these four dozer variants: the SAA4D95LE-7 engine and its aftertreatment hardware, the HST drivetrain that these machines rely on, the work equipment hydraulics, the electrical architecture, and every service value a technician needs to judge wear or set a component back to specification. Because the same document spans all four models and both undercarriage families, it is unusually efficient — one reference covers a fleet of closely related machines rather than forcing you to track down a separate book for each.

What This Manual Lets You Do

With SEN06586-03 on hand, you can perform real diagnostic and repair work on the D37EX-24, D37PX-24, D39EX-24, and D39PX-24 rather than guessing. The troubleshooting chapters walk through failure codes, E-mode electrical faults, H-mode hydraulic and mechanical faults, and S-mode engine faults, each tied to a test or measurement. The testing and adjusting chapters give you the tools, the procedure, and the criteria so you can decide whether a pump, valve, motor, or sensor is within limits or needs attention. Disassembly and assembly instructions include tightening torques, coating materials, and special tool references, while the maintenance standard tables provide the wear limits that determine whether a component can be reused. Having the exact procedures and specifications in front of you reduces the risk of damaged parts, repeat failures, and expensive downtime.

Additional Reference Value

Beyond the repair work itself, the manual is a useful specification reference. The standard value tables give engine and machine values for each of the four models, the weight table helps with lifting and transport planning, and the table of fuel, coolant, and lubricants identifies what should go into each reservoir. The connector and fuse location tables, together with the circuit diagrams in section 90, make tracing electrical faults far more practical than working blind. For anyone maintaining a mixed fleet of these dozers, the cross-model structure means you can move between machines without switching documents.

Instant PDF Delivery

The manual is delivered as a downloadable PDF the moment your order is complete — there is no shipping and no waiting for a physical book. It opens on a laptop, tablet, or phone, and any page or section can be printed for use in the workshop. Because it is a digital file, you can keep a copy on the service computer and another in the cab without carrying a paper binder around.
