Description

Komatsu D155AX-5 Shop Manual – SEBM034803

The Komatsu D155AX-5 Shop Manual SEBM034803 is the complete service reference for the D155AX-5 crawler dozer, covering serial number 76001 and up. It gives mechanics, fleet maintenance teams and dozer owners direct access to the same procedural structure Komatsu field technicians work from – general information, structure and function, testing and adjusting, disassembly and assembly, and maintenance standards for every major system on the machine.

This Komatsu D155AX-5 service manual is delivered as an instant-download PDF and applies to machines running the SA6D140E-3 engine (for engine-specific overhaul data, the manual points to the separate 140-3 Series Engine Shop Manual). Everything else on the machine – the torque converter, Torqflow transmission, HSS case, final drives, steering, brakes, blade and ripper hydraulics, undercarriage and operator station – is covered here in full workshop depth.

What this D155AX-5 shop manual covers

Unlike a basic owner’s booklet, the SEBM034803 manual is organised as a full shop-floor reference. It walks through removal, installation, disassembly, assembly, inspection and adjustment for every serviceable assembly on the dozer, with torque values, clearances, service limits and special tool part numbers published alongside each procedure. The chapter layout follows Komatsu’s standard numbering convention, so any procedure referenced in the field can be located quickly by page group.

Chapters Covered

The Komatsu D155AX-5 shop manual SEBM034803 is divided into the following major sections:

• 01 – General: safety, standard torque values, unit conversion, general precautions, blind plug and sealant reference
• 10 – Structure, Function and Maintenance Standard: system layouts, component descriptions, operation principles and maintenance standard values
• 20 – Testing and Adjusting: measuring procedures, test ports, adjustment values, ECMV oil pressure, track tension, belt tension, bleeding procedures
• 30 – Disassembly and Assembly: full removal, installation, disassembly and assembly procedures for every major unit
• 40 – Maintenance Standard: wear limits, service limits, and inspection criteria
• 90 – Others: supplementary reference information

Within the Disassembly and Assembly chapter, the manual provides dedicated procedures for the complete range of machine systems, including:

• Starting motor, alternator, water pump, turbocharger
• Engine oil cooler core, fuel supply pump, fuel injector, nozzle tip
• Engine front seal, engine rear seal, cylinder head, thermostat
• Air conditioner compressor, air conditioner condenser
• Fuel tank, radiator, fan drive, fan motor, hydraulic cooler
• Engine, damper assembly, damper cover, flywheel
• Power train unit, PTO, torque converter, Torqflow transmission
• HSS case, hydraulic pump, HSS motor
• Power train main relief valve, HSS and PPC charge valve
• Transmission control valve, brake valve
• Final drive, track frame, idler, recoil spring
• Track roller, bogie, carrier roller, track shoe, one link, master link
• Pivot shaft, equalizer bar, segment teeth
• Hydraulic tank, main control valve, HSS oil cooler bypass valve
• Blade PPC valve, ripper PPC valve
• Blade lift, blade tilt, ripper lift and ripper tilt cylinders
• Blade assembly, multi-shank ripper, ROPS guard
• Operator cab, hood, floor frame, dashboard, monitor, HSS controller

Every one of those assemblies is broken down with step-by-step removal, disassembly, inspection, assembly and installation guidance, accompanied by illustration pages and torque callouts. If you are doing a clutch pack rebuild inside the Torqflow transmission, refreshing a final drive floating seal, setting bevel gear backlash or simply swapping a turbocharger, the sequence is laid out the same way a Komatsu technician would carry it out.

Why the SEBM034803 manual matters in the workshop

The D155AX-5 is a large, heavy dozer, and mistakes during disassembly or assembly are expensive. The torque figures alone – such as the final drive mounting bolts at 1323.0 ± 147.1 Nm, the bogie mounting bolts at 1863.3 – 2353.7 Nm, and the cylinder head bolts which are tightened in staged steps and then angle-tightened by 90°+30° – are not values you can guess at. The same is true of clearance limits like the standard idler guide clearance of 0.5 – 1.0 mm, or the bevel gear backlash range of 0.25 – 0.33 mm in the HSS case. Each of those values is published in this Komatsu D155AX-5 shop manual, and getting them right is what separates a reliable repair from a comeback.

The manual also documents the special Komatsu tooling (with part numbers) required for press-fit operations, floating seal installation, bevel pinion nut removal, track press work and the recoil spring decompression procedure – so you know in advance what you need on the bench.
