How This D85ESS-2A Parts Catalogue Is Organised

Every section follows a consistent exploded-view format: a detailed illustration with numbered callouts, followed by a table listing each item number, the Komatsu part number, the part name, the quantity required, and the serial number range where that part applies. This structure makes it straightforward to trace a component from the drawing to its exact part number, even when multiple variants or superseded numbers exist. The catalogue covers the D85ESS-2A and D85E-SS-2A-E from serial 3034-UP, with separate sections for machines fitted with the S6D125E-2H-6 engine. Whether you are rebuilding a cylinder head, replacing undercarriage components, or sourcing a single hydraulic fitting, the relevant diagram and part table are together in one place.

Practical Uses for the D85ESS-2A Parts Catalogue

This PDF is built for anyone who needs to identify and order parts for a D85ESS-2A or D85E-SS-2A-E dozer. It supports engine overhauls by showing the complete cylinder head, piston, crankshaft, camshaft, and valve train assemblies with every associated gasket, seal, bolt, and insert. Powertrain work is covered through the torque converter, transmission, clutch and brake, final drive, and steering sections. Undercarriage maintenance is backed by exploded views of the front idler, track rollers, carrier rollers, track shoe, and track frame. Hydraulic system repair is supported by detailed diagrams of the hydraulic tank, control valve, pump, lift cylinder lines, tilt lines, and ripper piping. The cab, ROPS, engine hood, fenders, operator seat, and air conditioner sections round out the catalogue, making it a complete reference for the entire machine, not just the engine.

Why a Parts Catalogue Matters for Your D85ESS-2A

Ordering the wrong part for a dozer is expensive and time-consuming. This catalogue removes the guesswork by tying every part number to a specific illustration and serial number range. You can confirm at a glance that the part you need matches your machine’s configuration, whether it is an early 3034 serial or a later 60721-UP unit. The inclusion of oversize and undersize options for valve inserts, main metal bearings, and thrust metals is especially valuable when rebuilding an engine, as it lets you order the exact repair size in one step. For workshops maintaining a fleet of D85ESS-2A dozers, having this catalogue on hand reduces downtime and eliminates the back-and-forth of trying to identify a part from a worn original.
