Volvo EC25 Excavator Parts Catalog Manual 2000 onwards (P/N 64C4410005)

• Machine and build coverage: Volvo EC25 Type 281 excavator, identified as basic machine 281.10151, with machine- and engine-number applicability notes throughout the catalog.
• Engine parts identification: Separate coverage for the S3L2-63ES and S3L2-W263ES engines, including internal components, repair kits, fuel injection, lubrication, intake, exhaust, and cooling assemblies.
• Electrical and power-transmission systems: Battery, charging and starting equipment, anti-start keypad, cab and canopy harness layouts, travel and swing motors, balancing valves, swivel joint, and slewing ring.
• Hydraulic and work-equipment breakdowns: Eight- and nine-spool control valves, pumps, accumulators, electrovalves, attachment circuits, control-pattern equipment, quick couplers, and serial-specific cylinders.
• Undercarriage, cab, and equipment variants: Steel and rubber crawler assemblies, track tensioners, rollers, cab and canopy parts, glazing, seating, heating, buckets, dipper arms, and market-adapted equipment.
• Factory document details: Publication No. VOE 64C4410005, Catalog ID 10005, supplied as a 669-page PDF with English, French, German, and Spanish descriptions, more than 250 distinct numbered parts illustrations, a replaced-parts cross-reference, and a numerical part-number index.

This Volvo factory parts catalog is intended for identifying and ordering components for the EC25 Type 281. It is best suited to technicians, parts-counter staff, and experienced EC25 owners who can match the machine, engine, and manufacturing plates to the applicability notes before selecting repair parts.

Match the Correct EC25 Build

The catalog identifies the complete S3L2-63ES engine as VOE 11804244 and the S3L2-W263ES as VOE 11806067. Their sections break down the cylinder head, block, pistons, rocker shaft, timing gears, camshaft, connecting rods, oil pump, injection pump, injectors, fuel piping, radiator, water pump, and related hardware.

Several engine components change at specific engine numbers. The S3L2-63ES listings distinguish applications through engine no. 65746 from those beginning at 65747, while several S3L2-W263ES parts are identified from engine no. 70161. These distinctions affect items such as connecting rods, seals, fuel lines, belts, and mounting parts.

Machine serial divisions are equally important. Separate parts plates cover the dozer-blade, boom-offset, boom, dipper-arm, and bucket cylinders for S/N 15541-15702, 15704-15714, and 15717-15718 versus S/N 15539, 15540, 15703, 15715, and 15716. Ordering by the EC25 model name alone can therefore supply the wrong seals, piston hardware, or cylinder components, which may be damaged during attempted assembly or leak after the repair.

What Each Parts Plate Provides

Illustration callouts are linked to OEM part numbers, required quantities, kit relationships, and application notes. The parts-status columns identify components that are no longer stocked and numbers that have been superseded. Cross-references direct the reader to related assemblies, while Group 10 provides both the replacement history and a numerical lookup for part numbers used elsewhere in the catalog.

Representative drawings include cylinder-head and timing-gear breakdowns, front and rear electrical harness layouts, traveling hydraulic motor and balancing-valve views, eight- and nine-spool hydraulic control valves, steel and rubber track-tensioning assemblies, and serial-specific hydraulic cylinder exploded views. Electrical coverage also separates cab, canopy, and “without Puma” configurations.

Market and Equipment Variants

The market-equipment tables identify 300 mm steel and rubber tracks, toothed buckets from 250 to 750 mm, 1000 and 1300 mm slope buckets, and 1200 and 1500 mm dipper arms. Other listed configurations include cab or canopy, fabric or vinyl suspension seats, pre-cleaner, work lights, battery cut-out, wind protection, standard or catalytic exhaust, mechanical attachment bracket, and radio equipment.

Hydraulic sections distinguish standard and USA control arrangements, the USA standard/ISO selector, mechanical and hydraulic tool holders, snap-action and Quickfit attachments, double-acting auxiliary hydraulics, and grab-jaw circuits.

Parts Catalog Scope

This publication is a parts-identification catalog, not a workshop repair manual. It does not provide removal sequences, overhaul procedures, diagnostic charts, torque tables, hydraulic pressure tests, or adjustment specifications. The electrical illustrations show harness routing and component relationships rather than diagnostic wiring schematics.

Volvo specifically states that the numbered illustrations must not be used as assembly or workshop instructions. Their callout order is not a repair sequence; treating it as one can damage seals or internal hydraulic components during reassembly.

The opening group legend names Track Brake as Group 5, but this PDF contains no standalone Group 5 page section. Brake kits, a brake piston, and a brake-disc kit are identified within the slewing gear motor breakdowns instead. Hydraulic and attachment repair work also involves stored pressure and unsupported structures, so the applicable Volvo workshop literature and proper support equipment are still required.
