1996– Volvo EC15B Type 272 XR Excavator Parts Catalog (P/N VOE 6444410017)

Volvo Construction Equipment's parts catalog for the 1996–Present EC15B Type 272 XR covers the L3E2-64ESA and NAFTA L3E-W264ESA engine configurations. Publication VOE 6444410017 pairs component illustrations with factory part numbers, quantities, and fitment notes.

Text search and drawing detail: Introductory text, parts tables, and indexes support PDF text search; drawing labels do not. The three embedded bookmarks lead to the cover only. Small wiring labels require zooming.

• Engine components: Cylinder heads, pistons, camshafts, injection pumps, and fuel-system parts, with separate listings for the two engine configurations.

• Power transmission: Travel motors without brakes, slewing gear motors, swivel joints, and slewing rings, with exploded component views and repair kit references.

• Hydraulic components: Hydraulic pumps, eight-spool control valves, accumulators, electrovalves, and attachment circuits, including NAFTA control-layout differences.

• Undercarriage: Lower frames, track tensioning mechanisms, sprockets, rollers, and rubber tracks, organized by applicable machine serial numbers.

• Electrical and cab equipment: Starter motors, alternators, coded keypads, harness drawings, cab heating, and separate cab and canopy equipment listings.

• Digging equipment: Dozer blades, boom and dipper-arm assemblies, telescopic arms, hydraulic cylinders, and conventional or Quickfit buckets.

Suited to mechanics and owners who can match exploded-view callouts and part numbers to the machine's identification plates.

Serial Numbers and Parts Selection

Undercarriage changes: Parts lists distinguish 272.10151–272.11461 from 272.11462 onward for the travel motors, lower frames, tensioners, sprockets, tracks, and rollers. Matching that break before ordering helps avoid selecting a different undercarriage version for the repair.

Cylinder exceptions: The dozer-blade, boom-offset, boom, dipper-arm, and bucket cylinders have early listings for 272.10151–272.10178, additionally marked S/N 10180. Later listings start at 272.10181 and additionally identify S/N 10179.

Cab and controls: Cab-specific sections use CAB 20/01/001 onward. Instrument-panel supports, spacers, and mounting screws change at 272.11327/272.11328.

Engine and Cooling System Reference

Separate cylinder-head and piston part numbers distinguish the two diesel versions. The catalog also separates their injection pipes, injection-pump controls, and intake manifolds.

The “Injection pump” drawing is paired with selectable shim thicknesses; piston and bearing tables identify standard and alternative sizes. Cooling-system drawings identify radiator installation hardware, hose connections, water-pump components, the thermostat, and expansion tank.

Hydraulic Connections and Electrical Layouts

The “Control valve: 8 spools” illustrations break the valve assembly into elements, pressure compensators, and seal kits. “Swivel joint” links individual seals to their kit ordering reference.

Hydraulic layouts cover the auxiliary, double-acting, and grab-jaw circuits. Standard and NAFTA attachment-control drawings distinguish the US Std/ISO selector arrangement.

The “Electrical system / without Puma” diagram identifies harness connections and component codes; separate sheets show cab and canopy wiring locations.

Parts Identification and Catalog Limits

Exploded views support parts identification and repair planning. Volvo expressly excludes using these illustrations as assembly or workshop instructions. This catalog does not provide overhaul sequences, torque tables, pressure-testing procedures, or troubleshooting charts.

The numerical index links part numbers to their group, section, and page. Superseded-part tables and kit-ordering notes help distinguish individual items from replacements supplied as larger assemblies.

Use the appropriate service manuals and professional training before handling heavy equipment maintenance, especially raised attachments and pressurized hydraulic components.

PDF Contents and Included Reference Pages

One printable, 447-page PDF with English, French, German, and Spanish descriptions. The total already includes 2 cover/title pages, 13 Volvo divider pages, the 2-page replaced-parts section, and the 11-page numerical index.
