Yanmar 6EY26 Parts Catalog – Hydraulic Oil Governor Spec Marine Diesel Engine PDF

Description

Yanmar 6EY26 Parts Catalog — Hydraulic Oil Governor Spec

This is the complete first-edition parts catalog for the Yanmar 6EY26 main engine in Hydraulic Oil Governor specification. Issued as Parts Catalog No. 000Y00H3470 in June 2004 and published in this revision in 2008, the document runs to 111 pages and breaks the engine down into 96 illustrated assembly groups. Every group combines an exploded illustration with a corresponding parts table listing reference numbers, part numbers, descriptions, and required quantities per engine model.

Because this catalog is dedicated to the 6EY26, the part numbers, quantity columns, and assembly breakdowns apply directly to that engine rather than being spread across a broad model family. That specificity is what makes it useful for anyone maintaining, rebuilding, or sourcing components for a 6EY26.

Within each group the parts list is structured by reference number, level indicator (main assembly, sub-component, sub-sub-component), part number, description, and quantity per engine model. Interchangeability marks (N, Q, R, S, W, Z, F, K) identify which part numbers can replace which, and effective machine numbers are noted where a design change occurred.

What This Catalog Enables

This is a working parts identification document, not a repair guide. It gives you the exploded assembly views and the exact part numbers needed to identify and order components for the 6EY26. If you are rebuilding a cylinder head, replacing a turbocharger, tracing a fuel line, or checking which piston ring set matches your engine, the relevant figure and parts table are here.

Because the catalog covers the engine in its Hydraulic Oil Governor specification, it also documents the governor, speed control linkage, fuel cut mechanism, and the HPR5000 turbocharger as separate spare-parts groups — useful when the engine is being maintained as a complete package rather than as an isolated long block.

Why It Matters

Ordering the wrong part number for a large marine diesel is expensive in both time and money. This catalog reduces that risk by tying every component to a specific figure, reference number, and quantity. The interchangeability marks tell you whether a newer part number supersedes an older one, and the effective machine number columns show when a change was introduced. That is the kind of detail that keeps a rebuild on schedule.
