SA6D155-4A Fuel System Parts lookup notes

Use this hub when the repair has already been narrowed to fuel system parts. Confirm each part against the engine serial range, parts-book callout, quantity, and option notes before ordering.

Parts-book verification before ordering

Komatsu engine parts often change by engine arrangement, serial range, diagram callout, and option note. 19PARTS uses engine-model organization to help you move from a broad Komatsu part number search into a tighter reference path, but final fitment should always be confirmed against your engine serial number and parts book.

Our Keep Ops Moving approach is simple: give buyers cleaner lookup paths, clear part-number references, and practical cross-navigation so rebuild shops, fleet teams, mechanics, and equipment owners can identify the right components faster.
