Part of the Hitachi Parts Manuals.
All 336 pages of this Hitachi EX27U parts catalog PDF (OEM #P1AR-1-1) focus on one thing: giving you the exact breakdown of every assembly on your excavator. You get clear exploded views, complete part numbers, and precise component identification for the entire machine. Open to detailed diagrams covering the hydraulic pump device, canopy assemblies, and undercarriage track frames to make ordering replacements foolproof. Look up the exact bushing and dust seal part numbers for the boom swing cylinder, and verify the O-ring layout on the main control valve block. Stop wasting time returning the wrong components to the dealer. This bookmarked document opens on any device, letting you pull up the factory diagrams right in the shop and get your parts order right the first time.
