Part of the Hitachi Parts Manuals.
This 289-page Hitachi EX33U parts catalog PDF (OEM #P1BN-1-1) maps every assembly on your EX33U compact excavator, from swing bearing and track frame to boom, arm, and bucket group. You get exploded views with factory part numbers for the full undercarriage (front idlers, upper and lower rollers, rubber and steel crawler adjusters), plus complete breakdowns of the piston pump, control valve, pilot valves, and every cylinder on the machine. Cab and canopy hardware, electric parts, and the wire harness each get their own illustrated sections. Bucket options run from the 300mm 0.045 to the 600mm 0.11, and track-links come in 300G, 400G, and 400A configurations, all with exact part callouts. Ordering the wrong seal kit twice gets old fast. Bookmarked and text-searchable; type a part name, jump straight to the diagram, and order right the first time.

Hitachi EX33U Common Problems This Manual Covers
Hitachi EX33U bucket teeth and adapters worn, unsure which bucket parts list applies
Measure your bucket width first. The catalog splits buckets by size: 300 mm on page 173, 350 mm on page 175, 450 mm on page 177, 520 mm on page 179, and 600 mm on page 181. Match the width, then pull tooth adapter, stopper, and bolt numbers from that exploded view.
Manual Section: Bucket 0.08 _Jis94_ (450Mm Wide) p. 177Steel track links stretched and shoes worn, replacement track-link assembly number unclear
Measure shoe width across the pad before ordering. A 300 mm shoe takes the Track-Link 300G assembly on page 145; 400 mm shoes use the 400G list on page 147 or the 400A list on page 149. For rubber tracks, find the complete shoe assembly on page 143. Order the master pin with the link set.
Manual Section: Track-Link 300G p. 145Boom cylinder weeping at the rod, can't tell which seal kit fits
Check your machine configuration first: canopy units use the boom cylinder parts list on page 279, cab units the list on page 281. Verify the rod diameter in millimeters against the removed rod, then order the packing, ring, and dust seal from that exploded view. Confirm the serial number range printed on the parts list.
Manual Section: CYL.;BOOM p. 279Travel weak on one side, final drive leaking, seal set numbers unknown
Remove the travel motor cover and match parts against the oil motor exploded views: case, pinion shaft, ball bearing, and oil seal on page 253, planetary and sun gears on page 255, relief and check valves on page 257. Measure your shim set thickness in millimeters and compare it with the listed set before ordering.
Manual Section: MOTOR;OIL p. 253Sluggish boom and arm response after hydraulic service, wrong pilot filter element suspected
Inspect the pilot line filter shown on Pilot Pipings (1-1), page 71, which lists the housing, element, and spacer as separate items. Cross-check the suction filter and O-rings under Oil Tank on page 30, and measure the old element's outer diameter in millimeters against the replacement before installing it.
