Part of the Hitachi Parts Manuals.
Hunting a part number for your Hitachi EX15? This 265-page Hitachi EX15 parts catalog PDF (OEM #P1A7-1-5) maps every component on the mini excavator, from track frame to boom tip. You get exploded views paired with numbered parts lists for the engine group, hydraulic pumps and motors, control valves, cylinders, cab and canopy hardware, plus the full undercarriage: idlers, rollers, adjusters, and both steel and rubber crawler track links. Piping runs get the same treatment; main, pilot, and travel circuits are broken down hose by hose, fitting by fitting. Need to shim a motor rebuild? The catalog lists 0.05 mm and 0.1 mm shims, and separate sections cover every bucket option from 250 mm to 500 mm wide. Ordering the wrong seal kit twice gets old fast. Bookmarked and text-searchable; type the component name, land on the exploded view, order once.

Hitachi EX15 Common Problems This Manual Covers
Hitachi EX15 swing motor leaking at pinion shaft, can't identify correct oil seal and shim sizes
Check the oil motor exploded view on page 228. The pinion shaft oil seal, ball bearing, and shims are itemized there; shims come in 0.05 mm, 0.1 mm, and 0.3 mm thicknesses, so measure the originals before ordering. Match the item numbers against the swing device mounting hardware on page 26.
Manual Section: Motor;Oil (1_3) p. 228Blown fuse keeps killing the monitor and gauges, not sure which amperage the fuse box takes
Verify ratings against the Electric Parts (2) list on page 100 before buying replacements; it shows 5A and 15A fuses for the fuse box and monitor circuits. Record the item number for each slot, then order straight from the parts list instead of guessing amperage at the parts counter.
Manual Section: Electric Parts (2) p. 100Ordering replacement bucket teeth and pins, five bucket widths listed and the parts look identical
Measure your bucket cutting width first; the catalog carries separate listings for 250 mm, 350 mm, 410 mm, 450 mm, and 500 mm buckets. For the 450 mm bucket, pull tooth, bolt, nut, boss, shim, and plate item numbers from the assembly breakdown on page 152, and order only from that page.
