Hitachi Sumitomo SH330-5, SH330LC-5, SH350HD-5, SH350LHD-5 Parts Catalog

You’ve got a Hitachi Sumitomo SH330-5 on the pad and a part number that doesn’t match the bucket pin bushing. Or you’re rebuilding the swing drive on a SH350LHD-5 and the aftermarket catalog lists a seal that’s a sixteenth off. That’s the exact moment you realize why ordering from a third-party parts list costs you a second teardown. This Hitachi Sumitomo SH330-5, SH330LC-5, SH350HD-5, SH350LHD-5 Parts Catalog is the only way to get the factory exploded views and genuine part numbers — no guesswork, no reprints.

LOWERS: Undercarriage Parts Breakdown

Chapter ローワー (LOWERS) covers the track frames, rollers, sprockets, and idlers across all four models. Every bolt, shim, and seal is indexed to the serial number ranges listed on page 1: 330A5-1101~ for the SH330-5, 350A5-1101~ for the SH350HD-5. The area map on page 81 (AREA DA) shows where each component sits on the machine. If you’re swapping a track adjuster, you’ll see the exact retaining ring and o-ring dimensions — no aftermarket nonsense.

Swing Frames and REV.EQUIPMENT: Rotation Assembly

The センカイフレーム (SWING FRAMES) section lists the swing gear, bearing race, and mounting hardware. Alongside it, センカイウチ (REV.EQUIPMENT) includes the swing motor, brake valve, and piping. Need the pressure relief valve setting? That’s not in this parts catalog — you want the service manual for that. But if you need the exact hex head plug or internal snap ring, the illustration and part number are right here. Each item references a book number like WCLA330A51BH000 for the SH330-5 base model.

ENGINES and Controls: Matching the Right Harness

Section エンジン (ENGINES) covers the Isuzu or Cummins base engine components — gaskets, filters, hoses. The コントロール・ライン (CONTROLS & LINES) chapter breaks down the pilot lines, solenoid valves, and linkage. If you’re restoring a SH330LC-5 that had a cab fire, the control line harness is listed by area code: check AREA DC on page 82 for the specific connector. The book WCLA330A51LC000 is your exact match.

ATTACHMENTS: Backhoe and Crane Configurations

Two separate attachment chapters exist: アタッチメント (クレーン・他) for crane lift options, and アタッチメント (バックホー) for the standard backhoe bucket linkage. Each page shows the stick, boom, cylinder, and pin. For the SH350LHD-5, the heavy-lift boom uses different pins than the standard SH350HD-5 — the parts index at the back (AREA ZA on page 95) cross-references the part numbers. Don’t guess; look it up.

651 Pages, 11 Chapters, Zero Room for Error

This Parts Catalog is 651 pages of factory-original drawings. It’s not a reprint — it’s the same PDF the dealer uses to order parts. Every chapter from LOWERS to インナーパーツ (INNER PARTS) is here. The index covers AREA DA through ZA, and each area code lists the page number (e.g., AREA DJ on pages 84-85). Combined with matching serial number prefixes, you can order the correct final drive seal or track roller without pulling the whole assembly a second time. Sumitomo SH330-5 SH350HD-5 Technical Manual – Section: Work Range Diagram (Sh330 and Hitachi Sumitomo ZAXIS850-3 Series Parts Catalog – 451 Pages are additional resources if you need torque specs or larger machine coverage. For the smaller ZAXIS line, see Hitachi Sumitomo ZAXIS 600-650LCH Parts Catalog – 162 Pages.

Still on the fence about OEM documentation? Read the Automotive Industry Overview to understand why factory specs matter. Or check the Automotive Industry Overview for context on supply chains. Bottom line: use the manual the guys who built the machine wrote.

Does This Cover All Four Serial Number Ranges?

Does this manual work for SH330-5 and SH330LC-5?

Yes. The same book covers SH330-5 (serial 330A5-1101~), SH330LC-5 (330LC-1101~), SH350HD-5 (350A5-1101~), and SH350LHD-5 (350LA-1101~). Each model has its own book number listed on page 5, but all parts are in one volume.

What about the swing cab wiring?

Go to the デンキヒン (ELECTRIC PARTS) chapter. The cab and house harness are shown in AREA DR (page 91). Match the part number against your machine’s serial — aftermarket harnesses often skip the ground splice that SH350HD-5 units need. This manual lists the OEM terminal and connector shells so you can rebuild it correctly.

Access the Factory Manual. You’ll have the same diagrams the dealer’s parts counter uses. One correct part number beats two returns every time.
