Hanix H08B Parts Catalog

If you have ever ordered a part for a H08B based on some aftermarket catalog number and ended up with a seal kit that doesn’t fit the boom cylinder, you know the frustration. That waste of time and money stops here. This is the actual Hanix factory Parts Catalog – 152 pages of OEM drawings, part numbers, and interchangeability codes. No third-party guesswork. No reprints. This is the document the dealer uses when you call in with a serial number. Page 4 has the index that breaks down every section from WORK EQUIPMENT to ELECTRIC SYSTEM. You look up the exploded view, match the reference number, and order the correct part. Period.

WORK EQUIPMENT Breakdown (Sections A11-A12)

The catalog starts with the arm, boom, and bucket linkage – sections A11 and A12. Each assembly is drawn with reference numbers keyed to the parts list. You get the OEM part number, quantity, and a remarks column that tells you if a part is supplied only as an assembly. See the asterisk (*) and diamond (◊) symbols? Page 3 explains that – * means assembly part, ◊ is component. If you need a single bushing that only comes in the assembly, you know before you order. That saves a return trip to the parts counter.

Upper Frame and Control System Routing

Swing frame (B10), floor plates (B15A/B), control systems (B21 through B24) – these sections cover the joystick linkages, pedal assemblies, and the floor structure. The diagrams are straight from the Hanix production line. You get the correct bolt lengths for the floor plate mounting, the shim thickness for the control valve linkage. Automotive Industry Overview might cover general hydraulics, but this catalog gives you the exact Japanese craftsmanship specs for your H08B.

Lower Machine and Track Frame – Section C11-C12

Track frame components – sections C11 and C12 have 4 pages total (pages 48-51) showing the roller, sprocket, idler, and track chain breakdown. If you are rebuilding an undercarriage, you need the correct part numbers for the floating seals and the track adjuster assembly. This catalog lists them with interchangeability codes: A means new part replaces old but not vice versa, B means no interchange. Do not mix that up – a B-code part will bolt up wrong and cost you a set of rollers.

Power Unit and Hydraulic Component Specs

Engine mount and cooling package are in D21-D23. Then the real meat – hydraulic components from F11 (control valve) through F56 (selector valve). Each cylinder – boom, arm, bucket, swing, dozer, extension – has its own exploded view with seal kit part numbers. The pump, travel motor, turning motor, and swivel joint are all there. You need the O-ring size for the swivel joint? It is in section F40 on the diagram. No need to measure a worn seal and guess.

Electric System – Section G10

Only one section for the electrics, but it covers the wiring harness and component layout for the H08B. The Automotive Industry Overview does not help with a mini excavator starting circuit. This catalog does – starter motor, alternator, fuse box, and the master disconnect switch. If you are chasing an electrical ghost, having the factory part numbers for the relays and switches eliminates the guesswork.

How to Use the Parts Catalogue – Page 3 Rules

Page 3 is critical. It explains the interchangeability marks (A through Q), the abbreviations (ASSY, CYL, HYD, etc.), and how to read the part number column. A line drawn through a part number means replace it with the part number below. Ignore that and you order a discontinued part. The catalog also lists applicable machine serial numbers for each part – you verify your H08B serial before ordering. That is the difference between getting the right hydraulic breaker piping (section E11) and getting a bracket that hits the track.

Why OEM Beats Aftermarket for the H08B

I have seen aftermarket parts catalogs that mislabel a boom cylinder seal as fitting both H08B and H55DR. They are not the same. The H08B uses a specific piston rod diameter. The OEM catalog calls it out. The only way to get the right number is from the Hanix Parts Catalog – 152 pages, direct from the factory print. HANIX H08B Parts Catalog is the foundation. Pair it with HANIX H08B Service Manual for disassembly and torque specs, and if you also work on larger models, grab HANIX H55DR Parts Catalog – Section: Swing Ar..

Does the catalog include hydraulic hose part numbers?

Yes. Sections E10 through E30 cover all hydraulic piping – work equipment piping, breaker piping, upper frame piping, chassis frame piping. Each hose assembly has a part number and length. You can order pre-made hoses instead of making custom ones.

How do I find the correct part if my H08B has a serial number outside the ranges listed?

That is a problem I see a lot. The catalog lists applicable machine serial numbers for each part. If your serial is older or newer than the range, the part may have been superseded. Look for the interchangeability code A (new replaces old). If the code is B, you need to contact Hanix dealer support with your serial. The catalog gives you the starting point – you still need to verify with your actual machine. But without this catalog, you are guessing blind.

Stop ordering blind. Stop returning parts that don’t fit. Access the Factory Manual and get the correct Hanix H08B part numbers from the only source that matters – the OEM Parts Catalog.
