Where Honda issued more than one catalog for an engine model, use the type and serial-number tables to select the applicable edition. The years in the table identify the catalog editions. Engine fitment depends on the model, type, and serial information in each catalog.
The catalogs cover parts identification and include flat-rate labor references where listed. Step-by-step repair procedures, torque specifications, and diagnostic tests require the applicable Honda service manual.
PDF Search, Bookmarks, and File Details
Find a catalog or parts group: PDF bookmarks jump to the individual catalogs and to sections such as application tables, parts groups, and indexes. Part numbers and component names are searchable on pages with a text layer.
The download is one printable English PDF with 7,383 pages, including 7,382 catalog pages and one introductory page.
Parts Identification and Assembly Coverage
This selected preview also includes catalog references for equipment-specific assemblies and parts revisions.
- Engine and type matching: Application tables connect model and type codes to catalog codes, engine serial ranges, and carburetor identification numbers.
- Internal engine parts: Exploded views and parts lists cover cylinder heads, barrels or blocks, crankcase covers, crankshafts, pistons, connecting rods, camshafts, valve gear, governors, and gasket kits.
- Fuel, intake, and exhaust: Parts groups distinguish carburetors, air cleaners, fuel tanks and pumps, mufflers, spark arresters, and propane-specific assemblies.
- Starting and electrical controls: Recoil and electric starters, flywheels, ignition coils, Oil Alert components, switches, control boxes, wire harnesses, and GX440I and GX440IU electronic controls.
- Reduction drives and equipment assemblies: Clutched and unclutched reduction drives, transmission and hydrostatic transmission parts, PTO hardware, brake panels, batteries, and remote controls where listed.
- GX360K1 cooling and lubrication: Dedicated groups identify the timing belt and water pump, thermostat, radiator, oil pump, and duct or mounting components.
- Indexes and revisions: Illustrated indexes, part-number and part-name indexes, and appended Parts Catalogue News sheets help locate assemblies and check changes to part numbers or applicability.
Parts-counter staff, technicians, and owners with access to the engine identification markings can use the catalogs to select the correct component before ordering. This is especially useful when two carburetors or recoil starters look similar but have different type or serial-number applicability.
Reading Parts Listings
Use the exploded-view reference number to find the corresponding Honda part number, quantity, and application in the table. The catalog instructions explain blank type columns, parenthesized quantities, and entries marked N. Broken-line groupings identify assemblies listed as a complete unit.
The GX120K1 bulk-hose reference, for example, lists code 50 as a 5.0 mm inside diameter for fuel or general-purpose hose. The separate hose-type code identifies the intended application.
Flat-Rate Labor References
Flat-rate tables help estimate labor for listed operations such as cylinder-head work, replacement of internal engine components, carburetor overhaul, governor adjustment, and selected starter or ignition checks. The applicable service manual provides the work methods.
