Honda GX270 Engine Parts Catalog Collection, 2006 (P/N 13ZH90E9)

Use each catalog with its corresponding Parts Catalogue News sheets for corrected illustrations, part-number changes, application and serial corrections, and added type coverage.

Parts-catalog scope: This collection identifies repair parts and applicable labor operations; it is not a step-by-step repair manual. The FRT sections refer to separate Honda service literature for work methods, inspection procedures, settings, and final repair checks.

Searchable PDF with Catalog Bookmarks

Text search and section access: Searchable catalog text and embedded PDF bookmarks provide access to the six publications, illustrated parts blocks, indexes, and included News sections.

One printable 818-page PDF, including 140 Parts Catalogue News pages, 12 blank pages, and one separate preliminary page.

Engine Assemblies, Fuel Systems, and Type-Specific Parts

The following selected catalog coverage highlights the main assemblies and reference material. Additional illustrated entries include labels and tool groups.

• Internal engine parts: The six illustrated indexes contain 197 parts blocks, including cylinder heads and barrels, crankcase covers, crankshafts, pistons and connecting rods, and camshafts.

• Fuel and air systems: Carburetor, air-cleaner, and fuel-tank arrangements with exploded views, Honda part numbers, required quantities, and catalog-type applicability.

• Starting and electrical: Recoil starters, fan covers, flywheels, ignition coils, starter motors, control boxes, and harness arrangements separated by catalog type.

• Exhaust and controls: Mufflers, exhaust pipes, muffler covers, engine controls, and auto-throttle assemblies with individual repair-part listings.

• Output and reduction: Straight, splined, threaded, and tapered shafts with applicable reduction, clutch, coil, Oil Alert, starter, fuel-tank, and control-box combinations.

• Parts and labor references: Model/type/engine-serial/carburetor-ID tables, serial breaks, part-number and part-name indexes, and FRT/LON replacement-operation references.

Suited to mechanics and parts staff who can match engine types, serial numbers, and carburetor IDs before selecting replacement parts.

Serial-Specific Parts Identification

A GX270 model name by itself is not enough to order from these catalogs. The opening tables tie each parts catalog code to the stamped engine serial number and, for carburetor groups, the stamped carburetor identification number.

Individual listings show the exploded-view reference, Honda part number, description, required quantity, applicable type, and serial break. Selective codes L1, Q1, Q2, R1, S1, V1, and W1 are listed separately from propane HAP, RXP, VXP, and VXQP types.

Propane HAP, RXP, and VXP applications split between GDAD-1000001–1099999 and the corresponding /A catalog versions beginning at GDAD-1100001. VXQP is listed for GDAD-1000001–1000029.

Broken-line boxes in the exploded views identify complete assemblies whose component parts are also listed separately. Dotted-line and arrow references direct the reader to related blocks. Together with the part-number, part-name, and illustrated indexes, this gives mechanics three practical routes to the correct repair part.

Engine Housings and Equipment Variants

The main GX270/propane publication has 55 illustrated blocks, including six crankcase-cover layouts, four carburetor blocks, seven air-cleaner layouts, six muffler layouts, four fuel-tank layouts, three control-box groups, and three reduction groups.

Cylinder-barrel assemblies are separated into standard, Oil Alert, self-starter, balancer, and combined builds. Governor hardware, oil seals, bearings, and gasket kits are itemized alongside the engine internals.

Other publications add their own equipment splits: semi-dry, oil-bath, and dual air cleaners for GX270H; standard and silent mufflers, spark-arrester provisions, and exhaust-pipe differences for GX270T; and standard, silent, or generator mufflers for GX270UT/RT.

These combinations are tied to type codes and should not be selected from shaft appearance or engine displacement alone. Special-equipment listings also cover emergency-stop switches, kill switches, sub-harnesses, and under-frame parts.

News Supplements and Parts-Selection Cautions

Added types include GX270H VSP/VX, GX270U HKS8, GX270R VNT2/VW12, and GX270UT PXED/QHB4/QXUZ. Their News sheets describe the differences and identify the base types to use for parts not listed in the supplement.

Do not match parts by illustration shape alone; Honda states that the drawings are reference aids and may differ from the actual components. Cylinder-barrel and crankcase-cover assemblies vary with Oil Alert, starter, balancer, governor, and bearing layouts, so a visually similar housing can be wrong for the build.

The hose section specifically prohibits substituting general-purpose or vinyl hose for fuel hose because the wrong hose creates a fuel-system safety hazard.

Factory Labor References

FRT and LON entries support repair planning by linking exploded-view reference numbers to factory labor operations. The prefaces list cylinder-head removal and installation, valve-clearance adjustment, throttle/governor adjustment, and carburetor idle adjustment.

Other entries address engine-oil inspection and change, air-cleaner service, spark-arrester cleaning, spark-plug service, and carburetor overhaul. These are labor-operation references rather than instructions for performing the work.

Selected Reduction-Part Identification Details

The GX270UT LXE8 and LXU reduction listings specify a 14-tooth drive sprocket (23110-ZE2-610) and a 28-tooth PTO shaft (23710-ZE2-610). Both entries are tied to those catalog types, alongside the matching chain-case and bearing parts.
