Honda GX670 2005 Parts Catalog

You ever order a part for a GX670 and get the wrong one because some online parts diagram was off by a letter? That stops the second you open this 211-page Honda GX670 2005 Parts Catalog. Honda Motor Co. printed this in 2005, and every page comes straight from the factory – no reprints, no aftermarket guesswork. I’ve been turning wrenches since before some of you were born, and I’ll tell you: if you don’t have the right part number, you’re wasting time and money. This catalog gives you the exact part numbers, exploded views, and reference codes for every Engine component, Fuel system piece, Cylinder assembly, and Crankshaft group. You need the flat rate service time? It’s on page 11. You need the part number index? Page 84. That’s the kind of spec-level detail a lazy aftermarket PDF won’t give you.

CYLINDER HEAD and CRANKSHAFT: Where the Real Meat Is

The Engine Group section (starting page 20) breaks down every subassembly like you’re looking at the engine on your bench. The Cylinder Head is E-2, Cylinder Barrel is E-3, Crankshaft is E-7. Each one has its own exploded diagram with part numbers right next to the drawing. You’re not flipping back and forth trying to match a blurry image to a list. You see the part, you see the number, you order it. The Crankshaft page – E-8 in the TOC – includes the oil seal and bearing part numbers. That alone saves you a phone call to the dealer.

7 Systems Covered Under Engine Group

Don’t think this is just a handful of diagrams. The catalog covers: Cylinder Head, Cylinder Barrel, Crankcase Cover, Crankshaft, Piston/Connecting Rod, Camshaft, Recoil Starter, Fan Cover, Carburetor (three separate sub-sections), Air Cleaner (standard and snorkel), Muffler (high-R and high-L), Fuel Pump (two sections), Flywheel, Ignition Coil, Starter Motor, Control (four sub-sections plus auto throttle), Control Box, Oil Cooler, Labels, Tools, Combination Switch/Fuel Pump, Control Cover/Fan Cover Protector, and a Winter Kit. That’s not a list – that’s the actual table of contents from the factory. Each section has its own address code (like E-14-1 for Carburetor 2) so you can go straight there.

Does This Catalog Cover the Fuel System?

Yes, and it does it right. The Fuel system section is E-18 and E-18-1 for the Fuel Pump. There’s also a dedicated section on page 10 for Fuel Hose, General Purpose Hoses, and Vinyl Hose – with the exact Honda part numbers for each hose diameter and length. If you’re replacing a fuel line on a GX670-powered piece of equipment, you don’t guess the inner diameter. You look it up here. The catalog also lists the combination switch and fuel pump on E-40, which includes the electrical connections. No more splicing random wires hoping it works.

Parts Catalog News: Why You Need Revision Updates

The first few pages of this catalog include a section called “Parts Catalogue News” – pages 001 through 046. These are the official sales parts information updates for specific types: TW1, TKW1, TDW1, VAY. Honda issued these revision notices after the initial printing, and they’re printed right in the catalog. If you have a late-model GX670 with a specific type code, you need to check these pages. The catalog itself states that modifications or additions will be issued as revised editions. You’re getting the base 2005 version, but that News section covers changes through the production cycle. That’s something a reprint website won’t copy.

How to Use the Illustrated Index and Part Number Index

The catalog gives you two ways to find any part. First, the Illustrated Index (page 16) shows a picture of the engine with callouts linking to each sub-group address (E-2, E-3, etc.). Second, the Part Number Index (page 84) lists every part number in numerical order, with the address and page reference. For example, part number 15212-ZW9-000 points to address 1-C14 on page 30. You look up the number, flip to the address, and see the diagram. The Part Name Index (page 87) lists alphabetically. No guesswork, no searching through blurry scans.

Audience Fit: Who Should Buy This

If you are a shop owner or a home mechanic rebuilding a GX670, this catalog is your parts bible. A DIYer who’s trying to order a replacement carburetor gasket set needs this to get the right kit number. A professional mechanic who bills by the hour can’t afford to waste time cross-referencing aftermarket sites – this catalog gives you the Honda OEM number in seconds. The flat rate service time on page 11 is a bonus: it lists standard labor times for common repair jobs, which helps you quote work accurately. Beginners: don’t avoid this because it’s a parts catalog. The exploded diagrams teach you how the engine goes together better than any YouTube video. Pair it with the Honda GX670 GX620 2007 User Manual – OEM Factory Specs for the complete repair procedure. Also check the Honda VFR750F 1994 Parts Catalog – OEM Factory Parts Breakdown if you work on motorcycles, or the Honda VFR400R VFR400Z 1989 Parts Catalog – OEM Factory Manual for older VFR models.

Source Validity: Why OEM Beats Aftermarket

I’ve seen aftermarket parts catalogs that use generic drawings and renumbered part numbers. This is an original Honda publication, printed in 2005 by Honda Motor Co., Ltd. The document includes the statement: “This parts catalogue was prepared based on the latest information available as of September 20, 2005.” Every part number starts with the genuine Honda prefix. The illustrations are schematic but accurate for identification. You’re not getting a third-party reinterpretation – you’re getting the same document a Honda dealer uses. For context on why OEM documentation matters in the broader Automotive Industry Overview, consider that a wrong part can cause a $2,000 engine failure. Even something as simple as a Automotive Battery has terminal specs you can’t fake; imagine the hazard of misidentifying a fuel pump part. Trust the factory print.

How many pages does the catalog have?

211 pages including covers and index.

Does it include torque specs for the cylinder head bolts?

No. This is a parts catalog, not a service manual. It lists part numbers, diagrams, and flat rate service times (page 11). For torque specs, you need the Honda GX670 user manual or service manual.

Can I use this catalog to order parts for a GX670 propane engine?

Yes. The cover explicitly lists “GX670 [PROPANE ENGINE]” as a separate model. The catalog includes propane-specific parts in the carburetor and fuel system sections. Check the Parts Catalogue News for propane type updates.

How do I verify I have the correct part number for my engine’s serial number range?

Use the “How to check the part block and serial numbers” section on page 5, then reference the “Models, parts catalogue codes and applicable serial numbers” on page 6. Match your engine’s type code (e.g., TW1, TKW1) to the correct sub-diagram. This process is explained step-by-step in the manual’s index.
