Honda TRX350FE, TRX350FM, TRX350TE, TRX350TM 2003 Parts Catalog

I’ve been wrenching on Honda fourtrax machines since they first rolled off the line. You’re holding a parts catalog that’s direct from American Honda Motor Co., Inc., August 2003. If you’ve ever ordered a cam chain tensioner only to get one that didn’t fit because the VIN prefix was off, you know the pain. This Parts Catalog kills that guesswork dead. It’s 148 pages of factory-sourced part numbers, exploded diagrams, and serial number cross-references for the Honda TRX350FE, TRX350FM, TRX350TE, and TRX350TM. You’re not getting a reprint or a third-party compilation. The scan you access is the original fiche version (14HN44E1M). The paper edition came from Helm. This is what the dealer parts counter used.

How to Use This Catalog – Reading the Page Breakdown

Flip to the introduction starting at page 4. The catalog page breakdown is explained: reference numbers tie to illustrations, description abbreviations (ASSY., COMP., STD.), model-ID codes, and serial number ranges. You’ll see columns: Ref, Description, MODEL-ID, From Serial Number, To Serial Number, Area, Org, Qty, Part Number, H/C. If you skip reading this, you’ll misinterpret the relationships between parts and supersessions. The “KEY TO CATALOG PAGE BREAKDOWN” spells out every abbreviation. NI means not illustrated. Don’t assume a part number is correct just because the picture looks like what you pulled off the engine. Cross-check the model-ID and serial range.

Engine Section: Parts Breakdown for the 329cc Powerplant

The Parts Group kicks off with the ENGINE SECTION starting at 1-C1. This covers cylinder head cover sets, crankcases, piston/rings, cam chain, oil pump, and the entire internal rotating assembly. For a TRX350FE Rancher 4×4 ES, the electric shift motor and related hardware are listed with their unique part numbers. You get the part numbers for the A.M. (attaching mark) bolts and washers. If you’re pulling the head because of a coolant leak, you’ll find the cylinder head gasket and the O-rings for the oil passages. The catalog even lists the bulk hose part number pattern in the introduction if you need generic fuel or vent hose. Page 73 of the Engine Section (roughly) has the crankcase components. No torque values here – this is a parts manual, not a service manual – but you get exact Honda part numbers to order the correct seals and bearings.

Frame Section: Chassis, Suspension, and Body Panels

After the engine, the FRAME SECTION begins at 1-E1. This covers the main frame, front and rear fenders, footrests, seat, handlebar components, front and rear axles, wheel hubs, brake panels, and cables. If you’re replacing the rear brake cable on a TRX350TM Rancher, the part number is here. The section also includes the battery (Yamaha? No – Honda spec) and the starter system. For the ES models (TRX350FE, TRX350TE), the shift motor and related wiring are in this section under the sub-transmission area. The exploded diagrams show how every bracket and bolt assembles. Use the description index at the back (DESCRIPTION INDEX starting 1-H1) if you don’t know the part number but know the name.

Serial Number Locations – Why They Matter for Parts Ordering

Page 5 covers the LOCATION OF SERIAL NUMBER. Honda stamps the frame number and engine number in specific spots. The four models have different serial number prefixes. For example, the TRX350FE (4×4 ES) runs a different frame serial series than the TRX350TM (2WD manual shift). The catalog lists those ranges on page 7 under SERIAL NUMBERS. Ordering a part without confirming your serial number is a waste of time. I’ve seen guys order a shift drum for a TRX350TE using a part number that only fits the early ’03 production because they didn’t check the serial break. This catalog prevents that. It’s the same data the dealer uses. Don’t trust a random online cross-reference. Use the factory numbers.

Construction of VIN – Decoding Your Honda’s Identity

Page 8 breaks down the CONSTRUCTION OF VEHICLE IDENTIFICATION NUMBER. Every character position tells you model, engine type, and assembly plant. The VIN is critical when you need to verify if that used front axle you found will fit your TRX350FM. The catalog’s master index (page 18) tells you which page each component lives on. For instance, if you need the COLOR TABLE (page 9) to match paint codes for a plastic panel, that’s there too. All of this is part of the 148-page OEM tool you’re getting.

The Parts Catalog is not a service manual – it won’t tell you how to rebuild the carburetor. But if you need to order that carburetor assembly with the correct gasket set, this is the only doc that guarantees the part numbers are right. The Automotive Industry Overview might talk about trends, but this catalog is about specific numbers. The Automotive Battery referenced here is just one component; the catalog lists the battery model and holder parts.

FAQ

Does this manual cover the 2003 model only? The cover says 2003, but my 2004 Rancher has the same frame. Will it work?

This catalog is dated August 2003 and covers the 2004 model year editions (TRX350FE’04, etc.). If your machine is a 2004 model but built after that date, there may be revisions. Always check your frame and engine serial numbers against the ranges listed in the catalog. Honda made running changes mid-model-year. The catalog is accurate for the production represented by those serial number breaks.

Can I use this to identify part numbers for an engine rebuild?

Yes, for the engine section you get every internal part from the crankcase to the cylinder head cover set. But remember, a parts catalog does not include torque specs or assembly sequences. You need a factory service manual for that. Use this catalog to order the correct seals, gaskets, bearings, and bolts.

Are torque specs included in a parts catalog?

No.

How do I find the correct part number for my specific VIN?

Start by locating your frame serial number (page 5). Then turn to the serial number tables on page 7 to find which model-ID code applies. Next, go to the appropriate Parts Group section (Engine or Frame) and look for the component. Each row includes a From and To serial number range. Verify your number falls within that range. Use the MASTER INDEX (page 18) to find the right page. Cross-reference with the DESCRIPTION INDEX (4-1) if needed.

152 of those pages are actual part group illustrations and index. Every page is a direct scan of the original OEM document. No third-party redraws, no ambiguous callouts. If you’re restoring a 2003 Fourtrax or just need to fix one that’s been sitting, this catalog saves you from buying the wrong part twice. Access the Factory Manual and keep it on your tablet or printed at the bench. Your next order will be right the first time.
