Yamaha T135HC Parts Catalog

You ever order a part based on a third-party list and end up with a cylinder that doesn’t match your crankcase threads? I’ve seen that more times than I care to count. That’s why you need the real thing – a factory Yamaha T135HC Parts Catalog. This 65-page document comes straight from Yamaha Motor Co., Ltd., printed in Japan. It lists every single part by number, with exploded diagrams that show you exactly where it goes. No guesswork. No aftermarket cross-reference that’s wrong half the time. You open this catalog, you find the part number, you order it. Done.

Inside the Engine Section: Cylinder, Crankshaft, Valves, and Camshaft

Flip to page 1 and you’re looking at the cylinder head assembly with every bolt, gasket, and shim listed. The Engine section runs from cylinder head through the crankshaft & piston (page 3), valve train (page 4), and camshaft & chain (page 5). If you’re rebuilding the top end on a T135HC, you need the exact part numbers for those valve keepers, cam sprocket bolts, and crankshaft bearings. The catalog gives you the part number, description, and quantity per assembly. No fluff – just the data you need to order from a Yamaha dealer.

Water pump, oil pump, intake, carburetor, exhaust, crankcase, covers – it’s all there. The TOC shows every subsection by page number. You won’t waste time flipping through unrelated sections.

Chassis and Electrical: More Than Just Engine Parts

Frame, fenders, suspension, brakes, wheels, steering – the chassis section starts on page 23. Need a rear brake caliper rebuild? Page 36 lists the piston, seals, and bleeder screw with original part numbers. The electrical section (pages 48-56) covers the generator, starting motor, flasher lights, meter, headlight, taillight, and handle switches. If you’re chasing a wiring issue, the electrical sheets show connector views and component locations. That saves you from ordering the wrong switch assembly because you guessed the color code.

Why the Numerical Index Saves You from Ordering Wrong Parts

Page 57 starts a numerical index. That means you can take the part number you scribbled on a napkin and look it up to verify it fits your T135HC. The index covers all part numbers listed in the catalog. If you have a 2F5-83310-60 front flasher light assembly, you can cross-check it in seconds. For context on how the internal combustion engine works, the Internal Combustion Engine”>Internal Combustion Engine Wikipedia article explains the principles, but this catalog tells you which piston ring set to order.

Speaking of automotive industry supply chains, the Automotive Industry Overview”>Automotive Industry Overview page gives background on why OEM catalogs are the gold standard – aftermarket catalogs often use outdated supersessions.

65 Pages of Genuine Yamaha Part Numbers

That’s it. 65 pages. No more, no less. Every page is scanned from the original Yamaha publication – first edition, December 2010. The cover says “YAMAHA GENUINE Parts & Accessories.” The foreword explains the abbreviations: UR (use specified), UN (use as needed), AP (alternate parts), LM (locally made). If you see an asterisk next to a reference number, that part was modified after the first edition – you’d need to check Parts News for superscript updates.

Color codes for graphics are listed on page 4. The model is the T135HC (50C1) Indonesia 5-speed. Frame and engine serial numbers are provided to confirm exact applicability.

Using This Parts Catalog the Right Way

Don’t try to assemble parts using the illustrations – the foreword explicitly says “not to be used for assembling.” That’s what the service manual is for. This catalog is for ordering. Write down the part number exactly as shown. Quote both number and name when you call the dealer. Do not rely on the OEM torque specs or assembly sequences here – those belong in the service manual. The catalog’s job is to make sure you get the right cylinder, crankshaft, valve, and camshaft components the first time.

OEM vs Aftermarket Catalog: A Technician’s Verdict

I’ve seen aftermarket catalogs that list a part number that was superseded six years ago. Or they omit the “dot” items – those sub-components that come in an assembly but can be ordered individually. You order a clutch assembly thinking it’s complete, and you’re missing the friction plates. This Yamaha catalog shows the exact exploded view with every sub-component listed with a dot prefix. That’s why I keep OEM catalogs on my bench. They’re not pretty. They’re not user-friendly in the modern marketing sense. But they’re correct.

Can I use this catalog to find torque specs for head bolts?

No. This is a parts catalog, not a service manual. Torque values are in the service manual. Get both.

How do I decode the color codes listed for graphics?

Page 4 has a table with abbreviation, color name, and color code. Example: BMC = Blue Metallic C 0775. The model colors are marked with an asterisk. These are for identifying the correct tank graphics or side covers when ordering painted parts. The catalog tells you which graphic belongs to which color option for the T135HC.

Does the catalog include the 5-speed transmission parts?

Yes. The cover says Indonesia 5 Gears Speed. The transmission section starts on page 19, followed by shift cam & fork (page 21) and shift shaft (page 22). Every gear, bearing, and shift fork is listed with its OEM part number.

What if I need a part that shows “LM” in the remarks column?

LM stands for Locally Made. That part needs to be ordered from local suppliers rather than Yamaha directly. The catalog lists it so you know the part exists but you source it differently. Check with your local dealer for availability.

Stop wasting money on wrong parts. Access the Factory Manual – this 65-page OEM Yamaha T135HC Parts Catalog – and get the genuine part numbers you need.
