Honda NF100MSH 2002 Parts Catalog

You’ve got an NF100MSH on the lift and the customer needs a head gasket. You pull up some aftermarket site, get a part number that doesn’t match the casting mark, and waste an hour cross-referencing. I’ve been there – that’s why OEM documentation matters. This Honda NF100MSH 2002 Parts Catalog is the factory-issued 100-page PDF that tells you exactly which bolt, seal, and shim goes where. No guesswork, no reprints. Just the parts breakdown Honda released in 2002.

CAMSHAFT/VALVE Section: Why You Need the OEM Part Numbers

Section E-3 covers the camshaft and valve train. If you’re rebuilding the top end, you need the exact camshaft part number and the valve stem seal revision code. Aftermarket catalogs often skip the revision letters stamped on the camshaft sprocket – this manual lists them. The 2002 edition includes a block check procedure on page 5 (look for “Part block and serial number check”) that tells you which serial numbers use which cylinder head gasket thickness. Don’t guess; check the block.

Does the Parts Catalog Include Fuel System Components?

Yes, section F-14 is the FUELTANK, and section E-19 covers the CARBURETOR. The catalog includes the fuel hose routing and the part numbers for the general-purpose hoses listed on page 10. If you have a fuel leak, you’ll find the correct fuel hose diameter and length specified – not generic “this should fit” garbage. The OEM diagram shows the fuel tank mounting bolts, the petcock assembly, and the vacuum line routing. Order from the factory numbers and you won’t have to wedge in a mismatched hose.

3 Ways This Catalog Saves You From Ordering the Wrong Gasket

First, the “When the parts were revised” section on page 4 tells you exactly which parts changed after initial production. A cylinder head gasket from a 2001 model might not fit a 2002 NF100MSH if Honda updated the cylinder bore. Second, the color label attachment position check (page 5) helps you verify which of the three sub-models – NF100MSH, NF100MSH2, or NF100MSH3 – you’re working on. Third, the part number index (page 86) cross-references every gasket, seal, and O-ring by address. No flipping through blurry diagrams; you go straight to the number.

CYLINDERHEAD and CYLINDER: Identifying Revisions

The CYLINDERHEAD section (E-2) and CYLINDER section (E-5) include exploded views with every stud bolt and dowel pin labeled. If you’re bolting a cylinder onto the crankcase, you’ll need the 6x12mm dowel pins from the E-5 illustration – they’re not interchangeable with the larger pins used on the CYLINDERHEADCOVER (E-1). The catalog also shows the camchain tensioner (E-4) and the one-way clutch (E-7) assembly. Having the factory illustration on your screen while you work means you spot the missing washer before the engine goes back together.

Engine Group vs Frame Group: How the Catalog Organizes 100 Pages

The catalog splits into ENGINE GROUP (sections E-1 through E-19) and FRAME GROUP (sections F-1 through F-33). Engine group covers everything from the CYLINDERHEADCOVER to the CARBURETOR and KICKSTARTERSPINDLE. Frame group includes the FRONT FORK (F-8), FUELTANK (F-14), WIREHARNESS (F-28), and even the CAUTION LABEL (F-32). The 100 pages include a part number index and a part name index – both buildable from the bookmarks. If you need a rear brake panel, go to F-12. If it’s a winker assembly, F-25. The hierarchical bookmark structure matches the printed TOC exactly.

Does this catalog include torque specs for the cylinder head bolts?

No. This is a parts catalog, not a service manual. Torque specs and repair procedures are in the separate service manual for the NF100MSH. The parts catalog only lists part numbers, exploded diagrams, and revision dates.

How do I know which of the three models (NF100MSH, 2, or 3) I have?

The catalog includes a “Models, parts catalogue codes and applicable serial numbers” table on page 6 and a color label attachment check on page 5. Match your frame/engine serial number to the table. The color label on the frame also indicates the sub-model.

If you’re tired of ordering the wrong camshaft or valve for your 2002 NF100MSH, access the factory manual and get the OEM part numbers on your bench. It’s a 100-page PDF. No fluff, no third-party assumptions – just Honda’s original data.
