Part of the Yanmar Parts Manuals.
All 42 pages of this Yanmar TB235 / 3TNV88-BPTB2 Parts Catalog zero in on the 3TNV88-BPTB2 engine (cab) and 3TNV88-BPTB1 (canopy) variants used in the Takeuchi TB235. You get exploded-view figures stepping through every major assembly: cylinder block, gear housing, flywheel, cylinder head, camshaft, crankshaft and piston, fuel injection pump, governor, injectors, fuel line, starting motor, alternator, and gasket sets. Each figure pairs with a numbered parts list so you can identify components, confirm OEM part numbers, and cross-reference superseded items without a phone call to the dealer. Sizing data is baked right into the lists: main metal, thrust metal, piston pin, and ring sets all show 0.25 mm undersize and oversize options so your order lands correct the first time. Chasing a part number across three websites ends now. Bookmarked by assembly, searchable by keyword, and downloadable in seconds.
