Part of the Yanmar Parts Manuals.
All 51 pages of this 4TNV98T-ZSTBW, P-T175WECF Parts Catalog are built for one job: finding the right part number before you call the counter. Inside, exploded-view assemblies walk you through every system on this turbocharged diesel, including the cylinder block, gear housing, flywheel housing and oil sump, cylinder head and bonnet, suction manifold and air cleaner, exhaust manifold and silencer, camshaft and driving gear, turbine, crankshaft and piston, hydraulic pump, lube oil system, lube oil line, cooling water system, fuel injection pump, governor, fuel injection valve, fuel line, starting motor, generator, electric parts, and a complete gasket set. Each figure pairs a labeled exploded diagram with its numbered parts list for fast component identification. Cross-reference your 12V/3KW starting motor assembly or confirm the V-Belt (B45) straight from the factory drawing. Stop guessing at part numbers. Bookmark your assembly, grab the OEM number, place the order.
