Part of the Yanmar Parts Manuals.
Somewhere between the teardown bench and the parts counter is where a 4TNE84T rebuild usually stalls: you know exactly which piece failed, but not the number Yanmar printed on it. This catalog settles that. Publication Y00R4551 is the factory parts book for the Yanmar 4TNE84T-SA, 4TNE84T-G1A, and 4TNE84T-G2A turbocharged diesels, 34 pages of exploded assemblies keyed to genuine part numbers.
Coverage runs from the cylinder block, cylinder head, crankshaft, and pistons through the camshaft and gear train to the turbocharger, the lube oil and cooling water systems, fuel injection valves and nozzles, the fuel strainer, governor and regulator linkage, starter, generator, wiring harness and instrument panel, and the full gasket set.
Every day the engine sits apart waiting on a part that came back wrong is a day you do not get back. Download the PDF, find the assembly, pull the exact number, and order once.
