Part of the Yanmar Parts Manuals.
Strip the injection pump off a 3TNE82A-EBVC and you are looking at plungers, delivery valves, a control rack, and a governor spring that all have to go back exactly as Yanmar supplied them. This parts catalog (Yanmar publication Y00B7100) gives you the exploded views and part numbers to order every one of those pieces correctly, from the pump assembly down to the stop solenoid.
The 34-page PDF covers the complete 3TNE82A-EBVC engine in 16 sections: cylinder block, gear housing, crankshaft and pistons, cylinder head, camshaft, lubrication and cooling systems, the full fuel circuit from strainer to nozzle, governor, starting motor, generator, and the gasket set.
Guessing a part number costs you a return shipment and a week with the engine apart; matching the exploded diagram costs you a minute. Print the pages you need and let them get dirty on the bench.

Yanmar 3TNE82A-EBVC Common Problems This Manual Covers
Hard starting from fuel delivery faults
Clogged strainer elements, dirty fuel, and air leaking in at loose fittings are the usual reasons this engine cranks without firing. The Fuel Pipe section diagrams the fuel strainer, taper valve, strainer element, and clamps so you can replace the whole supply path by part number instead of guessing which piece is at fault.
Manual Section: Fuel Pipe p. 26White smoke from contaminated injectors
Fouled nozzles cause white smoke, rough running, and poor power, and owners often end up replacing the injection valves outright. The Fuel Injection Pipe section breaks down the injection valve, nozzle assembly, nozzle holder, check valve, and return pipe with the numbers you need to order replacements.
Manual Section: Fuel Injection Pipe p. 24Overheating and coolant leaks
Water pump failures, worn V-belts, and stuck thermostats are common complaints on these engines. The Cooling Water System section covers the pump, O-rings, gaskets, belt, fan, and thermostat, and the catalog lists the thermostat with a 71 degree opening temperature so you can match the correct replacement.
Manual Section: Cooling Water System p. 18Oil pressure loss and bearing burn-in
Contaminated oil and neglected filtration lead to bearing damage and, in the worst cases, crank damage. The Lub.Oil System section identifies the oil pump, relief valve, filter, strainer, and oil pipes so a lubrication rebuild starts with the right parts on the bench.
Manual Section: Lub.Oil System p. 16Low compression after high hours
Worn rings and bores show up as hard starting, white smoke, and oil consumption. The Crankshaft & Piston section lists pistons with rings, piston pins, connecting rods, and big-end bearings, including 0.25 oversize pistons for engines being bored during a rebuild.
Manual Section: Crankshaft & Piston p. 14Slow cranking or dead starter
A dragging starter is easy to blame on the battery until the pinion or brushes are actually worn out. The Starting Motor section breaks the starter down to the armature, field coil, brush holder, pinion shaft, and shift lever, so you can repair the unit instead of replacing it whole.
Manual Section: Starting Motor p. 28Head gasket and valve seal leaks
Compression loss and oil in the intake tract often trace back to the head gasket, valve stem seals, or worn valves. The Cylinder Head & Bonnet section diagrams the head, gasket, valves, springs, rocker arms, and push rods so every wear item gets ordered in one pass.
Manual Section: Cylinder Head & Bonnet p. 8Frequently Asked Questions
Which engine does this parts catalog cover?
It covers the Yanmar 3TNE82A-EBVC diesel engine only, under Yanmar publication number Y00B7100. All 34 pages are specific to this engine model, organized into 16 sections from Cylinder Block through Gasket Set & Tools.
Is this a service manual with torque specs and clearances?
No. This is a parts catalog: exploded-view diagrams with part numbers and quantities for ordering and identifying components. It does not contain repair procedures, torque sequences, or clearance tables. Use it to identify and order the correct parts for your 3TNE82A-EBVC.
Does it list oversize pistons and undersize bearings for a rebuild?
Yes. The Crankshaft & Piston section lists the standard piston with rings plus a 0.25 oversize option, along with connecting rods, piston pins, and big-end bearings, and the catalog also lists 0.25 undersize main bearings in the Cylinder Block section. p. 14
Are gaskets and seals covered?
Yes. The Gasket Set & Tools section lists the complete gasket set, including the head gasket, O-rings, valve stem seals, nozzle protectors, and liquid gasket, so you can order everything needed to seal the engine back up after teardown. p. 32
