Part of the Yanmar Parts Manuals.
Halfway through a teardown of a Yanmar 3TNV80F-SPAMM, the job usually stalls on one small number: the thrust bearing behind the crank, the O-ring under the gear case cover, the delivery valve gasket in the injection pump. This catalog is where those numbers live.
It is Yanmar's factory parts catalog, publication 0CW10-M83100EN, for the 3TNV80F-SPAMM diesel as supplied for the trench roller application. Twenty-one pages in English walk the engine system by system: cylinder block, gear housing, oil sump, cylinder head and bonnet, camshaft and driving gear, crankshaft and pistons, lube oil and cooling water systems, injection pump, governor, injection valves, fuel filter, starter, generator, and the complete gasket set.
Build the whole order before the block goes back together, then print the page you are working from and let it get dirty at the bench. The PDF is 0.83 MB, downloads immediately, and prints clean.

Yanmar 3TNV80F-SPAMM (Ammann Trench Roller) Common Problems This Manual Covers
Cranks but will not start
A 3TNV80F that spins over without lighting usually has fuel trouble first: a plugged element or air sneaking past a tired gasket. The Fuel Filter section lists the filter assembly, element, plug, and gaskets so the whole housing can be freshened in one order.
Manual Section: Fuel Filter p. 16Smoke and rough combustion from worn nozzles
Injector nozzles wear long before the bottom end does, and the first symptoms are smoke and uneven running. The Fuel Injection Valve section breaks each injection valve assembly down to nozzle, spring, washers, and gaskets.
Manual Section: Fuel Injection Valve p. 15Surging or unstable idle
Hunting at idle often comes down to fatigued governor springs or slop in the lever pins. The Governor section identifies the governor assembly, levers, springs, pins, and shaft as individual parts rather than one sealed unit.
Manual Section: Governor p. 14Overheating and belt failures
Water pump, thermostat, fan, and belt all live on one page here. The Cooling Water System section lists the V-belt as size A36.5, so a spare can be matched without pulling the old one off first.
Manual Section: Cooling Water System p. 12Low oil pressure at the gauge
Before condemning the bearings, the oil pump, strainer, filter, and pipes are the cheaper suspects. The Lub. Oil System section covers each of them along with the gaskets you will disturb getting there.
Manual Section: Lub. Oil System p. 11Starter drags or fails to engage
Brushes and the pinion drive are the usual wear points. The Starting Motor section lists the starter motor assembly along with pinion, drive housing, and brush parts, so a rebuild is an option instead of a whole new unit.
Manual Section: Starting Motor p. 17Bottom end wear at rebuild time
Piston assemblies, connecting rods, bearings, and crank pins are all itemized in the Crankshaft & Piston section, down to the M12x1.25 crankshaft bolts, so the full bottom-end order can be built from a single page.
Manual Section: Crankshaft & Piston p. 10Frequently Asked Questions
Which engine does this parts catalog cover?
It is Yanmar publication 0CW10-M83100EN for the 3TNV80F-SPAMM engine, the build supplied for trench roller applications. All 21 pages apply to this one engine model, running from the Cylinder Block section through the Gasket Set section.
Does it include torque specs or repair procedures?
No. This is a parts catalog: it identifies parts system by system so the order goes in complete and correct. For torque sequences, clearances, and valve lash you would pair it with a service manual; this book is for building the parts list.
Are injection pump and injector parts listed?
Yes. The Fuel Injection Pump section on page 13 lists the pump assembly with delivery valve, plunger, springs, and gaskets, and the Fuel Injection Valve section on page 15 breaks each injector down to nozzle, spring, washers, and gaskets. p. 13
Does it cover the charging and starting systems?
Yes. The Generator section lists the 12V-40A generator assembly with its bracket, pulley, and regulator, and the Starting Motor section covers the starter down to pinion, drive housing, and brushes. p. 18
