Looking for a 3TNV88 for a Wacker Neuson 2702RD? We hold this engine in mechanical and in common rail, new surplus and rebuilt, and we build the core to match the tracked dumper it is going into. Send the data plate and we will confirm which one you need.
The Wacker Neuson 2702RD is a rubber-tracked dumper used in site preparation, landscaping and restricted-access material handling. It is powered by the Yanmar 88 mm-bore 3-cylinder. Tracked dumpers place a sustained load on the engine at working rpm, so a correctly specified variable-speed mobile engine - not a fixed-speed gen-drive unit - is essential.
ENGINE SPECIFICATION. Three cylinder, four cycle, liquid cooled, vertical in-line. Direct injection, naturally aspirated. Bore and stroke 88 x 90 mm. Displacement 1.642 L (100.2 cu in). Around 36 hp at 3000 rpm at full speed, less in machines governed lower. Dry weight approximately 341 lb (154 kg). Rotation counterclockwise viewed from the flywheel end. Engine as fitted to this machine: 3TNE88 / 3TNV88. Production years: 2005-2015. Rated output in this machine: approximately approx. 36 hp.
WHAT WE FIT TO YOUR MACHINE.
On a tracked dumper the engine works at sustained rpm under continuous load, with the hydraulic drive taken straight off the flywheel end. Bellhousing, pump drive, oil pan and cooling package are external and carry over from your old engine.
MECHANICAL OR COMMON RAIL - THIS IS THE ONE THING YOU MUST MATCH.
The Yanmar 3TNV88 comes in two fuel systems and they are not interchangeable. MECHANICAL INJECTION uses a mechanical pump and governor, with no ECU or sensors - this is what most machines in the field run, and it is our standard stock. ELECTRONIC COMMON RAIL (HPCR) is ECU-controlled, fitted to machines built to the later emissions standards. We carry both, in new surplus and rebuilt.
The suffix on your data plate - codes like -BKMS, -BPTB2, -QTB - does not mean a different engine. The core is the same across the family: same block, same crank, same 88 x 90 mm bore and stroke, same 1.642 L. The suffix tells you the fuel system and the accessory package. The accessories are external and swap; the fuel system is what has to match.
Two other variants to know about: the 3TNV88F has an ELECTRONIC GOVERNOR with EGR and is a different engine again, and the 3TNV88-GGE is a fixed-speed GENERATOR engine, not a machine engine. There is also a 4-CYLINDER 4TNV88 that is not the same as this three-cylinder engine at all.

BEFORE YOU ORDER.
Send the data plate off your Wacker Neuson 2702RD - model number, suffix, serial. We will confirm whether you need mechanical or common rail, check the cylinder count, tell you what bolts across from the engine you are removing, and quote you on the correct core. New surplus and rebuilt both available.
