The John Deere 35D is a machine where the engine variant genuinely matters - some carry the mechanical 3TNV88, others the electronically governed 3TNV88F. We stock the 3TNV88 in both mechanical and common rail, new surplus and rebuilt, and we check the plate before anything ships.
The John Deere 35D is a 3.5-ton class compact excavator built on the Deere-Hitachi platform and sold across the United States. It is powered by the 3-cylinder Yanmar 88 mm-bore direct-injection diesel. Note that the later John Deere 35G uses the electronically governed 3TNV88F with EGR - a different engine from the mechanical 3TNV88.
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).

Engine as fitted to this machine: 3TNV88. Production years: 2007-2014. Rated output in this machine: approximately approx. 30 hp.
WHAT WE FIT TO YOUR MACHINE.
On a mini excavator the core engine is only half the job. The bellhousing and flywheel have to mate to your hydraulic pump drive, the oil pan has to clear the undercarriage, and the throttle has to answer to the machine's engine control. Those are all external parts and they carry across from the engine you are pulling out - we build the core to suit.
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.

GETTING IT RIGHT FIRST TIME.
We have supplied Yanmar TNV engines into US equipment for over five years, and every order gets cross-referenced against the machine's data plate before it ships. Send us the plate off your John Deere 35D and we will confirm the fuel system, tell you which accessories transfer, and quote you - mechanical or common rail, new surplus or rebuilt.
