We sell every version of the Komatsu 3D88 - mechanical and electronic, new surplus and rebuilt - and we build each one to the machine it is going into. We also supply the Yanmar 3TNV88, which is the same engine. This page explains the difference between the variants so you order the right one first time. If you already know what you need, send us your data plate and we will quote you. KOMATSU 3D88 AND YANMAR 3TNV88 ARE THE SAME ENGINE. Komatsu's small D-series diesels are Yanmar TNV engines built under the long-standing Komatsu-Yanmar relationship and badged as Komatsu. The Komatsu 3D88 / 3D88E is the Yanmar 3TNV88: same block, same crankshaft, same 88 x 90 mm bore and stroke, same 1.642 L displacement, same architecture. If your data plate reads 3D88E-3, 3D88E-5, 3D88E-6 or 3D88E-7, that is a Komatsu-badged Yanmar 88 mm three-cylinder. In practice this doubles the pool of engines that can be built to fit your Komatsu, and we supply from both. THE ONLY DIFFERENCE THAT REALLY MATTERS: HOW THE ENGINE METERS FUEL. Buyers usually start by hunting for the exact suffix that matches their machine. That is the wrong starting point. What actually has to match is the fuel system. MECHANICAL INJECTION. A mechanical injection pump with a mechanical governor. No ECU, no sensors, no wiring harness to match. This is what most machines in the field are running and it is our standard stock. ELECTRONIC / COMMON RAIL. ECU-controlled. Fitted to machines built to the later emissions standards -

We carry the full range of Komatsu 3D88 engines for the PC30MR-3 - new surplus and rebuilt, mechanical and electronic - and we build each core to the configuration your mini excavator needs. The Komatsu PC30MR-3 is a 3-ton class short tail-swing mini excavator, one of the most widely used Komatsu compacts on US utility, residential and urban jobsites. Its short rear overhang lets it work hard against walls and in trench lines where a conventional tail cannot turn. The MR-3 series is documented with the 3D88E-6 in Komatsu engine parts data and in the overhaul-kit fitment used across the trade. ENGINE SPECIFICATION. Three cylinder, four cycle, water 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 full rated speed, less in machines governed lower. Dry weight approximately 341 lb (154 kg). Engine as fitted to this machine: Komatsu 3D88E-6. Production years: 2008-2015. Rated output in this machine: approximately approx. 24-28 hp. KOMATSU 3D88 AND YANMAR 3TNV88 ARE THE SAME ENGINE. Komatsu's small D-series diesels are Yanmar TNV engines built under the long-standing Komatsu-Yanmar relationship and badged as Komatsu. The Komatsu 3D88 / 3D88E is the Yanmar 3TNV88: same block, same crankshaft, same 88 x 90 mm bore and stroke, same 1.642 L displacement, same architecture. If your data plate reads 3D88E-3, 3D88E-5, 3D88E-6 or 3D88E-7, that is a Komatsu-badged Yanmar 88 mm three-cylinder. This matters commercially because it doubles the pool of engines that can be built to fit your machine. We supply both, and we set the core up with the accessories your Komatsu needs. MECHANICAL OR ELECTRONIC - THIS IS THE ONE THING YOU MUST MATCH. The Komatsu 3D88 spans two fuel systems and they are not interchangeable. MECHANICAL INJECTION uses a mechanical pump and governor - no ECU, no sensors, no wiring harness to match. This is what most machines in the field run and it is our standard stock. ELECTRONIC / COMMON RAIL is ECU-controlled, fitted to machines built to the later emissions standards. We carry both, new surplus and rebuilt. The suffix - 3D88E-3, -5, -6, -7 - does not mean a completely different engine. The core is the same across the family. The suffix tells you the emissions tier, the fuel system, and the accessory package Komatsu specified for that machine. The accessory package is the part that can be changed: the bellhousing, flywheel, oil pan and sump, manifolds, alternator and starter position, pulleys, brackets, PTO and hydraulic pump drive and the throttle linkage are all EXTERNAL components. They bolt on and off, and they carry across from the engine you are removing onto the replacement core. So the working rule is: MATCH THE FUEL SYSTEM, ADAPT THE EXTERNALS. CYLINDER COUNT. The 3D88 is a THREE-cylinder engine, 1.642 L. The 4D88 / 4D88E is a FOUR-cylinder engine, 2.190 L. Same 88 in the name, different engine. Several PC40, PC45, PC50 and PC55-class machines run the four-cylinder 4D88E, not the three-cylinder 3D88E. Read the data plate - do not go by the machine model alone. TALK TO US FIRST. The fastest way to get the right engine for a Komatsu PC30MR-3 is to send us the data plate and tell us the machine. We confirm cylinder count and fuel system, set the core up with the accessories your machine needs, and quote you - new surplus or rebuilt, and we can supply the equivalent Yanmar 3TNV88 core as well.

The Komatsu PC35MR-3 is a mini excavator built around the 88 mm three-cylinder. We sell that engine new surplus and rebuilt, with the bellhousing, pump drive and pan set up for your machine. The Komatsu PC35MR-3 is a 3.5-ton class short tail-swing mini excavator and the successor to the PC35MR-2 in the US market. It is one of the highest-demand Komatsu compact platforms for engine replacement in the United States - a very large installed base, and machines that are now well into their second and third owners.

This is a direct 3D88 machine - the Komatsu PC35R-8 was built around this engine. We sell it new surplus and rebuilt, configured to your mini excavator, and we can supply the equivalent Yanmar 3TNV88 core as well. The Komatsu PC35R-8 is a 3.5-ton class mini excavator from Komatsu's R-8 compact series. Machines of this generation are mechanical-injection - no ECU, no sensors - which makes them straightforward to repower. A large number of PC35R-8 machines are still working in US rental and contractor fleets and are prime candidates for a replacement core rather than a full rebuild. ENGINE SPECIFICATION. Three cylinder, four cycle, water 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 full rated speed, less in machines governed lower. Dry weight approximately 341 lb (154 kg). Engine as fitted to this machine: Komatsu 3D88E-3. Production years: 1999-2005.
