Looking for a 3D88 for a Komatsu PC30MR-2? We hold this engine new surplus and rebuilt, and we build the core to match the mini excavator it is going into. Send the data plate and we will confirm which one you need.
The Komatsu PC30MR-2 is a 3-ton class short tail-swing mini excavator, heavily used in US residential, utility and landscaping work. Note that Komatsu built the PC30MR-2 with more than one engine across its run - both the 88 mm and the 84 mm three-cylinder appear in parts data - so the bore must be confirmed from the data plate.

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-5 / 3D84E. Production years: 2000-2008.

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.
