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.

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.
