The Komatsu PC40FR-2 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 PC40FR-2 is a 4-ton class front-reduced mini excavator, the successor to the FR-1. Komatsu parts data cross-references it to the Yanmar 3TNE88 and Komatsu 3D88, confirming the 88 mm three-cylinder core.

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.
