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.

Rated output in this machine: approximately approx. 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.
