When a Komatsu PC35MR-2-A needs an engine, the part that trips buyers up is not finding a 3D88 - it is knowing whether the machine takes the three-cylinder or the four-cylinder, and mechanical or electronic. We carry the range, and we check the plate before anything ships.
The Komatsu PC35MR-2-A is a build variant of the 3.5-ton class PC35MR-2 short tail-swing mini excavator. Komatsu produced this platform in a number of sub-variants - the -A, -B, -NA, -NB, -SA and -SB - and engine parts data lists the 3D88E-5 across the series. Confirm the exact suffix from your data plate.

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.
