The Komatsu SK820-5 left the factory with the 3D88E-6. That is a Komatsu-badged Yanmar 88 mm three-cylinder, and we stock it - new surplus and rebuilt, in both fuel systems.
The Komatsu SK820-5 is a 3-ton class compact skid steer loader, the largest in Komatsu's SK line, running a 0.4 cubic metre bucket with around 1,867 daN of breakout force and joystick control of all functions. Komatsu parts data lists the 3D88E-6 in SK820-5E0 applications. CYLINDER COUNT WARNING: LECTURA also documents the SK820-5 with the four-cylinder S4D84E-6BMFD, so this platform genuinely spans both. Confirm from the data plate before you order.

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-bad
