IMPORTANT:
Direct Yanmar OEM pump for TNE/TNV 84/88 engines (3-cyl and 4-cyl variants). Same pump as JD AM878778. Covers 3TNE84 through 4TNV88 — all use this pump regardless of cylinder count or injection type.
Used in Hitachi mini excavators, JD compact equipment, Takeuchi, and Yanmar marine (3JH/4JH). Trochoid type. Failure: low hot idle pressure, gradual decline. Inspect pickup screen and housing bore.
⚠️ Fits all TNE/TNV 84/88 variants. Same as JD AM878778.
