Description

YANMAR GENERATORS AND POWER UNITS:
• Yanmar 4TNE106/4TNV106/4TNV106T 4TNE106/4TNV106 4.4L Diesel (2000-2025)

KOMATSU COMPACT EQUIPMENT:
• Komatsu 4D106 4D106 4.4L Diesel (2017-2025)


IMPORTANT:
Oil pump for Yanmar 4TNE106/4TNV106 — a 4.4L 4-cylinder diesel used in Yanmar generators, power units, and Komatsu compact equipment (sold as Komatsu 4D106). Alt number: 123900-32000. Helical gear type with 29-tooth drive gear.

The TNE suffix = indirect injection (older), TNV = direct injection (newer). Both use this same pump. This is one of the larger Yanmar industrials. Do NOT confuse with 4TNE/4TNV98 (3.3L) — different pump despite similar naming convention. Failure symptoms: declining pressure at hot idle, valve train noise, oil pressure light flickering. Inspect pickup screen for debris. On generators, low oil pressure triggers automatic shutdown — intermittent shutdowns at load are the primary complaint.

⚠️ Fits 4TNE106/4TNV106 (4.4L) only — NOT 4TNE/4TNV98 (3.3L).
