IMPORTANT:
Oil pump for JD 300-Series 6-cylinder engines (6.359D, 6.404D, 6.466D) — covers 5.9L through 7.6L displacements. Spur gear type with 2-bolt mount. Used in JD combines (2054-2258), tractors (6506-6900), and forage harvesters (5720/5820). All 300-Series 6-cylinder variants use this same pump.

The 300-Series was JD's workhorse diesel family from 1960s-1990s. These are mechanically injected — no electronic monitoring, so watch the oil pressure gauge. Failure symptoms: gradual pressure decline over service intervals, valve train tapping at hot idle, low pressure warning under load. Inspect drive gear mesh and pickup screen. Replace gasket during installation.

⚠️ Fits all 300-Series 6-cylinder (6.359/6.404/6.466) — NOT for 4-cylinder 300-Series.
