IMPORTANT:
Oil pump GEAR SET (not complete pump) for Cat C3.3B — same engine as Kubota V3307. Includes spur gear drive components that install in the timing gear housing. If your housing is damaged, gears alone won't fix pressure. Inspect housing bore before installing.

Used in Cat 236D-289D skid steers, 299D compact track loaders, and TH-series telehandlers. The C3.3B/V3307 is a completely different engine from Cat C3.3 (Perkins 1103) despite similar naming — these gear sets are NOT interchangeable between the two engine families. Failure symptoms on skid steers: low hot idle pressure, intermittent shutdowns during aggressive operation. Before replacing gear set, verify with a mechanical gauge — electronic sending units on these machines give false low readings when wiring corrodes. Oil pressure port uses 1/8" BSPT threads.

⚠️ Gear set only. Fits C3.3B (Kubota V3307) — NOT Cat C3.3 (Perkins 1103).
