Description

CATERPILLAR EXCAVATORS:
• Caterpillar 320B/320C/320CL/320D 3066/S6K 6.4L Diesel (1996-2012)
• Caterpillar 321B/322B/322C 3066/S6K 6.4L Diesel (1996-2008)


IMPORTANT:
Oil cooler for the Cat 3066 engine, which is a Mitsubishi S6K under Cat branding. Fits Cat 320B/320C/320CL/320D and 321B/322B/322C excavators (1996-2012). Mitsubishi cross-reference: M34339-02102 — identical part, different OEM number. Order whichever number your parts supplier stocks.
Do NOT confuse with the Cat C6.6 engine oil cooler (B281-7039). The 3066/S6K and C6.6 are completely different engines despite both being Cat 6.4-6.6L 6-cylinders. The C6.6 is Perkins-based, the 3066 is Mitsubishi-based.
Failure symptoms: milky oil, oil sheen in coolant, elevated oil temps, unexplained coolant loss. Replace all gaskets and O-rings during installation.
⚠️ Confirm 3066/S6K engine — NOT C6.6 or 1106 series.
