This 135209 piston ring is listed as a replacement application for CAT 3306 engines, specifically associated with CAT D6G 14G and D6D models. The part is referenced for the 4LF302 turbocharger configuration. Because no OEM reference numbers are provided in the input data, buyers must verify fitment against their specific engine serial number and turbo unit. Confirm the physical dimensions and gap size of the ring against your existing component or service manual before ordering. This aftermarket part is intended for repair shops and fleet maintenance teams requiring a verified replacement for this specific engine series.

Technical Notes

The 4LF302 turbocharger is a fixed-geometry unit, meaning it does not use variable turbine geometry or adjustable vanes. This design relies on a fixed nozzle ring to direct exhaust gas flow. For this piston ring replacement, verify the ring gap and outer diameter against your specific service manual. Ensure the ring material and cross-section match the original component to maintain proper sealing within the turbocharger assembly. Do not assume universal fitment across all 4LF302 variants; confirm the exact part number 135209 and engine application before installation.

Product FAQ

This part is referenced for CAT 3306 engines, including applications in CAT D6G 14G and D6D models. Verify your specific engine serial number and turbo configuration before ordering.

Consult the specific turbocharger service manual for the 4LF302 unit to confirm oil feed line restrictor requirements. The piston ring itself does not dictate restrictor size, but proper oil flow is critical for bearing life.

Ensure the oil return line maintains the correct downward slope as specified in the CAT 3306 service documentation. Improper drain angles can cause oil accumulation in the turbocharger, affecting the 4LF302 unit.
