Technical Notes

The S2A turbocharger model is associated with industrial and off-highway applications, including Perkins Phaser 110T, Deutz BF4M1013E, and CAT 3116T engines. This piston ring is a critical wear component; inspect the old unit for scoring, debris, or foreign object damage (FOD) before installation. If FOD is present, clean the oil and coolant lines to protect the new 186842 part. Verify that the cooling port layout on your existing turbo matches the replacement part to ensure proper alignment with the engine's cooling system. Additionally, check the wastegate operating pressure setting for your specific engine application, as incorrect pressure can impact component longevity. Confirm these technical details against your service manual before ordering.
