Caterpillar Machines Powered By 3114, 3116, And 3126 EnginesDescription of Change: A new top piston ring with Chrome-Ceramic Surface (CCS) face material is now used in all 3114 and 3116 engines in Caterpillar machines. A similar new top piston ring with CCS face material is also used in 3126 engines in Caterpillar machines. Formerly, the 3100 machine engines with 1-Piece aluminum pistons used conventional chrome plated top piston rings. The higher horsepower 3100 machine engines with 2-Piece steel-crown pistons used plasma coated top piston rings.
The new top piston rings are manufactured with (CCS) technology. The piston ring surface has several layers of hard chromium plating. Each layer of the chromium plating has a network of very small micro-cracks. Ceramic material is embedded into the micro-cracks. This manufacturing process produces consistent properties over the entire coating depth and results in a significant improvement compared to conventional chrome or plasma faced piston rings.
Adaptable To: The new improved (CCS) top piston rings are adaptable to the engines in these machines in place of any of the former top piston rings as shown in the following chart. For 3114 machine engines, the new CCS top piston rings were effective with the following engine serial numbers: 2FG6078, 2ZF9691, and 97Z4406. For 3116 machine engines with 1-Piece pistons, the new CCS top piston rings were effective with the following engine serial numbers: 4TF39882, 98Z24774, and 1CK13752. For 3116 machine engines with 2-Piece pistons, the new CCS top piston rings were effective with the following engine serial numbers: 4TF43199, 98Z21372, 1CK13737, and 7TM1170. For 3126 machine engines, the new CCS top piston rings were effective at first production, except for the Challenger 55. The new (CCS) top piston rings were effective for the Challenger 55 beginning with engine serial number 55K1552.
