This aftermarket replacement piston ring set, part number 04158805, is specifically designed for a wide range of Deutz-Fahr engines, offering a cost-effective alternative to original equipment manufacturer (OEM) parts. Engineered for engines with a 100mm bore, this set includes three precision-machined rings: two compression rings, each 2.5mm thick, and one oil control ring, 4mm thick. These rings are crucial components in an internal combustion engine, forming a vital seal between the piston and the cylinder wall to prevent combustion gases from escaping into the crankcase and to effectively control oil consumption. This compatible piston ring set is suitable for various Deutz engine series, including F3L912, F4L912, F6L912, F3L913, F4L913, F6L913, BF4L913, BF6L913, F4L914, F6L914, BF4L914, and BF6L914. Replacing worn piston rings is essential for maintaining optimal engine compression, reducing excessive oil consumption, and ensuring efficient engine performance. This non-OEM alternative provides reliable sealing and durability, helping to restore engine power and fuel efficiency without the premium cost associated with a genuine part. Ideal for routine maintenance, repairs, and engine overhauls, this replacement set ensures your Deutz-Fahr machinery continues to operate effectively and reliably.
