Piston Ring Kit 863864 Bobcat Deutz 04179447

The Piston Ring Kit 863864 for Bobcat, manufactured to Deutz specifications, is a high-precision engine component designed for Deutz BF4M1011 and BF4M1011F diesel engines. This piston ring set is engineered to meet the exact mechanical and thermal requirements of heavy-duty industrial and construction applications where engine reliability is non-negotiable. Produced according to German engineering standards, this piston ring kit ensures optimal compression sealing, oil control, and heat transfer between the piston and cylinder wall. With a standard bore size of 91 mm, the kit is designed for direct installation without modification, making it suitable for standard overhaul and maintenance operations. The ring configuration 3 mm × 2 mm × 3 mm (compression ring / scraper ring / oil control ring) provides a balanced sealing system. The upper compression rings are designed to withstand high combustion pressures while maintaining stable compression ratios. The oil control ring effectively regulates oil film thickness, minimizing oil consumption and reducing emissions while protecting the cylinder liner from excessive wear. This piston ring kit is specifically matched to Deutz BF4M1011 series engines, widely used in Bobcat machines and industrial power units. Materials and surface finishes are selected to perform reliably under high load, elevated temperatures, and continuous operating cycles typical of construction and industrial environments.
