The K 31669 Genuine Con Rod Bush is a precision-engineered engine component designed for CASE 580 F and CASE 580 G backhoe loaders. This connecting rod bush is installed between the connecting rod and piston pin, serving as a critical wear surface that ensures smooth rotation, proper lubrication, and accurate alignment during engine operation.
Manufactured to CNH Original (Genuine) specifications, this con rod bush is produced using high-strength, wear-resistant alloy materials to withstand high temperatures, heavy loads, and continuous engine stress. It plays an essential role in reducing friction, preventing metal-to-metal contact, and extending the service life of the connecting rod, piston, and crankshaft assembly.
The K 31669 Con Rod Bush is recommended during:
Engine overhaul or rebuild
Connecting rod servicing
Piston and piston pin replacement
Crankshaft and bearing system repair
Using genuine CNH parts ensures correct oil clearance, longer engine life, and reliable performance, especially under heavy-duty construction and earthmoving conditions.
