WESPC 81558D Bearing Replacement Fits Per-kins Engines Main Bearing Set 0.4

The 81558D main bearing kit is specifically engineered for Perkins engines, with core compatibility for the Perkins 400 Series (such as 404D-22TA, 403D-17) and select models within the 1000 Series. It finds extensive application in small generator sets and equipment utilising corresponding Perkins engines, providing essential support for power transmission.

As a critical support component between the engine crankshaft and cylinder block, the 81558D bearing provides stable support for high-speed crankshaft rotation. It reduces radial runout during crankshaft operation, ensuring precise alignment between the piston connecting rod assembly and the crankshaft. During operation, it smoothly transmits combustion-generated power to the crankshaft output end while absorbing vibrations and impacts from crankshaft movement. When engine noise or power loss occurs due to bearing wear, the 81558D serves as an OEM-grade replacement, swiftly restoring engine power transmission efficiency and operational stability.
