2853671 REAR COVER ( GENUINE )

The 2853671 Rear Cover is a CNH Genuine engine component designed for multiple Case backhoe loader models, including 580 M Series 2, 580 Super M2, 580 M Series 3, 580 Super M3, and 580 N.

This rear cover mounts on the back section of the engine cylinder block, sealing and protecting critical engine components such as the crankshaft rear area, oil passages, and internal timing elements (depending on model design).

A high-quality rear cover is essential to maintain proper sealing, oil retention, structural support, and long-term engine reliability.

Function of the Rear Cover

The rear cover plays several important functions:

• Seals the rear section of the cylinder block

• Prevents engine oil leakage from the crankshaft and rear block area

• Houses sealing points for the rear main seal (in some configurations)

• Provides structural support to the engine block assembly

• Protects internal components from dust, dirt, and contaminants

• Helps maintain correct internal oil pressure pathways

It is a critical engine housing part affecting both sealing and mechanical stability.
