The Crankcase forms the main structural component of an engine, enclosing the crankshaft, pistons, and related rotating assemblies within the vehicle's engine bay. This critical part provides rigidity, supports the engine's internal components, and contains lubricating oil. Crankcases are typically constructed from cast aluminum alloys or cast iron for durability and heat dissipation. Variations exist to accommodate different engine sizes, configurations, and mounting requirements for passenger cars and commercial vehicles. Examples in our assortment include MAN crankcases with part numbers 51.01100-6741, 51.01100-6738, and 51.01100-6116. Precise fit and material integrity are crucial for optimal engine performance and longevity.
