Left Crankcase For CF 500 X5 CF600-3 CF600-5

Support and protect the crankshaft
The left crankcase provides support for the crankshaft during installation and operation, while fixing the bearing and limiting its range of motion to ensure that the crankshaft can rotate smoothly within the specified space.
Sealing function
The left crankcase cooperates with the right crankcase and other seals to form a closed cavity to prevent lubricating oil leakage and prevent dust and other impurities from entering the interior and affecting engine performance.
Lubricating oil storage
The crankcase usually has the function of storing engine oil. The lubricating oil circulates inside to lubricate the crankshaft, connecting rod and other components to reduce friction and wear.
