🔧 Common Failure & Solution: CAT C27 Engine Crankshaft Issue

Problem: In a Caterpillar 988H Wheel Loader equipped with a C27 engine, excessive vibration and knocking noises were detected during operation. Diagnosis revealed crankshaft journal wear due to insufficient lubrication and prolonged overloading.

Solution: Replace the worn crankshaft with a high-quality replacement like Growshine’s 384-9907 / 3849907, flush the oil system, install a new oil filter, and ensure proper engine load management. Always use OEM-spec engine oil and perform regular maintenance to prevent recurrence.

Knowledge Corner: What Is a Crankshaft?

A crankshaft is a critical rotating component in internal combustion engines that converts the linear motion of pistons into rotational motion to drive the transmission and wheels or hydraulic systems. In heavy machinery like the CAT C27 engine, the crankshaft must withstand extreme torque and thermal stress. Precision balancing and high-grade steel are essential for longevity and performance.
