FAQ

Q1: Is this a direct replacement for my Cummins K19 engine, or will I need to machine the crank?
A1: This is a direct replacement bearing set manufactured to “OEM Size.” It is designed for standard fitment. However, during any engine rebuild, it is critical to measure the crankshaft journals for wear and out-of-roundness. If the crank is within factory specifications, these bearings will fit perfectly. If the crank is worn, machining will be required, and you would need undersize bearings.

Q2: Does the set include both the upper and lower halves for all main and rod bearings?
A2: Yes, this is a complete set that includes all required bearing shells (upper and lower halves) for the main bearings (which support the crankshaft in the engine block) and the connecting rod bearings (which connect the rods to the crankshaft) for one Cummins K19 engine.

Q3: What is the lead time for shipping to [Europe/North America]?
A3: For standard container (LCL) sea freight, transit time to major West Coast US ports is approximately 18-24 days, and to North European ports like Rotterdam is 28-35 days. We also offer expedited air freight options, which can deliver to most global destinations within 5-7 business days. Exact lead times depend on the final destination and current shipping schedules.
