Frequently Asked Questions (FAQ)
What is the function of a connecting rod bearing in a Volvo D8K engine?
In a Volvo D8K engine (and similarly in a D8F), the connecting rod bearings (like VOE21688936) sit between the connecting rod and the crankshaft journal. Their primary function is to provide a low-friction surface for the connecting rod to rotate on the crankshaft. They carry the combustion load transferred from the piston and rod to the crankshaft and must maintain a precise oil film to prevent metal-to-metal contact, ensuring smooth operation and preventing engine seizure.
When should connecting rod bearings be replaced on a Volvo D8F engine?
Connecting rod bearings on a Volvo D8F should typically be replaced during a major engine overhaul or rebuild. Replacement might also be necessary if symptoms like engine knocking noises (rod knock), low oil pressure, or metal particles found in the engine oil are present. Adhering to Volvo's recommended service intervals and using high-quality bearings like 04907575KZ / 04907579KZ / VOE21688936 is crucial for engine longevity.
Are these bearings (VOE21688936) compatible with engines other than Volvo D8K and D8F?
These specific bearings, identified by part numbers VOE21688936, 04907575KZ, and 04907579KZ, are designed explicitly for Volvo D8K and D8F engines. While Volvo may use similar bearings in other engine models, it is crucial to verify the exact part number required for your specific engine model and serial number using the official Volvo parts catalog or by consulting a qualified technician. Using incorrect bearings can lead to severe engine damage.
