Technical Advice: Before installing oversize bearings, it is mandatory to check the crankshaft journal dimensions with a micrometer after grinding. Ensure absolute cleanliness – even the smallest particle under the bearing can cause improper seating and engine seizure. During assembly, generously lubricate the working surfaces with clean engine oil or a specialized assembly paste. Always tighten the connecting rod and main bearing caps with a torque wrench according to the sequence and torque specified in the service manual.
