Will Replacing Engine Bearings Have Any Impact?
1 Answers
Replacing engine bearings has no impact. Crankshaft: The crankshaft, along with the big and small bearings on the pistons. After an oil leak where there is no lubrication, the engine continues to operate, causing the crankshaft bearings to stick to the cylinder block, and the piston bearings to stick to the crankshaft. Function of the Crankshaft and Connecting Rod: The motion pair between the connecting rod and the crankshaft is a friction pair. The connecting rod and crankshaft are matched with bearing shells, lubricated by engine oil in between, with a clearance of only 0.03-0.05mm. Most crankshafts are made of ductile iron, with different grades having varying quenching hardness, generally ranging between HB130---240. The crankshaft receives the force transmitted by the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads.
