Overhaul

​          Disassemble all parts to inspect, replace worn parts, and reassemble them like a new engine. The main purpose is to restore the integrity and efficiency of the engine that has deteriorated from long-term use.
​
Reasons for engine overhaul
• The engine has a long service life. Internal engine parts such as pistons, piston rings, connecting rods, crankshafts, and other parts will wear out due to use, reducing efficiency. The engine is noisy, produces black smoke, and consumes more fuel.
• The engine is damaged by accidents, improper use, or improper maintenance, which may cause cracks in the engine block or internal parts to be damaged beyond repair.
