Crankshaft damage occurred after a fender had been placed in the bow thruster of this WP12. Since it was difficult to repair on board, the engine was brought to our workshop. The engine has been completely overhauled and a new crankshaft has been installed.

A marine engine overhaul or overhaul involves a complete disassembly, inspection and rebuilding of the engine. The process usually includes the following steps:

• Disassembly: The engine is completely disassembled and all parts are inspected for wear and damage. Any parts that are worn or damaged will be replaced.
• Cleaning: All parts are cleaned and any rust or corrosion is removed.
• Inspection: Each part is carefully inspected to ensure it meets the manufacturer's specifications and is in good working order. Parts that do not meet these standards will be replaced.
• Reassembly: The engine is reassembled with all new or refurbished parts installed.
• Testing: The engine is tested to ensure that it is operating properly and that all systems are functioning properly.
• Finishing: The engine is painted and any stickers are applied.
• Commissioning: The motor is commissioned, with the motor running for several hours to detect any problems.

Overhauling a marine engine is a complex process that requires specialized knowledge and equipment. It is usually performed by a marine engine repair company that is experienced in overhauling marine engines and has the necessary tools and equipment.

The time frame for a marine engine overhaul can vary depending on the condition of the engine, the extent of necessary repairs and the availability of parts. It can take several weeks or even months.

It is very important to use the correct parts and equipment and the correct procedures to avoid problems later on. Therefore, it is recommended to use OEM (Original Equipment Manufacturer) parts. Since this is a Weichai WP12 marine engine, ABATO Motoren was able to carry out the overhaul perfectly. For more information about overhauling marine engines, please contact us.
