Steps in Engine Overhaul

Step 1: Initial Assessment

The diesel engine overhaul starts with our team's initial assessment, allowing us to create a targeted plan addressing specific concerns and optimizing resources for an efficient process.

Step 3 :Cleaning and inspection:

With the marine engine disassembled, our team cleans all parts, revealing hidden issues, gauging wear, detecting corrosion, and identifying potential damage not visible externally. This process helps prevent premature failures.

Step 5: Assembly

The engine is reassembled with precision, ensuring all parts fit and function correctly.

Step 7: Quality Assurance

Finally, quality control checks ensure the overhauled marine diesel engine meets quality norms before delivery. This quality assurance process reaffirms our commitment to providing customers with a thoroughly renewed engine that matches expectations.

Step 2: Disassembly

Following the initial ship engine assessment, our technicians systematically disassemble the entire unit for visual inspection, accurately pinpointing worn or damaged parts. Detailed documentation ensures streamlined reassembly later.

Step 4: Component Refurbishment: Assembly

Post-inspection, we refurbish or replace worn engine components, restoring them to optimal condition. This enhances the marine diesel engine's overall reliability and efficiency post-overhaul.

Step 6: Testing and Calibration

Operational and load testing under variable marine conditions allows our technicians to calibrate and fine-tune the overhauled diesel engine to meet efficiency . The engine testing processes validate the intended engine performance post-overhaul.
