Restoring a Damaged MAN Marine Engine Housing
Marine Engine Housing Repair
We revisit a marine engine repair project that showcases the true strength and precision of our proprietary Brush Plating Technology.
The job involved the complete restoration of a MAN Marine Diesel Engine Housing, which had suffered severe internal wear. The engine block’s main bearing bores and landing faces were badly scored and corroded, with deep pitting visible across multiple surfaces — a condition that would have otherwise rendered the entire block unusable or required full replacement.
🔍 Damage Overview:
- Scorelines on the main bearing saddles
- Corrosion pitting across the landing faces
- Wear on both internal bores and cap surfaces

🛠️ Our Solution: Brush Plating Precision Restoration
Using our in-house developed Brush Copper Plating technique, we:
- Rebuilt the bearing bores and landing faces to restore material thickness
- Ensured uniform copper deposition, localized to the damaged areas
- Allowed for the customer to perform final line boring, ensuring accurate alignment
- Finished the process with a Nickel Cap layer, sealing the repair and delivering a brand-new appearance with enhanced surface durability
The result? A fully restored engine block, saving the customer from costly component replacement, long lead times, and extended vessel downtime.
