Cylinder Head Reconditioning Services
At Bodursan, we provide durable and cost-effective solutions for cylinder head repairs. Our reconditioning process ensures that each cylinder head is restored to the highest standards, offering long-lasting performance at a fraction of the cost of new replacement parts.
Upon receipt, the cylinder head undergoes a thorough cleaning and degreasing process. Each part is then tagged with a unique reference number for traceability. A detailed inspection report, including high-resolution photographs, is generated and sent to the customer for approval. The report contains an assessment of the damage and recommendations for repairs, along with a list of necessary spare parts.
Once approval is granted, the cylinder head is subjected to precision machining, with defective areas rebuilt using high-quality, machineable cast iron. This is followed by strict pre- and post-heat treatments to enhance the material’s strength and durability. After the heat treatment, the cylinder head is re-machined to meet the original specifications. New valve seats, guides, and other necessary components are fitted, ensuring the cylinder head is fully reconditioned and ready for installation.
Exhaust Valve Housing and Cages Reconditioning
Bodursan offers comprehensive reconditioning services for exhaust valve housings and cages, ensuring that every part meets original specifications for optimal performance. We follow strict welding procedures and heat treatment protocols to guarantee the highest quality reconditioned products.
The reconditioning process includes:
• Removal of damaged seats and passageways.
• Manufacture of new seats and stellite coating of the valve seating face for enhanced hardness and wear resistance.
• Cleaning and clearing of water-resistant passageways to ensure proper functionality.
• Precision machining of the seat and cage for a perfect fit, ensuring leak-free operation.
Each valve cage is meticulously reconditioned, including both cooled and non-cooled versions. We restore all components to their original specifications, whether it’s the upper or lower part of the valve cage. Once the reconditioning is complete, the finished product is painted, packaged, and dispatched, ready for installation.
Exhaust Valve Spindle and Seat Reconditioning
We provide complete reconditioning services for exhaust valve spindles and seats, ensuring that your exhaust valves are in perfect working condition. The reconditioning service includes the following steps:
• Cleaning and fault detection to identify surface defects.
• Premachining and build-up welding to restore the spindle and seat to their original shape.
• Final machining and dimension checks to ensure the parts meet exact specifications.
• Crack detection using advanced non-destructive testing methods.
• Stellite removal and replacement where necessary to ensure the valve seat surface is as hard as required for long-term performance.
• Plasma powder welding for stellite application to the valve seat for additional wear resistance.
For Nimonic-type valves, we use the WIG-cold-wire welding method for build-up welding, ensuring that all repairs meet the highest industry standards.
Connecting Rod Reconditioning
Bodursan offers high-quality reconditioning services for connecting rods of all types and makes. Our reconditioning process involves several key stages to ensure that connecting rods are restored to their optimal strength and performance:
• Cleaning and Disassembly: Each connecting rod is carefully disassembled, cleaned, and checked for any visible damage.
• Inspection for Damage: We thoroughly inspect the connecting rod for cracks, overheating, or any signs of wear that may compromise its performance.
• Ovality and Bore Inspection: We check for ovality in the big-end bore and any damage to the small-end bore.
• Re-machining and Re-boring: If necessary, we re-machine the connecting rod and re-bore the damaged sections, then fit new bushings, screws, bolts, and nuts.
• Final Checks: After reconditioning, the connecting rod undergoes rigorous dimension checks, ensuring that it meets the required specifications.
Upon completion, a detailed work report is provided to the customer, ensuring full transparency of the reconditioning process.
Piston Rod Reconditioning
At Bodursan, we offer top-tier piston rod reconditioning services. The process includes the following critical steps to restore the piston rods to their original specifications and ensure their long-term reliability:
• Inspection and Dimensional Reporting: Each piston rod is carefully inspected for defects, and a dimensional report is generated.
• Non-Destructive Testing (NDT): We use advanced NDT methods to detect any surface-breaking defects that may compromise the integrity of the piston rod.
• Weld Overlay Restoration: We restore any material loss using weld overlay techniques to rebuild worn areas.
• Customized Post-Weld Heat Treatment: After welding, we apply customized heat treatment processes to relieve stress and restore the material’s properties.
• Precision Grinding: After heat treatment, the piston rod is precision ground to meet the original specifications.
• O-Ring Groove Restoration: We also restore O-ring grooves, ensuring a perfect seal for reliable operation.
