Component Reconditioning

Honing of Engine Components, Compressors, and Hydraulic Cylinders

Honing is critical to restoring the function and performance of marine engine components. Every part undergoes a rigorous process:

• Cylinder Liners: Checked for cracks (especially at the flange), machined as required, then honed to restore surface roughness (Ra, Rz) and crosshatch angle.
• Honing Equipment: We operate three dedicated honing machines to suit various liner sizes.
• Measurement Protocol: Post-honing, detailed measurement records are generated for quality assurance.
• Restoring Components to Manufacturer Standards
• Pistons: We inspect ring grooves, check shoulder play, and re-machine where necessary.
• Cylinder Heads: Fully disassembled on-site; valves, seats, and guides are measured and reconditioned using Chris-Marine and Hunger equipment. Valve seating surfaces are crack-tested and pressure-tested (10 bar at 60 °C). Valve guides are replaced using an in-house hydraulic press.
• Connecting Rods: Inspected for cracks and wear. Serrations and bores are restored or rebuilt as needed. Wärtsilä 20 and 32 rods with cross-cut serrations are skimmed. Damaged small-end bushes are replaced using cryogenic (liquid nitrogen) shrink-fit methods. Big-end bolts are replaced as standard.
• Testing • Reconditioning • Precision Repairs: From initial inspection to final pressure testing, our focus remains on delivering OEM-standard quality with every reconditioned component.
