Piston Rods

2-stroke engine piston rods can wear out in time or they can have scratches. These result in an increase in oil consumption because the stuffing box seals can not seal the oil properly. This will create a problem by means of oil pressure and consumption.
The reconditioning method of piston rods is very critical because it requires a lot of quality. Matra offers reconditioning by submerged arc welding (for better bonding compared to thermal spraying and hard chrome plating) or by laser cladding. Both of these methods should be premachined and then grinded for a better surface finish. For the lifetime of the stuffing box seal rings, the surface roughness should be very fine.
