Reconditioning AE Pistons
Precision machining, approved welding procedures, and controlled finishing processes restore auxiliary engine pistons for reliable combustion performance, reduced wear, and long-term service reliability.
Before repair work begins, auxiliary engine pistons are thoroughly cleaned using grit blasting or ultrasonic and chemical processes. This preparation ensures that inspection results are dependable and that every subsequent step is based on a clear understanding of the component condition. Machining is carried out using CNC-controlled equipment to accurately restore ring groove geometry, skirt dimensions, and pin bore tolerances. Controlled finishing and dimensional verification ensure the piston is ready for assembly and return to service.
Dimensional measurements verify ring groove and pin bore wear before machining decisions are made.
Dye penetrant testing supports early crack detection and reliable repair assessment.
Controlled finishing restores critical dimensions and supports long-term operational reliability.

Reconditioning AE Cylinder Liners
Precision honing, approved reconditioning procedures, and controlled finishing processes restore auxiliary engine cylinder liners for reliable sealing, correct bore geometry, and long-term service performance.
Before repair work begins, auxiliary engine cylinder liners are thoroughly cleaned using grit blasting or ultrasonic and chemical processes. Bore diameter, ovality, taper, and surface condition are inspected to establish the correct repair scope before machining begins. Honing and machining operations are carried out using CNC-controlled equipment to restore bore geometry, roundness, and surface finish to the required specification. Final dimensional verification confirms the liner meets design tolerances before assembly and return to service.
Dimensional measurements verify bore wear, taper, and ovality before honing decisions are made.
Dye penetrant testing supports early crack detection and reliable repair assessment.
Final honing verification confirms bore geometry and surface finish before return to service.
Prepared for precision honing
Pre-boring and honing preparation focus on restoring bore roundness, taper control, and surface finish before final dimensional verification.
Prepared for calibration testing
