What We Do
Engine Reconditioning
Comprehensive
engine reconditioning services restore worn components to optimal condition using precision techniques and quality parts. Suitable for petrol, diesel, and industrial engines.
Engine Machining
High-accuracy
machining is carried out using modern equipment to meet manufacturer specifications on engines from single-cylinder motorbikes up to Caterpillar C175, Cummins QSK and Komatsu 12V140s.
Cylinder Blocks
Cylinder block services include boring, sleeving, and surface milling to ensure accurate sealing and performance. All blocks are cleaned, inspected, and machined to strict tolerances.
Crankshafts
Crankshaft grinding, polishing, and crack testing are performed to restore proper balance and journal integrity. Services accommodate a wide range of engine types and sizes.
Connecting Rod
Connecting rod resizing, bush replacement, and crack testing are completed with precision to maintain engine reliability. All rods are aligned and inspected before reassembly.
Cylinder Heads
Cylinder heads are reconditioned with crack testing, resurfacing, valve seat machining, and pressure testing. Each unit is restored to meet performance and durability standards.
Powertrain Component Repairs
Critical powertrain components such as gears, shafts, and housings are repaired or reconditioned to factory specifications. Work is carried out to maximise service life and reliability.
Metal Spray
Thermal metal spray is used to recreate worn surfaces on engine components with minimal distortion. This process improves durability and restores original dimensions.
