Engine
- Our Engine Major Overhaul service is designed to restore your engine’s metrics, reliability, and efficiency—helping you avoid costly downtime and extend equipment life.
- We begin with complete disassembly and chemical cleaning of the engine. All components are carefully inspected and measured to identify wear or damage. Key parts such as cylinder heads, blocks, crankshafts, and pistons are reconditioned or replaced according to OEM specifications.
- The overhaul includes installation of new gaskets, seals, bearings, piston rings, and liners. Fuel and oil systems are flushed and restored, and all components are precisely reassembled and calibrated. Each engine is thoroughly tested for compression, oil pressure, and load efficiency.
- Engines are then painted, labeled, and prepared for delivery—ready to go back to work with dependable bechmark.

Transmission and Torque Convertor
Transmissions and torque converters play a critical role in powertrain empowered— transmissions manage gear shifting and power delivery, while torque converters transfer engine power to the transmission with smooth acceleration.
Our repair process includes complete disassembly, chemical cleaning, and inspection of all components. Worn gears, clutches, valve bodies, and bearings are reconditioned or replaced to OEM specs. Torque converters are rebuilt with new internal parts, balanced, and tested for efficiency.

Hydraulic Control Valves
Hydraulic Component Services can
rebuild or supply new industrial and mobile valves.
We can
provide complete valve rebuilding and reconditioning at substantial
savings. In our process, valves are completely disassembled, chemically
cleaned, and inspected. Worn bodies are precision honed for cleanup and
straightness. Pitted and worn spools are pre-ground, chrome plated,
finish ground, and are refit back into the valve body to proper
tolerances.
All check valves, cylinder port reliefs and the
main relief are inspected, reseated, and reset to manufacturer’s
specifications. All seals are replaced, and the valve is pressure oil
tested. Internal leakage is measured in cubic inch leakage per minute
and back pressured for external leakage. The valve body is fitted with
cap plugs and painted.
