| Pump Repairing - The scope of work for repairing the fuel injection pump (FIP) of 500 KVA Greaves-make Diesel engine involves a complete diagnostic, disassembly, overhaul and testing process to ensure the unit is fully operational and meets Greaves Cotton standards. The detailed scope of work is as under - (A) Pre-Repair Inspection and Diagnosis - • Initial Evaluation - Identify issues such as low fuel pressure, uneven engine speed (governor failure), excessive smoke or leaks. • Performance Testing - Run the engine to confirm the fault, checking for idle stability and response to load. • Fuel System Inspection - Check for air in the fuel system, restricted fuel lines and faulty fuel filters ensuring they are changed if necessary. (B) Disassembly and Cleaning - • Removal - Disconnect fuel lines, remove the injection pump coupling and extract the fuel injection pump unit carefully. • Cleaning - Clean the exterior and interior components using approved cleaning agents to remove sludge, rust and carbon deposits. • Inspection - Dismantle the pump to inspect for wear on internal components such as plungers, barrels, delivery valves and bearings. (C) Repair and Overhaul Scope - • Component Replacement - Replace defective parts with genuine Greaves-recommended components, including 'O' rings, gaskets, plungers and valves. • Governor Adjustment - Repair or adjust the speed governor assembly to ensure stable power output (especially critical for power car alternators). • Calibration - Calibrate the FIP on a test bench to ensure consistent fuel injection volume across all cylinders, preventing uneven running. • Water Pump Specifics - For water pumps, replace impellers, seals and bearings to stop leakage and restore circulation. (D) Assembly and Testing - • Reassembly - Reassemble the pump using new genuine gaskets and O-rings applying appropriate sealant. • Installation - Reinstall the pump on the engine and set the timing according to the manufacturer's specification. • Final Testing - Start the engine and test it under load to ensure - • No fuel/water leaks • Smooth idle speed • Optimal engine RPM • Optimal exhaust smoke levels (E) Consumables and Replacements - The following items are typically replaced during a pump repair: 1. Fuel Filter Element 2. Lube Oil (if contaminating the pump housing) 3. Gasket Sets and Seals 4. Fuel Pipes or Hoses (if damaged) 5. Pump Coupling | — | — | — | 1,93,520 | |
| Turbo Charger Repairing - The scope of work for repairing a turbocharger on a Greaves power car engine generally involves a complete overhaul, component replacement and high-speed balancing to restore optimal performance. The detailed scope of work is as under - (A) Preliminary Inspection and Dismantling - • Visual Inspection - Checking for external oil leaks, exhaust gas leaks, damaged housing, and loose connections. • Initial Testing - Checking for free rotation of the shaft and excessive shaft play (axial and radial). • Dismantling - Disassembling the turbocharger into its main components (turbine housing, compressor housing, and center housing/rotating assembly - CHRA). • Cleaning - Meticulous cleaning of all parts using specialized cleaning agents (sandblaster or ultrasonic cleaner) to remove carbon deposits. (B) Component Inspection and Testing - • Shaft and Wheels - Inspecting turbine wheel and compressor wheel for signs of rubbing, deformation, or foreign object damage. • Housing Check - Inspecting turbine/compressor housings for cracks, damage and wear. • Crack Detection - Performing NDT (Non-Destructive Testing) or Dye Penetrant Test on the shaft and turbine wheels to check for structural cracks. • Metrology - Measuring shaft journal diameters and housing bores to check for wear beyond service limits.
