JKSSB Mechanic Detailed Syllabus
1. Basics of Vehicle Maintenance
Types of vehicle maintenance; preventive maintenance schedule; cost-effective repair decisions (repair vs replace); handling breakdowns during emergency duty; accountability for workmanship; coordination with stores, transport officers and inspectors.
Engine oil grades (10W-30, 15W-40 basics), gear oil & differential oil, brake fluid, coolant/antifreeze, grease types, proper disposal of used oil and waste. Belts and hoses inspection (serpentine, V-belts, coolant hoses); exhaust leaks and noise check; vehicle safety inspection (horn, seat belts, lights).
2. Driveline
Purpose of clutch, types of clutches, clutch components (clutch plate, pressure plate, linkage types); necessity of gearboxes, types, gearbox linkages, propeller shafts and types; drive axles, universal joints and constant velocity joints; final drive and differential; power transmission path to wheels; transaxle; basics of automatic transmission. Gearbox oil change (manual/automatic); clutch inspection and adjustment/replacement; drive shaft and CV joint inspection; differential oil change; transmission flush (automatic).
3. Running Gear
Physics of braking, working principle and construction of hydraulic braking system, disc and drum brakes, parking brake, ABS. Brake pad/shoe replacement; brake disc/drum inspection and resurfacing; brake fluid check and replacement; brake line/hoses inspection; caliper inspection and lubrication; ABS system check.
Manual and power steering, steering linkage types, steering gears; basic suspension types, effect on stability and control. Power steering fluid check and refill; steering linkage and tie rod inspection; shock absorber/strut replacement; suspension bush and spring inspection; wheel alignment and balancing.
Tyre construction, tyre size and markings, tyre condition and wear, load rating and retreading rules; tyre rotation and balancing; wheel alignment; tyre pressure check and inflation; tyre replacement and inspection for wear/damage.
Electrical & electronic systems — battery construction, working principle and construction of alternator and starter motor; battery inspection, cleaning and replacement; alternator and starter motor check; lighting system check (headlamps, indicators, brake lights); fuses and relays check; ECU and sensor diagnostics; wiring harness fault tracing; ECU fault codes (OBD).
4. Engine Servicing
IC engine terminology, engine classifications, main engine components, engine performance parameters; petrol and diesel engines (basic working); CNG, LPG systems (safety awareness); engine number identification; purpose of clutch, types of clutches, clutch operating mechanisms; need for gearbox, types of gearboxes (manual & automatic); final drive and differential, transaxles; power transmission path to wheels. Bharat Stage (BS) emission standards, catalytic converter, EGR, DPF, SCR (concept level), PUC relevance.
Engine Overhaul & Major Repairs: engine dismantling, inspection and reassembly; measurement of clearances (piston, bearing, valve); cylinder head servicing (valves, seats, guides); timing setting and calibration after overhaul. Spark plug replacement/glow plug check; timing belt/chain inspection and replacement; engine coolant/antifreeze replacement; throttle body cleaning; engine tune-up.
Radiator inspection and cleaning; coolant replacement; thermostat check; AC system service; heater core and blower inspection; fuel pump and injector cleaning; fuel line inspection; exhaust system inspection; emission system checks (O2 sensor, EGR valve).
Advanced Fuel & Injection Systems: diesel fuel injection systems (CRDI basics); injector testing, calibration principles; fuel pump timing and pressure checks; emission control devices (EGR, DPF — basic understanding); BS-VI norms (practical impact on maintenance); hybrid and electric vehicle basics; battery safety and high-voltage precautions.
5. Advanced Vehicle Diagnostics
Diagnostic scanners, digital multimeter, oscilloscope (automotive application), smoke machine, battery analyzer & charging system tester, pass-thru devices. Structure of OBD-II codes, generic vs manufacturer-specific codes, freeze frame & live data interpretation, pending vs confirmed faults, clearing codes vs fault rectification.
Engine Diagnostics (Petrol & Diesel): fuel system diagnosis, ignition system diagnosis, air intake & exhaust diagnostics, misfire detection, sensor rationality checks, emission system diagnostics.
JKSSB Mechanic Exam Preparation Strategy
The Mechanic syllabus goes a level deeper than Fitter, adding advanced vehicle diagnostics, OBD-II systems, and BS-VI/hybrid-EV basics. Candidates should build strong fundamentals in engine servicing and running gear first, then dedicate focused time to modern diagnostic tools and emission norms, as these represent the exam’s more technical, higher-difficulty portion.
