BELT TENSION ADJUSTMENT Fan belt tension adjustment Check the conditions of belts on the engine. Examine the edge of the belt for cracks or fraying. Check the tension of the belt by pushing on it with your thumb for A.C. compressor belt and Alternator / Power A.C.

The belts should have deflection of 8 to 10 mm. If the belt tension is not proper, get it attended at the nearest Authorised service outlet. A.C.

The procedure for bleeding the system is as follows : a. Ensure that fluid level in clutch fluid container is upto maximum level. b. Remove dust cap from slave cylinder bleed screw and clean the screw thoroughly. Attach bleeding tube to bleed screw and place other end of tube in a clean glass jar containing sufficient clutch fluid to submerge tube end. c. Pump clutch pedal twice or thrice slowly throughout its stroke and by holding clutch pedal in depressed condition, loosen bleed screw on slave cylinder, Watch for air bubbles in glass jar. d. Retighten bleed screw on slave cylinder and repeat the process until air bubbles cease to appear at the end of tube in glass jar, allowing only fluid to flow. e. After completing bleeding operation, ensure that bleed screw on slave cylinder is fully tightened. Replace dust cap on the bleed screw. During bleeding process keep a watch on fluid level in container and top-up. BLEEDING CLUTCH SYSTEM Clutch Fluid Container Bleeding clutch slave cylinder Bleeding clutch slave cylinder 64 65
BELT TENSION ADJUSTMENT Cooling system : If engine overheating occurs, there could be a fault in the cooling system which may be on account of : 1. Less coolant in the system or dirt/ scale having accumulated inside coolant passages, especially in the radiator core. 2. Chocking of radiator passages due to foreign material or damages. 3. Defective/stuck thermostat. 4. Loose fan drive belt. 5. Coolant leakage from system. Always use genuine radiator cap of 1.0 kg/cm2 ( 14 psi ), if required to be replaced. A proper radiator cap firmly fitted maintains pressure in the cooling system. Prevention of rust formation : Use genuine co-branded premixed coolant in the cooling system to prevent rust formation and freezing of coolant inside the crankcase passages. Fill the engine coolant auxiliary tank upto ‘FULL’ mark. Changing of coolant in the cooling system : (At every 50000 km or 2 years whichever is earlier) a. Drain the cooling system and flush it with clean water. b. Pour the genuine co-branded coolant into the radiator until it is full. c. Start the engine. Top up the radiator with coolant. d. Fill the auxiliary tank upto ‘FULL’ mark. e. Ensure no leakage in the system. VEHICLE MAINTENANCE 66 Engine Coolant Auxiliary Tank VEHICLE MAINTENANCE Brake system The dual circuit service brake system operated through the tandem master cylinder is designed such that one circuit will continue to provide braking action if the other circuit fails. This vehicle is fitted with disc brakes at front and drum brakes at rear. Stopping the vehicle after loss of the brake fluid in one circuit will require more pedal pressure and pedal travel than normal. Also stopping distance will be longer. <strong>Service</strong> brakes are vacuum assisted. In case of failure of vacuum, the vehicle can still be stooped, however with a higher effort. Bleeding the brake system If the brake pedal becomes spongy, this may be due to air in the hydraulic brake system. Whenever any repair / overhaul or disconnecting of any brake pipe is done, or level of brake fluid has fallen so low that air has been drawn into master cylinder, it is necessary to bleed the system to remove the trapped air. Proceed as follows for bleeding the brake system : a. Clean all dirt from around the fluid container. Remove cap and topup fluid upto the maximum level. b. Remove dust cap at each bleed screw and clean the area around it. c. Attach the bleed tube to the front left calliper bleed screw and place the other end in a clean jar containing sufficient fluid to submerge the end of the tube. d. Pump the brake pedal 3-4 times slowly throughout its stroke and by holding the pedal depressed, loosen the bleed screw and watch for air bubbles in the glass jar. 67 Bleeding Screw - Front wheel cylinder Bleeding Screw - Rear wheel cylinder BRAKES
