4 EXHAUSTSYSTEM-2.2LDICOR Maintenance of Closed Coupled Catalytic Converter (ccc) Closed Coupled Catalytic Converter should be flushed by giving full throttle (4 to 5 times) in standing condition of vehicle on daily basis. In addition to this it is recommended to run the vehicle at high speeds (80 to 100 kmph) for few km as this will help to flush the carbon soot deposits from exhaust system and ccc. High speed running of the vehicle may be done periodically to avoid chocking of ccc. Alternatively flushing operation for cleaning the catalytic converter can be done by dry compressed air draft (3 to 4 bars) directed on the honeycomb structure of catalytic converter (after removing from vehicle) Avoid : l Push start or tow starting the vehicle. (Use jump leads). l Long (not more than 10 seconds) repeat (not more than 3 times) starting of the vehicle. Investigate the cause for difficulty in starting and rectify the same. l Long idling (to warm-up). If the engine is running rough, after a cold start. l Switching “OFF” the ignition when driving down the hill. l Fuel tank getting almost empty. l Pre- Coating/Painting of Catalytic Converter. ParkingWarning : Avoid parking the vehicle over inflammable materials, such as dry leaves, grass, etc. as the exhaust system is hot enough to initiate “FIRE”. EXHAUSTPIPE(Front) For replacement of exhaust pipe, be sure to hoist vehicle and observeWARNINGunder “Maintenance”. Removal l Disconnect the front exhaust pipe at Close Coupled Catalytic Converter (ccc) end by removing the 3 bolts. l Similarly disconnect at pre-silencer end. l Remove the front exhaust pipe assly. Inspection l Check for damages l Check the condition of rubber hangers. Replace if required. Fitment l Guide the front ehaust pipe in rubber hanger. l Slightly tighten the mounting bolts at ccc end & at pre-silencer end. l Tighten the mounting bolts to specified torque. General Maintenance To avoid the danger of being burned, do not touch the exhaust systemwhen the system is hot. Any service on the exhaust system should be performed when the system is cool. At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust systemas follows : l Check rubber mount ings for damage, deterioration,and out of position. l Keep sufficient clearance between exhaust system components and underbody or adjust parts. l Check exhausts system for leakage, loose connection, dent and damage. l If bolts or nuts are loosened, tighten them to specified torque. l Check nearby body areas for damage, missing or mispositioned part, open seam, hole, loose connection or any other defect which could permit exhaust fumes to seep into vehicle. NOTE: l For disassembly and assembly of pre-silencer, main silencer and post silencer, lift the vehical on a lift. Refer the exploded view given in this section for the fitment details / sequence. l Tighten the mounting bolts & nuts to specified torque when re-assembling. l After installation start the engine and check each joint of exhaust system for leakages.
