INSTALLATION - DIESEL WARNING: The normal operating temperature of 1. Install the catalyst assembly. 2. Install the nuts to the down pipe (2). 3. Install mounting bolts (4) and (7). 4. Install exhaust onto the diesel particulate filter (5). 5. Connect downstream oxygen sensor connectors (4). 6. Connect exhaust temperature sensors (3). 7. Connect differential pressure ports (2). 8. Connect negative battery cable. INSPECTION WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY HIGH. THERE- CARE SHOULD BE TAKEN WHEN WORKING NEAR THE CATALYTIC CONVERTER. THE TEMPERATURE OF THE CONVERTER RISES TO A HIGH LEVEL AFTER A SHORT PERIOD OF ENGINE Check catalytic converter for a flow restriction. (Refer to 11 - EXHAUST SYSTEM - DIAGNOSIS AND TESTING) Visually inspect the catalytic converter element by using a borescope or equivalent. Remove oxygen sensor(s) and NOTE: Before replacing a catalytic converter, determine the root cause of failure. Most catalytic converter 11 - 10 EXHAUST SYSTEM LX |
