U 0 INTCAR ADJUSTMENTS AND REPAIRS The exhaust system must be free of leakage, binds, grounding and excessive vibration. Exhaust system vibration, ground ing, or binds are usually caused by: loose, broken or improperly aligned clamps or brackets; improper in stallation of the resonator inlet pipe flange on the exhaust manifold out let flange, or improperly connected resonator crossover pipes. Any of the aforementioned conditions may cause changes to the clearances of the exhaust system components Fig. 2. If any of these conditions exist, the clearance of the exhaust system components must be checked, ad justed and neutralized strain re lieved, or replaced to make cer tain the specified clearances are maintained. EXHAUST SYSTEM ALIGNMENT The exhaust system components and clearance specifications are shown in Figs. 1 and 2. Perform the following procedure to adjust and neutralize the exhaust system compo nents: 1. Raise the car. Loosen the re taining nuts securing the muffler out let pipe lower clamp brackets to the hinge bracket assemblies. Loosen the relaining nuts and bolts securing the upper clamp brackets to the lower clmp brackets. 2. Loosen the retaining nuts and bolts securing the resonator hinge brackets to the plate brackets. Loosen the resonator crossover pipe retain me: clamp. l. Check the assembled length of thc mounting studs in the exhaust manifolds. If necessary, disconnect the resonator inlet pipes, and turn the studs inward or outward to ob tain the specified length. 4. Tighten the retaining nuts at the right and left inlet pipe to manifold flanges, evenly and alternately, to obtain the specified distance from the bottoms of the inlet pipe flanges to the tips of the mounting studs. Progressively tighten the retaining nuts to the specified torque. 5. Adjust the resonator crossover pipes at their connection to obtain the specified distance at the con necting flanges of the resonator inlet pipes, and the specified clearances for the resonator inlet pipes and resonators. Torque the resonator crossover pipe clamp retaining nuts to specification; then torque the reso

Refer to Figs. 1 and 2 for views of the exhaust sys tem components and their clearance specifications. RESONATOR INLET PIPE REMOVAL 1. Raise the car. To remove the lefthand resonator inlet pipe, remove the transmission linkage splash shield. 2. Remove the retaining nuts se curing the inlet pipe to the exhaust manifold. Remove the bolts and nuts securing the resonator inlet pipe to the resonator inlet pipe extension; remove the resonator inlet pipe, and discard the mounting gasket. INSTALLATION 1. Clean the mounting surfaces of the exhaust manifold and the inlet pipes. Position the resonator inlet pipe flange on the studs of the ex haust manifold, and loosely install the retaining nuts. Position a new gasket between the flanges of the resonator inlet pipes, and loosely in stall the retaining nuts and bolts. 2. Tighten the inlet pipe to mani fold flange retaining nuts, equally and alternately, to obtain the spe cified distance from the bottom of the inlet pipe flanges to the tips of the mounting studs. Tighten the re taining nuts, equally and alternately to the specified torque. 3. Torque the resonator inlet pipe to resonator inlet extension pipe re taining bolts to specification. Check the resonator inlet pipe clearance. Adjust and neutralize the exhaust system, if necessary. If the left-hand resonator inlet pipe was removed, install the trans mission linkage splash shield. 4. Lower the car. RESONATOR REMOVAL 1. Raise the car at the rear under body side members. This will allow the rear suspension to hang down ward of its own weight to provide clearance for removal of the reso nator assembly. 2. Remove the retaining bolts se curing the resonator inlet pipe and gasket to the resonator inlet exten sion pipe. Discard the gasket. Re move the bolts securing the resonator outlet pipe and gasket to the muffler inlet extension pipe. Discard the gasket. 3. Remove the retaining clamp from the resonator crossover pipe. Remove the nuts securing the resona tor bracket to the plate. 4. Disconnect the crossover pipe, and remove the resonator and mount ing bracket as a unit. Remove the hinge-bracket assembly and insula tor from the resonator, and replace an damaged or worn parts. INSTALLATION 1. Clean the mounting surfaces of the crossover pipes, resonator inlet and outlet pipes, and the muffler inlet extension pipe. Install the in sulator and hinge-bracket assembly on the resonator flange and torque the mounting bolts to specification. 2. Position the retaining clamp on the crossover pipe. Install the reso nator in the car and connect the resonator crossover pipe. Install the plate brackets on the plate and torque the retaining nuts to specifica tion. 3. Position the resonator inlet ex tension pipe and gasket on the inlet pipe, and torque the retaining bolts and nuts to specification. Position the resonator outlet pipe and gasket on the muffler inlet extension pipe and torque the retaining bolts to specification. 4. Adjust the resonator crossover pipes at their connection to obtain the specified distance at the connecting flanges of the resonator in let pipes, and torque the retaining clamp nuts to specification. 5. Check the clearances of the ex haust system components. Adjust and neutralize the exhaust system, if necessary. 6. Lower the car. EXHAUST MUFFLER REMOVAL 1. Raise the car. Remove the bolts securing the resonator outlet exten sion pipe and gasket to the muffler inlet extension pipe. Discard the gasket. 2. Remove the retaining bolt se curing the outlet pipe lower clamp bracket to the hinge-bracket assem bly. Remove the outlet pipe retain ing clamp brackets and the muffler assembly as a unit. Remove the upper and lower clamp brackets. In spect the clamp brackets and hingebracket, and replace any damaged or worn parts. INSTALLATION 1. Clean the mounting flanges of the resonator outlet extension pipe and the muffler inlet extension pipe. Position the upper and lower clamp brackets on the muffler outlet pipe, and loosely install the retaining bolt and nut. 2. Position the muffler and clamp bracket on the hanger assembly. In stall the lower clamp bracket on the hinge-bracket assembly. Install and torque the clamp bracket retaining bolt and nut to specification. 3. Install a new gasket, muffler inlet pipe extension and retaining bolts on the resonator outlet extension pipe, and torque the retaining bolt and nut to specification. 4. Check the clearance of the resonator outlet extension pipe, muf fler inlet extension pipe and the muffler. Torque the outlet pipe lower clamp bracket retaining bolt and nut to specification. 5. Lower the car.
