General information
1. On 954 and 1124 cc models, the exhaust system consists of two sections - the front pipe and a tailpipe. The front pipe is secured to the manifold by nuts and to the silencer by a clamping ring.
2. On 1360 cc models, the exhaust system consists of three sections - the front pipe, the intermediate pipe and silencer box and the tailpipe and main silencer box. All exhaust sections are joined by a flanged joint. The front pipe joints are secured by nuts and bolts, while the intermediate pipe joint is of the spring-loaded ball type, to allow for movement in the exhaust system. The intermediate pipe-to-tailpipe joint is secured by a clamping ring.
3. The system is suspended throughout its entire length by rubber mountings.
Removal
4. Each exhaust section can be removed individually; alternatively, the complete system can be removed as a unit.
5. To remove the system or a part of the system, first jack up the front or rear of the car and support it on axle stands (see "Jacking and vehicle support"). Alternatively, position the car over an inspection pit, or on car ramps.
Front pipe - 954 and 1124 cc models
6. Undo the nuts securing the front pipe flange joint to the manifold, then separate the flange joint and collect the gasket.
7. Slacken the front pipe-to-tailpipe clamping ring bolt, then disengage the clamp from the flange joint and manoeuvre the front pipe out from underneath the vehicle.
Front pipe - 1360 co models
8. Undo the nuts securing the front pipe to the manifold and the bolt securing the front pipe to its mounting bracket. Separate the front pipe from the manifold and collect the gasket.
9. Slacken and remove the two nuts securing the front pipe flange joint to the intermediate pipe and recover the spring cups and springs. Remove the bolts, then withdraw the front pipe from underneath the vehicle and recover the wire-mesh gasket.
Intermediate pipe -1360 cc models
10. Undo the two nuts securing the front pipe flange joint to the intermediate pipe. Recover the springs and spring cups and withdraw the bolts.
11. Slacken the intermediate pipe-to-tailpipe clamping ring bolts and disengage the clamp from the flange joint.
12. Free the intermediate pipe from its mounting rubbers, then withdraw it from underneath the vehicle and recover the wire mesh gasket from the front pipe joint.
Tailpipe
13. Slacken the intermediate pipe-to-tailpipe clamping ring bolt and disengage the clamp from the flange joint.
14. Unhook the tailpipe from its mounting rubbers and remove it from the vehicle.
Complete system
15. On 954 and 1124 cc models, disconnect the front pipe from the manifold as described in paragraph 6. On 1360 cc models, disconnect the front pipe from the manifold as described in paragraph 8.
16. On all models, with the aid of an assistant, free the system from all its mounting rubbers and manoeuvre it out from underneath the vehicle.
Heat shield
17. The heat shields (where fitted) are secured to the underside of the body by a mixture of nuts and bolts. Each shield can be removed once the relevant exhaust section has been removed. If the shield is being removed to gain access to a component located behind it, in some cases it may prove sufficient to remove the retaining nuts and/or bolts and simply lower the shield, without disturbing the exhaust system.
Refitting
18. Each section is refitted by a reverse of the removal sequence, noting the following points:
- a) Ensure that all traces of corrosion have been removed from the flanges and renew all necessary gaskets.
- b) Inspect the rubber mountings for signs of damage or deterioration and renew as necessary.
- c) On 1360 cc models, prior to assembling the front pipe-to-intermediate pipe joint, a smear of high-temperature grease should be applied to the joint mating surfaces.
- d) In the case of the front pipe/intermediate pipe-to-tailpipe joint, apply a smear of exhaust system jointing paste to the flange joint, to ensure a gas-tight seal. On 1360 cc models, tighten the clamping ring nuts evenly and progressively to the specified torque, so that the clearance between the clamp halves remains equal on either side.
- e) Prior to tightening the exhaust system fasteners, ensure that all rubber mountings are correctly located and that there is adequate clearance between the exhaust system and the vehicle underbody.
