CAUTION: Replacement of nuts and bolts: Various thread-locking devices are used on nuts and bolts throughout the vehicle. These devices restrict the number of times a nut or bolt can be used. Remove brake fluid spillage immediately from paint work, with clean water. 1. 2. 3. 4. 5. 6. 7. Position vehicle on a four-post lift. Move driver’s seat fully rearward. Open engine compartment and fit paint work protection covers to fenders. Disconnect battery ground cable. Remove engine compartment rear cover. Remove pedal housing, brake booster and master cylinder assembly. Remove reservoir filler cap and pour residual brake fluid into a container. Refit cap. 8. Remove the clevis pin connecting the brake pedal to the master cylinder push-rod fork. Remove grommets from access holes. Remove retaining clip. Remove clevis pin. 9. Reposition the brake pedal to access the nuts securing the brake booster to the pedal housing. Remove pivot pin nut. Remove pivot pin. Reposition brake pedal. 10. Remove brake booster from pedal housing. Remove grommet from access hole. Remove nuts.

CAUTION:Before removing spark plugs, check around each plug for debris that will fall into combustion chamber when plug is removed. 1. 2. 3. Remove three bolts securing cruise control actuator to A/C compressor and disconnect actuator wire harness connector. Disconnect vacuum hose from actuator and lay actuator aside. Remove ignition wires. 4. 5. 6. Remove vent hoses from distributor cap and remove cap. Loosen air pump belt adjusting bracket and remove belt from A/C compressor. Remove compressor mounting bolts, two front and two rear, and carefully lift compressor and move it forward slightly. It is not necessary to disconnect any freon hoses. This will give access to front two spark plugs. Before removing spark plugs, inspect around each plug and remove any debris that may fall into combustion chamber when spark plug is removed. Remove spark plugs. Be careful of vacuum advance unit. 7. 8. NOTE:Snap-On tool # FSX1220, works very well for plug removal. It is recommended that a compression test is performed when spark plugs are removed.

Remove the battery cover. Ensure that all electrical loads are switched OFF and that the engine is cool. Start the engine and allow to IDLE. Whilst the engine is idling, disconnect the battery negative terminal and, using a digital multimeter (DMM), measure the voltage between the terminal on the battery negative cable and the battery positive terminal. If the generator is working, the measured voltage should be within the range 13 V to 15 V. This indicates the system voltage without the battery in circuit. If the generator is inoperative, the engine will stall when the ground lead is disconnected. Repeat the test, using the ground bolt, as indicated (shown dotted on the illustration). There should be hardly any detectable difference in the voltage reading (due to minimal current flow); if there is a detectable difference, clean the cable terminal and the adjacent area of the body. When the voltage has been measured, STOP THE ENGINE. Reconnect the battery or fit a new battery if it was established that the battery was at fault. See: Battery/Service and Repair If the cooling fans operate during the above test, the large demand of current will overload the generator and cause the engine to stall. If the battery is in a low state of charge the voltage will rise momentarily when the battery is disconnected. However, the maximum that the voltage can increase to with this new generator is 25 V and then only for a maximum time of 200 mS.
