3406E Truck Engine Installation OR Removal Of The Speed/ Timing Sensor

1. Disconnect the speed/timing connector “P9/J9″ (2) . Inspect the connector for the following conditions. * Corrosion * Bent pins * Missing pins * Damaged sockets * Mismating * Broken wires 2. Remove the Speed/timing sensor (1) from the front gear cover. 3. Examine the plastic end of the sensor for signs of wear or contaminants such as metal filings. The plastic end of the speed/timing sensor should have no contaminants and should show no wear (greater than 0.051 mm (0.0020 inch) from the face) . 4. Use a screwdriver to carefully pry the plastic sensor end to the fully extended position (approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor). 5. Gently push in on the plastic end of the sensor. The plastic end should be firm. The plastic end should resist movement in the retract direction. If there is no resistance replace the sensor 6. Remove the two bolts (3) and remove the cover (5) from the flywheel housing. This hole is used for engine turning. 7. Put one bolt (3) in the timing bolt location (4) . The timing bolt location is approximately 127 mm to 152 mm (5 inch to 6 inch) above the hole in the flywheel housing for engine turning. I 8. Use 9S-9082 Engine Turning Tool (6) and a 1/2 inch drive ratchet wrench to turn the engine flywheel in the direction of normal engine rotation. The normal engine rotation is in a counterclockwise direction when viewed from the flywheel end. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: Visually check the location of the tooth on the wheel on which the speed/timing sensor is to be positioned. The end of the sensor must be in alignment with a tooth on the wheel and not in alignment with the valley of the wheel. Note: The No. 1 piston must be at either top center of the compression stroke or at top center of the exhaust stroke. 9. Inspect the speed/timing sensor before installation. Use steps 3 through step 6 to inspect the sensor. 10. If the sensor end is not fully extended, use a screwdriver to carefully pry the plastic sensor end to the fully EXTENDED position approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor.

1994 Chevy Truck C 1500 Truck 2WD Tune-up and Engine Performance Checks/ Ignition-Timing Connector Location Change Manual

SUBJECT: TIMING CONNECTOR LOCATION CHANGE MODELS: 1994 CHEVROLET AND GMC C/K TRUCKS WITH GASOLINE ENGINES The timing connector, which can be disconnected to return engine timing to base for adjustment purposes, has been moved from the engine compartment to inside the cab. This new location is not currently reflected in the Service or Owner’s Manual. The new location is under the dash directly below the glove compartment. The tan/black wire is routed for a short distance outside of a large wiring harness. This large harness is routed between the heater blower motor and evaporator case. The timing connector is taped to the wire bundle (Figure 1)

Rotary Fuel Pumps Timing to engine steps

SMALL | MEDIUM | LARGE Previous Next Fuel Injection Pump (Distributor Type) The fuel injection pumps, Bosch® VE, Lucas CAV DPA, Stanadyne DB4, Lucas CAV DPS, and Delphi DP210, are rotary distributor pumps. These pumps perform the four basic functions of: 1. Producing the high fuel pressure required for injection 2. Metering the exact amount of fuel for each injection cycle 3. Distributing the high-pressure, metered fuel to each cylinder at the precise time 4. Varying the timing relative to engine speed. SMALL | MEDIUM | LARGE Previous Next Distributor-Type Pump Governor Balance between the governor flyweights and control lever position controls the metering of the amount of fuel to be injected. The fuel injection pump governor performance and setting can affect engine power. Special equipment and qualified personnel are required to verify governor performance. If the seals are broken on the external Bosch® VE adjustment screw, the fuel rate can, perhaps, be out of adjustment The Lucas CAV DPA/DPS fuel injection pump uses a coded spring connection to change the governor setting. Incorrect connection of the governor spring can affect performance. Adjustments and rating changes are described in the Master Repair Manual, Injector Pumps and Injectors, Manual Shutdown Levers Both fuel injection pumps are equipped with mechanical shutdown levers. These levers are spring-loaded in the run position. Not all applications will use these manual shutdown controls and there will be no cable or rod connected to the lever. NOTE: Partial actuation of the mechanical shutdown levers will affect fuel flow and engine power. SMALL | MEDIUM | LARGE Previous Next Advance Timing Mechanism Regulated pressure produced by a vane supply pump in both fuel injection pumps is used to advance the timing as the engine speed increases. A return spring is used to retard the timing as the engine speed is reduced. If a spring breaks, the timing will go to the advance position, resulting in torque loss, fuel knock, and possible engine overheating. Retarded (late) timing will result in torque loss, high fuel consumption, and white to black smoke. SMALL | MEDIUM | LARGE Previous Next The Lucas CAV DPA/DPS advance timing mechanism uses a check ball in the circuit which, if omitted during assembly, will result in no timing advance. If the fuel injection pump has been replaced or the mechanism has been removed to fix a leak, the problem can be that the check ball is missing

2001 Honda Prelude Engine, Cooling and Exhaust Engine Timing Belt Service and Repair Manual

Removal and Installation REMOVAL NOTE: * Turn the crankshaft pulley so the No. 1 piston is at Top Dead Center (TDC) before removing the belt. * Inspect the water pump after removing the timing belt. * Replace the timing belt and timing balancer belt at 105,000 miles (168,000 km) according to the maintenance schedule (normal conditions/severe conditions). If the vehicle is regularly driven in one or more of the following conditions, replace the timing belt and timing balancer belt at 60,000 miles (U.S.A.) 100,000 km (Canada). * In very high temperatures (over 110°F, 43°C). * In very low temperatures (under -20°F, -29°C). 1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio’s preset buttons. 2. Disconnect the battery negative terminal first, then the positive terminal. 3. Remove the wheel well splash shield. 4. Loosen the adjusting bolt, locknut and mounting bolt, then remove the Power Steering (P/S) pump belt. 5. Remove the alternator terminal and connector. 6. Loosen the adjusting bolt, mounting bolt and lock nut, then remove the alternator belt. 7. Remove the side engine mount. NOTE: * Support the engine with a jack before removing the side engine mount and upper bracket assembly is removed. * Make sure to place a cushion between the oil pan and the jack 8. Remove the dipstick and the tube. 9. Remove the cylinder head cover. NOTE: The procedures in steps 10 and 11 are for reusing the timing belt. For replacing the timing belt, skip these procedures and go to step 12. 10. Use an open-end wrench to loosen the maintenance bolt. If it cannot be loosened with an open-end wrench, a box wrench can be used after removing the lock pin. NOTE: Use of a tool should be limited to initial loosening only 11. Unscrew the maintenance bolt by hand until it stops. The auto-tensioner bracket is now fixed. NOTE: * Never use a tool to unscrew the maintenance bolt after initial loosening it. * If the auto-tensioner has been extended and the timing belt cannot be installed, remove the auto-tensioner, compress it and reinstall it. 12. Remove the middle cover. NOTE: Do not use the middle cover to store removed items. 13. Remove the pulley bolt and crankshaft pulley
