Disassembly (Throttle Body Cover - Model 220)
- Place throttle body on Holding Fixture (J-9789-118 or BT-30-15) to prevent damage to throttle valve. Remove cover-to-throttle body screws (note location of 2 short screws). Remove throttle body cover. see scheme 3 Throttle body cover and pressure regulator are serviced as an assembly. DO NOT remove pressure regulator-to-cover screws.
- Remove TP sensor, IAC, fuel injector, fuel filter, rubber parts, and diaphragms. Clean all remaining (metal) parts in a cold immersion-type cleaner such as Carbon X (X-55). Blow dry with compressed air. Inspect mating surfaces for damage which may prevent gasket sealing. Repair or replace faulty components.
Disassembly (Fuel Meter Assembly - Model 700)
- Remove fuel meter-to-throttle body retaining screws. Remove fuel meter assembly. see scheme 3 Discard gasket. If fuel pressure regulator cover is removed, regulator diaphragm must be replaced to prevent fuel leaks.
- Remove TP sensor, IAC, pressure regulator assembly, fuel injector, fuel filter, rubber parts, and diaphragms. Clean all remaining (metal) parts in a cold immersion-type cleaner such as Carbon X (X-55). Blow dry with compressed air. Inspect mating surfaces for damage which may prevent gasket sealing. Repair or replace faulty components.
Reassembly (Throttle Body Cover - Model 220)
- Install NEW dust seal into recess of throttle body. Install fuel outlet passage gasket on cover. Install throttle body cover gasket on throttle body. Install cover, making sure pressure regulator dust seal and cover gaskets are in place.
- Apply thread locking compound to cover attaching screws. Install cover screws and lock washers. Tighten screws. Connect electrical lead to fuel injector, and install air cleaner.
Reassembly (Fuel Meter Assembly - Model 700)
- Install NEW fuel meter-to-throttle body assembly gasket. Match cutout portions of gasket with openings in throttle body assembly.
- Place fuel meter assembly on throttle body. Install fuel meter-to-throttle body retaining screws and washers (screws should be coated with locking compound). Tighten screws to specification. See «TORQUE SPECIFICATIONS»(ref-19437-S09934004602001010200000) .
- Install NEW "O" rings on fuel lines. Using a back-up wrench on fuel fittings, tighten fuel line nuts to 20 ft. lbs. (27 N.m). To complete reassembly, reverse disassembly procedure.
UPPER INTAKE MANIFOLD & CPI ASSEMBLY
Note. Identification number is stamped on base of upper intake manifold or on fuel pressure regulator. Identification number must be used for ordering replacement components.
Disassembly & Reassembly
- Disassembly procedure is not available from manufacturer. (Scheme 10)- (Scheme 13) for exploded views of distributors.
- When reassembling, ensure pick-up assembly arm is correctly installed on pin. If not, arm can float and cause ignition timing to vary. To prevent corrosion, lubricate terminals with petroleum jelly before installation.
- To prevent heat damage, coat bottom of module and module rest pad in distributor housing with silicone grease. Before installing roll pin in driven gear, ensure timing mark on roll pin and rotor tip align. (Scheme 10)- (Scheme 13).
