Injection Pump: Installation
- Install injection pump on front and rear brackets. Install pump sprocket and tighten retaining nut to 51-58 ft. lbs. (70-80 N.m). Install and tighten fuel lines.
- Install throttle and speed control cables, vacuum hoses, and fuel cut-off solenoid connector. Ensure engine is on TDC compression stroke on No. 1 cylinder.
- Install timing belt. Align timing marks on pump and camshaft sprockets. See Figure . Tighten tensioner lock nut to 15-20 ft. lbs. (20-27 N.m).
- Timing belt tension should be 22-33 lbs. (10-15 kg) measured on side opposite tensioner. Rotate engine 2 revolutions and recheck belt tension. Install timing belt cover and timing mark cover.
- Install air inlet duct. Connect battery cable. Bleed air from fuel system by loosening fuel line at No. 1 injector. Crank engine until a solid stream of fuel flows from the connection. Repeat for each injector.
- Check and adjust injection pump timing. See Adjustments. Run engine and check for fuel leaks. Adjust engine idle.
