Installation Notes
Installation steps (overview for mechanical injection pump):
Disconnect battery negative cable – Safety first.
Relieve fuel system pressure – Loosen fuel lines carefully.
Remove old injection pump – Disconnect fuel lines, electrical connectors (stop solenoid), and mounting bolts. Remove drive gear or coupling carefully, noting timing marks.
Compare new pump with old – Check drive tang orientation, mounting holes, and port loions.
Transfer any components – Such as fuel temperature sensor, solenoid, or bracket.
Clean mounting surface – On engine block. Ensure no debris enters the timing case.
Install new pump – Align timing marks (if applicable). Install new O-rings or gaskets. Torque mounting bolts to specifiion.
Reconnect drive gear – Ensure proper backlash. Torque gear bolt.
Reconnect fuel lines – Use new crush washers or seals. Do not cross-thread.
Reconnect electrical connectors – Stop solenoid, etc.
Prime the fuel system – Use a hand primer (if equipped) to draw fuel through the filter and pump. Bleed air from the system.
Check for leaks – Start engine and inspect fuel lines and pump body.
Verify injection timing – Use a timing light or dial indior to confirm correct timing (refer to service manual).
Test drive and monitor – Verify power, idle quality, and no warning lights.
Quality Control
Material Verifiion: Housing and internal alloy composition tested.
Dimensional Inspection: Mounting flange, drive shaft dimensions, and port threads verified against OE blueprints.
Pressure Test: Pump tested for maximum pressure output and flow rate at specified RPM.
Calibration Test: Delivery volume per stroke and timing accuracy verified on a test bench.
Leak Test: High-pressure and low-pressure circuits tested for external leakage.
Governor Test: Speed control and response characteristics verified.
Visual Inspection: 100% checked for casting defects, damaged threads, or contamination.
Packaged Safely: Pump sealed in anti-static bag, boxed with foam support. Protective caps on all ports.
