Check The High-Pressure Fuel Pump Case And Fuel Pump Lifter
WARNING: This page is about a different variant/trim than selected.
- Check that the high-pressure fuel pump case and the fuel pump lifter have no deformation, cracks or other damages.
- Check the clearance between the fuel pump lifter and high-pressure fuel pump case bore. Check the clearance between fuel pump lifter and high-pressure fuel pump case bore by measuring the outer diameter of fuel pump lifter and the inner diameter of high-pressure fuel pump case bore respectively.
- Measure the outer diameter of fuel pump lifter with a micrometer.NOTE:
- Measurement should be performed at a temperature of 20°C (68°F).
- Measure at several points, and take notes of the value of most worn location.
- Using a caliper gauge, measure the inner diameter of high-pressure fuel pump case bore.NOTE:
- Measurement should be performed at a temperature of 20°C (68°F).
- Measure at several points, and take notes of the value of most worn location.
- Calculate the clearance between the fuel pump lifter and high-pressure fuel pump case bore. If it is not within the standard, replace the fuel pump lifter and high-pressure fuel pump case as a set.
Clearance between fuel pump lifter and high-pressure fuel pump case bore:
Standard
0.055 - 0.108 mm (0.0022 - 0.0043 in)
- Measure the outer diameter of fuel pump lifter with a micrometer.
