    3. Rotor Eccentric ring Spring Vane Front cover Rear cover Feed Pump (HP2 Supply pump)

    4. Regulating valve Feed pump (discharge side) Suction inlet Filter Feed pump (suction side) Regulating valve body Spring Piston Bushing Regulating Valve (HP2 Supply pump)

    5. Stopper Coil Needle valve Spring Suction Control Valve (HP2 Supply pump)

    6. to Fuel tank to Common rail Feed pump Regulating valve SCV 1 SCV 2 Check valve Plunger Roller Inner cam Delivery valve Fuel Flow (HP2 Supply pump)

    7. DENSO EUROPE TECHNICAL TRAINING HP2 Supply Pump Inspection Procedure

    8. Fuel line diagram HP2 on Test bench

    9. HP2 Supply pump Inspection Procedure Flow

    10. Off-set input Procedure in DST-1 No off-set input After input off-set data Off set data are available on test specification sheet. (ETSI website) Procedure is described in the adjustment manual

    11. Start up settings for ECD Controller Pump select switch set to “11”

    12. Usage of the Pressure Regulator Valves Valve 1 : 0 - 60 Mpa Valve 2 : 60 – 120 Mpa Valve 3 : 120 – 180 Mpa Meaning pressure= 0 Mpa

    13. Manual is based on tests with Denso CPS21 test bench. (Operating differences can occur) Pictures of test steps are made without safety cover for better view. Actual tests should be done with use of Hartridge safety cover. (on AVM2PC) Be aware of the high temperatures of test oil during the tests that can cause injuries! Always Check ETSI for latest version of Test specifications! Adjustment manual for HP2 supply Pump
