SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD (RF Turbo)]

id0114f1805700

Caution

•  Fuel line spills and leakage on the parts are dangerous. Fuel can ignite and also deteriorate the parts. To prevent this, always cover the mouths of the removed parts in the fuel system with rags to soak up the fuel.

•  To prevent the fuel injection pipe from clogging, be careful that foreign material has not entered the pipe. Also, be sure to tighten the bolts with the specified tightening torque when installing the fuel injection pipe.

•  To prevent fuel leakage, follow the procedure indicated in the workshop manual when removing and installing the fuel injector.

•  The fuel injection pipe can be removed and reinstalled up to five times. Be sure to record in the service record when removing and installing the fuel injection pipe. If removing it for the sixth time, be sure to replace it with a new one.

•  If fuel does not pass through the fuel filter, foreign material may have penetrated in the supply pump, and this may cause a malfunction resulting in damage to the supply pump. Therefore, do not install the fuel hoses (main and return side) in reverse. When installing the fuel hose, always follow the Fuel Hose Installation Note in the Workshop Manual and perform the procedure. (See Fuel Hose Installation Note.)

Note

•  If the supply pump is replaced, always perform each adjustment procedure using the following steps.

STEP	ACTION	PAGE/CONDITION
1	Replace the supply pump.	–
2	Turn the engine switch on.	–
3	Perform supply pump data reset procedure.	Engine coolant temperature 60—100 °C {140—212 °F} (See SUPPLY PUMP DATA RESET [MZR-CD (RF Turbo)].)
4	Start the engine. Note •  Idling for 30 s or more.	Verify that the MIL does not illuminate.
5	Turn the engine switch off.	–
6	Turn the engine switch on (Engine off).	–
7	Perform KOEO self-test procedure.	(See KOEO/KOER SELF TEST [MZR-CD (RF Turbo)].)
8	Turn the engine switch off.	–
9	Wait for 20 s.	–
10	Start the engine.	–
11	Perform KOER self-test procedure.	Warm up until the exhaust gas temperature (EXHTEMP1, EXHTEMP2, EXHTEMP3 PID) is 100 °C {212 °F} or more. (See KOEO/KOER SELF TEST [MZR-CD (RF Turbo)].)
12	Turn the engine switch off.	–

Supply Pump Removal Note

1.  Verify that timing marks are correctly aligned.

Caution

•   Do not fully tighten the anti-rotation bolt to prevent damage to the supply pump bracket and supply pump pulley.

2.  Lock the supply pump pulley against rotation using the FIP repair kit (RFY1-13SM0).
