Fuel Supply Pump Installation

Install a new O-ring to the supply pump assembly.

Install the supply pump drive coupling.

HINT:

Line up the coupling with the groove in the camshaft end.

Install the supply pump assembly with the 2 bolts.

Torque:

21 N*m{210 kgf*cm, 15 ft.*lbf}

NOTICE:

Apply engine oil to the O-ring on the supply pump assembly.

Install the No. 1 injection pump protector with the 3 bolts.

Torque:

20 N*m{204 kgf*cm, 15 ft.*lbf}

Connect the suction control valve connector.

Temporarily install the fuel inlet pipe with the 2 clamps and nut.

Using the SST, first tighten the nut at the common rail end of the fuel inlet pipe.

SST

09023-38401

Torque:

27 N*m{275 kgf*cm, 20 ft.*lbf}

HINT:

1. Use of the proper SST is necessary to ensure that the correct torque is applied to the injection pipe nut.
   
2. Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
   
3. Make sure that the pipe is not deformed or twisted during installation.
   
4. If the pipe is deformed or twisted, or if it cannot be installed properly, replace the pipe with a new one.
   

Using the SST, tighten the nut at the supply pump end of the fuel inlet pipe.

Turn the retainer in the direction indicated by the arrow until it stops.

Insert the fuel tube connector into the injector.

Turn the retainer in the direction indicated by the arrow until it makes a "click" sound.

NOTICE:

If the fuel tube connector is not inserted into the correct position on the injector, the retainer will not turn beyond the point indicated in the illustration.

Connect the exhaust fuel addition injector connector.

Using pliers, slide the 2 clips to install the No. 3 fuel hose as shown in the illustration.

Using pliers, slide the clip to install the No. 5 fuel hose.
