MOUNTING THE PRESSURE FEED PIPE
(1)
Mount the new pressure feed pipe to the supply pump and com-
mon rail.
Tightening Torque:
44 N·m {449 kgf·cm, 32 lbf·ft}
(2)
Mount the 2 clips with 2 nuts and fix the pressure feed pipe.
! CAUTION
Always replace the pressure feeding pipe by a new one because
the pipe is subjected to high pressure; reusing the same pipe
result in a fuel leak.
5.
CONNECTING THE HARNESS
(1)
Connect the connector to the fuel temperature sensor and suction
control valve of the supply pump.
! CAUTION
Before connecting the connectors, make sure that the terminals
are free of a spark mark.

8.
UPDATING THE SUPPLY PUMP LEARNED VALUE
(1)
When replacing the supply pump, update the learned value
recorded in the engine ECU by using HINO-DX.
(Refer to the HINO-DX user's manual.)
! CAUTION
•
When the learned value is not updated, common rail pres-
sure control cannot be performed correctly. This may cause
engine stall and/or excessively high common rail pressure.
Therefore, make sure to update the learned value when
replacing the supply pump.
•
After the supply pump is mounted, start the engine for a trial
run to check for fuel leakage from around the supply pump.
