CAUTION
• If the supply pump has been replaced, perform the “initialization of supply pump unit difference learning
value” using Multi-Use Tester in order to clear the correction data (learned pump unit difference) from the
engine electronic control unit. (See Gr13E.)

Installation procedure
Installation: Supply pump
• Position the No. 1 piston to the top dead center in the compres-
sion stroke in the following manner.
• Crank the engine to align the pointer with the “1 6” mark on
the flywheel.
• This will bring either the No. 1 piston or the No. 6 piston to the
top dead center in the compression stroke. If both the inlet
and exhaust rockers can be moved by hand by the amount of
valve clearance, that cylinder is at the top dead center in the
compression stroke. From that position, every turn of the
crankshaft will alternately bring the No.1 and No. 6 pistons to
the top dead center in the compression stroke. (See Gr11.)
• Install the supply pump while ensuring that the stamped line on
the supply pump timing cover is aligned with the stamped line on
the coupling block.
Installation: Injection pipe and fuel pipe
• Ensure that the pipe and mounting surfaces of the connector are
flat and free from damage.
• Bring the pipe into intimate contact with mounting surfaces of the
connector evenly, and temporarily tighten it without applying an
excessive force.
• Tighten it to the specified torque after temporary tightening.
