is carried out carefully and accurately. The
following procedure involves tensioning
the belt twice to ensure that it is equally tensioned
between each gear. New and original belts are
tensioned to different figures.

from special tool LRT-12-045 is correctly
inserted in injection pump gear and timing tool
LRT-12-044 (LRT-12-085 if EDC) is fitted to
flywheel housing with pin located in flywheel slot.
Or if automatic: Timing tool LRT-12-044 is fitted
to engine backplate and pin located in ring gear.

60 Nm. The torque
meter should be used in the almost vertical
position.
