Install the idle gear bearing onto the idle shaft, then
install the idle gear, adjust shim, spacer, and
bearing.
Note
Install the idle gear with the notches in the
teeth facing as shown.
FE engine: 2 notches
F6 engine: 3 notches
Secure the idle shaft in a vise with the SST; then
tighten the locknut to the lower limit of the tighten-
ing torque.
Tightening torque:
128 N-m (13 m-kg, 94 ft-lb)
Note
Use the protective plates in the vice to pre-
vent damage to the SST.
Check and adjust the idle gear bearing preload.
(1) Turn the idle gear assembly and SST over, and
secure the gear in the vice.
Note
Use protective plates in the vice to prevent
damage to the idle gear.
(2) Attach the SST and spring scale or a torque
wrench, and measure the preload while tight-
ening the locknut.
Tightening torque:
128—177 N-m (13—18 m-kg, 94—130 ft-lb)
Preload:
0.03—0.9 Nm
(0.3—9.0 cm-kg, 0.26—7.8 in-lb)
Value indicated on pull scale:
0.3—9 N (0.03—0.9 kg, 0.066—1.98 lb)
Note
Read the preload when the idle shaft starts to
turn.
