Idler Gear Disassembly/Assembly

IDLER GEAR DISASSEMBLY/ASSEMBLY
1. Disassemble in the order indicated in the table.
2. Assemble in the reverse order of disassembly indicated in the table.





Locknut disassembly note
1. Secure the SST and the idler gear assembly in a vise.
2. Remove the locknut.





Bearing race disassembly note
^ Remove the bearing race from the idler gear by using the SST





Assembly procedure
1. Press the new bearing races in by using the SST





2. Install a new bearing onto the idler gear shaft, and install the idler-gear, spacer, and bearing assembly.
3. Secure the SST and the idler gear shaft assembly in a vise.
4. Install the locknut.

Tightening torque
128 - 176 Nm (13 - 18 kgf-m, 95 - 130 ft-lbf)





Note
^ Use protective plates in the vise to prevent damage to the idler gear.
^ Read the preload when the idler shaft starts to turn.

5. Secure the idler gear in a vise.

Note
^ Measure several times and calculate the average value.

6. Measure the bearing preload by using the SST








Pull scale reading
0.3 - 8 N (0.03 - 0.9 kgf, 0.07 - 1.9 lbf)
Preload
0.03 - 0.8 Nm
(0.3 - 9.0 kgf-cm, 0.27 - 7.8 in-lbf)

Note
^ Preload is reduced by increasing the thickness of the spacer or increased by reducing the thickness.

7. If the specified preload cannot be obtained within the specified tightening torque, adjust it by selecting the proper spacer from below.





8. Apply ATF to a new O-ring and install it to the idler gear shaft.

O-ring inner diameter:
40.0 mm (1.575 in)
