Idler Gear: Reassembly

Press bearing outer races.

Fig 1: Pressing Bearing Outer Races
Install idler gear bearing onto idler shaft, then install idler gear, adjustment shims, spacer, and bearing.
NOTE: Use protective plates in vise to prevent damage to SST.

Fig 2: Assembling Idler Gear Components
Secure idler shaft in a vise with SST(0K130 191 034) and tighten lock nut to lower limit of tightening torque.
Tightening torque: 95~130 lb-ft. (128~176 N.m, 13~18 kg-cm)

NOTE: Use protective plates in vise to prevent damage to idler gear.
Check and adjust idler gear bearing preload.
1. Turn idler gear assembly and SST(0K130 191 034) over and secure gear in vise.
2. Attach SST(0K130 191 034) and spring scale or torque wrench and measure preload while tightening lock nut.
NOTE: Read preload when idler shaft is rotating.

Tightening torque: 95~130 lb-ft. (128~176 N.m, 13~18 kg-cm)

Preload: 0.27~7.8 lb-in. (0.03~0.8 N.m, 0.3~0.9 kg-cm)

Fig 4: Measuring Preload With Spring Scale

Fig 5: Measuring Preload Using Torque Wrench
NOTE:
- The maximum allowable number of shims is 7.
- Preload is reduced by increasing thickness of shims, or increased by reducing thickness.

If specified preload cannot be obtained within specified tightening torque, adjust by selecting proper adjustment shims. Refer to ADJUSTMENT SHIM SIZES table.
