If necessary scribe a circle onto retainer (3). Refer to Illustration 12 if working on a 12K, 140K, or 160K and refer to Illustration 13 if working on a 120K. Drill three evenly spaced 6.4 mm (0.25 inch) diameter holes into retainer (3).Note: Once the bearing adjustment is complete, the modified retainer can be reused.
Measure and record the thickness of retainer (3) .
Install sprocket (4). Install retainer (3). Do not use shims. Install bolts (2) finger tight against retainer (3). Tighten bolts (2) to the seating torque of 80 N m (59 lb ft). Repeat until bolts (2) no longer move. Rotate the housing three full revolutions. Bolts (2) will have to be tightened to 80 N m (59 lb ft) several times. After each tightening sequence rotate, the housing three full revolutions until the bolt torque has equalized at 80 N m (59 lb ft).
Loosen bolts (2) and retighten finger tight against retainer (3). Rotate the housing three full revolutions.
