CAUTION: Remove the gears using a press and steelblocks as shown. Use of a iaw-type puller can damagethe gear teeth.
1. Securely clamp the countershaft assembly in a
bench vise with wood blocks.
2. Raise the locknut tab from the groove of the coun-
tershaft, then remove the locknut and the springwasher.
3.Remove the bearings using a bearing puller as
shown.
