INSTALLATION
Mainshaft and Countershaft Bearings
1. Place crankcase on press with inside surface of crank-
case downward.
2. Lay bearing squarely over bore with printed side of bear-
ing upward. Place section of pipe or tubing (slightly
smaller than outside diameter of bearing) against outer
race. Press bearing into bore until bearing bottoms
against shoulder.
3. Install new retaining ring with beveled side facing away
from bearing.
Shift Drum Bushing
1. Place crankcase on press with outside surface of crank-
case downward.
2. See Figure 6-48. Lay bushing squarely over bore. Locate
socket or pipe that is slightly larger than diameter of
bushing. Place socket or pipe on bushing and press into
bore until bushing is flush with or 0.020 in. (0.508 mm)
below inside surface. If using a pressing tool larger than
diameter of bushing, the pressing tool will bottom against
crankcase when bushing is flush with top surface.
