25 Install governor shaft assembly. Install washer and E–ring on governor shaft.
To prevent damage to oil seal while assembling crankcase cover, be sure to
use oil or grease on sealing edge of oil seal. If sharp edge of oil seal is cut or
bent under, seal may leak.
New gasket sets include three crankcase cover or sump gaskets: 0.005,0.009,
and 0.015 in. (0.13,0.23, and 0.38 mm) thick. Crankshaft end play should be
0.002 to 0.008 in. (0.05 to 0.20 mm) with one 0.015 in. (0.38 mm) gasket in
place. If end play is less than 0.002 in. (0.05 mm), extra gaskets may be added
in various combinations to attain the proper end play.
26 Apply a thin coating of oil or grease to sealing edge of oil seal. Wrap piece of thin paper around crank-
shaft so that seal will slide easily over shoulder of crankshaft.
27 Install new back crankcase cover gasket. Install back crankcase cover.
