FIGURE 5-8. RELEASE VALVE ASSEMBLY AND GOVERNOR
(a) Install upper governor housing (figure 5-8, item 21) to crankcase (figure 5-8, item 23) leaving out the
governor housing gasket set (figure 5-8, item 22). Attach the housing to the crankcase with one hex
steel cap screw (figure 5-8, item 19) at the top and one at the bottom. Be sure the main bearing
(figure 5-8, item 24) fits properly in the housing (figure 5-8, item 21). Set the two attaching screws
finger tight. Use a feeler gage, measure the gap between the housing (figure 5-8, item 21) and
crankcase (figure 5-8, item 23) at the top and bottom of the housing (figure 5-8, item 21). Average
the two dimensions and add 0.005 inch (0.0127 cm). This will determine the selection of gaskets
Proper adherence to this procedure will minimize crankshaft end play.
