Plain Bearing Surface Inspection
Plain bearing surfaces are used for both ends of the camshaft and the flywheel end of the crankshaft.
1. Inspect the camshaft surfaces, one in the crankcase (3) (Figure 13-92, Page 13-41) (and the other in
the crankcase cover (1) (Figure 13-93, Page 13-41). Using an inside micrometer or telescoping gauge,
measure the inside diameter of each bearing surface. If the inside diameter is greater than 0.9080 inch
(23.063 mm), replace the crankcase and/or the crankcase cover.
2. Inspect the crankshaft bearing surface (2) in the crankcase. Using an inside micrometer or telescoping
gauge, measure the inside diameter of the bearing surface. If the inside diameter is greater than
1.1841 inches (30.075 mm), replace the crankcase (Figure 13-92, Page 13-41).
Crankshaft Installation
Read DANGER and WARNING on page 13-1.
1. Installation is the reverse of removal. See Crankshaft and Counterbalance Removal, Page 13-35.
2. Tighten the four nuts (2) for counterbalance guide shaft to 50 in-lb (5.9 N·m) (Figure 13-73,
Page 13-34)
3. If the link rod was removed from the PTO side of the crankshaft, support the crankweb as shown, slide the
link rod onto the crankshaft, and install the key. Press the spur gear and helical gear onto the crankshaft
