22. Lubricate the camshaft MAG bearing journal,
camshaft lobes, and camshaft bearing bore in
crankcase with clean engine oil.
23. See Figure 93. Verify that valve tappets are clear
of camshaft lobes, and install camshaft into bearing
bore aligning timing mark on camshaft gear root with
timing mark on crankshaft gear tooth (
A
).
24. Lubricate the camshaft and crankshaft gear mesh (
B
)
with clean engine oil.
25. Lubricate the camshaft PTO bearing journal (
C
), and
camshaft bearing bore in crankcase cover with clean
engine oil.
26. Verify two locating pins are present on crankcase
flange. Install
new
locating pins if damaged or
missing.
27. Verify that mating surfaces of crankcase and
crankcase cover are clean and dry. Any dust or dirt
left on mating surfaces can cause leaks.
28. See Figure 94. Apply a bead of liquid gasket
0.071
inches
(1.8 mm) thick to crankcase cover. Bead must
be a continuous closed loop with an overlap
0.236
inches
(6 mm).
NOTE:
Crankcase cover must be installed within five
minutes of liquid gasket application. If time limit is
exceeded, scrape off liquid gasket and reapply.
29. Install oil seal protector sleeve on crankshaft.
NOTE:
Use black electrical tape if oil seal protector
sleeve is not available.
30. Apply a thin film of clean engine oil to PTO bearing oil
seal lip.
31. Verify that paddle of governor crank is still in contact
with governor cup. Since this observation cannot be
made after installation of the crankcase cover, hold
governor crank as described and paint a line across
crankcase boss, flat washer, and governor crank as
shown in Figure 95.
NOTE:
Keep the paint marks aligned until after
installation of the governor lever to ensure that
governor cup does not drop off the governor shaft.
32. Install crankcase cover onto locating pins.
33. Remove oil seal protector sleeve (or black electrical
tape) from crankshaft.
34. Start six hex flange screws to fasten crankcase cover
to crankcase. Proceed as follows:
NOTE:
Verify cleanliness of crankcase cover screws.
Friction caused by dirt will result in a false torque
reading.
