Reassembly
4. Lubricate the crankshaft journal and connecting
rod bearing surfaces with engine oil. Install the
rod cap to connecting rod.
5. Three different types of connecting rod bolts
have been used in production and each has a
different torque value. See Figures 11-10 and
11-11. The 8 mm straight shank style rod bolts
must be torqued in increments to
22.7 N·m
(200 in. lb.) . The 8 mm step-down shank style rod
bolts must be torqued in increments to 14.7 N·m
(130 in. lb.) . The 6 mm straight shank style rod
bolts must be torque in increments to 11.3 N·m
(100 in. lb.) . Illustrated instructions are also
provided in the service rod package.

Install Balance Shaft
1. Lubricate the balance shaft bearing surfaces of
crankcase and balance shaft with engine oil.
2. Align the timing marks on the balance shaft gear
and the larger gear on the crankshaft. Lower
the balance shaft into the bearing surface in the
crankcase.
On CV460-495 models, the crankshaft and the
balance shaft must be rotated down three teeth
past the timing marks for the counterweights of
both shafts to clear when installing. After sliding
the balance shaft into place rotate the shaft
upward and check to make sure the two timing
marks are aligned. See Figure 11-12.
On all other models, make sure the balance
shaft gear, large crankshaft gear and the
governor gear teeth mesh and the timing marks
are aligned. See Figure 11-12.

6. Rotate the crankshaft until the piston is at top
dead center in the cylinder bore.
