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.
Torque these to 22.7 N·m (200 in. lb.)
8 mm Straight Shank
Torque these to 14.7 N·m (130 in. lb.)
8 mm Step-Down
Torque these to 11.3 N·m (100 in. lb.)

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.
