slightly to engage the locking pins, but
little movement should be required.
NOTE
Step 7A, 7B or 7C describes crankshaft
installation; however, because of the
number of separate procedures required
during installation, read all the proce-
dures included in Step 7 A, 7B or 7C
before installing the crankshaft.
7 A. On air-cooled Z 440 and Panther 440 en-
gines, align the crankshaft with the lower crank-
case half and install the crankshaft with the
connecting rods up (Figure 113). Observe the
following:
a. Make sure that the crankshaft center oil seal
ring fits into the crankcase groove as shown
in Figure 114.
b. Make sure that the crankshaft center drive
gear (Figure 102) meshes properly with the
gear on the coolant pump and oil injection
pump drive shaft (Figure 103).
c. Be sure the groove in the center bearing fits
around the C-ring (Figure 112).
d. Make sure the end seals fit into the crank-
case properly.
e. Check that all five of the bearing locating
pins properly engage the holes in the outer
races of all five bearings. Try to turn each
bearing's outer race to make sure the pin
properly seats in the bearing.
CAUTION
It is important that the bearings and
seals are properly aligned with the pins,
C-ring and grooves, before continuing
assembly. The upper half of the crank-
case cannot be installed until the crank-
shaft, seals and bearings are completely
seated in the lower half. Attempting to
force the parts into place will only dam-
age the parts.
7B. On 529 cc El Tigre engines, align the crank-
shaft with the lower crankcase half and install the
crankshaft with the connecting rods down (Fig-
ure 115). Observe the following:
