Crankshaft Installation - Arctic Cat Cougar Service Manual

ENGINE
NOTE
Arctco recommends that ball type bear-
ings be heated to 75° C (167° F) in oil
before installation. Read Step 5 before
heating and installing bearings. During
bearing installation, support the crank-
shaft securely so the bearings can be
installed quickly. If a bearing cools and
tightens on the crankshaft before it is
completely installed, remove the bearing
with th6 puller and reheat the bearing.

e. Heat and install the bearings. Make sure the
bearings are fully seated.
Crankshaft Installation
1. Install the coolant pump and oil injection
pump driveshaft as described in this chapter.
2. Fill both of the outer crankshaft seal lip cavi-
ties with a low-temperature lithium-based
grease.
3. Install the seals over the ends of the crank-
shaft as shown in Figure 109. The shield side of
the seals must face out.
4A. On air-cooled Z 440, Panther 440 and 529
cc El Tigre engines, support the lower crankcase.
4B. On liquid-cooled engines, support the upper
crankcase by its crankcase studs.
CAUTION
Do not install a pin in the lubrication
passages.
5. If removed, make sure all the bearing locating
pins (Figure 110 or A, Figure 111) are installed.
6. On models so equipped, install the bearing
locating C-ring in the groove as shown in B,
Figure 111 and Figure 112.
NOTE
Installation is easier
if
the holes in the
main bearings' outer races for the lock-
ing dowel pins are in line and straight
down when lowering the crankshaft into
the crankcase lower half. It still may be
necessary to move the outer races
