Engine Lubrication; Engine Service Precautions - Arctic Cat Cougar Service Manual

150
Record all of the serial numbers and model
numbers that are applicable to your machine and
have these numbers with you when you order
parts. Always order parts by year, engine model
and serial number. If possible, compare the old
parts with the new ones before purchasing them.
If the parts are not alike, have the parts manager
explain the reason for the difference and insist
on assurance that the new part is correct and will
fit.
For convenience, write all of the frame and
engine identification numbers in the front of this
book.
ENGINE LUBRICATION
The engine is normally lubricated by the oil-
injection system. Refer to Chapter Ten for serv-
ice information covering the oil-injection pump.
Lubrication of a new or rebuilt engine or an
engine that has not been run for an extended time
may be initially supplemented by adding oil to
the gasoline used to power the engine. Refer to
Break-In Procedure in Chapter Three.
SERVICE PRECAUTIONS
Whenever you work on your Arctic Cat, there
are several precautions that you should follow to
help with disassembly, inspection and reassem-
bly.
1. In the text there is frequent mention of the left
or right side of the engine. This refers to the
engine as it is mounted in the frame, not as it sits
on your workbench. See Figure 3.
2. Always replace a worn or damaged fastener
with one of the same size, type and torque re-
quirements. Make sure to identify each screw
before replacing it with another. Screw threads
should be lubricated with engine oil, unless oth-
erwise specified, before torque is applied. If a
tightening torque is not listed in Table 10 at the
end of this chapter, refer to the torque and fas-
tener information in Chapter One.

3. Use special tools where noted. In some cases,
it may be possible to perform the procedure with
makeshift tools, but this procedure is not recom-
mended. The use of makeshift tools can damage
the components and may cause serious personal
injury. If special snowmobile tools are required,
purchase them through any Arctic Cat dealer.
Other tools can be purchased through your
dealer, from a motorcycle store or from an auto
parts store. When purchasing tools from an auto
parts store, remember that all threaded parts that
screw into the engine must have metric threads.
4. Before removing the first screw or nut, get a
number of boxes, plastic bags and containers
(Figure 4). Use these containers to separate and
organize the parts as they are removed. Also have
a roll of masking tape and a permanent, water-
proof marking pen to label each part or assembly.
If your snowmobile was purchased second hand
and it appears that some of the wiring may have
