Testing Oil-Injection Pump
NOTE: These tests must be made with the snowmo-
bile and the oil at a “room” temperature of 20°-30° C
(68°-86° F).
1. Disconnect the oil pump cable/control rod from the
control arm on the pump.
2. Clamp off the oil-supply hose between the oil reser-
voir and oil pump; then remove the supply hose from
the pump.
3. Attach a suitable length of clear oil-supply hose to
the oil pump; then using Oil Injection Usage Tool,
fill the hose with Arctic Cat Synthetic APV 2-Cycle
Oil.
NOTE: Use clear hose when performing this test to
simplify the detection of air in the testing equipment.
NOTE: On all engines, use Arctic Cat Synthetic APV
2-Cycle Oil. Use of any other oil will cause inaccurate
oil consumption readings.
NOTE: When filling the oil-supply hose with oil, do
not fully insert the usage tool into hose. There must
be enough room around the tip of the tool and the
hose to allow air in the hose to escape.
4. Fill the usage tool with recommended oil to the 0
line.
5. Wipe the tip of the tool to remove excess oil; then
attach the tool to the oil-supply hose and remove the
bulb.
6. Secure the tool to the oil reservoir by twisting the
rubber strap one half turn and placing the rubber
strap around the tool and the oil reservoir filler neck.
NOTE: On the F 570, the tool can be secured to the
air silencer.
NOTE: On CFR/Crossfire/M-Series to access the oil
pump, tip the snowmobile on its left side; then using
a torx-bit, remove the screws securing the center
belly pan (skid plate) to the front end.
NOTE: On the 600/800/1000 cc, the control rod must
be secured in the FULL-CLOSED (Idle) position.
Secure the rod to a convenient engine component
away from any moving parts. Securing the rod pre-
vents misalignment of the control arm due to engine/
chassis movement.
7. With the control arm secured in the FULL-CLOSED
(Idle) position, start the engine and run the engine at
recommended RPM for 3 minutes. Compare the
amount of oil used against the specifications on the
chart in Section 1.
NOTE: Before starting the engine, make sure that
no air is present in the testing equipment.
8. With the control arm secured in the FULL-OPEN
position (line-to-line), run the engine at recom-
mended RPM for 2 minutes. Compare the amount of
oil used against the Oil Consumption Specifications
chart in Section 1.
9. If the oil-injection pump output does not meet the
specifications, see Testing Oil-Injection Check
Valves in this sub-section.
10. Disconnect the oil usage tool, remove the plug from
the reservoir, attach the oil-supply hose to the oil res-
ervoir.
NOTE: After testing the oil pump, the oil pump must
be correctly synchronized with the carburetors/throt-
tle bodies (see Synchronizing Oil-Injection Pump on
page 31 in this section).
Testing Oil-Injection
Check Valves
In the event an engine problem occurs due to lack of
lubrication, the oil-injection pump check valves should
be tested using a vacuum pump to make sure the check
valves are operating properly.
When testing the check valves, remove them from the
pump assembly.
1. Remove the check valves from the oil-injection
pump.
731-551A
2. Attach the vacuum test pump hose to the check
valve.
! WARNING
Always wear safety glasses when performing this test.
! WARNING
Keep hands and clothing away from all moving or
rotating parts.
CAUTION
Whenever servicing the oil-injection system, use a 100:1
gas/oil mixture in the gas tank to ensure adequate
engine lubrication. Failure to use the 100:1 mixture to the
oil-injection system will result in severe engine damage.
