GENERAL
Whenever repairing the oil injection system, al-
ways verify for water infiltration in reservoir.
Perform also a pressure test of the oil injection
system.
All Models Except XP and HX
1,2, Clamp and Hose
Verify oil filler neck hose for damage. Always en-
sure that clamps are well positioned and tight-
ened. Torque clamps to 3.5 N•m (31 lbf•
in
).
All Models
3, Check Valve
Black side of the one-way check valve is the valve
outlet. It allows air to get in reservoir.
4, Oil Filter
Oil filter should be replaced annually.
OIL SYSTEM PRESSURIZATION
Pressure Test
Proceed as follows:
– Fill up oil reservoir.
– Install a hose pincher to rotary valve shaft oil
supply hose.
– Install a hose pincher to rotary valve shaft oil
return hose.
– Install a hose pincher to oil injection pump sup-
ply hose.
– Connect pump gauge tester (P/N 529 021 800)
to check valve of oil injection reservoir vent.
NOTE:
Use the same pump included in the EN-
GINE LEAK TESTER KIT (P/N 295 500 352).
TYPICAL
1. Connect pump to check valve
– Pressurize oil system to 21 kPa (3 PSI). If pres-
sure is not maintained, locate leak and repair/re-
place component leaking. To ease leak search
spray a solution of soapy water on compo-
nents, bubbles will indicate leak location.
NOTE:
The system must maintain a pressure of
21 kPa (3 PSI) for at least 10 minutes. Never pres-
surize over 21 kPa (3 PSI).
– Disconnect pump gauge tester and remove
hose pinchers.

WARNING
Whenever oil system components are dis-
connected or replaced, a pressure test must
be done before starting engine. Ensure to
verify oil line ends for damage. Always cut
damaged end before reinstallation.
-
CAUTION
If any leak is found, do not start the engine
and wipe off any oil leakage.
