Sub-Section 01 (OIL INJECTION SYSTEM)
07-01-3
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.
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 N•m (27 lbf•in).
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
WARNING : Whenever oil system compo-
nents are disconnected or replaced, a
pressure test must be done before starting en-
gine. Ensure to verify oil line ends for damage.
Always cut damaged end before reinstallation.
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 to check valve of
oil injection reservoir vent.
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 /
replace component leaking. To ease leak
search spray a solution of soapy water on com-
ponents, bubbles will indicate leak location.
NOTE : The system must maintain a pres-
sure of 21 kPa (3 PSI) for at least 10 min-
utes. Never pressurize over 21 kPa (3 PSI).
CAUTION : If any leak is found, do not
start the engine and wipe off any oil leakage.
– Disconnect pump gauge tester and remove
hose pinchers.
