Section 03 ENGINES
Subsection 01 (LEAK TEST)
A33C1AA
– Activate pump and pressurize engine to 34 kPa
(5 PSI). Do not exceed this pressure.
– Engine must stand this pressure during 3 min-
utes. If pressure drops before 3 minutes, check
tester kit by spraying a soapy solution on pump
cylinder, all plugs and fittings.
• If tester kit is leaking, bubbles will indicate
where leak comes from.
• If tester kit is not leaking, check engine as per
following procedure.
PROCEDURE
NOTE: A flow chart has been prepared as a visual
reference. See last page of this chapter.
Using flow chart and following text, pressurize
area to be tested and spray soapy solution at the
indicated location.
TEST PRESSURE: 34 KPA (5 PSI)
FOR 3 MINUTES
• If there is a leak at the tested location, it is
recommended to continue testing next items
before overhauling engine. There is a possi-
bility of more than one leak.
• If there is no leak at the tested location, con-
tinue pumping to maintain pressure and con-
tinue with next items until leak is found.
Engine

– All jointed surfaces and screw/stud threads of
engine:

pump. It indicates defective check valve in injec-
tion nipples.
– Remove cooling system cap.
Check for air bubbles in antifreeze. It indicates de-
fective cylinder head O-ring or cylinder base gas-
ket.
– Remove drive pulley then check crankshaft out-
er seal.
– Remove rewind starter and magneto system
then check crankshaft outer seal.
