Section 06 STEERING AND PROPULSION
Subsection 03 (JET PUMP)
Excessive play can come either from worn bearing
or damaged jet pump housing bearing surface.
LEAK TEST
Whenever performing any type of repair on the jet
pump, a leak test should be carry out.
Proceed as follows:
1. Remove impeller cover. Refer to
IMPELLER
COVER
in this subsection.
2. Install the pressure cap on pump housing.
REQUIRED TOOLS
PRESSUR E CAP
(P/N 529 036 283)
VACUUM/PRESSURE
PUMP (P/N 529 021 800)
3. Connect th
e vacuum/pressure pump to the

LEAK TEST PRESSURE
Maximum 70kPa (10PSI)
5. Pump must maintain this pressure for at least
5 minutes.
NOTE: Only 2 or 3 bubbles coming out from the

1. Small leak here i s acceptable
NOTICE
Repair any leak. Failure to correct a
leak will lead to premature wear of pump com-
ponents.
6. Disconnect pump and remove pressure cap.
7. Reinstall impeller cover. Refer to
IMPELLER
COVER
in this subsection.
PROCEDURES
NOTE: Whenever removing a part, visually check
for damage such as: corrosion, cracks, split,
break, porosity, cavitation, deformation, distor-
tion, heating discoloration, wear pattern, defec-
tive plating, missing or broken balls in ball bearing,
water damage diagnosed by black-colored spots
on metal parts, etc. Replace any damaged parts.
As a quick check, manually feel clearance and end
play, where a pplicable, to detect excessive wear.
