2. No Recovery - Continued.
(f) With engine idling, close
load valve and read pressure
gage. Pressure must be 900
to 1000 psi (62.07 to 68.97
bars).
If pressure is less than 900 psi
(62.07 bars), repair or replace
power steering pump
WP 0087 00 or WP 0086 00).
3. Check for sufficient pump flow
as follows:
(a) Perform steps a through e of
step 2.
WARNING
Maximum flow rate is 7 gpm (26.5 liters/min). Flow rate in
excess of 7 gpm (26.5 liters/min) will damage steering gear and
could cause loss of steering and injury to personnel.
(b) With engine idling, read
flow meter. Rate of flow
must be 7 gpm (26.5 liters/
min).
Repair or replace power steering
pump (WP 0087 00 or
WP 0086 00).
(c) With engine idling, close
load valve until pressure
gage indicates pump relief
and pump relief pressure
drops to 0. Immediately
open load valve. Flow rate
must return to 7 gpm (26.5
liters/min).
Repair or replace power steering
pump (WP 0087 00 or
WP 0086 00).
(d) Run engine at 2100 rpm and
fully close load valve until
pressure
gage
indicates
pump relief and flow rate
drops to 0. Immediately
open load valve. Flow rate
must return to 7 gpm (26.5
liters/min).
Repair or replace power steering
pump (WP 0087 00 or
WP 0086 00).
4. Check for defective teflon seals
in steering control valve.
Repair or replace steering gear
(WP 0089 00 or WP 0088 00).
5. Check for steering gear control
valve sticking.
Repair or replace steering gear
(WP 0089 00 or WP 0088 00).
3. External Oil Leaks from Steering Gear.
NOTE
External leakage is not acceptable from steering gear.
1. Check for leak at rubber relief
plug (on frame side of steering
gear).
Repair or replace steering gear
(WP 0089 00 or WP 0088 00).
2. Check for leak at shaft seals.
Repair or replace steering gear
(WP 0089 00 or WP 0088 00).
