CAUTION: The following test procedure involves

testing maximum pump pressure output and flow

control valve operation. Do not leave valve closed

for more than three seconds as the pump could be

(12) Close valve fully three times and record high-

est pressure indicated each time. All three read-

ings must be above specifications and within

345 kPa (50 psi) of each other.

• Pressures above specifications but not within

345 kPa (50 psi) of each other, replace pump.

• Pressures within 345 kPa (50 psi) of each other

but below specifications, replace pump.

(13) Open the test valve and turn the steering

wheel to the extreme left and right positions three

times against the stops. Record the highest pressure

reading at each position. Compare readings to the

pump specifications chart. If pressures readings are

not within 50 psi of each other, the gear is leaking

internally and must be replaced.

CAUTION: Do not force the pump to operate

against the stops for more than 2 to 3 seconds at a

time because, pump damage will result.
