Measurement of Hydraulic Pressure

MEASUREMENT OF HYDRAULIC PRESSURE





1) Install STs to power steering pump.
(1) Drain the power steering fluid about 0.35 l (0.4 US qt, 0.3 Imp qt) from oil tank.
(2) Remove two bolts securing power steering pipes to engine.
(3) Install ST1, 2 and 3 between power steering pump and pipes using gasket (Part No. 34621AC020) and bolt (Part No. 34620A0010).

ST1 925711000 PRESSURE GAUGE
ST2 34099A0020 ADAPTER B
ST3 34099AC010 ADAPTER A

(4) Replenish power steering fluid up to specified level.

2) Using STs, measure regulator pressure.

Regulator pressure:
981 kPa (10 kg/cm2, 142 psi) or less





3) Using STs, measure relief pressure.

Relief pressure:
7,159 - 7,748 kPa
(73 - 79 kg/cm2, 1,038 - 1,123 psi)
