CHECKING FUNCTION OF POWER STEERING PUMP

Checking Vane Pump

1. Detach pressure line from pump and connect special tool (32 4 000). See «USING SPECIAL TOOL (32 4 000)»(ref-152291-S30298987172003012800000).
2. Close valve (A) and open valve (B). (Scheme 89)
3. Start engine. Ensure correct hydraulic fluid level in tank.
4. Heat hydraulic fluid to approximately 122°F (50°C) by moving steering wheel at increased engine speed.
5. Close valve (B) for a maximum 10 seconds and read off pressure. If pressure exceeds 1595 psi (110-120 bar) by more than 10 percent replace vane pump. If pressure is 10 percent less than 1595 psi 1595 psi (110-120 bar), check V belt tension. If V belt tension is OK, replace vane pump.
