2004 Chevrolet Tracker Parts Questions & Experts Answers

• Q: How to service and repair the power steering pump on 2004 Chevrolet Tracker?

  A: You should start by taking out the Power Steering Pump until it leaves your car to perform maintenance work. You must then cleanse all exterior parts before setting the pump into a tabletop clamp. Remove the bolt that attaches the power steering gear outlet hose connector followed by separation of the connector and its o-ring. Service personnel should take out the pressure switch along with the flow control valve from the pump body. You must remove 4 bolts (1,2,3,4) to expose the rear pump cover which includes the o-ring seal before carefully separating the pump shaft cam ring from one another to maintain the vane order for reassembly. Begin vanes removal from the rotor and proceed to take off the snap ring then the rotor and side plate before removing the o-rings. After extraction of the shaft combined with its integrated pulley users must separate the oil seal from the pump body. The Power Steering Pump requires replacement if inspections reveal body or cover cracks or leaks alongside significant wear, cracks or leaks. Severe wear or damage on the side plate and shaft requires assembly replacement. A comprehensive examination of the cam ring for wear damage should be completed since finding damage requires replacing the pump assembly. The Power Steering Pump seal kit requires replacement when inspecting the sliding surfaces of rotor and vanes for any wear or damage. A feeler gauge should be used to measure vane-to-rotor clearance to verify it stays between 0.015 - 0.027 mm (0.0006 - 0.0011 inch). Replacement of rotor and vane components from the Power Steering Pump seal kit is needed if this range is exceeded. Inspection should include checking for blockages within the relief valve fluid passage as well as the connector orifice while inspecting the relief valve sliding surface for any signs of damage or wear. Measuring the free length of the flow control valve spring requires dial calipers which must fall between 19.0 - 22.0 mm (0.740 - 0.866 inch); if the measurement does not pass the test criteria the Power Steering Pump should be replaced.
