Power Steering Pump Valve Bore - Incorrect Machining - Service Action S506
Issue:
A concern has arisen on a number of 2003 MY XK Series vehicles, within the above VIN ranges.
Incorrect machining of the valve bore in the power steering pump can cause the valve to stick resulting in a loss of power assistance.
Note:
Although there will be a loss of power assistance the driver will be able to maintain control of the vehicle with manual steering.
Vehicles that are affected by this Service Action are listed in this bulletin. Only those vehicles listed need to be checked and reworked if required.
Action:
Check the vehicles listed in this bulletin only, for suspect power assisted steering pumps and replace the pump where required.
Perform this work, if possible, prior to handover to the customer or alternatively, at the next available opportunity.
INSPECTION PROCEDURE
1. Raise vehicle.
2. From under the vehicle, check the spot drilling on the pump body, using a suitable mirror and flashlight. (Illustration 1). The viewing access is the gap between the air conditioning compressor and the front suspension beam.
3. The suspect pumps have a spot drilling on the cast face 25 mm from the edge nearest to the low-pressure port as shown in the illustration marked with the X in Illustration 2. The spot drilling will align with one side of the oval recess on the machined face of the pump body. Non-suspect pumps have a spot drilling approximately 17 mm from the edge nearest to the low pressure port as shown in the illustration marked with the check mark in Illustration 2.
Note:
Some pumps could have two spot drilling marks. You are requested to examine the position of the spot drilling mark nearest the low-pressure port only. (See Illustration 3a and 3b)
4. If you have identified a non-suspect pump at this stage no further action is required. If you have identified a suspect pump proceed to step 5 of this Workshop Procedure.
5. If you have identified a suspect pump at this stage, remove PAS pump. (See Workshop Manual, JTIS CD-ROM, section: 211-02, SRO 57.20.04).
Note:
For the new XJ Range vehicles only, when referring to the Workshop Manual, JTIS CD-ROM, section: 211-02, SRO 57.20.04, please note that the accessory drive belt will need to be removed before the air conditioning compressor and power steering pump are removed.
6. Check the date code on the PAS pump. If the code shows week 46, 48 or 50 in year 02 (Illustration 4) in addition to the drilling 25 mm from the edge, install a new PAS pump. (See Workshop Manual, JTIS CD-ROM, section: 211-02, SRO 57.20.04). Reinstall the existing pump if the code does not show week 46, 48, or 50 in year 02.
Note:
Pump must have both the drilling 25 mm from the edge, and a date code of 46, 48, or 50 to be replaced under this Service Action. Date code alone is not grounds for replacement.
Note:
For this Service Action campaign only it will not be necessary to install a new PAS reservoir when installing the new PAS pump.
Note:
For the new XJ Range vehicles only, when referring to the Workshop Manual, JTIS CD-ROM, section: 211-02, SRO 57.20.04, please note that the air conditioning compressor and new power steering pump will need to be installed before the accessory drive belt.
7. Lower vehicle.
