OIL PUMP | INSPECTION AND OVERHAUL NOTE: If the car has covered high mileage then be prepared to renew all the working parts contained in the oil pump.

1. First clean all the components as they are dismantled.
2. Visually check all the gears for obvious scoring or chipping of the teeth. Renew if they are in poor condition (photo).
3. Now work on the components contained within the cover.
4. Dismantle the pressure relief valve and inspect it for excessive wear and/or scoring (photo).
5. Pay special attention to the pressure relief valve spring. Note whether it shows signs of wear on its sides or whether it is on the point of collapse, if not collapsed.
6. Thoroughly clean the gauze filter housed within the relief valve bore.
7. Test the valve in its bore in the cover; it should have no more clearance than to make it an easy sliding fit. If any side movement is obviously apparent, then the valve and/or the cover will have to be renewed.
8. With earlier engines, inspect the oil filter bypass valve located in the pump cover. Prise out the seat and withdraw the valve and spring. Check the valve for cracks, nicks, or scoring.
9. Wash the stripped casting in clean paraffin or gasoline. Dry with a clean rag. Smear parts with clean engine oil before reassembly.
10. With the gears refitted in the pump housing, check the pump gear endfloat (photo). Lay a straight-edge across the two gear wheels and with a feeler gauge, measure the clearance between the straight-edge and the surface of the front cover. The clearance should be within the specified limits. If the measurement is less than the minimum specified, inspect the front cover recess for signs of wear.
11. Reassemble the relief valve components, and the bypass valve assembly on earlier models.
12. Lubricate the relief valve and fit it into its bore, then insert the relief valve spring. Fit the washer to the plug and screw it home. Tighten it to the specified torque.
13. Insert the bypass spring into its bore, place the valve on the spring and press in the valve seat with its concave face outwards. The outer rim should be located 0.020 to 0.040 in (0.5 to 1.0 mm) below the surface of the bore.

BODYWORK AND FITTINGS

DOOR RATTLES | TRACING AND RECTIFICATION

1. Check first that the door is not loose at the hinges and that the latch is holding the door firmly in position. Check also that the door lines up with the aperture in the body.
2. If the hinges are loose or the door is out of alignment, it will be necessary to reset the hinge positions as described in Section 10.
3. If the latch is holding the door properly, it should hold the door tightly when fully latched and the door should line up with the body. If it is out of alignment it needs adjustment as described in Section 10. If loose, some part of the lock mechanism must be worn out and requires renewal.

HOOD | REMOVAL AND REFITTING

1. Open and support the hood.
2. Detach the windscreen washer feed pipe at the reservoir.
3. Mark an outline around the hood hinge positions, then unscrew the retaining bolts while an assistant helps to support the hood in the raised position. With the bolts removed, lift the hood clear.
4. Refit in the reverse order of removal, checking hood alignment before fully tightening the retaining bolts.
