Right-hand (front) oil seal 1 Support the engine/transmission on a trolley jack with a block of wood as an insulator.

2 Release the nuts on the right-hand flexible engine mounting at the base of the timing chain cover.

3 Raise the engine just enough to clear the side-member and anti-roll bar.

4 Remove the auxiliary drivebelt as described in Chapter 1, and the fuel pump as described in Chapter 4A.

5 Unscrew and remove the crankshaft pulley nut. To do this the crankshaft must be held against rotation by jamming the starter ring gear. Remove the starter, as described in Chapter 5A. Alternatively, if an assistant is available, apply the brakes fully with a gear engaged. Withdraw the pulley.

6 Note the fitted depth of the seal as a guide to refitting the new seal, then punch or drill two small holes opposite each other in the seal. Screw a self-tapping screw into each, and pull on the screws with pliers to extract the seal. Alternatively, the seal can be levered out of position using a suitable flat-bladed screwdriver, taking great care not to damage the crankshaft shoulder or timing cover.

7 Clean the timing cover, and polish off any burrs or raised edges, which may have caused the seal to fail in the first place.

8 Lubricate the lips of the new seal with clean engine oil, and carefully locate the seal on the end of crankshaft. Note that its sealing lip must face inwards. Take care not to damage the seal lips during fitting.

9 Using a suitable tubular drift (such as a socket) which bears only on the hard outer edge of the seal, tap the seal into position, to the same depth in the timing cover as the original was prior to removal.

10 Wash off any traces of oil, then refit the crankshaft pulley and nut. Tighten the crankshaft pulley nut to the specified torque, again jamming the flywheel to prevent the crankshaft rotating.

11 Refit the starter, if removed (Chapter 5A).

12 Refit and tension the auxiliary drivebelt (Chapter 1).

13 Lower the engine, reconnect the mounting.

14 Remove the flywheel as described in Section 9.

15 Make a note of the correct fitted depth of the seal in its housing. Punch or drill two small holes opposite each other in the seal. Screw a self-tapping screw into each, and pull on the screws with pliers to extract the seal.

16 Clean the seal housing, and polish off any burrs or raised edges, which may have caused the seal to fail in the first place.

17 Lubricate the lips of the new seal with clean engine oil, and carefully locate the seal on the end of the crankshaft.

18 Using a suitable tubular drift, which bears only on the hard outer edge of the seal, drive the seal into position, to the same depth in the housing as the original was prior to removal.

19 Wash off any traces of oil, then refit the flywheel as described in Section 9.
