A Use a block of wood and a hammer to drive the new seal squarely into position

8 If the timing cover is still in place, remove the auxiliary drivebelt as described in Chap-ter 1.

9 Remove the crankshaft pulley. To prevent the crankshaft from rotating whilst the crankshaft pulley central bolt is slackened, engage top gear and have an assistant press the brake pedal firmly. Slacken the pulley bolt. On automatic transmission models, it will be necessary to remove the starter motor (Chapter 5A) and have an assistant wedge a large flat-bladed screwdriver between the driveplate teeth and the transmission casing

- ensure the screwdriver doesn't slip.

10 Carefully prise the seal from the timing cover with a screwdriver or seal removal tool (see illustration) Take great care not to scratchthe cover bore or the surface of the crankshaft in the process. n The seal may be easier to remove if the old seal lip is cut with a sharp utility knife first (see illustration 8.2b).

11 Clean the bore in the cover and coat the outer edge of the new seal with engine oil or multi-purpose grease. Apply a little grease to the seal lip.

12 Using a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the new seal into place.

Make sure it's installed squarely and driven in so the outer edge of the seal is flush with the timing cover. If a socket isn't available, a short section of large diameter pipe will also work.

13 Refit the crankshaft pulley and tighten the retaining bolt to the specified torque. Prevent the crankshaft from rotating using the same method employed during removal.

8.7b The new seal's outer edge should be flush with the timing cover

14 Refit the auxiliary drivebelt as described in

Chapter 1.

9 Camshaft oil seal -renewal

Note: This procedure applies only to 4E-FEand 4A-FE Non-VVT-i engines. No camshaft oil seals are fitted to the VVT-i engines.

1 Refer to Section 4 and remove the cylinder head cover, then remove the timing belt.

2 Use a large spanner to hold the exhaust camshaft at its hexagonal section, while removing the bolt from the camshaft sprocket (see illustration), then pull off the sprocket.

3 Note how far the seal is seated in the bore, then carefully pry it out with a small screwdriver (see illustration). Don't scratch the bore or damage the camshaft in the process (if the camshaft is damaged, the new seal will end up leaking).

4 Clean the bore and coat the outer edge of the new seal with engine oil or multi-purpose grease. Apply multi-purpose grease to the seal lip.

5 Using a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the new seal into place with a seal installer or large socket. Make sure it's installed squarely and driven in to the same depth as the original. If a socket isn't available, a short section of pipe will also work. Note: There isn't much room for a hammer, so you can also lever between the
