Note: New flywheel/driveplate bolts must be used on refitting.

1 Remove the flywheel/driveplate and the engine adapter plate.

2 Extract the seal using an oil seal removal tool if available. It may also be possible to remove the oil seal by drilling the outer face and using self-tapping screws and a pair of grips.

3 Clean the oil seal housing, then carefully wind a thin layer of tape around the edge of the crankshaft to protect the oil seal lip as the seal is installed.

4 Ideally, the new oil seal should be installed using a tool similar to that shown (see illustration).

A suitable tool can be improvised using a metal tube of suitable diameter, a metal disc or flat bar, and two flywheel bolts. Draw the seal into position using the two flywheel bolts. Make sure that the seal lip faces into the engine.

5 With the oil seal installed, carefully pull the tape from the edge of the crankshaft.

6 Refit the engine adapter plate and the flywheel/driveplate.
