Sump - removal and refitting

Note: New gaskets and sealing strips must be used on refitting.

Removal
1 Disconnect the battery negative lead and drain the engine oil (see Chapter 1).

2 Refer to Chapter 5, Part A and remove the starter motor.

3 Unbolt and remove the clutch cover plate.

4 Extract the sump securing bolts and remove the sump. If it is stuck, prise it gently with a screwdriver but do not use excessive leverage. If it is very tight, cut round the gasket joint using a sharp knife.

Refitting
5 Before refitting the sump, remove the front and rear sealing strips and gaskets. Clean the mating surfaces of the sump and cylinder block.

6 Stick new gaskets into position on the block using thick grease to retain them, then install new sealing strips into their grooves so that they overlap the gaskets (see illustrations).
