Opel Corsa B 1993–2000 Service and Repair Manual: Crankshaft front oil seal - renewal
1. Remove the crankshaft sprocket as described in the procedure for oil pump removal. There is no need to remove the camshaft sprockets or belt backplate. Recover the spacer from behind the sprocket.
2. Drill or punch a small hole in the face of the oil seal. Screw in a self tapping screw and use this to lever out the seal. Clean the seal seat.
3. Grease the lips of a new oil seal. Fit the seal, lips inwards, and seat it using a piece of tube, some washers and the crankshaft sprocket bolt.
4. Thinly coat the outer face of the spacer with sealant to GM spec 15 04 200/8 983 368. Push the spacer onto the crankshaft.
5. The remainder of refitting is the reverse of the removal procedure. Remember to fit a new camshaft toothed belt.
Pistons and connecting rods - dismantling and reassembly
1. With the pistons and connecting rods removed they may be separated if necessary as follows.
2. Note the relative orientation of rod and piston. When fitted, the arrow on the piston crown points to the camshaft sprocket end of the engine, and the bosses on the connecting rod face towards the flywheel.
3. Remove one of the circlips which secure the gudgeon pin. Push the gudgeon pin out of the piston and connecting rod using a wooden or brass rod. No great force should be necessary.
4. When refitting, fit the connecting rod into the piston and make sure they are the right way round. Oil the gudgeon pin and push it home, then secure it with the circlip.
