Engine repair procedures - 1.6 and 1.8 litre 8 valve / Crankshaft and main bearings - removal


1 Disconnect the pistons and connecting rods from the crankshaft. Note that, although the engine has to be removed to remove the crankshaft, the cylinder head, pistons and connecting rods can be left in position.

2 At the flywheel end, undo and remove the six bolts securing the oil seal flange to the crankcase (see illustration). Withdraw the flange, seal and gasket.

3 Examine the main bearing caps. It will be seen that the caps are numbered 1 to 5 and that the number is on the side of the engine opposite the oil pump position. Identify these numbers. If they are obscured, then mark the caps in the same way as the connecting rod caps. Before removing the caps, push the crankshaft to the rear and check the endfloat using a feeler blade between the thrustwasher flanges on No 3 main bearing and the crankshaft web (see illustration). It must not exceed the specified maximum.

4 Remove the bearing cap retaining bolts, remove the bearing caps and lift out the thrustwashers from each side of the centre main bearing.

5 Lift out the crankshaft and then remove the top half bearing shells. If the main bearings are not being renewed, make sure the shells are identified so that they go back into the same bearing cap the same way round
