Remove oil baffle plate – see operation "Oil Baffle Plate, Remove and Install". Mark order of con-rod bearing caps – bead (1) of con-rod bearing caps points to transmission side. Remove con-rod bearing cap from con-rod. The mating surfaces of the cod-rods and the con-rod bearing caps form an individual fit and as a result must not be damaged or replaced under any circumstances. To avoid damage, do not lay con-rods and con-rod bearing caps on mating surfaces.

Caution

Clean con-rod journal and con-rod bearing shell and lubricate slightly. This is necessary to prevent plastic thread tearing when con-rod bearing cap is removed. Plastigage is available for two measuring ranges – type: PG-1, green, bearing play of 0.025 to 0.075 mm. Type: PG-2, red, bearing play of 0.050 to 0.150 mm.

Plastigage is available via the "Opel/Vauxhall Workshop Equipment" catalogue.

  Measure

Remove con-rod bearing cap again.

Compare width of flattened plastic thread (arrow) with scale (on plastigage package).

Permissible con-rod bearing play: 0.010 to 0.061 mm.

Caution

When reading the value, do not confuse millimetres and inches on the measuring scale.
