Connecting Rod Bearings

Lower Crankcase And Oil Pan

The connecting rods are numbered 1 to 4, starting at the timing connecting rod. It is almost impossible to mix up the big-end bearing caps and connecting rods, because they are forged as a unit in production and then broken apart. The join between each connecting rod bearing cap and connecting rod is therefore unique.


Lower Crankcase

View Of Lower Crankcase:

The purpose of the lower crankcase is to reduce engine vibrations. This further reduces the level of noise inside the vehicle. There is a rubber gasket between the lower crankcase and the cylinder block.

Lower Crankcase Spacer Shims:

Lower crankcase spacer shims are used to even out any excessively large gaps between the transaxle and the lower crankcase (see Specifications).

Oil Pan
The engine is closed off at the bottom with a pressed steel oil pan which is directly attached to the lower crankcase. It is sealed with a 3 mm wide bead of sealer.
