Technical notes
The Wärtsilä 32 uses a split H-profile connecting rod with a serrated big-end joint that allows the piston and rod to be withdrawn through the cylinder without splitting the bottom-end around the crankpin. The serrations locate the joint precisely, and the bolts must be tensioned hydraulically to the specified pre-load, because incorrect tension risks fretting or fatigue at the joint. Order against the catalogue section for the engine variant and replace the big-end bearing shells at the same time. Always use the correct hydraulic tensioning tools and verify bolt elongation on assembly.
