Wärtsilä Vasa 32 Engine Spares

The Wärtsilä Vasa 32 is a medium-speed, four-stroke engine with a 320 mm bore, installed for main propulsion on smaller vessels and as an auxiliary generator prime mover across the fleet. It is one of the most widely fitted medium-speed engines in service, so its wear-part spares are a steady, high-frequency sourcing line. The defining wear items are the cylinder liner with its anti-polishing ring, which scrapes carbon from the piston top land to prevent bore polishing, and the split H-profile connecting rod, whose serrated joint requires hydraulic bolt tensioning for correct pre-load. The cylinder head carries a safety relief valve whose setting must be confirmed against the cylinder layout, and the fuel injection valve uses shielded fuel pipes and leak containment to meet SOLAS engine-room standards. Wärtsilä identifies these components by catalogue section reference tied to the engine variant — for example section 100-008A for the liner with anti-polishing ring — so the variant and cylinder layout must be confirmed before sourcing. This series page lists the curated, section-anchored Vasa 32 spares that make up a routine overhaul, each carrying its reference so an engineer can verify fitment before requesting a quote.
