The Wärtsilä 20 series, in four to nine cylinder versions, drives generators on vessels of every type. The 6L20 is the most common, and its maintenance follows a predictable pattern.
Spares to plan for
- Fuel injectors, nozzles and injector sleeves
- Cylinder liners, with liner O-rings and anti-polishing rings
- Pistons, piston rings and gudgeon pin bearings
- Connecting rod bearings and big end bolts
- Inlet and exhaust valves, valve seats and rotators
Wärtsilä has updated many 20-series components over the years, and engines built under licence can differ again. Include the engine serial number so the current revision is quoted.
We supply genuine and quality-alternative Wärtsilä 20 spares and can source both for comparison.
