Popular Wärtsilä Components We Supply
Technical Specifications & Coverage
Engine Model Coverage
We focus heavily on the widely utilized Wärtsilä Vasa 32, L20, W32, W38, and W46 series 4-stroke medium-speed engines, commonly deployed for both main propulsion and diesel-electric generator configurations.
Commonly Replaced Components
Rocker arm assemblies, pushrods, valve rotators, injection valve nozzles, and complete connecting rod assemblies are standard fast-moving spares in our Wärtsilä inventory.
Known Failure Areas
Wärtsilä engines often require careful monitoring of the big end connecting rod bearings for fretting, and the exhaust valve seats for high-temperature vanadium/sodium corrosion, particularly when operating on heavy fuel oil (HFO).
Inspection Process
Cylinder heads are stripped, chemically cleaned, and subjected to a 7-bar pneumatic leakage test on the valve seats. We also check the dimensional concentricity of connecting rod big-end bores to prevent bearing crush issues.
Frequently Asked Questions
Can you supply complete cylinder heads for Wärtsilä 32 engines?
+
Yes. Reconditioned Wärtsilä 32 cylinder heads are supplied complete with valves, springs, rotators, and indicator cocks. The valve seats are ground and lapped, and the cooling spaces are pressure-tested.
Do you supply fuel injection pump plungers for Wärtsilä L20 auxiliary engines?
+
Yes, we stock both complete fuel injection pump assemblies and individual plunger/barrel elements for the Wärtsilä L20 series, ensuring precise fuel delivery timing and atomization.
Are connecting rod serrations inspected on Wärtsilä W46 engines?
+
Absolutely. The serrated mating surfaces of W46 connecting rod big ends are visually inspected under magnification and dye-penetrant tested to ensure there are no stress fractures or fretting wear.
Do you stock valve rotators (Turnomats) for Wärtsilä engines?
+
Yes, we stock genuine used Turnomat valve rotators for Wärtsilä 32 and 46 engines. Proper rotation is critical to prevent localized heat buildup and premature exhaust valve failure.
