Wärtsilä W6L32 Spare Parts
Wärtsilä Vasa W6L32 four-stroke marine diesel engine.
Engine Specifications
Common Failure Areas & Applications
- Connecting Rod Big-End Bores: Fretting and distortion of the serrated mating surfaces. We strictly measure bore ovality; if out-of-roundness exceeds OEM limits, the rod requires re-machining to restore bearing crush.
- Exhaust Valve Seats (W32): Severe vanadium/sodium hot corrosion when operating on Heavy Fuel Oil (HFO). The Turnomat valve rotators must be inspected, as failure to rotate rapidly accelerates seat burnout.
- Injection Pump Plungers: Abrasive wear from catalytic fines (cat-fines) in poorly purified fuel, leading to internal leakage, retarded injection timing, and elevated exhaust gas temperatures.
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.
