Frequently Asked Questions
Q: What does the .50mm designation mean for the YL 9012938-43 piston and pin?
A: The .50mm specification indicates this piston and pin assembly is sized .50mm oversize. This is an oversized replacement component used when standard-size pistons have worn beyond limits and bore reboring is required.
Q: Which Yale lift truck engine models use the YL 9012938-43 piston and pin?
A: The YL 9012938-43 piston and pin fit specific Yale electric lift truck engine models. Verify your engine model, displacement, and cylinder bore size before ordering, as this .50mm oversized component requires matching bore preparation.
Q: What material is the YL 9012938-43 piston made from?
A: The YL 9012938-43 piston is typically cast aluminum alloy designed for high-temperature operation in lift truck engines. The pin is steel or alloy steel for durability and load bearing.
Q: Can the YL 9012938-43 piston and pin be used as a direct replacement for standard-size pistons?
A: No. The .50mm oversized specification means the cylinder bore must be rebored to .50mm oversize to accommodate this piston and pin. Standard bore cylinders cannot use this component without proper machining.
Q: What is the service life of the YL 9012938-43 piston and pin assembly?
A: Piston and pin lifespan depends on engine operating conditions, maintenance, and fuel quality. Replace if you notice excessive blow-by, loss of compression, or visible carbon buildup. Typical overhaul intervals range from 5-10 years depending on usage.
