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.
