Piston & pin (.50mm)
Frequently Asked Questions
Q: What forklift models use the 91-754 piston and pin assembly?
A: The 91-754 piston and pin (.50mm) is compatible with hydraulic cylinders on Yale, Hyster, Clark, and CAT forklifts. Confirm your cylinder model and application before ordering.
Q: What are the specifications for the 91-754 piston and pin?
A: The 91-754 is a .50mm (12.7mm) piston and pin assembly. Verify bore diameter, rod diameter, and mounting orientation match your cylinder before ordering. Confirm pressure rating compatibility with your hydraulic system.
Q: What material is the 91-754 piston and pin made from?
A: The piston is typically cast iron or aluminum alloy with a hard-anodized or chrome-plated surface for wear resistance. The pin is hardened steel. These materials provide durability in high-pressure hydraulic applications.
Q: How long does a 91-754 piston and pin last in service?
A: Under normal operating conditions, pistons and pins typically last 3-5 years. Lifespan depends on hydraulic fluid condition, pressure cycling, contamination levels, and maintenance practices. Poor fluid quality or debris accelerates wear.
Q: What maintenance does the 91-754 piston and pin require?
A: Keep hydraulic fluid clean and at proper viscosity. Change fluid and filters per manufacturer recommendations. Monitor cylinder performance for signs of leakage, sluggish operation, or noise. Replace if internal seals fail or piston surfaces show scoring.
Q: Can the 91-754 be used in load-holding or tilt cylinders?
A: The 91-754 is designed for specific cylinder types. Verify compatibility with load-holding and tilt applications by matching bore diameter, rod size, and pressure rating. Mismatched pistons can cause leakage or premature seal failure.
