Frequently Asked Questions
Q: What is the JT PT2748A-063 lock washer designed for?
A: The JT PT2748A-063 is a lock washer engineered for Jet A, L, and J manual pallet jack hydraulic units. It maintains secure fastener tension in high-vibration hydraulic subassemblies and is specified for OEM-designated locations in Jet pallet trucks.
Q: What material is this lock washer made from?
A: The JT PT2748A-063 is manufactured from medium carbon steel with spring temper processing. This material composition provides the spring force and resilience necessary to counteract vibration loosening in hydraulic assembly fasteners.
Q: Why is spring temper material critical for this application?
A: Spring temper medium carbon steel maintains constant clamping force under vibration. In hydraulic units, pump and cylinder operation create continuous vibration that loosens standard fasteners. The spring-tempered lock washer resists relaxation and preserves fastener preload over the life of the equipment.
Q: Can I reuse this lock washer if I remove and reinstall the fastener?
A: Lock washers lose spring temper properties with each removal and reinstallation cycle. If removed during maintenance, replace with a new JT PT2748A-063 washer to maintain the original clamping force specification and prevent hydraulic fluid leakage.
