Frequently Asked Questions
Q: What are the dimensional specifications for the JT PT2748A-089 E-ring?
A: The JT PT2748A-089 is an external retaining ring (E-ring) designed for 8 mm shaft retention. External diameter is 14 mm. The ring is manufactured from spring steel conforming to ASTM A228 specification with Rockwell C41-50 hardness. Finish is plain, uncoated steel.
Q: Which Jet pallet jack models use the PT2748A-089 E-ring?
A: The JT PT2748A-089 fits Jet manual pallet jack models PT2748A, PT2748J, and PT2748L. It serves as a shaft retaining clip in the hydraulic or mechanical lift assembly. Verify your equipment model plate matches before ordering.
Q: What material is the JT PT2748A-089 made from and how long does it last?
A: The JT PT2748A-089 is manufactured from spring steel per ASTM A228 specification, hardened to Rockwell C41-50. This hardness provides corrosion resistance and elastic retention force. Under normal operation, E-rings last the life of the equipment unless bent, deformed, or lost. Replace if the ring loses elastic tension or shows visible damage.
Q: Is there a cross-reference or equivalent part for the PT2748A-089?
A: No known cross-references or equivalent parts from other manufacturers are documented for the JT PT2748A-089. This is an OEM Jet part with no published interchangeable alternatives. Order the exact part number to ensure correct fit and function.
Q: What happens if the PT2748A-089 E-ring becomes loose or falls off?
A: If the E-ring is missing or loose, the shaft component it secures may shift or separate during operation, causing lift failure or unsafe condition. Replace the ring immediately if you detect movement or loss of the retaining clip. Do not operate equipment with a missing shaft retainer.
Q: Does the JT PT2748A-089 require any maintenance or lubrication?
A: The E-ring itself requires no maintenance. However, the shaft it retains should be kept clean and properly lubricated per Jet maintenance guidelines. Contamination or corrosion of the shaft can impair the ring fit and reduce retention force.
