Frequently Asked Questions
Q: What forklift models require the 91-FE3 piston and pin?
A: The 91-FE3 piston and pin (.50mm) fits Jungheinrich, Linde, BT, and Mitsubishi forklifts with compatible lift and tilt cylinders. Confirm your equipment series and cylinder bore size before ordering.
Q: What is the bore diameter specification for the 91-FE3?
A: The 91-FE3 has a .50mm piston bore. Verify your cylinder bore matches exactly. Even minor dimensional differences will prevent proper sealing and cause leakage.
Q: What pressure rating does the 91-FE3 piston and pin support?
A: The 91-FE3 is designed for standard forklift hydraulic pressure ranges of 150-210 bar. Confirm your system pressure does not exceed maximum ratings. Over-pressure operations cause seal failure and internal damage.
Q: How long does the 91-FE3 piston typically remain in service?
A: Under proper maintenance, the 91-FE3 lasts 3-5 years or 4000-6000 operating hours. Lifespan is shortened by dirty hydraulic fluid, contamination, extreme temperatures, and high cycle rates. Replace sooner if performance degrades.
Q: What maintenance prevents premature 91-FE3 piston failure?
A: Maintain clean hydraulic fluid with proper ISO 4406 cleanliness levels. Change filters and fluid per manufacturer intervals. Monitor cylinders for leakage and sluggish operation. Inspect piston rod surface for rust or scoring and address immediately.
Q: Are there equivalent cross-reference parts for the 91-FE3?
A: Contact us with your OEM part number and cylinder specifications. We can confirm direct cross-references and ensure the 91-FE3 is the correct match for your equipment.
