Frequently Asked Questions
Q: How does SU S866 differ from SU S865 in specifications?
A: SU S866 is a medium-duty variant with a wider hub flange and reinforced wheel rim. While axle diameter matches S865 at 1 inch, S866 is rated 500 lb higher at 5000 lb per wheel. S866 is optimized for mixed-terrain and outdoor warehouse use.
Q: What lift truck models use SU S866 wheels as OEM equipment?
A: SU S866 is standard on Nissan 1F4-1F5 series, Crown 5G-series, and Hyster H60 forklifts. Cross-reference your truck model and serial number before ordering. If your truck originally shipped with pneumatic tires, verify that the rim width and bolt pattern match before installation.
Q: What tire and load specifications apply to SU S866?
A: SU S866 uses a 6.00-9 pneumatic tire and is rated 5000 lb static load. Maximum dynamic load during rapid cornering is 6500 lb for short duration only. Always stay within rated load limits to prevent tire failure and loss of vehicle control.
Q: Can SU S866 be retrofit onto a truck that originally had SU S855?
A: No. S866 and S855 have completely different axle diameters and hub geometries. The 1 inch versus 1.25 inch axle diameter mismatch is not interchangeable. Attempting this modification causes binding and bearing damage. Order the correct wheel for your truck axle size.
Q: What is the proper torque specification for SU S866 hub bolts?
A: Torque all hub bolts to 40 ft-lbs using a calibrated wrench. Do not over-torque beyond 45 ft-lbs as this can crack the hub casting. Re-check bolt torque after the first 25 operating hours and then every 500 hours or monthly. Loose wheels cause erratic steering and tire wear.
Q: What is the expected service life and replacement cost for SU S866?
A: Under normal warehouse duty, SU S866 wheels last 18 to 24 months before replacement. Outdoor and rough-surface use reduces life to 12 to 16 months. Order complete wheel-and-tire assemblies for consistency. Individual wheel replacement without tire service may cause vibration and uneven wear on other axles.
