      Rebecca RushAug 6, 2025
      If your Hyundai Forklifts experiences oil leakage, it could be due to several reasons. The oil level might be too high, in which case you should lower it. Alternatively, the issue might stem from a broken or worn-out oil seal, a damaged packing case, or loose mounting bolts for the housing, all of which would necessitate replacement or retightening. A worn-out hub grease seal or a damaged bearing causing eccentric rotation could also be the cause, requiring replacement as well.

      Charles WestAug 20, 2025
      A continuous metallic groan in your Hyundai Forklifts could be caused by worn-out gears, which may require adjusting the backlash or replacing the gears. It may also happen because the pinion and bevel gear are meshed too deeply, indicating that you should refill. Other potential causes include a lack of gear oil (replace), a loose or worn-out bearing (adjust preload or replace), a loose bevel gear wheel (replace bolts and washers, then tighten), or a worn-out differential gear or thrust washer (replace).
