How to fix oil leakage in Nabtesco Engine?
- Ssydney38Aug 14, 2025
If you notice oil leakage from the mating surfaces of your Nabtesco Engine, try polishing the surface with a grindstone or polishing paper. For looseness of bolts either from the case or from the hydraulic motor, retighten them. If the leakage is from the floating seal, wash away any earth and sand. If you see cracks with stones, wear of sliding surfaces, or O-ring creep, replace the GM. For O-ring damage, replace the O-rings. If there are scratches on the sealing surface, polish the surface using a grindstone or polishing paper.
