Do you need to replace the cylinder seal kits?
Hydraulic oil leaks in excavators can cause weak digging and slow operation. Look for oil stains or dust on the cylinder rod, which may indicate a leak or bad seal. Ignoring leaks can contaminate the hydraulic system and lead to expensive repairs. Fix leaks quickly and replace seal kits if needed. When replacing, use the correct part number, carefully disconnect hoses, and check all parts. If unsure, get professional help. Common leak causes include worn seals, damaged rods, and wrong hydraulic fluid.
