Precautions: Using Floating Seal Manual Instructions

Follow these guidelines when handling floating seals:

1. After disassembling, replace the floating seal with a new one. If reusing, ensure the following:
   • Keep seal rings as matched sets with surfaces together. Apply oil to the seal ring’s sliding surface.
   • Inspect the seal ring for scuffs, scores, corrosion, or uneven wear.
   • Examine the O-ring for tears, breaks, deformations, or hardening.
2. Prevent issues by ensuring correct assembly to avoid oil leakage or damage.
   • Clean the floating seal and mounting bores with a detergent solvent, and thoroughly dry them with compressed air.
   • Verify the seal ring and O-ring mounting bores for any surface damage.
   • Upon installation, ensure the O-ring is correctly seated and not twisted regarding the seal ring.
   • Ensure the seal ring’s sliding surface is parallel to the seal mating surface. Adjust the O-ring as needed if discrepancies are found.
