Precautions for Using Floating Seal Extract:
1. In general, replace the floating seal with a new one after disassembling. If the floating seal is required to be reused, follow these procedures:
– Keep seal rings together as a matched set with seal ring (1) surfaces together. Apply oil onto sliding surface (e) of seal ring (1).
– Check sliding surface (e) of seal ring (1) for scuffing, scoring, corrosion, deformation, or uneven wear. Check the step part of seal ring (1).
– Check O-ring (2) for tears, breaks, deformation, or hardening.

2. If incorrectly assembled, oil leakage or damage will occur. Be sure to do the following to prevent trouble.
– Clean the floating seal and seal mounting bores with cleaning solvent.
Use a wire brush to remove mud, rust, or dirt from seal mounting bores. After cleaning, thoroughly dry
parts with compressed air.
– Clean seal ring (1) and O-ring (2) mounting bores.
Check the bore surface for scuffing or scoring by touching the surface with finger.
– After installing the floating seal, check that O-ring (2) is not twisted, and that it is installed correctly on seal ring (1).
– After installing the floating seal, check that O-ring (2) and seal ring sliding surface (e) is parallel with seal mating surface (f ) by measuring the distances (e) and (f ) at point (A) and (B), as illustrated. If these distances differ, correct O-ring (2) seating
