GENERAL / Precautions for Disassembling and Assembling Floating Seal Precautions 1. In general, replace the floating seal with a new one after disassembling. If the floating seal is to be reused, follow these procedures: (1) Keep seal rings together as a matched set with seal ring faces together. Insert a piece of cardboard to protect surfaces. (2) Check sliding surface (C) on seal ring (A) for scuffing, scoring, corrosion, deformation or uneven wear. (3) Check O-ring (B) 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.
(1) Clean the floating seal and seal mounting bores with cleaning solvent. Use a wire brush to remove mud, rust or dirt. After cleaning, thoroughly dry parts with compressed air. (2) Clean the floating seal and seal mounting bores. Check the bore surface for scuffing or scoring by touching the surface with touch. (3) Check that O-ring (B) is not twisted, and that it is installed correctly on seal ring (A). (4) After installing the floating seal, check that seal ring surface (C) is parallel with seal mating face (D) by measuring the distances (C) and (D) at point (a) and (b), as illustrated. If these distances differ, correct O-ring (B) seating.
