Floating Oil Seal AppliC-A-Tion:
- Excavator, bulldozer, tractor, cranes, forklift, Heavy truck, backhoe
- Undercarriage, hydraulic motor, travel motor, gearbox axle, wheel hub,tunneling
Method of installation:
1. Using specialized tools installation: The pressure will apply to the O-ring directly. As shown, the special tool is mounted between the metal floating ring and the rubber ring, toward the seat hole, the rubber ring is evenly pressed into the hole.
2. Other installation methods: One auxiliary O-ring is fixed between the conical ring surface of the floating oil seal and sealing O-ring (as shown). The ring of the floating oil seal is applied uniformly by pressure and the auxiliary O-ring braces the sealing O-ring to ensure the other correct mounting positions.
