WHEELS, RIMS AND TIRES2.Apply a thin coat of Loctite Gasket Eliminator(purple) hub seal bore. The coating must bevery light, yet cover the press fit area.3.To install unitized seal in wheel, seat outer faceof seal in the recess of tool adapter (Figure 23).Insert centering plug of tool in bore of innerbearing cone (Figure 24). Using the centeringplug aids in prevention of seal cocking in-wheelbore.Figure 23.Figure 24.4.Hold tool handle firmly and strike until sound ofimpact changes when seal is seated (Figure 25).Then inspect seal to be sure it is uniformlyseated but not crushed. Remove excesssealant.Figure 25.IMPORTANT Any time wheel Is removed witha Scot Unitized Seal for any purpose, the sealmust be replaced.A good check of proper seal installation is tomove the synthetic sealing member with yourfingers after installation in wheel hub. Thereshould be a slight in and out movement possible.If wheel seal parts requirements require a wiperring installation, refer to installation of wiper ringin preceding text.Unitized Barrier SealThe barrier type seal (Figure 18) is installed by hand andnew seals do not require any special lubricant or sealerto outer or inner surfaces, except when new sealappears to be free of lubricant. Then it is permissible towipe the leading edge of inside and outside diameterssparingly with light bearing oil. These seals do notrequire any special tools for installation.Position seal over hub and use care so that the seal isnot cocked when pushed into place.Push seal into the hub by hand until it is completelybottomed and uniformly seated in the bore.Do notuse wheel bearing or chassis grease to installseals, since grease could result in seal slipping in hub oron spindle or axle tube.CTS-4148APage 12
