SKF 1306 Instrucciones Para La Instalación

Installation instructions for SKF 1306, 1307 and 1308
rear wheel kits
To prevent oil leaks, always install new seal and sleeve whenever wheel is removed for any purpose.
Leave the sleeve inside the seal during seal installation to prevent seal spring "pop-out". Use appropriate seal installation tools or
equivalent to avoid damaging the seal. Do not strike the seal directly with a steel or brass hammer. If proper installation tools, or
equivalent, are not available, use a block of wood to protect the seal flange and case while striking with a soft faced hammer until
seal is completely seated into the bore.
Sleeve removal
1. Old wear sleeve must be removed by careful use of a rounded, blunt, cold chisel. Lightly tap with chisel, on two areas of the
sleeve, 90 degrees apart. If present, the flange of the wear sleeve must be cut with the chisel first. Caution: Do not scar the
shaft during the sleeve removal. It is not necessary to cut the sleeve completely through to remove it. Use the chisel to stretch
the steel enough to loosen it and then slip it off the axle.
2. Remove all dirt and oil from the sleeve seating area. Remove all nicks or burrs using proper methods to ensure axle remains
round.
3. If axle surface has damage such as, grooves or deep nicks from previous wear or repairs, smooth axle surface with proper
methods and apply a thin coat of non-hardening sealant or gasket making material prior to installing the new sleeve to prevent
oil leakage from between the sleeve and axle contact surfaces.
4. Before installing new sleeve, follow seal installation instructions, then continue to install new sleeve following steps 5 and 6.
5. Press new sleeve squarely into position. There is a .010" to .025" clearance required between the end of the wear sleeve and the
inner wheel bearing journal shoulder of the axle spindle.
6. Remove and clean away any excessive sealant left after the wear sleeve installation.
Seal installation
1. Remove all burrs or nicks from the hub bore and clean thoroughly.
2. Check hub cavity for appropriate amount of grease. Apply a small amount of the same grease on to the seal lip to avoid damaging
the seal during run in.
3. Press seal, with new wear sleeve still inside the seal to avoid spring pop-out, squarely into position using proper installation tools
and method. Do not cock the seal during installation. The seal flange should bottom squarely on to the hub surface.
4. Remove wear sleeve and check to ensure garter spring is in place. If spring has become dislodge, simple reinstall it into the
spring groove of the seal.
5. Install the new wear sleeve. Follow wear sleeve installation instructions on reverse side.
6. Care must be taken to prevent seal lip damage when assembling the hub and drum assembly over the wear sleeve on the axle
housing.
