The "plus" in Chicago Rawhide Scotseal Plus could be said to stand for "easy installation." Because, while the Scotseal Plus design has many new features, the most significant feature for the truck owner or fleet operator is the fact that it can be installed by hand -- that is, without special tools.

That's important for two reasons: 1.) Most early seal failures can be traced directly back to an installation error, and 2.) The leading cause of installation problems can be attributed to misusing or -- more often -- not using the proper installation tool. By eliminating the need for any special tools, the Scotseal Plus makes good installation possible even under bad conditions.

The Scotseal® Plus is hand installable. No special tools are required. Caution: Do not install the Scotseal® Plus directly onto the spindle.

• Place the hub (wheel) assembly flat or least 45° angle for seal installation.
• Pre-lube the inner bearing cone with the lubricant that is being retained and place it into the hub.
• Lightly lubricate the seal O.D. and I.D. evenly with the fluid that is being retained. Also apply a thin layer of oil on the hub bore that the seal is being pressed into. NEVER INSTALL DRY.
• Press the seal by hand evenly into the bore. A rubber mallet or other soft-faced tool may be used to gently tap the seal into place. Be sure that the seal is evenly seated and bottomed in the bore. As in any seal installation, apply an even driving force to avoid cocking the seal or damaging the flange surface.

Caution: Install a new seal if the seal is cocked or damaged during or after installation.
