Silver Seal Harmonic Balancer Repair Sleeve

The Silver Seal Harmonic Balancer Repair Sleeve line is made to repair a worn sealing surface on a harmonic balancer (vibration damper) hub. Over time, the front crankshaft or timing cover seal can wear a groove into the balancer hub. Even a new seal can then leak oil. This repair sleeve gives the seal a fresh surface to run against, so you can often fix the leak without buying a new balancer.

Key Features:

• Restores the sealing surface on a harmonic balancer hub that has grooves, nicks or wear
• Part of the Silver Seal MicroSleeve repair sleeve range, which is designed for engine rebuilding and repair
• Press-fit installation over the worn seal area of the balancer hub
• Helps stop front crankshaft seal oil leaks caused by a worn hub
• Cost-effective alternative to replacing a balancer that is otherwise in good condition
• Available in a range of sizes to suit different balancer hub dimensions

Installation Notes: Clean rust and dirt from the hub seal surface before installing. The sleeve should be pressed or driven on squarely. Silver Seal offers matching harmonic balancer sleeve installation tools for this. A repair sleeve slightly increases the diameter of the sealing surface, so choose a front crankshaft seal that suits the sleeved diameter.

Also known as a harmonic balancer seal repair sleeve, vibration damper repair sleeve or crankshaft pulley seal surface sleeve. It is a practical fix for oil leaks at the front crankshaft seal when the balancer itself is still serviceable.
