Sealey Harmonic Balancer Puller Set 49pc - PS979

The yoke has a size spread of 40mm to 93mm, meaning it can grip components within this diameter range.

The set includes a comprehensive range of common SAE and metric bolts. While it covers many applications, it's always best to verify the specific thread size and pitch for your vehicle against the included hardware list.

While primarily designed for harmonic balancers and flywheels, the tool's design with a yoke and puller bolts allows it to be adapted for removing other press-fit components within its size and strength capabilities, provided appropriate bolts can be used.

It is recommended to lightly oil the threads of the 130mm thrust bolt and any other metal components after cleaning to prevent rust and ensure smooth operation for future use.

The total weight of the Sealey Harmonic Balancer Puller Set (PS979) is 2.14kg.

When attaching bolts to the component, ensure they are snug. When using the thrust bolt, tighten it gradually and evenly. If using multiple bolts on the yoke, ensure they are all equally tightened against the component before applying primary pulling force with the thrust bolt.

Ensure you are using the correct size and thread pitch bolts that are fully seated in the component. Check that the yoke is securely fastened to the bolts and that the thrust bolt is correctly centered.

Verify that the thrust bolt is threaded properly into the crankshaft (if applicable) or center hole. Ensure the component is not excessively seized. You may need to apply penetrating oil and allow it time to work, or use a hammer to gently tap the yoke (not the crankshaft) to help break the bond.

Confirm you are using the correct thread pitch. Do not overtighten bolts into the component before applying pulling force. If the threads are damaged, a replacement bolt may be needed.

Ensure the pulling force is distributed evenly. If the component is extremely seized, consider using a hydraulic puller or seeking professional assistance to avoid tool damage.
