• ALWAYS read and understand your machinery’s specific safety warnings and instructions before
using this kit. Use the correct fluids, pressures, adapters, etc., for your machinery. Make sure the
machinery is fully supported and parked before beginning any work. Take care to NEVER touch
any heated surface with exposed skin.
• Before servicing your machinery, turn off its engine and refer to its manufacturer’s service and
repair manual for instructions on safely securing the machinery with chocks, jacks, stands, etc.

readily available. Know the location of emergency medical facilities.
• Machinery repair is an inherently dangerous activity. This manual and the separate machinery
service manual cannot cover all possible situations that may arise. ALWAYS exercise discretion
and good judgment. Seek training if needed.
• For best results, keep the kit clean and dry. Remove any fluid, oil, or grease before and after work.
• Dress appropriately for automotive servicing. DO NOT wear loose clothing or jewelry, and keep
hair, clothing, gloves, hoses, and tools away from any moving parts during use.
• If a component is particularly stubborn, avoid applying excessive force that could damage the puller
or the workpiece. Instead, apply penetrating oil, allow it time to work, and proceed with gradual
force application.

Operation
• Shut the engine before servicing, make sure the vehicle is in a stationary state for easy
maintenance, and that the engine has cooled to room temperature before performing
maintenance or adjustments.
• Use correct tools and personal protective equipment (PPE) before performing any
operation. Be extremely careful with possible pinching points, moving parts, or parts that
may suddenly spring out.
• Make sure your surroundings are safe for using the tool. Avoid operating in crowded or
unstable areas.
• Make sure the work area is clean and clear of any clutter or dirt that may affect
operations.
• ALWAYS ensure that your vehicle has been jacked up and is adequately supported with
axle stands.
• Do not force the tool. Excessive force may cause serious personal injuries and severe
property damage.
• For an abundance of safety, we recommend you take training before using these tools.
Serious injury could happen due to a lack of training.
1. Match the slots on the yoke (Part 11) to the holes in the harmonic balancer to determine the
number of bolts needed.
2. Find the set of bolts that fit the threaded holes in the harmonic balancer.
3. Thread the bolts with washers through the slots in the yoke and into the holes in the harmonic
balancer.
4. Grease the black pressure screw (Part 8). Thread this through the hole in the center of the
yoke.
5. Place the centering adaptor (Parts 9 or 10) or tip the assembly onto the end of pressure screw
and thread the screw against the crankshaft surface.
