- Do not use impact tools with this installer kit, as it can damage the tool or the engine components.
- Keep the work area clean and well-lit.
4. Setup
4.1. Identifying the Correct Threaded Rod
Before starting, identify the correct threaded rod for your vehicle's crankshaft. Refer to the compatibility list below:
| Thread Size | Compatible Vehicles |
|---|---|
| M16 x 2.0 | General Motors (GM) |
| M14 x 1.5 | Dodge, Chrysler, Jeep |
| M12 x 1.75 | Dodge, Chrysler, Jeep |
| M12 x 1.5 | Ford |
4.2. Preparing the Engine
- Ensure the crankshaft is free of any scratches or burrs. Clean the crank and the keyway thoroughly.
- Apply a light coat of clean engine oil to the crankshaft and the keyway.
- Verify that any existing key is properly seated in the hub of the harmonic balancer/pulley.
5. Operating Instructions
Follow these steps carefully to install the harmonic balancer or pulley using the OEMTOOLS 27306 kit:
- Select the appropriate threaded rod for your engine application (refer to Section 4.1).
- Thread the selected rod into the crankshaft by hand. Ensure it is properly seated and threads smoothly. Do not force it.
- Place the forcing nut with the thrust bearing assembly onto the threaded rod. The bearing should face away from the harmonic balancer/pulley.
- Thread the forcing nut onto the threaded rod and screw it into the end of the crankshaft.
- Using a wrench, hold the hex end of the threaded rod stationary.
- Using a second wrench, turn the forcing nut clockwise. Continue turning until the harmonic balancer/pulley is fully installed and seated against the crankshaft.
- Once the balancer/pulley is installed, remove the installer by turning the forcing nut counter-clockwise until the threaded rod is free.
- Finally, remove the threaded rod from the crankshaft.
Note: Do not attempt to press the balancer/pulley onto the crank without the keyway properly in place. If you encounter resistance or are unable to smoothly install the balancer/pulley, re-check the keyway for proper alignment and ensure the crankshaft threads are clean and undamaged.

6. Maintenance
Proper maintenance will extend the life and performance of your OEMTOOLS 27306 kit.
- Cleaning: After each use, wipe all components clean of oil, grease, and debris.
- Lubrication: Periodically apply a light coat of oil to the threaded rods and the forcing nut threads to ensure smooth operation and prevent corrosion.
- Storage: Always store the kit in its original sturdy, organized case in a dry environment to protect components from damage and corrosion.
- Inspection: Before each use, inspect all components for signs of wear, damage, or deformation. Do not use damaged tools.

7. Troubleshooting
If you encounter issues while using the harmonic balancer/pulley installer, consider the following:
- Difficulty Threading Rod: Ensure you have selected the correct threaded rod for your engine's crankshaft. Check the crankshaft threads for damage or debris. Clean and lubricate threads if necessary.
- Balancer/Pulley Not Seating: Verify that the keyway on the crankshaft and the balancer/pulley are perfectly aligned. Do not force the balancer/pulley; misalignment can cause damage. Check for any obstructions behind the balancer/pulley.
- Excessive Resistance During Installation: Ensure the thrust bearing is properly positioned with the bearing surface facing away from the balancer/pulley. Lubricate the threads of the forcing nut and threaded rod. If resistance persists, re-check for proper alignment and correct rod selection.
- Tool Damage: If any component of the kit appears damaged or bent, discontinue use immediately to prevent further damage to the tool or engine. Contact customer support for assistance.
