Using this HPT Modified K - series Crank Timing Gear is straightforward. First, make sure to check the fitment with us if you're not certain. Once you have the right fit, you'll need to file it for proper installation because the clearances are tight. When installing, pay attention to the solid metal key - way that locks the timing gear and pulse plate in place. As for maintenance, keep it clean from dirt and debris. Regularly check if the key - way and the locking mechanism are in good condition. If you notice any signs of wear or looseness, contact us right away. Remember, this product is made for most Honda/Acura K Series Engines, but always double - check fitment before you start the installation.
