Using this lower timing chain guide is straightforward. First, remove the old OEM lower chain guide carefully. Then, install the Circuit Hero guide in its place. Make sure it's properly aligned with the crank pulley chain gear. When performing a camshaft swap, double - check that the chain is securely in place on the gear. As for maintenance, it's a good idea to inspect the guide regularly for any signs of wear and tear. If you notice any cracks or excessive damage, replace it right away. Keep it clean to ensure optimal performance.
