Using this engine mount is easy. First, make sure your frame rails are 92 x 28mm as this mount is designed for them. Place the mount flat on the frame rails and use the one - hole clamp style to secure it. Then, align the engine with the bolt pattern of 4 inches long and 3 1/8 inches wide (102mm x 80mm) and bolt it on. When it comes to maintenance, regularly check the bolts to ensure they are tight. If you notice any signs of wear or damage, replace the mount right away. Keep it clean from dirt and debris to extend its lifespan. It's suitable for IAME Swift and Mini Rok engines, so always double - check compatibility before installation.
