Product Description

Installation Notice Remind

• Torque Specifications: Always use a torque wrench to tighten bolts. Over-tightening can cause component damage, such as cracking the cylinder head, while under-tightening may lead to leaks. Refer to the engine's official manual for the correct torque values for each bolt.
• Cleanliness: Keep the work area and all parts clean. Even a small particle of dirt can cause significant damage when trapped between moving components. Wipe down parts with clean rags before installation and use clean tools.
• Lubrication: Adequately lubricate all moving parts during installation. This includes applying engine oil to piston rings, bearings, and camshaft lobes. Lack of proper lubrication can result in premature wear during the engine's initial start-up.
• Alignment: Ensure proper alignment of components like the crankshaft and camshaft. Incorrect alignment can disrupt the engine's timing, leading to poor performance or even engine failure. Use alignment tools if available.
• Electrical Safety: If disconnecting any electrical components, ensure the engine is off and the battery is disconnected. When reconnecting, double-check all connections to avoid short circuits.
