📌 Linhai Compatibility Note: These intake/exhaust valves are suitable for the Linhai ATV / UTV models listed above. Intake valve corresponds to Linhai part number 35135 / 1BE-12111-00, exhaust valve corresponds to Linhai part number 35141 / 1BE-12121-00.

🔧 Pre-Installation Preparation

• Confirm the new valves are Intake (0180-022004, 2pcs) and Exhaust (0180-022005, 2pcs).
• Prepare a valve spring compressor tool, valve grinding tools, torque wrench, clean rags, and lubricating oil.
• Ensure the engine is cooled and remove the cylinder head to access the valve train.

🔄 Step 1: Remove the Old Valves

• Using a valve spring compressor tool, compress the valve spring.
• Remove the valve keepers (valve locks) and carefully release the spring tension.
• Remove the old valves from the bottom of the cylinder head, distinguishing between intake and exhaust valves.
• Inspect the valve guides for wear — replace if necessary.
• Clean the cylinder head valve seat area, removing carbon deposits and old seal residue.

🔧 Step 2: Lap the Valve Seats (Recommended)

• Apply a small amount of valve lapping compound to the valve sealing face.
• Insert the valve into the valve guide and use a lapping tool to rotate the valve back and forth against the seat.
• Periodically check the sealing face until a uniform gray sealing band is achieved.
• Thoroughly clean the valve and valve seat, removing all lapping compound residue.
• ⚠️ Critical Step: Ensure the sealing surfaces are completely clean — residual lapping compound will cause poor sealing.

🧽 Step 3: Install the New Valves

• Remove the new valves from their packaging and apply a small amount of oil to the valve stems for lubrication.
• Install the intake valve (0180-022004) on the intake side and the exhaust valve (0180-022005) on the exhaust side.
• Install the valve springs and valve keepers.
• Use a valve spring compressor tool to install the keepers, ensuring they are fully seated in the valve stem grooves.
• After installation, manually rotate the valves to confirm smooth rotation with no binding.

✅ Step 4: Post-Installation Check

• Reinstall the cylinder head and other components according to factory specifications.
• Adjust valve clearance to the standard values specified in the service manual.
• Start the engine and check for any unusual noises or rough running.
• Take a test ride to confirm restored engine power and smooth operation.
• Record the replacement mileage and date for future maintenance reference.

💡 Installation Key Points

• It is recommended to replace valve stem seals and guides simultaneously when replacing valves.
• Always lap the valve seats before installation to ensure proper sealing.
• Pay attention to intake/exhaust valve distinction — do not mix them up.
• Valve clearance must be adjusted to specification after installation.
• If you are not experienced with engine assembly, we strongly recommend professional installation.
