⚙️ Features

Direct OEM Replacement: Perfectly matches CFMoto OEM part numbers 0010-022500 / 152MI-022500.
Quality Material: Made from oil and heat resistant Viton or nitrile rubber, suitable for high-temperature engine environments.
Precision Molded: Precision molded sealing lips provide tight fit with valve stem, effectively controlling oil consumption.
Internal Spring: Some versions include an internal garter spring to maintain constant lip pressure on the valve stem.
Wide Application: Fits various CFMoto engine displacements from 125cc to 1000cc.

✅ Importance of Valve Stem Seal Replacement: Valve stem seals are critical components that prevent oil from entering the combustion chamber. Over time, rubber hardens and sealing lips wear, allowing oil to seep through the valve guide clearance into the combustion chamber, causing increased oil consumption, spark plug fouling, and blue smoke from exhaust. When replacing valves or performing engine overhaul, it is recommended to replace valve stem seals simultaneously to ensure proper engine operation.

📖 Installation Guide (Valve Stem Seals)

Follow these steps to replace the valve stem seals and ensure proper sealing and engine operation. This procedure requires specialized tools and is recommended to be performed by a professional technician.

🔧 Pre-Installation Preparation

Confirm the new valve stem seals are 0010-022500, 4pcs/Pack.
Prepare a valve stem seal installation tool, torque wrench, clean rags, and lubricant (engine oil).
Ensure the engine is cooled and remove the cylinder head and other necessary components to access the valve train.

🔄 Step 1: Remove the Old Valve Stem Seals

Using a specialized valve stem seal removal tool, carefully remove the old seals.
Take care not to scratch the valve guide inner wall.
Clean the valve guide mounting area, removing old seal residue and oil.
Inspect the valve stem and valve guide for wear — repair or replace if necessary.

🧽 Step 2: Install the New Valve Stem Seals

Remove the new seals (4 pieces) from their packaging and check for any damage or deformation.
Apply a small amount of clean engine oil to the valve stem for lubrication.
Slide the new seal onto the valve stem and use a specialized installation tool to press it onto the valve guide.
Ensure the seal is fully seated with the sealing lip facing the correct direction (typically toward the combustion chamber).
⚠️ Critical Step: Ensure the seal lip is not damaged by burrs or sharp edges on the valve stem during installation.

✅ Step 3: Post-Installation Check

Check that all seals are properly seated with no tilting or deformation.
Reinstall the cylinder head and other components according to factory specifications.
Start the engine and check for any unusual noises or smoke.
Take a test ride to confirm normal oil consumption.
Record the replacement mileage and date for future maintenance reference.

💡 Installation Key Points

Apply oil to the valve stem before installation to lubricate the seal and prevent dry-running damage to the lip.
Use a specialized installation tool — avoid pushing by hand to prevent seal deformation.
Pay attention to seal orientation — the sealing lip should face toward the combustion chamber.
It is recommended to inspect valve stem clearance and valve guide wear when replacing seals.
If you are not experienced with engine assembly, we strongly recommend professional installation.

⚠️ Verify Before Ordering: Please confirm your engine model is in the compatibility list. This is a valve stem seal set (4pcs/Pack). Each cylinder requires one intake and one exhaust seal. Apply a small amount of oil to the valve stem during installation and use a proper installation tool to avoid damaging the seal lip.
