⚙️ Key Features

• Inlet valve spring
• 0.109 kg
• 32 applications across TAD, D and TWD series engines
• Supersedes 21326667

🔌 Function

Closes the inlet valve and keeps the valve gear in contact with its cam at speed.

⚠️ Common Signs of Failure

• Noise from the valve gear, particularly at higher speeds
• Misfire or loss of power as speed rises
• Spring broken, usually at an end coil
• Coils rusted, pitted or rubbing on one another
• Free length or squareness down when checked against a new spring

🛠️ Service Notes

• Fit inlet springs as a full set rather than singly, since the remainder of the same age will be close behind
• Check the valve, guide and seat while the head is apart, as a bounced or dropped valve damages more than the spring
• This is the inlet spring and should not be fitted in an exhaust position
