## ⚙️ 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
