Valve cotter suitable for JCB DieselMax / EcoMax - Engine

Part Number: 320/03528
Type: Valve Cotter / Taper Lock
Engines: JCB DieselMax / EcoMax (444, 448)
Manufacturer: Aftermarket

Function and failure diagnostics

The 320/03528 valve cotter is a small, two-piece tapered component that holds the valve spring under tension, allowing the valve to close properly after opening.

Critical failure:

  • Usually shows no early warning signs.

  • Sudden breakage or ejection leads to severe engine damage.

Causes of failure:

  • Engine overspeed (exceeding allowed RPM)

  • Broken valve spring

  • Incorrect installation

Signs of wear:

  • Worn grooves on the cotter or valve stem, visible during cylinder head overhaul.

⚠️ Safety warning
Incorrect installation or a damaged valve cotter can release the spring, causing the valve to drop into the cylinder and completely destroy the engine (piston, head, cylinder). Always ensure cotters are properly seated during assembly.
