Depressurization Valve Kit (Part #KVK043-4084) (OEM Part #219711)
Fig 1.
To replace this valve, remove lock nut from inside the lid with a 13mm spanner and lift out complete valve
(Fig.1). Replace the valve with new one. Ensure cutouts in the aluminium valve body fit into notches on top
handle.
Always replace the seal when refitting the valve. These locate the valve in position.
Tighten nut to 10Nm.
Circlip in valve handle.
To replace the circlip,
remove the decal and
push up the valve stem.
The circlip may now be
removed / replaced
PRESSURE INDICATOR:
To remove this indicator, locate M16 hexagonal nut in a socket and use the specified tool to undo the red cap.
(For tool kit see 6: Tools and Test Equipment).
GASKET OFFSET DEVICE:
The gasket offset device (GOD spring) is a very important safety device. It ensures that if the lid is incorrectly fitted pressure cannot build up.The spring is forced away from the gasket by the body lug as the lid is rotated. The
spring allows the gasket to seal when the lid and body lugs are in a half lug engagement or better interlock position.
Gasket Offset Device Cover (Part #KVC019-4055) (OEM Part #219577)
This device must be inspected monthly
To work correctly the spring must be firmly riveted to the lid. It must protrude on the inside of the lid, past the
flange by a minimum of 1mm (with gasket removed). See figures 3 and 4.
A new spring cannot be fitted without the correct factory equipment, spring and riveter.
If the spring or rivet is damaged a new lid must be fitted.
Procedure to correct GOD Spring setting
If the limits are outside the specification, then the GOD spring has to be adjusted using long nose pliers.

Ensure the lid is flat and stable and apply the pliers vertically. Locate the pliers onto the back edge of the spring
and twist inwards carefully. Do not buckle the spring. Check visually and measure the distance again.
Fig 4.
Remove the lid and gasket to ensure that the spring is protruding from the edge of the flange by 1 mm. (Fig. 5.).
