6.2.3 Replacing the Air vent assembly

Gain access to the internals by removal of the cover (

2

) by undoing the six ¾" UNF (

4

) nuts holding the 

cover in place.

Then remove the air vent assembly (

9

) and the air vent tube (

10

).

Put a little anti-seize on the thread of the new air vent assembly (

9

) together with the tube (

10

preassembled, tighten following the guidance of the torque setting in the table.

Note 1:

 The air vent tube must be aligned and pointing in the same direction as the directional arrow upon 

the seat clamp (

11

).

Note 2: 

when the internals have been assembled, with the pin (

13

) fully inserted so that it touches the air 

vent assembly it may appear long, do not cut it, it is purposely long to inhibit that with vibration its movement 

is limited, therefore, it is impossible for it to become free.

Parts drawn in a grey line are 

not supplied as spares.
