REASSEMBLY PROCEDURE

If the exhaust valve (129174) has been removed, pass

the valve tail through the case hole (129931 or 129932),

from outside and pull gently until the notch is inside the

case. If it is a new exhaust valve, one installed, cut off any

excess tail leaving about 5mm.

Place the exhaust tee

(129908) on both case

notches

(129931

low part to clip it.

Fit a new O-ring (AP2041) in the shuttle valve groove

(AP2036). Insert a new rubber seating (129638) in the

shuttle valve. With a brush, lubricate the shuttle valve tail

(O-ring side).

Insert the spring (AP2021) in the counter balance cylinder

(129784). Guide carefully the shuttle valve tail (AP2036)

cylinder.

If the lever (129178) has

been removed, place it again,

take care to install it at the

same side as the valve

spindle punch (129146).
