Instructions:
Valve can be repaired in place without

be serviced in place, turn off fuel tank

Remove item 7 (O-ring) from item 5

item 7 (O-ring) with Parker Super O-lube
(or equivalent) and install into inside grove
of item 5 (bonnet).
Lube item 8 (O-ring) and install new item
4.
6 (stem) into valve body ensuring that
bottom tab properly engages slot in ball
as shown, and flat on top of stem is in
correct position as noted in step 2 above
-this is very important.
Lube item 9 (bonnet to body O-ring) and
5.
instal in gland of item 5 (bonnet). Apply
1-2 drops of loctite #242 Threadlocker
(or equivalent) onto threads of item 5

(bonnet) to 33-50 foot pounds.
Place new item 4 (washer) over item 6

resistance, loosen item 3 (lock nut) away
from item 5 (bonnet) (usualy 1/16 turn is
all that is needed). Repeat step 7.
