Instruction Part Number 19512 Rev A

Instructions:

Valve can be repaired in place without

removal or disassembly. If assembly will

be serviced in place, turn off fuel tank

supply valve (or any others) to avoid fuel

spillage, then proceed as follows:

Prior to disassembly, note position

of item 2 (handle) in relation to valve

body for reassembly. All off position

recommended.

Remove items 1, 2, 3, 4, 5, and 6 in

order listed, note position of ﬂat on item

6 (stem).

Remove item 7 (O-ring) from item 5

(bonnet) being careful not to scratch

gland surface and discard. Lube new

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

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

instal in gland of item 5 (bonnet). Apply

1-2 drops of loctite #242 Threadlocker

(or equivalent) onto threads of item 5

(bonnet), then slide over item 6 (stem)

and thread into valve body. Torque item 5

(bonnet) to 33-50 foot pounds.

Place new item 4 (washer) over item 6

(stem) and into groove of item 5 (bonnet).

Thread item 3 (lock nut) onto item 6

(stem) ﬁnger tight only. Apply 1-2 drops of

Loctite #242 Threadlocker (or equivalent)

to thread between item 3 (lock nut) and

item 6 (stem).

Place item 2 (handle) onto item 6 (stem)

Note: Racor text faces outward toward

user. Apply 1-2 drops of Loctite #242

Threadlocker (or equivalent) onto threads

of item 1 (acorn nut) and install onto item

6 (stem). Torque item 1 (acorn nut) to 5-7

foot pounds, while securing item 3 (lock

nut) with a wrench.

Rotate valve handle and feel operation

through a full rotation. To increase

resistance, tighten item 3 (lock nut)

towards item 5 (bonnet). To reduce

resistance, loosen item 3 (lock nut) away

from item 5 (bonnet) (usualy 1/16 turn is

all that is needed). Repeat step 7.

Open any valves that were closed prior to

disassembly. Start the engine and check
