Reassembly
1. Replace female gland on piston valve (13). Install
the five v-packings (4) one at a time with lips facing
up. Refer to the Packing Kits sections for the correct
packing order for your lower. Install the male gland.
NOTE:
To convert the lower to a different packing
material, see the Packing Kits sections. For best results,
soak leather packings in oil before reassembly.
2. Ensure there are no burrs or debris on mating
threads of displacement rod (1) and piston valve
(13). Apply anti-seize lubricant to threads and
mating surfaces of displacement rod and piston
valve.
3. Place flats of piston valve in a vise. Place piston ball
(12*) on piston valve.
4. Screw displacement rod (1) onto piston valve (13),
and hand tight. Then torque per table on page 13.
NOTE:
Position crowfoot of torque wrench at a 90°
angle to ensure accurate torque values.
5. To reinstall displacement rod (1) into lower cylinder
(11), first lubricate piston packings (4). Then, with
piston end facing down, lower rod into cylinder. Start
piston into cylinder as much as possible, then drive
rod and piston the rest of the way into the cylinder
with an arbor press or rubber mallet.

NOTICE
To reduce the possibility of costly damage to
displacement rod (1) and lower cylinder (11), first
place lower cylinder on a soft block of wood. Always
use a rubber mallet or an arbor press to drive the
displacement rod into the lower cylinder. Never use a
hammer to drive the rod.
