10. Clean all sealant from the threads of any part being
reused and apply thread sealant to the first two or
three internal threads of the valve assembly (44).
If
you removed the capscrew (31a)
, apply primer to
its external threads, let it dry for four minutes and
torque the cap screw to 42-45 in-lb (4.7-5.1 N.m).
Remove excess sealant. Allow 24 hours for the
thread sealant to cure before you operate the recip-
rocator.
11. Use a spanner wrench to screw the piston (35) onto
the displacement rod (54). Torque to 30-40 ft-lb
(41-54 N.m).
12. Install the o-ring (18) in the deep lower groove of the
piston (35) and install the seal (38) over the o-ring.
Install the piston bearing (37) around the upper
groove of the piston. Holding the piston bearing in
place to avoid damage, slide the cylinder over the
piston and press it down.
NOTICE
When inserting the piston into the cylinder, carefully
guide the piston seal (38) and bearing (37) to prevent
damaging these parts.
