22. Apply clean hydraulic oil or Parker Super O-Ring
Lube (200006) to the head of the plunger. Turn the
plunger into the counter bore in the piston biscuit,
using a soft mallet if needed.
Make sure the T-seals do not get nicked or rolled.
23. Slide the spacer over the plunger with the large end
facing in as shown below. Install the snap ring into
the groove.
•
Repeat Steps 22 and 23 for the other plunger.
24. Apply clean hydraulic oil or Parker Super O-Ring
Lube (200006) to one seal and the inside of the
low-pressure cylinder. Install the seal onto the piston
with the flared (o-ring) face toward the outside of
the piston.
25. Slide the piston and plunger assembly containing
one seal into the cylinder oriented so that the empty
groove enters the cylinder first.
CAUTION
The seal is going into the cylinder against
the flare. Take care as the seal enters the
cylinder—it is compressed at this point and
can be easily damaged by rough handling.
26. Slide the piston into the cylinder until the empty seal
groove on the piston appears out of the other end of
the cylinder.
Note: If the seal starts to come out the end of the
cylinder, do not force it back in against the flare. In-
stead, push the whole piston assembly through and
start again, this time stopping before the seal
appears.
27. Apply clean hydraulic oil or Parker Super O-Ring
Lube to the seal and install it in the groove oriented
with the flared o-ring face toward the outside of the
piston.
