26. Lubricate the new T-seals and backup rings with
Parker O-Ring Lube (200006). Place two backup
rings and one T-seal in each piston groove. The must
be in the middle of the two backup rings.
27. Apply clean hydraulic oil or Parker Super O-Ring
Lube to the head of the plunger. Insert the plunger
into the counter bore in the piston, using a soft mal-
let if needed. Make sure the T-seals do not get
nicked or rolled.
Slide the spacer over the plunger with the large end
facing in. Install the snap ring into the groove.
28. Repeat Steps 23–27 for the other plunger.
Low-pressure cylinder
29. Apply clean hydraulic oil or Parker Super O-Ring
Lube to one new 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.
30. Slide the piston and plunger assembly containing one
seal into the cylinder so that the empty groove enters
the cylinder first. Use a soft-faced mallet where nec-
essary.
CAUTION
Take care when the seal enters the cylinder.
It is compressed at this point and can easily
be damaged by rough handling.
