d.
Torque the Piston nut as specified in Table 5-4, Pis-
ton Nut Torque. Lack of the torque can result in
internal leakage, the piston coming unscrewed, and
thread damage. If overtorqued, the piston surface
which meets the rod will be damaged.
5.
Assemble the rod assembly.
a.
Secure the barrel at a vertical or horizontal position.
b.
Insert the assembly into the barrel.
c.
When piston is inserted to the barrel take care as to
not damage the seal rings.
6.
Gland assembly.
Install the gland using a spanner wrench as shown
below.
7.
Caulking.
Caulk at the machined area of the cylinder barrel end so
that it locks the cylinder head in place and it does not
unscrew from the barrel. If there is no caulking hole,
caulking is not necessary.
8.
Test operation.
a.
Install the cylinder on a machine. Fill the cylinder
with oil and then have the cylinder slowly operated
a minimum of 8 cycles. If it is operated too fast in the
beginning, cavitation will result. It is important to
make sure all air is cycled from the cylinder.
b.
Grease the end of the pin.
