3. Use a spanner wrench installed in the holes pro-

vided. Unscrew the head (counterclockwise from the

ram end) (Fig. 0062).

4. Pull out the cylinder rod to remove the piston and

head assembly from the barrel (Fig. 0063).

INSPECT ROD: There should be no scratches or pits

deep enough to catch the ngernail. Pits that go

to the base metal are unacceptable. Scratches

that catch the ngernail but are not to the base

metal, 0.5” (1.27 cm) long and primarily in the

circumferential direction are acceptable provided

they cannot cut the rod seal. Chrome should be

present over the entire surface of the rod and the

lack thereof is unacceptable. In the event that an

unacceptable condition occurs, the cylinder should

be replaced.

INSPECT HEAD: Visually inspect the inside bore

for scratches or polishing. Deep scratches are

unacceptable. Polishing indicates uneven loading

and when this occurs, the bore should be checked

for out-of-roundness. If out-of-round exceeds 0.007”

(.18mm), this is unacceptable. Check the condition

of the dynamic seals, looking particularly for metallic

particles embedded in the piston seal surface.

Remove the seals. Damage to the seal grooves,

particularly on the sealing surfaces, is unacceptable.

In the event that an unacceptable condition occurs,

the cylinder should be replaced.
