Remove the piston rod.
Make sure that the piping ports are opened.
Catch the oil coming out from the rod side (cylinder
head side) port.
With the piston rod extended fully, remove the cylinder
head carefully.
Lay down the piston rod and the cylinder head together
on wood blocks.
Note:
Once all the bolts are removed, do not lift the piston
rod, as the cylinder may fall suddenly when separating.

When pulling out the piston rod from a horizontally
positioned ram, be careful to prevent the rod from falling
just after it leaves the cylinder. During removal of the
piston rod, support it horizontally on blocks.
5
Secure the piston rod.
Use the flat rod head or the rod end eye to prevent the
piston rod from rotating.
6
Remove the piston nut.
Remove the set screw, noting the following:
After being installed, the set screw is crimped at two
places with a punch.
Remove the crimped portions with a drill
A
, then loosen
the set screw. Remove the steel ball
B
located below
the end of the set screw.
Remove the piston nut.
Note:
The piston nut was torque tightened on assembly. A
torque 1.5 times the tightening torque is necessary to loosen
the piston nut. Prepare a power wrench using a hydraulic
cylinder (see
Ram Piston Head Nut - Removal and Fitting
).
