5.5.2 Ram Removal (not required to redress ram seals)
•
Remove Ram from Actuator, by sliding the Ram off the Ram Tee.
5.5.3 Ram Seal Redress
•
The Inner Ram Seals can be removed by simply sliding the seal out to
either side
•
The Outer Seal can be removed by levering out one end with a suitable
instrument and simply pulling off.
•
The Ram is now completely stripped down. Clean and inspect all parts for
evidence of damage or excessive wear. Check the seals and replace if
required. Repair or replace any damaged or worn parts. If the seals are to
be redressed use the parts from the specified redress kit.
•
Assemble Outer Seals by pushing the tab into the slot in the ram and
working it around the radius of the ram. Tap home using a rubber or hide
mallet and if required use a screwdriver to lever the second tab over the
edge of the slot. Take care not to significantly damage Seal during
assembly but expect that some slithers of rubber will be produced as the
corners of the rubber seals are removed by the assembly operation. Tap
all around the circumference of the seal to ensure that it is bedded into the
groove and that the seal is not protruding above the ram diameter.
•
Slide the Inner Seals into Ram taking care not to dislodge the outerseal in
the process.
