POSSIBLE FAILURE / CAUSE & SOLUTION
Cylinder Leaks Around Rod:
CAUSE:
Faulty Seals On Cylinder Gland?
SOLUTION:
Dis-Assemble and Re-Seal Gland. Seals can be damaged by foreign objects, or
worn by abrasive material such as Dirt getting into Seal and/or Rod. Seals can also
be damaged during Assembly and this type of damage will almost always show up
shortly after being put in service.
CAUSE:
Damage To Cylinder Rod?
SOLUTION:
Determine the cause of the Damage, Dent, Scratch, Rust and/or something stuck
to Rod. The Damage and cause should always be identified and corrected before
any repairs are made, Repairing the failure and leaving the cause will result in more
failure. In Some cases a Cylinder Rod can be cleaned up with CROCUS CLOTH
(a very fine abrasive material), DO NOT USE anything more abrasive than crocus
cloth. A major problem for cylinders is storage when unit is not being used for a while,
The Rods are a chrome alloy but if subjected to moisture long enough they will rust,
This is not a problem when being operated as they are be cleaned with every in and
out stroke. If Unit is going to be stored for an extended time you can coat Rods
(Exposed Part) with Oil or Grease to protect them, But If you do this it must be
cleaned off before running to remove the Dust that will have collected on rod from
Oil and grease.
CAUSE:
Cylinder Rod Bent?
SOLUTION:
Determine and correct cause of bent Rod, Replace Rod and Re-Seal Cylinder.
Cylinder Moves On Its Own:
CAUSE:
Control Valve Spool Stuck?
SOLUTION:
Locate stuck Spool, repair or replace Spool, Determine why Spool is stuck, Debris,
Foreign Objects, Contamination, Broken Spool Components and etc. If just the
Spool is replaced and the reason it failed is not corrected, it will fail again.
CAUSE:
Return Spring Broken in Control Valve?
SOLUTION:
Repair or Replace Spring, Determine why it broke.
CAUSE:
Binding of Control Cables or Linkage? (Remote Cable Control Models)
SOLUTION:
Determine cause of Cable Binding or Sticking, repair or replace as required.
Sometimes it may be the Linkage sticking or binding and not the Cable, It may be
required to disconnect Cables from Linkage to determine which is sticking, If it is
the Linkage repair as needed. Cables may stick because of internal abrasion inside
calve Housing, Some times this damage is not visible.
