Under no circumstances should any attempt be made to dismantle a
pressure relief valve which has not had the spring pressure relieved
(where applicable) or is mounted on a pump that is operating. Serious
personal injury or pump damage may occur.

Pump Dismantling and Assembly.
Before undertaking any work on the pump the Shutdown Procedure should be
followed in section 3.5, and site safety practices must be observed.
While dismantling or assembling the pump it is essential to ensure that the
pump and/or components are secured to provide adequate stability.
Large pump components or assemblies should be lifted using suitable
devices. Use threaded holes for attaching lifting eyes where appropriate.
During dismantling or before assembly all components should be inspected for
fit, wear, and damage. If worn or damaged the components should be
replaced before re-assembly.
The position of all parts should be identified as they are removed to ensure
they are reinstalled in the same position.
Lip-seals and O-rings are incorporated within the assembly. Regular
inspection and correct maintenance of these items will ensure that the
lubrication is sustained and the pump maximum working life is achieved. To
ensure this, it is extremely important that care is taken when removing and
installing new O-rings and lip-seals. When removing and replacing lip-seals
ensure that the location bore for the outside diameter and the seat for the back
of the lip-seal is not damaged as this may create a leakage path.
When removing Lip-seals or O-rings care should be taken to avoid
cutting or tearing the sealing faces as they pass over splines, threads or
other potentially sharp or abrasive edges
. All lip-seals and O-rings should
be carefully examined and if damaged in any way, replaced on assembly.
All O-rings and sealing lips of Lip-seals should be lightly lubricated with a
suitable lubricant (silicon grease, etc.) before installing.
Prior to assembly, ensure all parts are clean and free from burrs or damage.
When a vice is to be used, it should have protective jaws to avoid damage to
components. Do not apply undue force to install or position components.
All fasteners are required to be tightened to the required torque setting during
assembly, refer to section 5.2.
Bearing cones may be pressed into position providing the proper equipment
and procedures are employed to prevent component damage.
