General
The following repair instructions are intended to assist in inspections and repairs to
be carried out, the instructions are valid for two pumps. When ordering in going parts
to your pump, please use the catalogue that was delivered with the roller. Also inform
us of the machines S/N and the P/N and S/N for the pump. That will allow us to use
our special knowledge and guarantee that the correct parts are delivered. Prerequisite
is that this work is carried out only by qualified personnel.
These units are manufactured with great care and with adherence to defined
tolerances to the highest manufacturing accuracy, and therefore the following points
must be given particular attention:
Dismantling
1. When dismantling the unit from the machine, immediately close openings
with plugs to prevent ingress of dirt.
2. Make note of the details on code plate, such as serial number, type number
and running time of unit (for ordering spare parts).
3. Remove external dirt (cleaning spirit or trichlor solution).
4. Have a clean work place ready, lay out tools ready.
5. Use only non-threading cleaning rags.
6. Before dismantling components, mark parts to ensure correct re-assembly.
7. Carry out step by step dismantling.
8. The appearance of the parts removed often gives an indication of the condi-
tion of the system. For example:
Scored sliding surfaces, - contaminated operating fluid
heavy abrasion
Discoloration of components - overheating of operating fluid,
with heavy loading incorrect choice of viscosity
or inadequate specifications
of operating fluid
- insufficient oil
