Silicone Sampling Method - Kohler SFGLD480 Operation & Maintenance Manual

3. SILICONE SAMPLING METHOD

An analysis of the damper silicone is essential to determine whether its properties are optimum or not.
The filling plugs will be found, diametrically opposed, on the damper cover. If there is a reasonably easy access
to one of those plugs, sampling can be done with the damper installed on the engine. Otherwise, put the
damper in a normal vertical position during the sampling process. As for engines with double damper, both
dampers must be checked.
NOTE
For HGM series it is not necessary to take a periodical silicone sample for analysis. The damper must only be
changed when the schedule program sets it.
It is recommended to place the damper so that both filling plugs are roughly in a horizontal position and to leave it
in that position for at least one hour before starting to take samples. Depending on the damper model, any of
various thread sizes are used for the filling holes and, consequently, the threads vary at either end of the sample
container.
The silicone fluid sampling procedure is described below:

DAMPER CONDITION MONITORING
Assuming you know the thread size of the damper plug hole,
prepare a sample container and remove its screw-on cap from
the end to be introduced into the damper
Remove the filling plug from the damper cover, while holding the
container ready to be inserted immediately
Screw the container totally into the hole of the filling plug
Remove the second screw-on cap from the container
