Fig. 7 Backup O-ring orientation
Before you remove the O-rings from the RBRsolo/duet, make your self familiar with their
orientation and location. Inspect the new O-rings provided in the loggers support kit – there
are two types. The back-up O-ring is a flat O-ring with a concave channel on one side. The
main O-ring is round.
Inspecting O-rings
Give particular attention to the following areas:
•
The surface of the O-ring itself
•
The mating surface on the inside of the case between the threads and the open end
•
The inner surfaces of the groove in the end cap where the O-ring sits
Any dirt present should be removed by wiping thoroughly with a soft, lint-free cloth. When
cleaning, never use any material or tool which could scratch the O-ring or any of its mating
surfaces. If any dirt is present in the O-ring groove, then the O-ring should be removed as
described below to allow thorough cleaning of the groove. If an O-ring needs to be removed
for any reason, it should be replaced.
If the O-ring is scratched, cut, distorted, perished or defective in any other way it must be
replaced. If any of the surfaces of the O-ring groove are scratched, pitted or otherwise damaged,
the logger may need to be returned to RBR for refurbishment: please contact us for advice
support@rbr-global.com.
Replacing an O-ring
1. Lever the O-ring from its groove. Use a soft plastic or wood tool; do not use a metal
screwdriver or any other tool which may scratch the surfaces of the O-ring groove: doing
so will probably render the end cap useless. Slide the O-ring out of its groove and off the
logger. The O-ring may need to stretch quite a bit as it is pushed off; this requires some
effort but can be done by hand.
