8100-104/C Long-Term Chamber Maintenance
The 8100-104/C Long-Term Chamber is designed to require only minimal
maintenance. The black neoprene collar gasket can be easily replaced should it
become damaged; two spare gaskets (p/n 6581-060) can be found in the Long-
Term Chamber Gasket Kit (p/n 8100-612). Instructions are also given for replacing
the tubing/cable assembly, replacing the thermistor assembly, and replacing the
shaft seal assembly.
Replacing the Collar Gasket
The Soil Collar Gasket should not need to be replaced unless it is cracked, brittle,
or otherwise worn. To replace the gasket, move the chamber to its open position.
Loosen the 24 screws on the chamber gasket plate. Remove the plate and gasket.
Align the new gasket with the screw holes and re-assemble. Torque screws to 4
lb.-in.
