COMPONENT REPLACEMENT
The Group 22 was designed modularly for
ease of maintenance and parts replacement.
The individual components of the actuator are
available in replacement parts kits as detailed in the
replacement parts kits tables in this section. Each
replacement parts kit includes the component(s),
necessary hardware, and detailed instructions for
installation of the parts.
HOW TO ORDER SPARE PARTS
Any customer replacement kit may be purchased
for spare parts, however several kits have been
selected by the factory as recommended spares.
Contact your Beck Sales Engineer for questions
regarding recommended replacement parts
particular to your application. Parts may be ordered
by mail, telephone, fax or e-mail, with the confirming
order sent to the factory.
ROUTINE MAINTENANCE
Beck actuators require only a minimum of
routine maintenance. At regular plant maintenance
intervals, a visual inspection is recommended to
verify that the connection to the final control element
is intact and operating normally. If vibration is
present, check the electrical terminal connections
and other hardware for tightness. Check the conduit
seals for any moisture penetration and reseal if
necessary.
LUBRICATION
The Group 22 actuator has a grease filled gear
housing, so periodic lubrication is not required.
However, to extend the life of the linkage, rod ends
should be lubricated periodically.
GASKETS
During routine service, inspect removed cover
gaskets for wear or damage. In order to protect
internal components, worn or damaged gaskets
and O-rings should be replaced.
To remove, scrape all of the old adhesive and
gasket material from the body housing and cover.
The DCM cover, Terminal Block cover and Position
Sensing (Control End) cover have self-adhering,
silicone rubber gaskets. Peel the backing off the
replacement gasket and carefully apply to the
actuator body. Other gaskets are a cork-rubber
composite. Cement the new gasket to the actuator
body using a gasket cement such as 3M #847
Rubber and Gasket Adhesive, or equivalent.
MOTOR
The motor assembly is not field-repairable and
is intended to last for the lifetime of the actuator.
Disassembly of the motor will result in a loss of
torque that can only be restored by returning the
motor to the factory for re-magnetizing.
If you suspect a motor problem, contact the
factory for assistance.
CAUTION
To prevent sudden movement,
block the actuator crank arm before
removing the motor
—
failure to do
so could cause serious injury or
damage to equipment.
