Beck drives require only a minimum of routine 
maintenance.  A visual inspection is in order 
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.
LUBRICATION
 
Periodic lubrication is not required on Beck 
control drives.  However, it is recommended that 
during major shutdowns or outages, the drives 
in the most severe applications be inspected to 
determine the need to relubricate the drive gear 
train.
 
If your drive has a linkage, to extend the life of 
the linkage rod ends, they should be included in 
your scheduled lubrication program.
CAUTION
If your drive has a linkage, before removing 
the gear module assembly, block the control 
drive crank arm to prevent the crank arm and 
the gear train from moving when the change 
module is removed.
 
To inspect the gears, remove the gear module 
assembly on the 11-209/-269, -309/-369 and 
-409/-469.  On Model 11-159/-169, the motor 
must be removed to access the gears.  Clean the 
gears thoroughly, removing all old lubrication.
MAINTENANCE
 ROUTINE
11-409 Gear Module
 
Examine the gear teeth, shaft bore, and 
gear shafts for signs of excessive wear, scoring, 
or other damage.  If evidence of this damage 
is present, the drive should be returned to the 
factory for a detailed examination of the main 
gear, which requires complete disassembly of 
the drive.  See "HOW TO OBTAIN SERVICE" on 
page 87. 
 
If there is no evidence of damage to the 
gearing, recoat the teeth and shaft bores of all 
gears with a heavy layer of Fiske Lubriplate GR-
132 or equivalent (GR-132 is an E.P. grease with 
polymer additives).  The ball bearing on the output 
shaft and crown gear shaft have added double 
grease seals and require no maintenance for the 
life of the bearings.  Inspect all grease seals and 
replace any that show wear.  Reassemble the 
drive, referencing pages 8–14 for appropriate 
bolt torques.
