MAINTENANCE 

 

This section covers replacement of many 

components of the Group 14 drive.  Note that 
some components are not field repairable.
 

If it should ever be necessary to replace the 

output gear, shaft, or output shaft bearings, a  
major overhaul is required and the drive should 
be returned to the factory.

 

During routine service, inspect the gaskets 

and O-rings for wear or damage.  In order to 
protect internal components, worn or damaged 
gaskets and O-rings should be replaced.
 

To remove the main gear cover, terminal 

compartment, or the motor gaskets, scrape all 
of the old adhesive and gasket material from the 
body housing and cover.  Cement the new gasket 
to the drive body using a gasket cement such 
as 3M #847 Rubber and Gasket Adhesive, or 
equivalent.
 

O-ring seals are used between the body 

and the top and bottom bearing plates.  Before 
installing a new O-ring, lubricate it with light 
machine oil.
 

The large top cover is sealed with rubber foam 

gasket material, 5/16” in diameter.  To replace 
this material, scrape the old gasket material and 
cement from the groove.  Cement the new foam 
gasket into the groove with 3M #847 Rubber and 
Gasket Adhesive, or equivalent.  Cut the ends 
of the material on an angle and cement them 
together with this same adhesive.

 

Worn or damaged output shaft and motor 

shaft seals should be replaced to prevent damage 
to internal bearings and drive train parts.
 

To remove the shaft seal, push the blade of a 

small screwdriver along the shaft and under the 
seal lip.  CAUTION:  The seal is approximately 
1/4” wide.  Do not force the screwdriver blade 
beyond the width of the seal; damage to the shaft 
bearing could result.  Pry up on the seal and 
force it out of the housing.  Clean the shaft and 
housing and press in the replacement seal with 
the closed side facing outward.

 

There are some field replaceable bearings 

in the Group 14 drive.  Consult the factory for 
details.

 

The control motor is not field-repairable.  

Disassembly of the motor will result in a loss of 
torque that can only be restored by returning the 
motor to the factory for remagnetizing.

 

To remove the motor, first disconnect the motor 

wires in the terminal compartment of the control 
drive.  The wiring is under the terminal board.  
Remove the black wire from the terminal post, cut 
the green motor wire near the green-yellow-red 
butt joint and disconnect the red wire from the re-
green-blue butt connection.  Remove the hardware 
that secures the motor (model 14-10_ has three 
10-32 socket head cap screws and model 14-20_ 
has four 1/4-20 hex head bolts).  Carefully slide 
the motor out of the drive body.
 

To install the motor, insert the three-wire 

sleeve through the wire hole in the motor mount 
and into the terminal compartment.  Carefully slide 
the motor into the drive body, rotate the motor 
shaft if necessary to engage the pinion with the 
first combination gear.  Install motor mounting 
hardware and torque to appropriate values (10-32 
socket head cap screws (20 lb-in) or 1/4-20 hex 
bolts (6 lb-ft)).  Reconnect the motor wires.

 

The motor resistor assembly and capacitor 

are located in the top compartment beside the 
Calibar.  To replace a resistor or capacitor, remove 
the top cover (15/16” bolt head).  Remove the 
existing part and transfer the wires one at a time 
to the replacement part.  Inspect the top cover 
gasket and replace if necessary.  Replace the top 
cover.  Tighten the top cover bolt just enough to 
compress the O-ring seal.
