Removal and Disassembly of the Head Drive Assembly

Prerequisites:
Drawing of the Radial Insertion Head Assembly
Electrical Wires Disconnected
Insertion Head Tooling has been removed
Comments:
This procedure assumes that the head drive assembly is being disassembled
to replace the drive mechanism.
To rebuild this assembly, reference the reassembly procedure found in this
module.
If possible, it is more efficient to remove the motors and bearings from the
assembly with the casting secured to the machine.
Procedure:


1.Power down the machine and perform Lockout/Tagout according to
local procedures.

 

 

2.Use a clamp to secure the head drive assembly, and remove the 4
mounting bolts. Lift the head drive assembly from the machine.

 

          

 

3.To replace the drive mechanism, first loosen the socket head cap screw
and remove the threaded locking collar clamp from the top of the drive
mechanism shaft. This allows the separation of the bearing assembly
from the top of the drive mechanism.

 

 

4.Loosen the screw in the push rod clamp and unscrew the push rod. This
allows the bearing assembly to completely separate from the drive
mechanism.
