We will now plan to replace the wire rope or other wearable parts of the
Retractable, in case they have been damaged or worn out. Open the 3 Nos
Grub Screw with the help of 2.0mm allen key as shown in figure above.
If Grub screw will found stuck or very tight then follow the below steps
of actions to open them:
1. First we will use L-Type Allen key to loosen the grub screw and T-type
Allen key for further opening.
2. While loosening the screws if any screw is not able to loose (stuck into the
hole) then we will not try to apply excessive force on allen, as it will lead
to deform the drive of grub screw.
3. Fix the assembly in Three jaw chuck and with the help of chuck nut
opening gauge try to move the chuck nut anticlockwise for a bit distance
(stop when cuck nut start moving).
4. Now again use L-Type Allen Key and try to loosen the screw, it will get
loose with a ‘click’ sound. Stop and open the grub screw with T-type
Allen key.
Hold the assembly in the Drum Holding Fixture as shown.
Open the Chuck Nut by using the Torque Wrench & the Excel Socket as
shown in above figure.
