Fitting a thumb turn cylinder, or replacing just the thumb turn, is a straightforward process. Here’s a step-by-step guide based on the provided reference:
Replacing or Fitting a Thumb Turn:
Here's how to install a thumb turn, which is often part of a cylinder lock mechanism.
- Locate the cylinder shaft: This is the part of the cylinder that the thumb turn attaches to.
- Position the thumb turn: Place the thumb turn directly over the cylinder shaft.
- Secure with set screw: Tighten the set screw on the thumb turn using an Allen wrench. This set screw is what holds the thumb turn firmly in place.
Important Notes:
- Replacing Only the Thumb Turn: According to the reference, if you are only replacing the thumb turn and not the entire cylinder, you do not need to remove the cylinder. The process involves positioning the new thumb turn on the existing cylinder shaft and tightening it with the set screw.
Tools Required
- Allen Wrench: This is essential to tighten the set screw securing the thumb turn. The reference specifically mentions its use.
