As a commonly used precision measuring tool, dial indicators may encounter situations where the pointer is damaged
or needs to be replaced during use. This article will detail the disassembly steps of the dial indicator pointer and provide
solutions to some common problems, helping you to safely and correctly disassemble and maintain the dial indicator.
I. Preparation Work
1. Before disassembling the dial indicator pointer, we need to prepare some necessary tools, such as: tweezers,
a small screwdriver, a clean soft cloth, and a safe workbench.
2. Ensure the workbench is clean and dust-free to prevent dust from entering the dial indicator and affecting
its accuracy. At the same time, prepare appropriate lighting tools to observe the structure of the pointer and
the disassembly process more clearly.
3. Good preparation is the key to successfully disassembling the pointer.
II. Disassembly Steps
1. First, use a clean soft cloth to gently wipe the surface of the micrometer to remove dust and stains.
2. Then, carefully unscrew the fixing screws of the dial using a small screwdriver. Some dial indicators may
not have screws for fixation; instead, they are fixed by clasps or other methods. Depending on the specific situation,
the appropriate operation should be carried out. Be careful not to apply excessive force to avoid damaging
the dial or other components.
3. After unscrewing the screws, gently remove the dial. Then you can see the pointer. Use tweezers to hold the base
of the pointer and gently pull it out. Be careful not to touch the surface of the pointer to avoid leaving fingerprints
or scratches.
4. The pointers of some dial indicators may be rather tight and require a bit of force to pull out. If this happens,
you can try using a pair of forceps to gently rotate the pointer until it becomes loose, then pull it out.
Do not use brute force as it may cause damage to the pointer or other components.
III. Common Problems and Solutions
1. Unable to remove the pointer: If the pointer is too tightly attached and cannot be removed, you can try using
tweezers to gently rotate the pointer, or use some professional disassembly tools. If still unable to remove it,
it is recommended to contact a professional repair person for handling.
2. Pointer deformation: If the pointer gets deformed during disassembly, a new pointer needs to be replaced.
It is recommended to purchase original factory parts to ensure the accuracy and performance of the micrometer.
3. Dial damage: If the dial is accidentally damaged during the disassembly process, a new dial needs to be replaced.
It is also recommended to purchase original factory parts.
IV. Installing the New Pointer
1. When installing the new pointer, align the root of the pointer with the pointer axis, and then gently insert it.
Ensure that the pointer is securely installed and can rotate freely.
2. After installing the pointer, reinstall the dial and tighten the fixing screws. Pay attention to maintaining an
appropriate degree of screw tightness. If it is too loose, the dial may become loose; if it is too tight, it may
damage the dial.
3. After the installation is completed, it is necessary to check whether the pointer can rotate normally
and whether the accuracy of the dial indicator has been affected.
V. Notes
1. When disassembling the pointer of the micrometer, be extremely careful to avoid damaging the pointer.
2. If you are unsure about how to operate, it is recommended to contact a professional maintenance
technician for assistance.
3. Do not disassemble any other internal components of the indicator at will, as this may affect its
accuracy and performance.
Here are the questions you might be interested in and their answers:
Q: What is the material of the pointer of the dial indicator?
A: The pointer of a dial indicator is usually made of aluminum alloy or other lightweight metals.
Q: How do you clean a dial indicator?
A: You can use a clean soft cloth to wipe the surface of the micrometer to remove dust and stains. Do not use any
chemical cleaners as they may damage the micrometer.
Q: What is the price of the pointer for the dial indicator?
A: The price of the dial of the indicator depends on the brand and model. The exact price needs to be inquired
from the relevant suppliers.
The disassembly of the pointer of a dial indicator requires certain skills and experience. We hope that the disassembly
steps provided and the solutions to common problems can help you better maintain the dial indicator and extend its
service life.
