How to Install a Clock Kit with Bell Strike in a Wall Clock Case

Installing a mechanical clock kit with a bell strike can feel intimidating, especially if you’re new to clock building or retrofitting. But with the right steps and a bit of patience, anyone can install a quality clock movement and enjoy the satisfying chime of a traditional bell strike. Whether you're crafting a wall clock from scratch or restoring an antique case, this guide will walk you through everything you need to know.

What Comes in a Clock Kit with Bell Strike?

When you order a mechanical clock kit with a bell strike from Clockworks.com, you receive all the core components needed to build a functioning timepiece. The kit includes:

• A mechanical movement designed for wall clocks
• Matching hands (hour, minute, and second if applicable)
• Winding key or crank
• Mounting hardware

Some kits may also come with pendulum parts or decorative elements depending on the model.

What Tools Do You Need Before You Start?

Before you begin installation, gather the following tools to make the process smoother:

• Small flat-head and Phillips screwdriver
• Needle-nose pliers
• A level

Having a clean, stable workspace also helps reduce errors and protect delicate components.

Step-by-Step Guide to Installing the Clock Kit

1. Prep the Clock Case

Open your clock case and clear out any debris or old mounting hardware. You need a flat, vertical surface to mount the movement. Check that your case can accommodate the depth of the bell strike mechanism and that the pendulum (if included) will swing freely.

If you're retrofitting an old case, measure the distance from the dial center to the back of the case. Compare this with the depth of your movement to ensure a proper fit.

2. Mount the Dial (Face) and Hands

Attach the dial to the front of the movement using the provided mounting posts. Line up the dial so the center hole matches the shaft of the movement. Secure it with the appropriate screws or fasteners.

Next, install the hour hand by gently pressing it onto the shaft. Follow with the minute hand, which often has a nut or pin to hold it in place. If your kit includes a second hand, install it last by pressing it into the central pin.

Pro tip: Align all hands to the 12 o'clock position before tightening to make initial calibration easier.

3. Secure the Movement Inside the Case

Slide the movement into position from the back of the clock case. Ensure the winding arbors and hand shaft line up with the dial openings. Use the included brackets or screws to mount the movement securely to the case.

Important: Keep the movement level. Uneven installation can cause mechanical issues or strike malfunctions.

4. Attach the Bell and Bell Hammer

Locate the bell post hole—usually near the top or rear of the movement. Install the post and attach the bell securely. Then, align the bell hammer so it strikes the bell with a firm but not excessive force. Adjust the angle if needed for a crisp, clear tone.

Watch for clearance issues: the hammer should not rest on the bell when idle, or it may dull the sound.

5. Hang the Pendulum (if applicable)

Some bell strike kits include a pendulum. Attach the pendulum leader to the suspension spring and then hook the pendulum onto the leader.

Once installed, gently push the pendulum to one side and release. It should swing freely for several minutes. If not, check for obstructions or make sure the clock is level.

6. Wind and Set the Clock

Use the provided key or crank to wind the mainspring(s). Depending on your model, you may have one, two, or three winding points. Turn slowly and stop when you feel resistance.

Now, set the time by turning the minute hand clockwise. If the bell strikes as you pass an hour or half-hour mark, pause and let it finish before continuing.

7. Test the Bell Strike Function

Listen for the bell strike at the top and bottom of the hour. If the bell doesn’t sound or sounds weak:

• Check the hammer alignment
• Verify the bell is securely attached
• Make sure the movement is fully wound
• Ensure nothing obstructs the strike mechanism

You can manually test the strike by gently moving the strike lever, but do so cautiously to avoid damaging the mechanism.

What Are Common Installation Mistakes?

• Forgetting to level the clock – Leads to poor timekeeping or strike issues
• Over-tightening hand nuts – Can prevent smooth hand movement
• Improper bell hammer positioning – Results in dull or inconsistent chimes
• Skipping case measurements – Causes movement to sit too deep or shallow

Taking a few extra minutes at each step prevents future headaches.

Final Tips for a Perfect Install

• Always refer to the specific movement instructions included in your kit
• Never force any part into place
• Take photos during each step if you plan to install similar kits again
• Let the clock run for 24 hours before making adjustments

Installing a mechanical wall clock kit with bell strike is a rewarding DIY project that results in a beautiful, functional piece. The chime adds warmth and character to any room, and with proper installation, your new clock will run reliably for decades.
