Brunswick Phonograph: Motor Removal Guide

If you want to remove the motor from your Brunswick phonograph, you'll need to start by removing the turntable and the crank. You'll then need to take out the corner screws of the motor board, which will allow you to lift the motor out of the phonograph. It's important to note that the motor will still be attached to the board when you do this. If you're unsure about any of these steps, it's recommended that you seek professional help to avoid causing any damage to your phonograph.

Removing the turntable and crank

To remove the turntable and crank from your Brunswick phonograph, you will need to first lift up on the edges of the turntable and then pull it towards you. It should pop right off. Next, turn the crank backwards, or counterclockwise, until it comes off. You can then proceed to remove the motor by taking out the corner screws of the motor board and lifting it out of the phonograph.

It is important to have the right tools for this task. Make sure you have some good screwdrivers—big gunsmithing screwdrivers can be found at a gun store. It is also recommended to drip a little sewing machine oil on the screw heads and let it sit for a moment to help remove the screws more easily.

If you are not interested in getting into phonograph rebuilding as a hobby, you may want to consider sending the motor to a professional repair service or to a specialist in your area.

Unscrewing the motor board

First, you will need to remove the turntable by gently lifting it up from the edges and pulling it towards you. This will expose the underlying components, including the motor board. It is important to be cautious during this step to avoid damaging any of the delicate parts.

Once the turntable is removed, locate the crank. The crank is the part that you would typically turn to operate the phonograph. To remove it, turn it backwards or counterclockwise until it comes off. This will help you access the motor board more easily.

Now, you will need to locate the screws that hold the motor board in place. These screws are typically located around the edge of the black metal bedplate, which is the platform that the turntable sits on. Before attempting to remove these screws, it is recommended to apply a small amount of sewing machine oil, such as Zoom Spout, to the screw heads. This will help loosen the screws and make them easier to remove.

Using a suitable screwdriver, such as a gunsmithing screwdriver, carefully unscrew each of the screws on the edge of the bedplate. Place them in a safe location so that you don't lose them.

With the screws removed, you can now carefully lift the motor board out of the phonograph. Be cautious during this step as the motor board is likely still attached to the motor itself. You don't want to accidentally drop or damage the motor.

If you are planning to send the motor for servicing, it is important to keep the motor attached to the board. Many repair services, such as the one mentioned in one source, specifically request that the motor be sent to them while still mounted on the board. This allows them to correctly test for speed variations and other common motor issues.

By following these steps, you should be able to successfully unscrew and remove the motor board from your Brunswick phonograph. Remember to take your time, be gentle with the components, and always refer to a reliable guide or manual if you are unsure about any steps.

Cleaning the motor

The first step in cleaning the motor of your Brunswick phonograph is to remove it from the device. To do this, pull off the turntable and remove the crank. Then, take out the corner screws of the motor board and lift it out of the phonograph. The motor will still be attached to the board.

Once the motor is removed, it can be cleaned. This involves dismantling the motor and cleaning the individual components. This includes the frame, gears, and all associated parts. The old grease and dirt should be scrubbed out, and the motor should be tested for operation and set to the proper speed after cleaning and reassembly.

It is important to note that some parts of the phonograph, such as the mainsprings, may need to be replaced if they are broken or damaged. The governor, which controls the speed of the phonograph, may also need new springs if the device plays too fast or unevenly.

In addition to cleaning the motor, it is recommended to clean and polish the metal parts on the board, such as the brake and speed control. This will help ensure that your Brunswick phonograph functions optimally.

If you are unsure about any part of the process, it is best to consult a professional or seek advice from online forums dedicated to antique phonograph restoration.

Identifying the model

Examine the Physical Characteristics

Start by carefully inspecting the physical characteristics of your phonograph. Look for any model numbers, markings, or labels that may be present on the device. These can often be found on metal identification tags attached to the frame or cabinet, or on transfer labels affixed to the lid or front of the cabinet. Additionally, examine the overall design and construction of the phonograph, including its size, shape, and any distinctive features.

Consult Reference Materials

Use reference materials such as manufacturer's catalogs, identification guides, and online resources to help you identify the model. Brunswick phonographs were produced with various cabinet designs, including console (upright), tabletop, and portable models. By comparing the physical characteristics of your phonograph with those in reference materials, you can narrow down the possible models.

Seek Expert Advice

If you're having difficulty identifying the model on your own, consider seeking assistance from experts or fellow collectors. There are online forums and communities dedicated to antique phonographs, where members share their knowledge and expertise. You can post detailed descriptions and photographs of your phonograph to solicit information from other collectors who may be familiar with the model.

Example Models

• Model 110: This model was available in both oak and mahogany, and originally sold for $150 in 1921.
• Model 101: A crank-type portable phonograph.
• Model 105: A tabletop model known for its great performance.
• Model YO: A console record phonograph model from the 1920s.
• Model 217: A phonograph with a motor and screws.

Remember that proper identification of the model is crucial for repair, restoration, or valuation purposes. Take your time to examine the device thoroughly and utilise the available resources to increase the chances of accurate identification.

Repairing the phonograph

If you're looking to repair a Brunswick phonograph, there are a few things to keep in mind. Firstly, these machines are quite old, so it's important to handle them with care and be prepared for some wear and tear.

When it comes to removing the motor, the process is relatively straightforward. Start by pulling off the turntable and removing the crank. Then, take out the corner screws of the motor board and lift it out of the phonograph. The motor will still be attached to the board. It's important to note that you should send the motor to a repair service with the board still attached, as this allows for proper testing.

One common issue with phonographs is the build-up of dirt and hardened grease over time, which can affect the performance of the motor. To fix this, you can send the motor to a repair service for a full strip-down and cleaning, or attempt to clean it yourself with a solvent. It's important to be careful when handling the motor, as some parts can be dangerous to remove, such as the governor, which controls the speed of the phonograph.

Another issue that may arise is broken mainsprings. These can be replaced, but it's important to make sure that the new springs are installed correctly and packed with grease. Additionally, the governor may need new springs, and the weights on it may need to be replaced if they are thrown off.

After around 80-100 years, the reproducer (sound box) of your phonograph will likely need to be rebuilt. This involves replacing parts such as gaskets, springs, the diaphragm, and the needle bar.

If you're unsure about any part of the repair process, it's always best to consult a professional or seek advice from a forum dedicated to phonograph repair and restoration.
