Disassembling Ogura Electric Clutches: A Step-By-Step Guide

how to disassemble an ogura electric clutch

Disassembling an Ogura electric clutch can be a tricky process. One method that has proven successful involves using a press to separate the components, as some clutches may require over 25 tons of force to disassemble. It is important to note that this process can be delicate, as one wrong move could result in damaged threads. When disassembling, it is recommended to put the bolt back in partially to ensure that the gear puller threaded shaft presses against the bolt head. This prevents damage to the threads.

Use a two-jaw gear puller

When disassembling an Ogura electric clutch, one of the steps involves using a two-jaw gear puller. This is a tool that helps to remove the clutch by applying light pressure and then sliding the clutch off.

Firstly, ensure that you have partially replaced the bolt. This is important because it ensures that the gear puller's threaded shaft presses against the bolt head, preventing any damage to the threads.

Position the two-jaw gear puller so that it is securely in place and ready to apply light pressure. Make sure the tool is stable and correctly aligned with the clutch.

Now, carefully apply light pressure using the gear puller. This will initiate the separation of the clutch components. The specific pressure required may vary depending on the condition and tightness of the clutch, so proceed with caution and adjust as necessary.

As you continue to apply light and controlled pressure, the two-jaw gear puller will do its job, and the clutch will start to slide off. Maintain the pressure until the clutch is completely removed. Once it is off, you can proceed with further disassembly steps or inspect the clutch for any required maintenance or repairs.

Using a two-jaw gear puller is a standard approach when disassembling an Ogura electric clutch, and with careful execution, it can effectively separate the clutch components without causing damage.

Put the bolt back in partially to avoid damage

When disassembling an Ogura electric clutch, it is important to take care when using a gear puller to remove the clutch. To avoid damaging the threads, ensure that you put the bolt back in partially. This will allow the gear puller threaded shaft to press against the bolt head, rather than damaging the threads. This is a crucial step to prevent damage to the clutch during the disassembly process.

When using the gear puller, apply light pressure and use a two-jaw puller. This method has proven effective and will allow the clutch to slide off easily. By putting the bolt back in partially, you create a surface for the gear puller to press against, reducing the risk of damage to the threads.

It is important to note that this advice is specifically for the disassembly of an Ogura electric clutch and may not apply to other types of clutches. Each clutch may have unique design features and disassembly requirements, so it is important to consult relevant resources or experts for specific instructions.

When partially reinserting the bolt, ensure that it is secure and properly aligned. This will ensure that the gear puller exerts force on the bolt head rather than the threads. This step demonstrates the importance of understanding the mechanics of the clutch and the tools used for disassembly.

By following this advice and taking a cautious approach, you can help ensure a successful and damage-free disassembly of the Ogura electric clutch. This process may require some trial and error, and it is always beneficial to consult experienced sources or individuals with hands-on knowledge of the process.

Remove the backplate and studs

To remove the backplate and studs of an Ogura electric clutch, you will need to use a gear puller. Firstly, ensure that there is no power to the clutch and that the IGN is turned off. Then, follow these steps:

  • Use light pressure with a two-jaw gear puller to remove the clutch. This method has proven successful in the past, with the clutch sliding off easily.
  • Ensure that you partially put the bolt back in so that the gear puller's threaded shaft presses against the bolt head. This will prevent any damage to the threads.
  • Once the clutch is removed, you will have access to the backplate and studs.
  • The backplate is held in place by three studs with springs and nylon insert nuts. Remove these nuts and springs to detach the backplate.
  • Carefully lift or slide off the backplate, exposing the internal components of the clutch.

By following these steps, you will be able to successfully remove the backplate and studs of the Ogura electric clutch, allowing you to access and inspect the internal components for further repairs or maintenance.

Use a press to separate the components

To disassemble an Ogura electric clutch, one of the methods you can use is a press. This method has been used by others to successfully disassemble the clutch.

Firstly, ensure you have the right equipment. In this case, a press with over 25 tons of force is required. This is a substantial amount of force, so ensure your press can handle this capacity.

Next, you will need to carefully apply this force to the clutch. It is important to do this evenly and gradually to avoid damaging the components. Even with the right equipment, there is a risk of warping or damaging the clutch faces, so proceed with caution.

Once the clutch is separated, you can inspect the individual components. It is likely that you will need to resurface the clutch faces, as they may be warped from the pressure. This can be done with a lathe, for example.

You may also need to clean and inspect the bearings, as these can become dirty and frozen, causing issues. A full inspection of all components is recommended to identify any issues and ensure they are in good condition for reassembly.

Finally, with the components separated, you can choose to reassemble the clutch or replace individual parts as required.

Reface the clutch faces

Refacing the clutch faces is an important step in the process of disassembling and reassembling an Ogura electric clutch. This process can help to restore the clutch's functionality and improve its performance. Here's a step-by-step guide to refacing the clutch faces:

Firstly, it's important to understand the cause of the clutch issues. In many cases, Ogura electric clutches fail due to warped clutch faces, which reduce the friction area available to hold the load. This can lead to slippage and reduced performance. By refacing the clutch faces, you can restore the necessary friction surface and improve the clutch's gripping power.

Before beginning the refacing process, ensure that you have the necessary tools and equipment. A lathe machine is commonly used to resurface clutch faces and create a smooth, even surface. If you don't have access to a lathe, you may be able to use other precision machining tools, such as a mill or a surface grinder, depending on your resources and expertise.

Once you have the required tools, disassemble the clutch assembly carefully. This step requires some mechanical knowledge and skill to ensure that the relevant components are removed without causing damage. Remove the clutch faces and inspect them thoroughly for any signs of wear, warping, or damage. Clean the clutch faces to remove any debris, grease, or contaminants that could affect the refacing process.

Set up the lathe or your chosen machining tool and securely mount the clutch faces onto the machine. Ensure that the clutch faces are held firmly and are properly aligned with the machining tool. Start the machine and apply a consistent, controlled cut to the clutch faces. This process will remove a thin layer of material from the surface, creating a smooth and even finish. Take care to maintain the appropriate speed and feed rate to achieve the desired surface finish and accuracy.

Finally, once the refacing process is complete, inspect the clutch faces again. Ensure that they meet the required specifications and are free from any imperfections or irregularities. It's crucial to achieve the correct surface finish and flatness to ensure effective clutch performance. Reassemble the clutch, following the appropriate procedures and torque specifications, and test the clutch to ensure it functions correctly.

By carefully refacing the clutch faces, you can significantly improve the performance and lifespan of your Ogura electric clutch, saving you from having to purchase a new one. This process allows you to restore the necessary friction surface and ensure optimal clutch engagement and disengagement, enhancing the overall performance of your machinery.
