How to Remove and Replace a Drill Press Spindle

The spindle is a crucial part of your drill press that undergoes a lot of stress during drilling. Over time, the spindle may bend or the bearings that hold it in place may fail. Instead of taking it to a repair shop and spending a fortune, you can replace the spindle yourself. In this article, we will guide you through the process step by step, saving you both time and money.

Removing the Quill Assembly

1. Remove the drill chuck

Use the appropriate drill chuck removal tool to remove the chuck from your drill press. This tool will vary depending on your drill press model. Removing the chuck is an essential first step in accessing the spindle.

2. Remove the belt

Open the drill’s top cover and remove the drive belt. This will allow you to proceed with the disassembly of the quill assembly.

3. Remove the quill set screw

First, remove the nut threaded onto the set screw. Then, unscrew the set screw from the drill press body. This will free the quill assembly for further disassembly.

4. Remove the return spring assembly

Caution: The return spring assembly is under tension. Exercise caution to avoid injury.

5. Remove the handle and quill

The handle and quill are held together by gears. Remove the handle to free the quill assembly.

Removing and Replacing the Spindle

1. Remove the quill retaining ring

Use retaining ring pliers to remove the retaining ring from the quill assembly. This will allow you to separate the quill from the spindle.

2. Separate the quill and spindle

Secure the quill assembly in a vice and tap the spindle out of the quill. This will separate the two parts for further examination.

3. Remove the spindle bearing

Set the spindle in a vice and tap the bearing off the spindle. This will allow you to replace the bearing with a new one.

4. Install the bearing on your new spindle

Set the new spindle in a vice and tap the bearing onto the spindle. Make sure it is secure before proceeding.

5. Install the spindle into the quill

Insert the spindle into the quill and secure it in place using a vice and gentle tapping. Take care not to damage the parts during this step.

6. Replace the retaining ring

Slide the retaining ring back into place on the quill assembly, ensuring that it sits securely in its groove.

Reinstalling the Quill Assembly

1. Remount the handle and quill

Slide the quill assembly back into position and insert the handle to secure it in place.

2. Install the return spring assembly

Exercise caution while reinstalling the return spring assembly, as it is under tension. Properly thread the nuts and adjust the tension to ensure smooth operation.

3. Adjust the handle tension

Fine-tune the tension of the return spring assembly by adjusting the nut until the handle moves smoothly. Aim for a slight amount of rubbing to ensure the tension is correct.
