How to repair a drill press spindle?
To repair the spindle on your Craftsman drill press model 14921331, we typically remove the quill assembly, inspect the spindle and bearings for wear, replace any damaged bearings or the spindle, then reassemble and verify smooth runout-free rotation before drilling again.
Safety first (before you touch the quill)
- Unplug the drill press; do not rely on the switch alone.
- Remove the bit and chuck key; lower the table for clearance.
- Wear eye protection; small retaining rings can spring loose.
- Support the quill so it cannot drop when the retainer is removed.
- Take photos as you go so the return spring and feed parts go back correctly.
Spindle repair steps (typical drill press design)
- Remove the chuck (often by lowering the quill and using a wedge/drift if your chuck uses a taper).
- Remove the quill retaining ring or retainer at the top of the quill/spindle area.
- Separate the quill and spindle; keep parts in order (spacers, washers, keys).
- Remove the spindle bearing(s) and inspect:
- Roughness when spun by hand
- Play (side-to-side movement)
- Heat discoloration or pitting
- Install new bearing(s) onto the spindle (press on the correct race; do not hammer on the bearing).
- Reinstall the spindle into the quill, then reinstall the retaining ring/retainer.
- Reassemble and test: quill travel should be smooth, and the chuck should seat firmly.
Quick diagnosis guide (what you’re fixing)
| Symptom | Most common cause | What to check first |
|---|---|---|
| Wobble/runout at the bit | Worn bearing or bent spindle | Bearing play, spindle straightness |
| Grinding noise | Dry or failing bearing | Bearing roughness |
| Chuck falls off | Dirty/damaged taper | Clean taper, inspect for nicks |
| Quill sticks | Burrs, dirt, misalignment | Quill bore cleanliness, return spring tension |
Why it matters
A worn spindle or bearing on a drill press can cause runout, oversized holes, chatter, and premature bit wear. Fixing the spindle assembly restores accuracy and reduces stress on the motor and pulleys.
Getting the right replacement parts
For Craftsman 14921331, match parts by the exact model number and the spindle or bearing dimensions you remove from the tool. We recommend searching by model first, then confirming measurements before ordering from Sears PartsDirect.

What are the parts of the drill press?
On the Craftsman 14921331 drill press, the main parts are the base, column, head (motor and pulleys), table and table clamp, quill and spindle, chuck/arbor, and the on/off switch. These components work together to support the workpiece and drive the bit straight and consistently.
Main drill press components (what each one does)
- Base: Supports the entire drill press; provides stability and a mounting surface.
- Column: Vertical post that supports the head and table; keeps alignment rigid.
- Head: Houses the drive system (motor, pulleys/belt) and the quill feed mechanism.
- Table and table clamp: Supports the workpiece; adjusts up/down on the column and locks in place.
- Quill and spindle: The quill moves up/down; the spindle rotates and drives the chuck.
- Chuck (and arbor, if used): Holds the drill bit or accessory.
- Feed handles and depth stop: Controls drilling pressure and sets repeatable hole depth.
Quick reference: part name vs. what to check when something feels “off”
| If you notice this symptom | Most likely area to inspect | Common cause |
|---|---|---|
| Bit wobbles or holes are oversized | Chuck, arbor, spindle | Loose chuck, dirty taper, worn chuck |
| Table slips or rotates during drilling | Table clamp, column | Clamp not tightened, worn clamp surfaces |
| Drill won’t return smoothly after a hole | Quill return spring, quill | Spring tension off, debris in quill travel |
| Speed seems wrong or squeals | Head (belt/pulleys) | Belt tension, pulley alignment, worn belt |
Why it matters
Knowing the names and roles of the base, column, head, table, and quill helps you troubleshoot faster and order the correct replacement part the first time, especially for alignment issues (runout), slipping tables, and feed problems.
Parts lookup tip for model 14921331
When you search parts, match the model number 14921331 exactly and use the diagram callouts to confirm you are selecting the correct assembly (head, table support, quill/spindle area). If you need to broaden your search beyond the parts list, use Sears PartsDirect.

Where is the model number on a Craftsman drill press?
On the Craftsman drill press model 14921331, the model number is typically printed on a data plate (or sticker) attached to the base near the column. Use that full model number when you look up diagrams, match replacement parts, or confirm compatibility on Sears PartsDirect.
Where to look on the drill press
Check these common label locations in this order:
- Base casting near the column (most common spot)
- Back side of the column (lower section)
- Head assembly (rear or side of the motor housing)
- Underside or rear edge of the base (if the press is bench-mounted)
- Inside the belt cover (some versions place an ID label there)
Tips to read the plate correctly
Dirt, oil, and surface rust can hide the characters. We recommend:
- Wipe the plate with a rag and a mild degreaser
- Use a flashlight at a low angle to make stamped numbers stand out
- Take a close-up photo and zoom in to read worn text
- Write down the full model number exactly as shown (including any dashes)
Why it matters
The model number identifies the exact Craftsman build and parts breakdown. That prevents ordering the wrong items when you are troubleshooting common drill press issues like belt slip, chuck wobble, switch problems, or quill return spring concerns.
Quick checklist: what to capture
| What to record | Example | Why we use it |
|---|---|---|
| Model number | 14921331 | Matches the correct parts list and diagrams |
| Serial number (if present) | Varies | Helps distinguish production runs |
| Motor nameplate info | HP/amps/volts | Helps when diagnosing power or start issues |
