What are the main parts of a belt sander?
On the Craftsman belt and disc sander model 113226423, the main belt-sanding parts are the abrasive sanding belt riding on a drive pulley (powered by the motor/drive system) and an idler pulley that keeps the belt tracked and tensioned; the work is supported by the belt sanding table and backstop (see the owner's manual).
- Sanding belt (the abrasive belt that does the cutting)
- Drive pulley and drive shaft (turns the belt)
- Idler pulley (guides the belt and helps maintain tension)
- Belt tension spring (keeps proper belt tension)
- Belt sanding table (supports the workpiece at the belt)
- Backstop (supports the workpiece so it is not “freehand”)
- Guards and sanding plate (help prevent contact and entanglement)
| Part | What it does | Why it matters |
|---|---|---|
| Drive pulley | Powers belt movement | Determines sanding speed and consistency |
| Idler pulley | Guides belt and helps tracking | Reduces belt wandering and edge damage |
| Belt tension spring | Maintains belt tension | Prevents slipping and uneven sanding |
| Belt sanding table/backstop | Supports the workpiece | Improves control and safety |
These items are part of safe operation, not optional add-ons.
- Support the workpiece with the backstop or worktable (except certain curved work at the outer end of the belt)
- Do not operate with the sanding plate and/or guard removed
- Shut off the switch and unplug before installing or removing accessories
- Use recommended accessories for the sander
- Sand wood or wood-like materials only (this model is designed for that)
Knowing the drive pulley, idler pulley, and tensioning parts helps you diagnose common issues like belt slipping, poor tracking, vibration, or uneven sanding. Knowing the table, backstop, and guards helps you set up the tool for controlled, repeatable sanding.

What are the most common issues with 113226423?
The most common issues we see with the Craftsman 113226423 belt and disc sander are tracking problems on the belt, poor sanding performance from worn abrasives, vibration from misalignment or loose hardware, and power problems related to the switch, cord, or internal wiring. Use the owner's manual for the correct adjustment points and safety steps.
- Belt won’t stay centered: tracking needs adjustment; belt may be stretched or installed incorrectly.
- Sanding is slow or burns wood: abrasive is worn, clogged, or the wrong grit for the job.
- Excessive vibration or noise: loose fasteners, worn bearings, out-of-true disc, or misaligned pulleys/rollers.
- Sander won’t start: bad outlet, damaged power cord, faulty switch, or a wiring connection issue.
- Disc or belt slips: tension is low, drive surfaces are dusty, or a drive component is worn.
- Unplug the sander and remove dust buildup from the belt area, disc guard, and motor vents.
- Confirm the belt is installed in the correct direction (if marked) and seated on the rollers.
- Set belt tracking and belt tension to the manual’s procedure.
- Check the platen/table and guards for looseness; tighten mounting bolts evenly.
- If it’s a power issue, inspect the cord for cuts and test the switch and continuity with a meter.
| Symptom | Most likely cause | First action |
|---|---|---|
| Belt walks off | Tracking out of adjustment | Adjust tracking per manual |
| Vibration | Loose hardware or misalignment | Tighten, then re-check alignment |
| Won’t start | Switch/cord/wiring issue | Verify outlet, then test switch |
| Burning | Wrong grit or clogged abrasive | Change belt/disc; use coarser grit |
A belt and disc sander that is out of tracking or vibrating can ruin workpieces and wear out rollers, bearings, and the motor faster. Keeping tracking, tension, and dust control in spec improves cut quality and extends tool life.
