Milwaukee Band Saw Rubber Belt: Model Identification, Setup, and Common Repairs
You own a Milwaukee band saw and the rubber drive belt needs replacing. The rubber drive belt connects the motor to the blade drive wheel. You need to know how to identify the correct belt, replace it, and troubleshoot common problems.
The rubber drive belt on a Milwaukee band saw connects the motor to the blade drive wheel. It transfers power from the motor to the wheel that drives the blade. Over time, the belt can stretch, crack, or break, causing the saw to lose power or stop cutting.

- Corded models: Most corded models have a replaceable drive belt.
- Older battery models: Some older brushed motor models may have a belt.
- Check the manual: The manual will show if the saw has a replaceable belt.
- Contact Milwaukee: Call Milwaukee customer service with the model number.
Belt Types
V-Belt
The most common type on Milwaukee corded band saws.
Description: A V-shaped belt that runs in V-shaped grooves on the motor pulley and drive wheel pulley. Material: Rubber or synthetic rubber. Lifespan: 2 to 5 years with regular use.
Toothed Belt
Some models may use a toothed (timing) belt.
Description: A belt with teeth that mesh with toothed pulleys. Material: Rubber with fiberglass or steel reinforcement. Lifespan: 3 to 7 years with regular use.
Signs You Need a New Belt
1. Saw Loses Power Under Load
If the saw slows down or stops when cutting, the belt may be slipping.
2. Burning Smell
A slipping belt generates heat and produces a burning rubber smell.
3. Visible Damage
Check the belt for cracks, fraying, or missing chunks.
4. Saw Will Not Cut
If the motor runs but the blade does not move, the belt may be broken.
5. Excessive Vibration
A worn or stretched belt can cause vibration.
6. Noise
A squealing or chirping noise may indicate a slipping or worn belt.
How to Replace the Belt
Step 1: Identify the Correct Belt
- Find the model number on your saw.
- Look up the belt part number in the parts diagram.
- Order the belt from Milwaukee, eReplacementParts, Amazon, or eBay.
Step 2: Disassemble the Saw
- Unplug the saw (or remove the battery).
- Remove the blade guard.
- Remove the side cover to access the belt.
- Note the belt routing for reassembly.
Step 3: Remove the Old Belt
- Loosen the motor mounting bolts to create slack in the belt.
- Remove the old belt from the pulleys.
Step 4: Install the New Belt
- Place the new belt on the pulleys.
- Tighten the motor mounting bolts to tension the belt.
- Check the belt tension. The belt should deflect about 1/4 inch with moderate finger pressure.
- Check that the belt is properly seated in the pulley grooves.
Step 5: Reassemble the Saw
- Replace the side cover.
- Replace the blade guard.
- Plug in the saw (or install the battery).
Step 6: Test the Saw
- Turn on the saw.
- Listen for unusual noises.
- Check that the blade runs smoothly.
- Make a test cut to verify proper operation.
