If your Kirby vacuum has lost its suction or the brush roll has stopped spinning, the problem is often a worn or broken belt. Knowing how to put a belt on a Kirby vacuum is a simple repair that can save you time and money. This guide will walk you through the entire process, step-by-step, for various Kirby models. You’ll be back to cleaning in no time.
How to Put a Belt on a Kirby Vacuum
Before you start, you’ll need a few things. First, make sure you have the correct replacement belt for your specific Kirby model. Using the wrong belt can cause damage. You’ll also need a screwdriver, usually a Phillips head, and a clean workspace. It’s a good idea to unplug the vacuum completely before doing any work on it.
Identifying Your Kirby Model and Belt
Kirby has made many models over the years. The belt path is similar for most, but it’s crucial to get the right part. You can find your model number on a sticker or plate, usually located on the back of the vacuum or underneath the bag compartment. Once you have the model number, you can order a genuine Kirby belt or a compatible one from a reputable supplier.
- Common Models: Sentria, Avalir, Heritage, G-series, and Diamond Edition all use a similar belt routing method.
- Belt Types: Most modern Kirbys use a single, continuous belt that loops around the motor pulley and the brush roll.
Step-by-Step Belt Replacement Guide
Follow these steps carefully. If you hit a snag, just take a breath and review the previous step.
Step 1: Safety First and Access the Brush Roll
Unplug the vacuum cord from the wall outlet. Lay the vacuum on its back so you can see the bottom plate. Locate the screws holding the bottom plate or the brush roll cover in place. There are usually four to six screws. Use your screwdriver to remove them and set them in a safe place where they won’t get lost.
Step 2: Remove the Old Belt
Once the plate is off, you’ll see the brush roll and the old belt. The belt will be stretched around the brush roll at one end and around a small motor pulley at the other. Carefully slide the belt off the brush roll first. It might be tight, so you may need to gently twist it off. Then, pull it off the motor pulley. Inspect the old belt for breaks, cracks, or glazing (a shiny, hardened appearance).
Step 3: Clean the Area
While the plate is off, this is a perfect time to clean. Hair, string, and debris often wrap around the ends of the brush roll, which can cause the belt to wear out faster and strain the motor. Use scissors or a seam ripper to carefully cut away any tangled material. You can also wipe out the inside of the chamber with a dry cloth.
Step 4: Install the New Belt
Take your new belt. First, loop it onto the motor pulley. This is the smaller, metal pulley connected to the vacuum’s motor. Make sure it’s seated securely in the groove. Then, stretch the other end of the belt over the brush roll. You’ll need to pull it over one side of the brush roll and then work it onto the center shaft. It requires a bit of stretching, but be gentle to avoid tearing the new belt.
- Tip: Some people find it easier to put the belt on the brush roll first, then onto the motor pulley. Do whichever feels more natural to you.
Step 5: Reassemble the Vacuum
Before you put the plate back on, manually spin the brush roll with your hand. It should turn freely and the belt should track smoothly on the pulleys. If it looks good, align the bottom plate back onto the vacuum. Insert and tighten all the screws you removed earlier. Don’t over-tighten them, as you could strip the plastic threads.
Step 6: Test Your Work
Plug the vacuum back in. Turn it on and listen. The brush roll should spin quietly and efficiently. You can flip the vacuum over (carefully, while it’s running) to visually confirm the brush is spinning. If it’s not spinning, turn it off and unplug it immediately. Re-check that the belt is properly seated on both pulleys.
Troubleshooting Common Issues
Sometimes, things don’t go perfectly on the first try. Here are some common problems and their solutions.
- Brush Roll Won’t Spin: The belt is likely not on the motor pulley correctly, or the brush roll is jammed with debris you missed. Double-check both.
- Burning Smell: A new belt may have a slight odor for a minute, but a strong burning smell means the belt is too tight or the brush roll is obstructed. Turn off the vacuum and investigate.
- Loud Noise: This could indicate the belt is rubbing against something or that the brush roll bearings are worn. Ensure the belt is riding in the center of the pulleys.
- Belt Breaks Quickly: If a new belt breaks soon after installation, there may be a sharp edge on a pulley or a misalignment. Also, check that you’re using the correct belt size; an ill-fitting belt will fail fast.
Preventive Maintenance Tips
Regular care can make your Kirby belt last much longer. A little upkeep goes a long way in preventing sudden breakdowns.
- Clean the Brush Roll Regularly: Make a habit of removing the bottom plate every month or two to cut away wrapped hair and strings.
- Check Belt Tension: When you clean the brush roll, glance at the belt. If it looks frayed, cracked, or loose, it’s time for a replacement.
- Clear the Path: Pick up large objects like coins and paperclips before vacuuming. These can jam the brush roll and put stress on the belt.
- Store Properly: When not in use, store the vacuum in a cool, dry place. Avoid leaving it in extreme heat or cold, which can degrade the rubber in the belt.
When to Call a Professional
While belt replacement is a common DIY task, there are times when you might need help. If the motor pulley itself is damaged or won’t spin, that’s a more serious repair. If you’ve followed all steps and the brush roll still doesn’t turn, there could be an issue with the motor or the drive mechanism. In these cases, contacting an authorized Kirby service center is the best course of action. They have the tools and expertise to diagnose and fix complex problems.
Frequently Asked Questions (FAQ)
How often should I replace the belt on my Kirby vacuum?
It depends on how frequently you use your vacuum. For an average home, checking the belt every 6 months and replacing it once a year is a good rule of thumb. If you have long hair or pets, you may need to replace it more often.
Can I use any vacuum belt on my Kirby?
No, it’s not recommended. Kirby belts are designed for the specific tension and pulley size of their machines. Using a generic or incorrect belt can lead to poor performance, extra noise, and potentionally damage the motor or brush roll.
Where can I buy a replacement Kirby vacuum belt?
You can purchase genuine Kirby belts directly from Kirby company websites, through authorized dealers, or from reputable online retailers like Amazon. Always have your model number ready to ensure you get the correct part.
Why does my Kirby vacuum belt keep breaking?
Frequent breakage is usually a sign of another problem. Common causes include a jammed or difficult-to-spin brush roll, a misaligned pulley, or using the wrong belt size. Excessive debris buildup can also cause extra strain.
Is it hard to change a Kirby belt yourself?
Not at all! For most people, changing a Kirby vacuum belt is a straightforward task that takes about 10-15 minutes. With a screwdriver and the right replacement belt, you can usually complete the job by following simple instructions like the ones in this article.
What tools do I need to replace the belt?
Typically, you only need a Phillips head screwdriver to remove the bottom plate. Some older models might require a different screwdriver type, but a Phillips is the most common tool needed for this repair.
