Yes, you can do it yourself – learning how to change belts on a Craftsman snowblower is a key skill for winter upkeep. It saves you money and gets your machine ready for the next storm.
When a belt wears out, your snowblower won’t work right. It might not move or throw snow like it should. This leaves you stuck with a big job and a broken tool.
I’ve changed these belts many times over the years. It seems hard at first, but it’s really just a few simple steps. You need some basic tools and a bit of patience.
This guide will walk you through the whole process. I’ll show you how to change belts on a Craftsman snowblower safely and correctly. Let’s get your machine running again.
What You Need Before You Start
Gather your tools first. This makes the job go a lot smoother. You don’t want to stop halfway to find something.
You’ll need a set of wrenches and sockets. A socket set with a ratchet is best. You might also need a screwdriver or two.
Get the right replacement belt for your model. Check your owner’s manual for the part number. You can also find it online or at a parts store.
Have a clean work area ready. A garage floor or driveway works fine. Put down a tarp or cardboard to keep parts clean.
Wear safety glasses for this job. Little bits of dirt and metal can fly around. Gloves are a good idea too to protect your hands.
Take a picture of the belt setup before you take it apart. This helps you remember how everything goes back together. Your phone camera is perfect for this.
Finding the Right Belt for Your Model
Not all belts are the same. You need the exact one for your snowblower. The wrong belt won’t fit or work right.
Look for the model number on your machine. It’s usually on a sticker or metal plate. You can find it near the engine or on the frame.
Use that number to search for parts. The Craftsman website has a parts lookup tool. Local hardware stores can help you find it too.
There are often two main belts on a snowblower. One drives the wheels for movement. The other drives the auger to throw snow.
When you learn how to change belts on a Craftsman snowblower, you need to know which one is bad. A broken drive belt means the wheels won’t turn. A broken auger belt means the auger won’t spin.
It’s smart to change both belts if one is worn out. The other is probably old too. Doing both now saves you from doing this job again soon.
Step-by-Step Guide to Belt Replacement
First, make sure the engine is off and cool. Disconnect the spark plug wire too. This stops the engine from starting by accident.
You need to get to the belt covers. These are metal plates held on by bolts. Use your socket set to take these bolts out.
Set the bolts in a safe place. I like to use a small cup or tray. This keeps them from getting lost in the grass or snow.
Look at how the old belt is routed. Note which pulleys it goes around. Your photo from earlier will help a lot here.
Loosen any tension on the belt. There is often an idler pulley or a spring. You might need to push or pull this to get slack.
Slip the old belt off the pulleys. It might be tight or stuck. Wiggle it gently until it comes free.
Compare the old belt to the new one. They should be the same width and length. A big difference means you have the wrong part.
Route the new belt exactly like the old one. Follow the path you noted or your photo. This is the most important part of how to change belts on a Craftsman snowblower.
Make sure the belt sits right in the pulley grooves. It shouldn’t be twisted or pinched. A twisted belt will wear out fast and might break.
Check the belt tension. There should be a little bit of give. You don’t want it too tight or too loose.
Put the belt covers back on. Tighten all the bolts snugly. Don’t over-tighten them or you might strip the threads.
Reconnect the spark plug wire. You’re now ready for a test run. Do this without snow first to make sure it works.
Common Problems and How to Fix Them
The belt keeps falling off after you put it on. This usually means the pulleys are not lined up right. Check for bent pulley brackets or worn bearings.
The new belt seems too tight or too loose. The tension adjustment might be set wrong. Look for the adjustment bolt or spring and move it.
You hear a squealing sound when the engine runs. This often means the belt is too loose. It’s slipping on the pulleys instead of gripping.
A belt that wears out very fast has a problem. Something is causing extra friction. Check for rusted pulleys or something rubbing against the belt.
The auger turns but the wheels don’t move. This points to a bad drive belt. You need to learn how to change belts on a Craftsman snowblower’s drive system.
The wheels move but the auger doesn’t spin. This is the auger belt. It’s a different belt in a different spot on the machine.
You can’t find the model number on your snowblower. Look for any numbers stamped into the metal. Older models might have it near the engine mounting plate.
When to Change Your Snowblower Belts
Change belts before they break completely. A worn belt has cracks on the inside. You might also see frayed edges or glazing on the surface.
If your snowblower is more than five years old, check the belts. Rubber gets hard and brittle with age. It loses its grip and can snap.
After a very heavy snow season, look at the belts. Lots of use wears them down faster. It’s good to check them each fall before winter.
Hearing strange noises is a warning sign. Squealing, slapping, or grinding sounds mean trouble. Don’t ignore these sounds hoping they’ll go away.
Seeing black dust around the belt area is a clue. This is rubber dust from a wearing belt. It means the belt is rubbing and breaking down.
The machine acts sluggish or weak. It might struggle to move through deep snow. This could be a slipping belt that needs more tension or replacement.
Learning how to change belts on a Craftsman snowblower before you need to is smart. You won’t be stuck during a storm. You’ll have the parts and knowledge ready.
Tools That Make the Job Easier
A good socket set is your best friend here. The Occupational Safety and Health Administration says using the right tool for the job prevents accidents. Don’t try to use pliers on a bolt meant for a socket.
A magnetic parts tray keeps bolts from rolling away. It’s a small thing that saves a lot of frustration. You can find these at any auto parts store.
A work light or headlamp helps you see in dark spots. The inside of a snowblower can be shadowy. Good light lets you see what you’re doing.
A floor jack or some wood blocks can lift the machine. You need to get under it sometimes. Make sure it’s stable so it doesn’t fall on you.
A belt tension gauge takes the guesswork out. It tells you if the belt is tight enough. This tool is optional but very helpful.
A simple notepad and pen let you draw the belt path. If you don’t trust your memory or phone, draw it. This is part of learning how to change belts on a Craftsman snowblower the right way.
Keep your owner’s manual handy. It has diagrams and specs for your exact model. This is the best guide you can have.
Safety Tips You Must Follow
Always disconnect the spark plug before you start. This is the number one safety rule. The engine cannot start if the plug wire is off.
Let the engine cool down completely. Hot metal can burn your skin. Exhaust parts stay hot for a while after running.
Wear eye protection at all times. Rust flakes and dirt can fall into your eyes. Safety glasses are cheap and effective.
Don’t put your fingers near moving parts during a test. Even with the spark plug off, parts can move if you turn them by hand. Keep your hands clear.
Work on a flat, stable surface. Don’t try to fix your snowblower on a hill or slope. It could roll or tip over.
Use jack stands if you lift the machine. Never rely on just a jack to hold it up. Jack stands are made to hold weight safely.
According to the Consumer Product Safety Commission, proper maintenance keeps equipment safe. Knowing how to change belts on a Craftsman snowblower is part of that maintenance.
What to Do If You Get Stuck
Take a break if you feel frustrated. Come back with a clear head. Forcing something usually makes it worse.
Look for online videos for your model. Many people post repair tutorials. Seeing someone else do it can help a lot.
Call a local small engine repair shop for advice. They might give you a tip over the phone. Some shops are happy to help DIYers.
Join a forum for snowblower owners. These groups share knowledge and tips. You can ask questions and get answers from experienced people.
If the job seems too big, it’s okay to hire a pro. Your safety is more important than saving money. A pro can do it fast and guarantee the work.
Remember that every snowblower is a bit different. Yours might have a unique setup. The basic steps for how to change belts on a Craftsman snowblower are the same, but details vary.
Don’t throw away the old belt until the new one works. You might need it for reference or in case the new belt is wrong. Keep it nearby just in case.
Keeping Your New Belts in Good Shape
Store your snowblower in a dry place. Dampness makes belts rot and rust pulleys. A garage or shed is much better than outside.
Check belt tension a few times each season. Vibration can loosen bolts over time. A quick check takes just a minute.
Keep the belt area clean of debris. Grass, leaves, and dirt get inside and wear on the belt. Blow it out with air or use a brush.
Don’t use belt dressing sprays. These are sticky and attract more dirt. A clean, proper-tensioned belt doesn’t need extra help.
Lubricate pulley bearings if your model has them. The U.S. Department of Energy notes that proper lubrication reduces friction and wear. This makes everything last longer.
Listen for changes in sound when you use it. Your ears are good tools for spotting problems early. A new sound often means something is wrong.
Learning how to change belts on a Craftsman snowblower is just the start. Good care keeps them working for many seasons. It’s worth the little bit of extra effort.
