You can remove a snow blower auger in about an hour with basic tools. Learning how to remove snow blower auger parts is key for fixing jams or replacing worn blades.
It might seem hard at first. But I’ve done this many times on my own machine. It gets easier once you know the steps.
You need a few simple tools. A socket set and some wrenches will do the job. A clean workspace helps a lot too.
This guide will walk you through the whole process. I’ll show you how to remove snow blower auger safely. You’ll save money on repair bills.
What You Need Before You Start
Gather your tools first. This makes the job go much smoother. You don’t want to stop halfway to find a tool.
You’ll need a socket set. A 1/2-inch drive set works best for the big bolts. You might need metric and standard sizes.
Get some wrenches too. An adjustable wrench can help with tricky spots. A pair of pliers is good for pulling pins.
Have a clean space ready. Put down a tarp or cardboard. This catches any grease or old parts that fall off.
Wear safety glasses. Little bits of metal can fly when you’re working. Gloves protect your hands from sharp edges.
Get your owner’s manual. It has a parts diagram for your model. This shows how everything fits together.
Step 1: Disconnect the Spark Plug Wire
Safety comes first every single time. This step stops the engine from starting by accident. It’s the most important rule.
Find the spark plug on your engine. It’s usually near the top. A thick wire runs to it from the ignition coil.
Pull the boot off the spark plug. You might need to twist it a little. Set the wire aside where it can’t touch the plug.
I always do this before I touch any tools. It takes ten seconds. It could save you a serious injury.
The Occupational Safety and Health Administration says to always disconnect power before repair. This simple step follows their safety rules.
Now you can work safely. The machine won’t start even if someone pulls the cord. You’ve removed the main danger.
Step 2: Drain the Fuel from the Tank
Gas can spill when you tip the machine. This makes a big mess. It’s also a fire risk you don’t need.
Use a siphon pump or a clean container. Get most of the gas out of the tank. Leave just a little bit in the bottom.
Run the engine until it stops. This uses up the fuel in the carburetor. It prevents gumming up the small parts.
Let the engine cool down completely. Metal parts get very hot after running. You don’t want to burn your hands.
Some people skip this step. I never do. Spilled gas smells bad and ruins your work area.
It only takes a few minutes. It makes the whole job cleaner and safer. You’ll thank yourself later.
Step 3: Tip the Snow Blower Safely
You need to get to the auger housing. The easiest way is to tip the machine back. But you must do this the right way.
Never tip it on its side. Oil can leak into the cylinder. This causes big problems when you start it again.
Tip it back onto its handles instead. The engine stays upright this way. The oil stays where it belongs.
Put a soft pad under the handles. An old blanket or piece of carpet works. This protects the paint from scratches.
Make sure it’s stable before you let go. It shouldn’t rock or wobble. You don’t want it falling over while you work.
Now you can see the auger housing clearly. All the bolts and parts are easy to reach. The hard part is done.
Step 4: Remove the Shear Bolts or Pins
Look at where the auger connects to the shaft. You’ll see special bolts or pins there. These are called shear bolts.
They’re designed to break on purpose. If the auger hits something hard, these bolts snap. This protects the gearbox from damage.
Use the right size socket on these bolts. Turn them counter-clockwise to loosen. They might be tight from years of use.
If they’re really stuck, try some penetrating oil. Let it soak in for ten minutes. Then try turning the bolts again.
Keep all the parts you remove. Put them in a small container. You’ll need them when you put everything back.
Some models use cotter pins instead of bolts. Use pliers to straighten the bent ends. Then pull the pin out of the hole.
Step 5: Take Off the Auger Housing Bolts
The auger housing is the metal cover. It holds the auger in place. Several bolts go around the edge of this cover.
Start with one bolt and loosen it. Don’t take it all the way out yet. Just break it free from being stuck.
Do this for all the housing bolts. Go around in a circle pattern. This prevents the housing from warping or bending.
Now remove the bolts completely. Put them in your parts container. Keep them separate from the shear bolts.
Some bolts might be different lengths. Note where each one came from. A piece of cardboard with holes poked in it makes a good holder.
Label the holes with a marker. Write “front left” or “rear right”. This helps during reassembly.
Step 6: Separate the Auger from the Shaft
This is the main step in how to remove snow blower auger parts. The auger should now be loose on the shaft. But it might still be stuck.
Don’t hammer on the auger directly. You could bend the blades or damage the shaft. Use a rubber mallet instead.
Tap gently on the side of the auger. Turn it a little and tap again. Work your way around in a circle.
If it’s really stuck, use a gear puller. This tool applies even pressure. It pulls the auger straight off the shaft.
The Consumer Reports guide to small engine repair suggests using proper tools. This prevents damage to expensive parts.
Once it starts moving, slide it off completely. Set it on your work surface. Be careful of the sharp edges on the blades.
Step 7: Inspect the Auger and Shaft
Now that you know how to remove snow blower auger, check the parts. Look at the auger blades first. Are they bent or cracked?
Check the cutting edges. They should be sharp and even. Dull edges don’t throw snow well.
Look at the center hole of the auger. Is it worn or egg-shaped? This causes wobbling when it spins.
Check the shaft it slides onto. Look for rust or deep grooves. A damaged shaft needs replacement too.
Examine the gearbox where the shaft comes out. Is there any oil leaking? Do the gears look clean and undamaged?
This inspection tells you what needs fixing. You might just need new shear bolts. Or you might need a whole new auger.
Common Problems You Might Find
Bent auger blades are very common. They happen when you hit a rock or curb. The auger can’t spin true when bent.
Worn shear bolts are another issue. They get thin in the middle from stress. Replace them even if they look okay.
Rust on the shaft makes removal hard. It seizes the auger in place. Clean it well before putting things back.
Missing or damaged paddles affect performance. The snow doesn’t get thrown far. Replacement paddles bolt on easily.
The National Institute for Automotive Service Excellence notes that corrosion causes most seizure problems. A wire brush cleans rust off well.
Knowing these common issues helps. You can spot them during your inspection. Then you know what parts to order.
How to Clean the Auger Housing
While the auger is out, clean the housing. Years of packed snow and ice build up inside. This reduces how much snow you can move.
Use a putty knife or stiff brush. Scrape off all the old debris. Get into the corners where snow packs tight.
Check the scraper bar at the bottom. This is the metal edge that touches the ground. It should be even and not worn down.
If it’s worn, now is the time to replace it. A new scraper bar improves performance a lot. It gets closer to the ground.
Look for any cracks in the housing. These usually happen from hitting something hard. A cracked housing needs welding or replacement.
Wipe everything down with a rag. Remove all the grease and dirt. A clean housing makes reassembly easier.
Reassembly – Putting It All Back Together
Clean the shaft with a wire brush first. Remove all rust and old grease. A smooth shaft lets the auger slide on easily.
Apply a thin coat of grease to the shaft. Use white lithium grease if you have it. This prevents rust and makes future removal easier.
Slide the auger onto the shaft. Make sure it goes all the way on. It should sit flush against the gearbox housing.
Line up the holes for the shear bolts. You might need to turn the auger a little. Get them perfectly aligned.
Install new shear bolts. Don’t reuse the old ones. Tighten them just until they’re snug, not super tight.
According to Snow & Ice Management Association, proper bolt torque is critical. Over-tightening defeats the shear protection feature.
Final Steps Before Testing
Reinstall the auger housing cover. Put all the bolts back in their places. Tighten them evenly in a star pattern.
Check that everything rotates freely. Turn the auger by hand. It should spin smoothly without rubbing.
Reconnect the spark plug wire. Push it onto the plug until it clicks. Make sure it’s fully seated.
Add fresh fuel to the tank. Use the type recommended in your manual. Old gas causes starting problems.
Start the engine and let it warm up. Listen for any unusual noises. The auger should not engage yet.
Engage the auger briefly. Just for a second to check rotation. Everything should work smoothly now.
When to Call a Professional
Some jobs are too big for DIY. If the gearbox is damaged, you need a pro. Gearbox repair requires special tools and knowledge.
If the engine has problems too, get help. Maybe it won’t start or runs poorly. Fix the engine issues first.
Electric start systems can be tricky. If you’re not comfortable with wiring, don’t risk it. One wrong connection can fry the system.
The Small Engine Suppliers Association has a technician directory. You can find a qualified repair shop near you.
Sometimes the cost of parts is too high. If the auger, shaft, and housing all need replacement, a new machine might be cheaper. Get a quote first.
Knowing your limits is smart. I’ve called for help on complex jobs. It’s better than making things worse.
