Craftsman 247881731 snow thrower Parts

On the Craftsman snow thrower model 247881731, a bad auger belt usually shows up as poor snow-throwing performance (auger slows, stops, or slips under load) and visible belt damage like cracking, glazing, fraying, or missing chunks. A burning rubber smell is also a common warning sign.

Quick checks you can do safely

Before inspecting, shut the engine off, remove the key, and wait for all moving parts to stop. Then use these checks from the 247881731 operator's manual.

• Visual condition: cracks, frayed cords, shiny glazed surface, or chunks missing
• Slipping symptoms: auger turns with no load but stalls in heavy snow
• Noise or smell: squealing or a hot/burning rubber odor near the belt cover
• Engagement feel: auger control feels “soft” or inconsistent (often tied to cable tension)
• Snow discharge: snow dribbles out instead of being thrown with force

Belt vs. adjustment: what the symptoms mean

Sometimes the belt is fine, but the auger control cable is out of adjustment. Use this guide to narrow it down.

What you notice	More likely cause	What to do next
Belt looks shiny or has cracks	Worn belt	Replace the belt
Auger slips only under load	Belt stretched or glazed	Inspect belt and pulleys; replace if worn
Auger keeps moving after you release the lever	Cable too tight or misadjusted	Perform the auger control stop test and adjust cable
Auger will not move at all	Broken belt or other drive issue	Inspect belt first; then check shear pins and auger area

When replacement is the right call

If you see physical damage or consistent slipping, replacing the belt is the most reliable fix. For this model, the compatible replacement is the snowblower auger drive belt 256963.

Why it matters

A slipping auger belt reduces throwing distance, can overheat and fail suddenly, and can make the auger control feel unreliable. Catching belt wear early helps protect the pulleys, idler/brake components, and auger drive system.

A gas snowblower like the Craftsman 247881731 typically lasts 10 to 15 years with normal residential use and consistent maintenance. For this specific model, the operator guidance also notes an average useful life of 7 years or about 60 operating hours, after which annual inspections are recommended (see the 247881731 operator's manual).

What “life expectancy” means for the 247881731

Snowblowers can keep running well past the average useful life if wear items are replaced on time and the machine is stored correctly.

• Average useful life: 7 years or ~60 hours (inspection recommended after that)
• Typical real-world lifespan: 10 to 15 years with good care
• Biggest lifespan drivers: fuel quality, oil changes, belt condition, and corrosion control

Maintenance habits that extend lifespan

These are the most important things we recommend doing every season:

• Change engine oil on schedule and keep the oil at the correct level
• Use fresh fuel and avoid storing untreated gasoline in the tank
• Keep the auger and drive systems adjusted so belts do not slip
• Lubricate moving points (wheels, shafts, pivots) to prevent rust and binding
• Clean packed snow and salt residue off the housing after use
• Store the unit dry and protected during the off-season

Wear items that commonly determine “when it’s time”

Many snowblower problems are normal wear, not end-of-life. Replacing a few parts can restore performance.

Wear item	What you’ll notice	Typical fix
Auger drive belt	Auger slows, won’t throw well	Replace belt (example: snowblower auger drive belt 256963)
Skid shoes / shave plate	Scraping, poor clearing height	Replace or adjust
Shear pins	One auger stops turning	Replace with correct shear pins
Spark plug	Hard starting, rough running	Clean/gap or replace

Why it matters

Knowing the expected lifespan helps you decide whether to tune up, replace a belt, or schedule a deeper inspection. On the 247881731, staying ahead of fuel and belt maintenance is often the difference between a one-pull start and a no-start situation mid-storm.

Yes. For Craftsman snow thrower model 247881731, the operator’s manual specifies 5W-30 engine oil (minimum SF/SG), so using 5W-30 is the correct choice; SAE 30 is typically a warm-weather oil and can make cold starting harder.

What the manual for model 247881731 says

Our guidance for this exact model comes from the 247881731 operator’s manual. It calls out:

• Engine oil: 5W-30
• Oil classification: SF/SG minimum
• Check oil level before each use; do not overfill
• Change oil after the first 5 hours, then once a season or every 50 hours

5W-30 vs SAE 30 (practical differences)

Both oils protect the engine, but they behave differently in cold weather.

Oil type	Cold starting	Best use case	Typical snowblower fit
5W-30	Easier	Cold temps and winter operation	Recommended for 247881731
SAE 30	Harder	Warmer temps	Not ideal for winter starting

Best practices when switching oil types

If you are moving from SAE 30 to 5W-30 (or you are unsure what is in the crankcase now), we recommend:

• Drain and refill on a level surface with the engine off and cool
• Use a clean funnel and keep dirt out of the oil fill tube
• Verify the dipstick reading without screwing it in (as described in the manual)
• Do not overfill; overfilling can cause smoking, hard starting, or spark plug fouling
• Follow the seasonal/50-hour oil change interval

For a step-by-step walkthrough, see how to change snowblower oil video.

Why it matters

Using the correct viscosity helps your Craftsman 247881731 start reliably in freezing temperatures and keeps internal engine parts properly lubricated during warm-up and heavy snow loads.

On the Craftsman snow thrower model 247881731, the operator’s manual tells you to record the model and serial numbers, but it does not identify an exact sticker location on the machine. In practice, the model/serial tag is usually on the frame or rear area of the unit; confirm the number you find against the 247881731 operator's manual.

Where to check on a Craftsman snow thrower

With the engine OFF and cool, look for a model/serial label or stamped tag in these common areas:

• Rear frame area near the wheels or axle
• Handle support or lower handle mounting area
• Side of the main frame near the engine mounting plate
• Back or side of the auger housing frame (not on the rotating auger)
• Under the control panel area (less common)

Model number vs. engine model number

This matters because the snow thrower and the engine can have different identification numbers.

ID you find	What it’s used for	Example for this unit
Snow thrower model number	Matching chassis, auger, drive, and control parts	247881731
Engine model number	Matching engine-specific parts and tune-up items	MTD 952Z270-SUA

Tips if the tag is hard to read

• Clean the label gently with mild soap and water; dry completely
• Use a flashlight from the side to highlight faded print
• Copy the full model number and serial number exactly as shown
• If the label is missing, check for stamped numbers on the frame near where a label would mount

Why it matters

Using the correct 247881731 model number helps us match the right parts diagrams and compatible replacements for your Craftsman snow thrower.
