Craftsman 247887550 22" snow thrower Parts

A typical gas snowblower lasts 10 to 20 years with regular maintenance. For the Craftsman 247887550 specifically, the owner's manual lists an average useful life of 7 years or 60 operating hours, after which we recommend annual inspections and staying current on belts, oil, and wear items.

What “lifespan” means for model 247887550

The manual’s “average useful life” is a safety and usage benchmark (hours and years). Many owners get longer service life by keeping the engine maintained and replacing normal-wear parts on schedule.

Typical ranges you can use

Measure	Typical for gas snowblowers	Craftsman 247887550 manual reference
Service life (years)	10 to 20 years	7 years average useful life
Usage life (hours)	Often 100+ hours with care	60 hours average useful life

What extends a gas snowblower’s life the most

• Change engine oil after the first 5 hours, then about every 50 hours.
• Check V-belts about every 50 hours; replace if frayed, cracked, or glazed.
• Keep shear pins correct; use the proper shear pin so the gearbox is protected.
• Store fuel correctly for off-season storage (use fuel stabilizer for short-term storage).
• Inspect fuel lines and fittings for cracks or leaks and replace as needed.

Why it matters

A snowblower can “run” but still be unsafe or unreliable if belts slip, fuel lines leak, or the auger system is stressed. Following the maintenance schedule helps your Craftsman 247887550 throw snow consistently and reduces expensive repairs.

Parts that commonly affect longevity

If performance drops (poor throwing, auger not engaging, or drive slipping), these are common maintenance parts to check and replace as needed:

• Craftsman snowblower shear pin 738-04124A
• Mtd snowblower auger drive belt 754-04014
• Snowblower ground drive belt 754-04013

You can order replacement parts for your Craftsman 247887550 from the parts list for this model, or search by model number on Sears PartsDirect.

Your snowblower model number is on the product identification label attached to the machine frame. For Craftsman model 247887550 (22-inch snow thrower), check the frame near the engine, the rear base between the wheels, or the auger housing; confirm the format in the owner's manual.

Where to look on a Craftsman snowblower

Use a flashlight and wipe off packed snow, salt, and grime so the label is readable.

• Frame near the engine (side of the unit, close to the engine mounting area)
• Rear of the base between the wheels (common spot on many walk-behind units)
• Auger housing (outer housing area near the front)
• Handle support area (sometimes on the lower handle/frame junction)
• Stamped metal (less common, but some units have numbers stamped into the frame)

Model number vs. engine model number (why you may need both)

Your Craftsman snowblower has a snow thrower model number (used for chassis parts like belts, augers, and shear pins) and an engine model number (used for engine-specific parts).

Number type	What it identifies	Examples of parts it helps match
Snowblower model number (example: 247887550)	The complete machine (auger housing, drive system, controls)	Auger drive belt, ground drive belt, shear pins, chute parts
Engine model number (often on engine shroud/recoil area)	The engine itself	Carburetor, ignition coil, recoil starter, fuel tank

Tips to record it correctly

• Copy the full model number exactly (all digits, no spaces).
• Take a photo of the label before ordering parts.
• If the label is damaged, compare the machine’s major assemblies (auger housing size, chute style, drive controls) to the diagrams in the owner's manual.
• When ordering, start with the parts list for your model, then use Sears PartsDirect if you need to search by model number again.

Why it matters

The model number is the fastest way to get the right Craftsman snowblower parts the first time. Even small differences between similar 22-inch snow throwers can change belt lengths, cable styles, and auger hardware.

No. On the Craftsman 247887550 22" snow thrower, SAE 30 and 5W-30 are not the same; our operator’s manual specifies 5W-30 engine oil (20 oz capacity) because it flows better for cold-weather starting and lubrication. See the oil spec in the owner's manual.

What to use in this model (247887550)

The manual for this snowblower calls out these engine-oil details:

• Oil type: 5W-30
• Oil capacity: 20 ounces
• Check oil level: before each use, on a level surface with the engine stopped
• Fill range: keep oil between the dipstick “L” and “H” marks
• Avoid overfill: overfilling can cause smoking, hard starting, or spark plug fouling

Why SAE 30 is different from 5W-30

SAE 30 is a single-weight oil; 5W-30 is a multi-grade oil designed to flow like a lighter oil when cold and protect like a 30-weight when warm.

Oil type	Cold start flow	Best use case	Snowblower impact
SAE 30	Thick in cold temps	Warm-weather operation	Harder starting, slower lubrication
5W-30	Flows well in cold temps	Cold-weather operation	Easier starting, faster protection

If you already put SAE 30 in the engine

We recommend switching to the specified oil before regular use in freezing conditions.

• Run the engine briefly only if needed to warm the oil slightly (do not operate under load)
• Shut off the engine and let it cool enough to work safely
• Drain the oil and refill with 5W-30 to the proper dipstick level
• Recheck the level after a short run and top off if needed

Why it matters

Snowblower engines depend on fast oil flow at startup. Using the specified 5W-30 helps reduce cold-start wear and makes starting easier during winter operation.

Parts and supplies

If hard starting continues after correcting the oil, common tune-up items include the ignition system and fuel system components. You can find model-matched replacement parts for Craftsman 247887550 on the parts list for this model, or search by model number on Sears PartsDirect.

For a Craftsman 247887550 22-inch snow thrower, it’s cheaper to repair when the fix is a normal wear item (belt, shear pin, skid shoes) and the total repair cost stays under about half the price of a comparable new machine. Replace when the engine or transmission needs major work or repairs keep repeating.

Quick decision checklist

• Repair if the problem is a maintenance item: belts, shear pins, skid shoes, shave plate, spark plug
• Repair if the machine still starts easily and throws snow strongly after basic service
• Replace if the engine has low power, heavy smoke, or severe internal damage
• Replace if the transmission or gearbox is failing (costly, labor-heavy repairs)
• Replace if the auger housing or frame is badly bent or cracked
• Replace if you are facing multiple major repairs in the same season

Typical repair costs vs. replacement value

Use this as a practical way to decide what makes sense for your budget.

Issue type	Common examples on snowblowers	Usually best choice	Why
Wear and protection parts	Shear pins, belts, skid shoes	Repair	Low cost, restores performance fast
Fuel and starting problems	Carburetor issues, recoil starter problems	Repair first	Often a single-part fix
Major drivetrain or engine	Transmission, internal engine damage	Replace	High parts cost plus labor

Model-specific examples (247887550)

These are common, cost-effective repairs we see on this model:

• If the auger stops turning after hitting ice or a foreign object, the shear pins are designed to break to protect the gearbox; replace with the correct OEM shear pin. Use owner's manual.
• A worn auger belt can cause weak or intermittent auger engagement; replacing the belt is typically a good repair choice. Consider mtd snowblower auger drive belt 754-04014.
• If the machine will not move well, a worn ground drive belt is a common cause; consider snowblower ground drive belt 754-04013.

Why it matters

Repairing the right problem keeps your snowblower safe and prevents expensive damage. For example, using the correct shear pin protects the auger gearbox; the manual specifically warns not to substitute other fasteners.

If you decide to replace, you can still use this model number (247887550) to compare parts costs and availability, then shop by model on Sears PartsDirect.
