What is the typical lifespan of a gas snowblower?
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.
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.
| 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 |
- 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.
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.
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.

How to find snowblower model number?
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.
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)
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 |
- 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.
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.

Is sae 30 the same as 5W30 for snowblower?
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.
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
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 |
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
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.
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.

Is it cheaper to repair or replace a snowblower?
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.
- 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
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 |
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.
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.
