Craftsman 247889700 26" snow thrower Parts

A Craftsman snowblower like model 247889700 is typically designed to provide about 7 years of average useful life (or about 60 hours of operation) when it is operated and maintained as instructed. Regular maintenance and proper off-season storage help you reach that lifespan.

Typical lifespan for this model

The operator guidance for this snow thrower describes an average useful life of 7 years or 60 hours of operation, assuming proper maintenance. For many homeowners, that can cover multiple winter seasons depending on snowfall and how often you run the machine.

What you measure	Typical expectation	What it means in real use
Calendar time	7 years	Normal homeowner ownership timeframe
Run time	60 hours	Total engine-on time across seasons

What shortens snowblower life fastest

These are the most common causes we see for early wear on a 2-stage gas snowblower:

• Running with old fuel or storing fuel in the system over the off-season
• Skipping oil changes and seasonal lubrication
• Hitting hidden objects (curbs, gravel, ice chunks) that stress the auger and drivetrain
• Continuing to run after a belt starts slipping or a cable goes out of adjustment
• Not replacing normal wear items (belts, shear pins, skid shoes) as they wear down

Maintenance that helps you get the full 7 years

Follow the schedule and procedures in the owner's manual. These steps make the biggest difference:

• Change engine oil as recommended for the season
• Check and set spark plug gap during tune-ups
• Lubricate the hex shaft at least once per season (or about every 25 hours)
• Inspect belts and cables for glazing, cracking, stretching, or fraying
• Store it correctly at season end (run the engine until it stops to remove fuel from the tank, then prep the cylinder with a small amount of clean oil)

Parts that commonly wear out (and are normal to replace)

Wear items are expected over time. If performance drops, these are good first checks:

• Snowblower auger drive belt 256963 (auger stops under load, squealing, burning rubber smell)
• Shear pins (auger stops turning after hitting an object)
• Skid shoes (scraping, poor scraper bar contact, uneven clearing)

Why it matters

Knowing the expected lifespan helps you decide whether to tune up, replace a few wear parts, or plan for a larger repair. If your 247889700 is near 7 years old or approaching heavy run time, an annual inspection and proactive belt and cable checks can prevent mid-storm breakdowns.

Yes. For the Craftsman 247889700 26-inch snow thrower, 5W-30 is an approved engine oil type, and it is the best choice for cold-weather starting and winter operation. Fill to the dipstick range (do not overfill); the engine oil capacity is 20 oz. See the owner's manual for the exact checking and fill procedure.

What to use and when

For snowblower use, oil choice is mainly about temperature.

• 5W-30: Best for winter temperatures; easier starting and better cold-flow.
• SAE 30: Better for warm-weather operation; can be harder to start in cold.
• Use a 4-cycle engine oil with at least SF/SG classification (or higher).
• Check oil on a level surface with the engine off.
• Add oil slowly and stop when the level is between L and H on the dipstick.

Quick comparison

Oil type	Cold-weather starting	Typical snow season fit	Notes
5W-30	Best	Best	Listed as the engine oil type for this model
SAE 30	Fair to poor in cold	Limited	More common for warm temps; not ideal for freezing starts

How to avoid common oil problems

These issues cause hard starting, smoking, and plug fouling more often than the oil brand does.

• Do not overfill; too much oil can cause smoking and hard starting.
• If the machine was stored, change the oil before the season and after long storage.
• Keep the dipstick area clean so dirt does not fall into the crankcase.
• If the engine runs rough after an oil change, recheck the level and inspect the spark plug.

Why it matters

Snowblower engines run in cold, wet conditions. Using 5W-30 helps the engine lubricate quickly at startup, which reduces wear and improves reliability when you need the auger and drive system working in deep snow.

If you are also troubleshooting auger engagement or performance, worn belts can contribute; the snowblower auger drive belt 256963 is a common wear item on this model.

For your Craftsman 247889700 26" snow thrower, repairing is cheaper when the failure is a normal wear item (belts, shear pins, cables, skid shoes). Replacing makes more sense when a major assembly is damaged and the total repair cost is about half the price of a comparable new unit. Use the 247889700 owner's manual to confirm troubleshooting steps and maintenance before ordering parts.

Quick rule of thumb we use

• Repair when parts plus labor are under ~50% of replacement cost.
• Replace when repairs are over ~50%, or you have multiple major failures.
• Repair first when the machine is otherwise solid and the issue is a common wear point.

Repairs that are usually cost-effective

These are designed to wear or “sacrifice” to protect expensive components:

• Shear pins after hitting ice, gravel, or debris
• Slipping or worn auger belt
• Loss of drive from a worn ground drive belt
• Stretched or misadjusted clutch cables
• Worn skid shoes from pavement contact

A common model-matched wear part is the snowblower auger drive belt 256963 (part number 954-04050).

When replacement is often the better value

• Engine internal damage (short block, crankshaft, cylinder head)
• Auger gearbox damage after a hard jam
• Bent or cracked auger housing or frame

Cost comparison guide

Repair type	What it usually involves	Best value choice
Wear item	belts, shear pins, cables	Repair
One major assembly	gearbox, starter, housing	Compare costs
Multiple systems	engine plus drive plus auger	Replace

Why it matters

Snowblowers are built so inexpensive parts fail first; fixing those quickly helps prevent gearbox or engine damage and keeps performance consistent.

On the Craftsman 247889700 26" snow thrower, a bad auger belt shows up as weak or no snow throwing even though the engine runs and the auger control is engaged. Common signs include slipping, squealing, burning-rubber smell, or augers that stop under load; verify auger-control adjustment in the 247889700 owner's manual.

Quick symptoms to watch for

• Augers do not turn, or turn slowly, when you squeeze the auger control
• Augers start, then stop when they hit heavier snow
• Squealing noise right when the auger is engaged (belt slip)
• Rubber dust near the belt area, or a burnt-rubber odor
• Visible belt damage (cracks, glazing, fraying, missing chunks)

Rule out common look-alikes first

These issues can mimic a bad belt:

• Shear pins: If the augers hit a foreign object, shear pins can break and the augers will not drive.
• Auger control cable adjustment: The manual notes the cable should have very little slack when disengaged (not tight), and the augers should stop completely when you release the control.
• Ice jam: Packed snow or ice in the auger housing can stall the augers and make a good belt slip.

What to inspect (safe, basic check)

With the engine OFF and the ignition key removed:

• Check the belt for glazing (shiny, hardened surface), cracks, or frayed edges
• Look for oil contamination on the belt or pulleys
• Spin pulleys by hand; they should turn smoothly without wobble

Belt vs. shear pin: quick comparison

What happens	More likely cause	What you’ll notice
Auger control engaged, augers do not move at all	Shear pin(s) sheared	One or both augers freewheel on the shaft
Augers move but stop in heavy snow	Belt slipping or cable loose	Squeal, burning smell, inconsistent throwing

Why it matters

A slipping auger belt reduces throwing distance and overheats the belt and pulleys, which accelerates wear.

If you need a replacement, use the model-matched snowblower auger drive belt 256963 (part number 954-04050) from the parts list, or search by model on Sears PartsDirect.
