Craftsman 247887890 snow thrower Parts

On the Craftsman snow thrower model 247887890, the serial number is printed on the product identification label (ID tag) on the machine. Use the serial number exactly as shown on that label when ordering parts or checking specifications in the 247887890 operator’s manual.

Where to find the ID label

Most Craftsman snow throwers place the model and serial label on the rear or lower frame area near the wheels. Check these common spots:

• Backside of the metal base between the left and right rear wheels
• Rear frame panel behind the engine
• Lower handle support area near the axle
• Side of the auger housing frame (near the rear)

How to read the serial number correctly

Once you find the label, copy the serial number exactly. We recommend:

• Write it down or take a clear photo
• Include all letters and numbers (do not skip leading zeros)
• Keep dashes and spaces only if they appear on the label
• Record the date of purchase with it for maintenance tracking

Model number vs. serial number (quick comparison)

Item	What it tells you	How it’s used
Model number	The exact snowblower design family	Matching diagrams and correct replacement parts
Serial number	The unique build identifier for your unit	Confirming production details and version changes

Why it matters

The model number gets you to the right parts breakdown; the serial number helps confirm you are buying the correct revision of a part when a snowblower has running changes during production.

For a Craftsman snow thrower model 247887890, the most reliable way to estimate the year is to use the engine identification code (often called the engine model, type, and code). The code includes a manufacture date for the engine, which is usually very close to the snowblower’s build year. See the 247887890 operator’s manual for label locations and model identification basics.

Where to find the date information

Most snowblowers do not have a simple “model year” printed like a car. Instead, you date the unit by dating the engine and confirming the product labels.

Check these common locations:

• Engine shroud/blower housing: sticker or stamped plate with engine numbers
• Valve cover area (some engines): tag or stamping
• Frame tag on the snowblower: model and serial label (often near the rear frame or under the handle area)
• Under the belt cover area: sometimes a secondary label is present

How to read common small-engine date codes

Many small engines use a numeric code where the first two digits indicate the year and the next two digits indicate the month (format varies by engine maker).

A common example format:

Example code	Interpreted as	What it tells you
99011556	1999-01-15	Engine built Jan 15, 1999
170623XX	2017-06-23	Engine built Jun 23, 2017

Use the engine’s code format for your specific engine brand (Briggs and Stratton, Tecumseh, etc.). Once you have the engine build date, the snowblower is typically from the same year or the year immediately after.

Quick cross-checks that confirm the year

Use these clues to make sure the engine date matches the machine:

• The snowblower model/serial tag looks original and unaltered
• The engine appears to be the original engine (matching mounting, controls, and wiring)
• The operator’s manual printing date can provide a time window (for example, many manuals show a form number and date)

Why it matters

Knowing the approximate year helps us match the correct Craftsman parts (belts, cables, skid shoes, shear pins) and ensures you get the right maintenance specs for fuel, oil type, and adjustments.

A gas snowblower typically lasts 10 to 20 years with normal homeowner use and consistent maintenance. For Craftsman model 247887890, the operator’s manual also lists an Average Useful Life of 7 years or 60 hours; many machines run longer when they are serviced and stored correctly (especially the fuel system).

What “useful life” means for this model

The manual’s “Average Useful Life” is a service and safety benchmark, not a hard stop date. At that point, the manual calls for annual inspection so worn mechanical and safety systems do not create hazards. See the 247887890 owner’s manual.

What makes a snowblower last longer (or fail early)

We see lifespan swing widely based on maintenance, storage, and how hard the machine works.

• Change engine oil on schedule; dirty oil accelerates engine wear.
• Drain or run out fuel before storage; old fuel gums up the carburetor.
• Clear snow from the housing before storing to reduce freeze-up and corrosion.
• Lubricate key moving parts at least once per season (the manual notes the hex shaft at least once a season or every 25 hours).
• Replace wear items before they damage other parts (belts, skid shoes, scraper blade, shear pins).
• Avoid overloading the auger in heavy, wet snow; let the machine work at its pace.

Quick lifespan guide (typical)

Snowblower type	Typical lifespan	Notes
Gas, homeowner use	10 to 20 years	Most common range with routine maintenance
Gas, heavy use	7 to 15 years	More wear on friction wheel, belts, cables
Electric (corded/battery)	5 to 10 years	Often limited by motor/battery life

Why it matters

Planning around lifespan helps you decide when to invest in maintenance versus major repairs. For example, replacing a worn scraper blade or skid shoes can protect the auger housing and improve clearing performance, while proper off-season storage prevents fuel-system problems that cause hard starting.

The most common snowblower problem is a no-start or hard-start condition, usually caused by fuel issues (old gas, varnished carburetor) or ignition maintenance (spark plug). On the Craftsman snow thrower model 247887890, the next most common issues are chute clogs and the auger not turning due to sheared shear pins.

Quick checks we recommend first

• Confirm fresh, clean unleaded fuel is in the tank (old fuel is the top cause of starting trouble).
• Check the spark plug condition and connection.
• If the unit runs but will not throw snow, inspect for a clogged discharge chute.
• If one auger does not turn, inspect the shear pin and clip on that auger.
• If the auger engages weakly, check auger cable adjustment and belt condition.

If it will not discharge snow (runs, but no throwing)

Your 247887890 manual troubleshooting points to these common causes: chute clogged, foreign object in auger, auger cable needs adjustment, auger belt loose/damaged, or shear pins sheared. Use the safe clearing steps in the 247887890 owner's manual.

Symptom	Most likely cause	Typical fix
Snow backs up in chute	Chute clogged	Shut engine off, wait for impeller to stop, clear with clean-out tool
Auger not turning	Shear pin sheared	Replace shear pin and clip
Weak auger engagement	Cable out of adjustment or belt worn	Adjust cable; replace belt if damaged

Shear pins: the most common “auger won’t turn” fix

If an auger blade strikes ice or a foreign object, the shear pin is designed to break to protect the gearbox. For this model, the manual calls out OEM shear pin part number 738-04124A for 2-stage units; replacing with the correct part prevents expensive damage. If you need replacements, use Craftsman snowblower shear pin 738-04124A.

Why it matters

Starting issues and chute or auger problems are common because snowblowers sit unused for long periods, then get pushed hard in wet snow and ice. A few quick checks and the right OEM shear pins prevent downtime and protect the auger gearbox.
