Craftsman 917258671 lawn tractor Parts

A “Craftsman 6.75” label by itself is not a single model number; it describes the engine power class used across many walk-behind mowers. For your Craftsman riding lawn tractor on this page, the correct model number is 917258671, shown on the tractor’s model plate under the seat (see the 917258671 owner's manual).

How to find the model number on a Craftsman mower

Use these quick checks to get the exact model number you need for parts and manuals:

• Riding lawn tractor (like model 917258671): look under the seat on the model plate
• Walk-behind mower (often labeled 6.75): check the rear deck, side of the deck, or near the bagger mount for a sticker/plate
• Write down the full model number exactly as shown (numbers and punctuation)
• If you also need engine parts, record the engine model number from the blower housing
• Match parts by model number first, then confirm by part description

Why “6.75” is not the model number

“6.75” is commonly used as an engine rating/series identifier, so multiple Craftsman walk-behind mowers can share that marking while having different model numbers.

What to use instead

You have	Use this to look up parts	Where to find it
Craftsman riding tractor	Tractor model number (example: 917258671)	Under the seat
Craftsman walk-behind mower labeled 6.75	Mower model number (varies by unit)	On the mower deck
Engine parts request	Engine model/type code	On engine blower housing

Why it matters

The model number controls the exact fit for key items like belts, pulleys, steering parts, and deck hardware. For example, the correct ground drive belt length and width must match the tractor’s routing and pulley setup; for this model, a common replacement is the lawn tractor ground drive belt, 1/2 x 82-in 532140294.

For a Craftsman riding lawn tractor like model 917258671, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine price, any extra parts needed (belts, pulleys, wiring), and local labor rates; plan on about 6 hours of labor for many riding mower engine swaps.

What drives the total cost

• Engine cost (biggest variable): new, rebuilt, or used
• Labor time: engine removal, transfer of parts, alignment, test run
• Extra parts often replaced “while you’re in there”
  • Drive belt (if worn): lawn tractor ground drive belt, 1/2 x 82-in 532140294
  • Starter electrical parts (if starting issues exist): solenoid 532146154
• Shop supplies: oil, filter, fuel line clamps, hardware
• Diagnosis first: sometimes a no-start is electrical or fuel-related, not a failed engine

Before you replace the engine: quick checks that save money

Many “dead engine” complaints are caused by starting or safety circuit issues. Use the troubleshooting and service sections in the owner's manual to confirm the failure before buying an engine.

• Verify the battery and cable connections are clean and tight
• Check the fuse and wiring connections
• Confirm the freewheel control is not in the disengaged position
• Make sure the PTO/blade switch is off and brake is fully applied
• If you hear clicking, focus on the starting circuit (battery, cables, solenoid)

Typical cost ranges (what most customers see)

Scenario	What you pay for	Typical total cost
Budget repair	Used/rebuilt engine + minimal extras	$260 to $800
Most common	New engine + standard labor	$800 to $1,400
Highest cost	New engine + multiple related parts + higher labor rates	$1,400 to $1,800

Why it matters

An engine swap is one of the highest-cost repairs on a lawn tractor. Confirming whether the issue is the engine itself versus the starting system, drive system, or safety interlocks helps you avoid replacing a good engine and gets your Craftsman 917258671 back to reliable operation faster.

If you decide to move forward, we recommend pricing the repair parts you may need alongside the engine and ordering everything together through the parts list for your model, or searching by model number on Sears PartsDirect.

Yes, replacing the engine on your Craftsman lawn tractor model 917258671 is worth it when the tractor’s deck, transmission, and steering are in solid condition and the total engine-swap cost stays well below the cost of replacing the whole tractor. If multiple major systems are worn out, replacement makes more sense.

Quick decision checklist

• The mower deck is structurally sound (no major rust-through or cracks)
• The tractor still drives normally (no slipping or loss of drive)
• Steering and front axle feel tight (no severe play or binding)
• You can complete basic maintenance safely (spark plug wire disconnected before work)
• The engine failure is isolated (not paired with repeated belt, pulley, or mandrel problems)

Cost and effort: what to compare

Use this simple comparison to decide where your money goes.

Option	What you pay for	Best when	Watch-outs
Replace engine	Engine plus install time	Tractor is otherwise in good shape	Hidden wear in belts, pulleys, wiring
Repair existing engine	Parts and diagnostics	Problem is minor (fuel, ignition, compression issue)	Can turn into repeated repairs
Replace tractor	New unit	Deck, drive, and steering all show heavy wear	Higher upfront cost

What to inspect on model 917258671 before committing

These checks help you avoid putting a new engine on a tractor that still will not perform.

• Drive system: If you have loss of drive, a worn belt is a common cause; the lawn tractor ground drive belt, 1/2 x 82-in 532140294 is a typical wear item.
• Starting circuit: If you only get a click or intermittent crank, the solenoid 532146154 is a common failure point.
• Deck hardware: Uneven cut and vibration often trace back to deck issues; worn mandrels and idlers matter (the manual calls out belt routing and checking idlers/mandrels for free rotation).
• Safety and serviceability: Our manual emphasizes disconnecting the spark plug wire before repairs and never adjusting or repairing with the engine running.

Why it matters

An engine swap can restore reliability, but it only pays off if the tractor’s core systems (deck, drive, steering, and electrical) are healthy. Otherwise, you can end up chasing multiple problems after the engine is replaced.

For model-specific maintenance and deck/drive belt procedures, use the owner's manual. For broader parts lookup by model number, use Sears PartsDirect.

On a Craftsman lawn tractor like model 917258671, the model number does not contain the build year. To identify the year, we use the product serial number from the tractor’s ID tag; the year is encoded in the serial format used on that tag. For exact ID-tag locations and labeling, use the 917258671 owner's manual.

Where to find the serial number (ID tag)

We use the serial number printed on the tractor’s identification tag, not the engine label.

• Look under the seat pan area and around the rear fender/seat bracket
• Check the frame rail near the engine compartment
• Look near the rear axle or hitch plate area
• Wipe dirt and grass off the tag so every digit is readable
• Write the serial number exactly as shown (include letters, if present)

How serial number date codes are commonly read

Many Craftsman riding mower serial formats use a date-coded sequence (often month, day, year) within the serial number. When your serial number follows that pattern, the last two digits in the date block indicate the year.

Quick example (date-coded format)

Date block in serial	Interprets as	Year
072811	July 28, 2011	2011
041905	April 19, 2005	2005

Why it matters

The build year helps us match the correct parts and diagrams for your 917258671, especially for wear items like belts, steering parts, and deck hardware. For example, if you are ordering a drive belt, we match by model and configuration, such as the lawn tractor ground drive belt, 1/2 x 82-in 532140294.

Tips to avoid mix-ups when ordering parts

• Use the full model number: 917258671
• Use the serial number from the tractor ID tag (not the engine)
• Match parts by description and diagram callout in the manual
• Replace related fasteners when needed (example: hex flange lock nut 532409149)

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

Craftsman lawn tractor model 917258671 uses a gasoline engine; the exact engine manufacturer, model, and horsepower are identified on the engine ID label mounted on the engine itself. We use that label information to match the correct tune-up, fuel, and starting parts.

How to identify the engine on model 917258671

Look for an engine ID tag or sticker in these common spots:

• On the blower housing or engine shroud
• Near the spark plug or valve cover
• Near the muffler heat shield area
• Under the hood on the engine or frame rail close to the engine

For diagrams and control locations while you check, use the 917258671 owner's manual.

What to write down from the engine label

Record the numbers exactly as shown; most small engines list:

• Engine model number
• Type/trim or spec number
• Code or date number
• Any serial number shown

Engine label fields and what they do

Label field	What it helps us match
Model number	Correct engine family parts (filters, plugs, carb kits)
Type/trim (spec)	Correct carburetor and ignition variations
Code/date	Correct revision changes across production runs

Why it matters

The tractor model number 917258671 identifies the chassis, deck, and drive system, but many maintenance and repair parts are engine-specific. Using the engine ID label prevents ordering the wrong air filter, spark plug, starter parts, or carburetor components.

Related parts that are often confused with “engine problems”

If the tractor runs but does not move well, the issue is often in the drive system:

• Worn or stretched drive belt
• Idler pulley or spring problems
• Transmission freewheel control left disengaged

A common wear item on this model is the lawn tractor ground drive belt, 1/2 x 82-in 532140294.

If you need additional parts beyond what is listed for model 917258671, you can also search by model number on Sears PartsDirect.
