Craftsman 917276640 tractor Parts

For a Craftsman front-engine lawn tractor like model 917276640, a complete engine replacement typically runs $600 to $2,500 installed (engine plus labor). The biggest cost driver is matching the correct engine configuration (horsepower, crankshaft size, mounting pattern) to your exact tractor setup; use the 917276640 owner's manual to confirm the engine family and specs before ordering.

Typical installed cost ranges

• Replacement engine: $400 to $2,000 (varies most by horsepower and crankshaft specs)
• Labor: $300 to $900 (commonly 4 to 8 hours for a riding mower)
• Fluids and small parts: $25 to $200 (oil, filter if equipped, fuel line clamps, hardware)
• Optional add-ons: $0 to $250 (battery, cables, belts, pulleys if worn)

Cost item	Typical range	What changes the price most
Engine	$400 to $2,000	HP, crankshaft diameter/length, PTO type
Labor	$300 to $900	Rusted fasteners, wiring transfers, test time
Fluids/supplies	$25 to $200	Oil type, filter, fuel filter, hardware
Total installed	$600 to $2,500	Combination of the above

How to make the quote accurate for model 917276640

Engine swaps fail most often when the crankshaft and mounting specs do not match. Before you buy an engine, confirm:

• Engine model and type listed for your tractor
• Crankshaft diameter and length (must match the pulley and blade drive setup)
• Crankshaft orientation (vertical-shaft is typical for lawn tractors)
• Electrical connectors and charging output (stator/regulator compatibility)
• Throttle/choke and exhaust routing (linkages and muffler clearance)

Check these first; they can mimic a “bad engine”

The troubleshooting chart for this tractor family prioritizes basic no-crank and loss-of-power checks:

• Battery charge and clean terminals
• Fuse and wiring connections
• Starter circuit components (solenoid, starter)
• Air filter and fuel quality (stale fuel causes hard-start and power loss)

If the engine clicks but will not crank, use riding lawn mower engine clicks but doesnt turn over video to narrow it down before pricing an engine.

Why it matters

An engine replacement is one of the highest-cost repairs on a riding mower. Verifying the exact engine specs for 917276640 and ruling out battery, solenoid, fuel, and airflow issues prevents buying the wrong engine or paying for an unnecessary swap.

Yes, it’s worth repairing the engine on your Craftsman 917276640 lawn tractor when the problem is a normal maintenance issue (fuel, spark, air, belts) or a small electrical failure, because the fix is usually far less than replacing the tractor. If the engine has major internal damage, replacement is the better value.

Quick way to decide (cost vs. condition)

Use this checklist before you spend money on parts or labor:

• The tractor is under 8 years old and the frame, deck, and transmission are in good shape.
• The issue is starting, running rough, or stalling, not a loud knock or seized engine.
• You can do basic DIY work (battery, spark plug, air filter, fuel cleanup).
• The repair estimate is under $100 to $300 for common fixes.
• You have not had repeated failures from stale/oxidized fuel (fuel should be used within about 30 days of purchase).

For model-specific maintenance intervals and operating guidance, follow the 917276640 owner's manual.

Common “worth it” repairs on this tractor

These are the repairs we see most often that restore reliable operation at a reasonable cost:

Symptom	Most common cause	Typical fix
Clicks but won’t crank	Weak battery, bad connections, solenoid	Clean/tighten cables; test/replace solenoid
Cranks but won’t start	Stale fuel, dirty carburetor, ignition issue	Drain old fuel; clean fuel system; tune-up
Runs but cuts poorly	Dull/bent blades, deck buildup, deck not level	Replace blades; clean deck; level deck
Blades won’t engage	Worn belt, frozen idler/mandrel	Inspect belt path; replace worn parts

If you’re chasing a no-crank issue, the lawn tractor starter solenoid 582042802 is a common electrical wear item.

When replacement makes more sense

Engine replacement (or replacing the tractor) is the better call when you have:

• A seized engine or no compression
• A thrown rod, cracked case, or heavy metal contamination in oil
• A bent crankshaft from impact
• Repair costs that approach a large share of a comparable replacement tractor

Why it matters

Putting money into the engine only pays off if the rest of the Craftsman 917276640 is solid. The manual also highlights that many “engine problems” start with preventable causes like improper storage and stale fuel, so correcting those habits protects your repair investment.

On the Craftsman riding tractor model 917276640, the engine system is made up of fuel, air, ignition, and starting components that work together to create spark and power, plus safety controls that let the tractor start and run correctly. For your exact layout, use the 917276640 owner's manual.

Main lawn tractor engine parts (what they do)

• Fuel tank and fuel line: stores and delivers gasoline to the engine
• Carburetor: mixes fuel and air for combustion
• Air filter: keeps dirt out of the engine intake
• Throttle/choke control: helps start a cold engine and controls engine speed
• Ignition system: spark plug and ignition coil create spark at the right time
• Starter system: battery, starter motor, and solenoid crank the engine
• Flywheel: helps the engine run smoothly and supports ignition timing

Related tractor controls you will see on this model

Your 917276640 also uses operator controls that directly affect starting and engine operation:

• Clutch/brake pedal (used for braking and starting)
• Parking brake (locks the brake position)
• Ignition switch (starts and stops the engine)
• Attachment clutch lever (engages mower blades)

Quick “engine system” breakdown

System	Common parts included	What you notice when it fails
Fuel	tank, line, carburetor	hard starting, surging, stalls
Air	air filter, intake	black smoke, loss of power
Ignition	spark plug, ignition coil, flywheel	no start, misfire
Starting/charging	battery, solenoid, wiring	clicks, slow crank, dead battery

Why it matters

Knowing which system you are troubleshooting helps you avoid replacing the wrong part. For example, a “click but no crank” points to the starting circuit (often the solenoid or battery connections), while “starts then dies” often points to fuel delivery or air restriction.

Craftsman lawn tractor model 917276640 is equipped with a low-emission gasoline engine; the exact engine make, displacement, and spec number are identified on the engine ID label. Use the label information and confirm operating specs in the 917276640 owner's manual.

How to identify the exact engine on model 917276640

Use the engine’s ID tag to get the correct engine details for tune-up parts and service.

• Find the engine ID label on the blower housing, valve cover, or near the starter
• Write down every field shown (commonly model, type, and code on Briggs & Stratton)
• Match that information to the engine maintenance section in the manual
• Use the engine ID when ordering spark plug, air filter, fuel filter, and oil filter
• If the label is missing, look for a stamped number on the shroud or valve cover

What the manual tells you (and what it does not)

The operator documentation for 917276640 confirms the tractor family and operating guidance, and it flags that the engine is a low-emission design. The engine’s manufacturer and exact model are verified from the engine label.

Detail	Where to get it	Why it matters
Tractor model number	Tractor frame tag	Ensures correct tractor parts and procedures
Engine make and model	Engine ID label	Ensures correct engine tune-up parts
Oil type and service intervals	Manual maintenance section	Prevents hard starting and premature wear

Why it matters

Engine identification is what keeps you from buying the wrong maintenance parts and chasing the wrong no-start or rough-run diagnosis. It also ensures you use the correct oil grade and service schedule for this low-emission engine.

Related deck parts if the issue is cutting quality (not the engine)

If the tractor runs fine but the cut is uneven or vibration is high, the mower deck is usually the cause.

• Check blades for bends and correct tightening
• Inspect spindle and mandrel play
• Verify belt routing and tension
• Look for grass buildup under the deck

A common deck spindle assembly used in the blade system is the lawn tractor mandrel housing 587819701.

A “Craftsman 6.75” walk-behind mower does not have one universal model number; “6.75” is an engine power label used across many different mowers. For the Craftsman riding tractor covered here, the model number is 917.276640 (also shown as 917276640) in the 917276640 owner's manual.

How to find the correct model number on your mower

Use the model number from the product ID tag, not the engine label.

• Look for a sticker or metal tag on the mower deck, rear housing, or under the seat (riding units)
• Write down the full model number exactly as shown (numbers and dots)
• Record the serial number too; it helps match parts and manuals
• If the tag is dirty or faded, clean it gently and use a flashlight to read it
• Use the model number to match blades, belts, and other parts correctly

“6.75” vs model number: what it means

“6.75” typically refers to the engine rating, while the model number identifies the mower itself.

Label you see	What it identifies	Used for parts lookup?
6.75 (engine label)	Engine power family	No
917.XXXXXX	Craftsman mower/tractor model	Yes
Engine model/type code	Engine manufacturer model	Sometimes (engine parts)

If you are actually asking about this Craftsman tractor model

If you are servicing Craftsman model 917276640, use the manual for operating and maintenance specs, and use the model number for parts matching. Common wear items include deck blades, belts, and pulleys.

• For blade-drive or ground-drive belt issues, inspect belt routing and idlers
• For deck vibration or uneven cut, check mandrel bearings and pulleys
• For starting problems, check battery connections and the starter circuit

Helpful DIY resource

For no-crank symptoms (clicking but not turning over), follow riding lawn mower engine clicks but doesnt turn over video.

Why it matters

Using the correct model number prevents ordering the wrong blade, belt length, or deck parts, which saves time and avoids fitment problems.

On the Craftsman riding lawn tractor model 917276640, a no-start is usually caused by a weak battery or bad cable connection, a safety interlock not being satisfied (brake, seat, PTO), or a fuel/ignition issue such as stale gas, a dirty air filter, or a fouled spark plug. Use the 917276640 owner's manual troubleshooting chart to narrow it down fast.

Quick checks we recommend (in order)

• Set parking brake fully; sit in the seat.
• Make sure the PTO/attachment clutch is disengaged (blades off).
• Check battery terminals for tight, clean connections.
• Try starting with the throttle in the recommended start position (per the manual).
• Confirm fresh fuel; old fuel is a common cause after storage.
• Inspect the air filter; replace if dirty or oil-soaked.
• Check the spark plug condition and gap; replace if fouled.

What the symptom tells you

What you hear/see	Most likely cause	What to do next
Single click, no crank	Weak battery, poor cables, bad solenoid	Clean/tighten cables; test battery; consider lawn tractor starter solenoid 582042802
Cranks normally, will not start	Fuel delivery or ignition problem	Fresh fuel, air filter, spark plug, carburetor cleaning
Starts then dies when you release brake	Safety interlock issue	Check brake switch, seat switch, wiring connections
No crank, no click	Blown fuse, bad key switch, open safety circuit	Inspect fuse, ignition switch, interlock wiring

Why it matters

On riding mowers like the 917276640, the operator-presence and PTO safety circuits are designed to prevent starting unless conditions are safe. That means a simple mis-set control or a failing switch can look like a “dead” engine even when the battery and starter are fine.

Helpful DIY guidance

If the engine clicks but will not turn over, follow riding lawn mower engine clicks but doesnt turn over video for a step-by-step diagnosis path.
