Craftsman 917251480 tractor Parts

The Craftsman tractor model 917251480 does not map to a single model year; the exact build date is tied to the serial number on the ID plate under the seat. Use the serial number and the date-of-purchase fields shown in the owner's manual to identify when your specific tractor was made.

• Park on a level surface, set the parking brake, and remove the key.
• Lift the seat and locate the model/serial plate under the seat.
• Confirm the model reads 917.251480 (often shown with a dot in the manual).
• Write down the serial number exactly as shown.
• Compare the serial number format to the identification guidance in the manual.
• If the plate is missing or unreadable, check for a duplicate label on the frame near the seat pan.

The documentation for this Craftsman front-engine lawn tractor states the model and serial numbers are found on a plate under the seat, and it instructs you to record the serial number and date of purchase for future reference.

Parts, wiring, and deck configurations can vary within the same Craftsman 917-series tractor family. Using the serial number helps us match the correct diagrams and replacement parts (for example, electrical items like a solenoid 532146154 or a molded ignition key 532140403).

For the Craftsman riding tractor model 917251480, the engine is identified in the documentation as engine model MV18S-58560; that engine model is the best way to determine the actual engine manufacturer and to match the correct tune-up and repair parts. Use the owner's manual to confirm the engine model number on your tractor before ordering.

Use the engine model number, not just the Craftsman tractor model number.

• Lift the seat and locate the tractor model plate (tractor model 917251480).
• Find the engine model number on the blower housing (the manual notes this location).
• Match that engine model number to the correct engine parts list and specifications.
• If your tractor has been serviced before, verify the engine tag is still readable and original.
• Use the engine model number when searching for ignition, fuel, and starting components.

The documentation for model 917251480 lists a specific engine model number, which is the key identifier for the engine maker.

Craftsman tractors can be sold with engines from different manufacturers across model years and configurations. The engine model number ensures you get the right parts and procedures for starting, charging, fuel delivery, and tune-ups.

If the engine will not crank or you only hear a click, these parts are often involved:

• Starter solenoid (switches battery power to the starter): solenoid 532146154
• Ignition key (worn key can cause intermittent no-start): molded ignition key 532140403
• PTO switch (can prevent cranking if the safety circuit is not satisfied): switch 582107601

For Craftsman model 917251480, the engine is a gasoline-powered internal combustion engine; the specifications in the owner's manual list 18.5 horsepower and standard small-engine service items such as spark plug and oil type.

From the model’s specifications, these are the key engine-related details:

• Horsepower: 18.5 HP
• Fuel: unleaded regular gasoline
• Oil type: SAE 30 (above 32°F) or SAE 5W-30 (below 32°F)
• Oil capacity: 4.0 pints with filter, 3.5 pints without filter
• Spark plug: Champion RV17YC, gap 0.025 in.

Using the correct oil viscosity, oil fill amount, and spark plug spec helps your Craftsman tractor start easier, run cooler, and reduce premature engine wear, especially during seasonal temperature changes.

If you are doing basic upkeep, these checks help prevent common no-start and rough-running issues:

• Verify the ignition key is in good shape and fully engaging the switch (see molded ignition key 532140403)
• Keep battery connections clean and tight (a weak connection can mimic a bad starter)
• If you hear a click but the starter will not crank, inspect the starter circuit and solenoid (see solenoid 532146154)
• Follow the maintenance schedule intervals listed in the manual for oil changes and spark plug service

Yes, replacing the engine on your Craftsman 917251480 lawn tractor is worth it when the tractor’s deck, steering, and drive system are still solid and the total engine-swap cost stays well below the cost of replacing the whole machine. It is not worth it when multiple major systems are worn out.

• Deck condition: no severe rust-through, cracks, or repeated spindle/mandrel failures
• Drive system: transmission and ground drive work consistently (no slipping, no loss of power)
• Electrical system: starting and safety circuits are repairable (switches, wiring, solenoid)
• Parts availability: common wear parts are still easy to get for 917251480
• Total cost: engine + required swap parts + your time is under ~50% of a comparable replacement tractor

Engine swaps vary, but these are the typical “hidden” items that decide value.

Your owner's manual troubleshooting guidance points to several frequent causes of no-start, loss of power, and rough running that are cheaper than an engine replacement.

• Check for dirty air filter and bad spark plug (common loss-of-power and no-start causes)
• Verify battery condition and clean/tighten terminals (weak battery is a top no-crank cause)
• Inspect for loose/damaged wiring and blown fuse
• If it clicks but will not crank, test the starter solenoid and related connections
• Drain stale fuel and replace the fuel filter if the tractor sat with old gasoline

If you’re chasing a no-crank issue, the solenoid 532146154 is a common fix when the battery is good but the starter circuit will not engage.

An engine is only one part of the total machine. If the deck, belts, pulleys, wiring, and safety interlocks are already near end-of-life, a new engine can still leave you with an unreliable tractor. If the rest of the tractor is sound, an engine swap can restore years of service.

On the Craftsman 917251480 front-engine lawn tractor, the engine is made up of fuel, air, ignition, and internal mechanical systems that work together to create power. Your owner's manual also shows engine-specific assemblies such as the flywheel, governor, breather and vent, and carburetor components.

• Fuel system: stores and delivers gasoline to the engine (tank, fuel line, fuel pump, carburetor)
• Air intake and filtration: cleans and meters air for combustion (air filter, intake manifold)
• Ignition system: creates spark at the right time (ignition switch, ignition module/coil, spark plug)
• Engine mechanicals: convert combustion into rotation (crankcase, crankshaft, connecting rod, valves)
• Governor and throttle linkage: controls engine speed under load (governor gear/linkage, throttle lever)
• Breather and vent: manages crankcase pressure and oil vapor (breather hose, umbrella valve)

The 917251480 uses a KOHLER engine (manual parts list shows MV18S, type 58560). Here are examples of engine assemblies called out in the manual and what they include.

• Cranks but will not start: fuel delivery, carburetor, ignition spark, choke setting
• Clicks but will not crank: battery cables, starter circuit, starter solenoid
• Surges or hunts at steady throttle: governor linkage, carburetor mixture, air leak
• Smokes or pushes oil mist: breather and vent components, oil level, worn internal parts

Knowing the engine systems helps you troubleshoot faster and order the right replacement parts the first time. For example, a no-crank problem often points to the starting circuit, where a failed solenoid 532146154 is a common fix on riding tractors.
