Craftsman 917276843 tractor Parts

Replacing the engine on a Craftsman riding lawn tractor model 917276843 typically costs $1,200 to $3,500 total (engine plus labor). The wide range comes from engine type/HP, whether you choose a new or used engine, and the amount of wiring, fuel-system, and belt work needed.

Key cost drivers we see on front-engine lawn tractors like the 917276843 include:

• Engine price (new vs. used vs. rebuilt)
• Labor hours (swap time plus setup and testing)
• Extra parts needed during the swap (belts, pulleys, wiring, clamps)
• Fuel system condition (stale fuel can mean extra cleaning)
• Deck and drive setup (PTO engagement, belt routing, and alignment)

For model-specific operating and maintenance details that affect engine life and service intervals, use the 917276843 operator’s manual.

These are common ranges for riding mower engine replacement jobs.

We recommend ruling out cheaper fixes first, because many “bad engine” symptoms are caused by ignition, fuel delivery, or safety interlocks.

• Verify fresh fuel and a clean fuel path (tank, line, filter)
• Check spark and basic tune-up items
• Confirm the PTO and safety interlock circuits are working correctly
• Inspect belts and pulleys for binding that can overload the engine
• Look for oil leaks or exhaust issues that may be repairable

If you are troubleshooting power loss when the blades are engaged, the guide why your mower loses power when the blades are engaged can help you narrow it down.

An engine swap is one of the highest-cost repairs on a riding mower. Getting an accurate estimate up front helps you decide whether to repair, repower, or put that money toward a replacement tractor.

Replacing the engine on your Craftsman lawn tractor model 917276843 is worth it when the tractor is otherwise in good shape and the total engine-swap cost stays well below the cost of a comparable replacement tractor. If the deck or transmission also needs major work, replacement usually makes more sense.

The operator information for this tractor family describes a 24.0 HP lawn tractor with a 48-inch mower deck and automatic transmission. Use the 917276843 operator’s manual to verify specs and review maintenance and troubleshooting before committing to an engine swap.

• Confirm the transmission drives smoothly with no slipping or loss of motion
• Inspect the mower deck for rust-through, cracks, or damaged mounting points
• Check steering and front axle for excessive play
• Verify the charging and starting system is reliable
• Make sure a replacement engine can match crankshaft size, mounting pattern, and wiring

Many no-start or low-power complaints are caused by maintenance or electrical issues, not a failed engine:

• Stale fuel or restricted fuel flow
• Dirty air filter or clogged cooling fins (overheating)
• Worn spark plug or ignition issue
• Safety interlock switch problem
• Weak battery or poor cable connections

If you hear a click but the engine will not crank, the starting circuit is a common place to begin; a failed solenoid is one possible cause (see lawn tractor starter solenoid 582042802).

An engine swap is one of the highest-cost repairs on a riding mower. Checking the deck, transmission, and electrical system first helps prevent spending engine money on a tractor with other expensive problems.

On the Craftsman lawn tractor model 917276843, the engine is made up of fuel, air, ignition, and mechanical systems that work together to create power. You will typically see components like the fuel tank, air filter, carburetor, spark plug, and flywheel, plus internal parts such as the crankshaft and piston.

• Fuel system: stores and delivers gasoline to the engine (tank, fuel line, filter, carburetor)
• Air intake: cleans and meters air for combustion (air filter, intake path)
• Ignition: creates spark at the right time (ignition coil, spark plug)
• Lubrication: reduces wear and heat (oil, oil fill/dipstick, drain points)
• Mechanical rotating assembly: converts combustion into rotation (piston, connecting rod, crankshaft)

For model-specific operating and maintenance details (oil type, spark plug spec, service intervals), use the 917276843 owner’s manual.

Even though internal engine parts vary by engine manufacturer, these external items are the most commonly inspected or replaced:

• Fuel tank and cap
• Fuel line and clamps
• Air filter (paper cartridge and/or pre-cleaner)
• Spark plug
• Muffler and heat shields
• Starter/solenoid and wiring

If you’re chasing a fuel smell, leak, or fuel delivery issue, a good starting point is the husqvarna lawn tractor fuel tank 532193499 and the lawn tractor fuel line 587044864 (both are model-compatible parts listed for 917276843).

Knowing which system a part belongs to helps you troubleshoot faster. For example, “starts then dies” often points to fuel delivery or air intake, while “cranks but won’t fire” often points to ignition.

For Craftsman lawn tractor model 917276843, the operator’s manual for this model series specifies a 24.0 HP gasoline-powered tractor with electric start; it does not identify the engine’s manufacturer or exact engine model family in the excerpted model-specific information. Use the engine ID label on your tractor to confirm the exact engine make and model; see the 917276843 operator's manual.

With the engine off and cooled:

• Find the engine ID label (often on the blower housing, valve cover, or near the starter)
• Write down the engine model, type, and code/spec numbers exactly
• Match those numbers to the engine maintenance information in the 917276843 operator's manual
• If the label is missing, look for a stamped tag or plate on the engine shroud
• Use 917276843 when browsing diagrams so you only see compatible tractor parts

The manual text covering the 917.276843 series lists these tractor-level specifications:

The engine make and model determine the correct tune-up parts (spark plug, air filter, fuel filter) and service steps. Confirming the engine ID prevents ordering the wrong maintenance parts even when the tractor model number is correct.
