Craftsman 917257590 lawn tractor Parts

Yes, replacing the engine on your Craftsman lawn tractor model 917257590 is worth it when the tractor’s deck, steering, and drive system are still solid and you can keep the total cost well below the price of a comparable replacement tractor. Use the maintenance and safety guidance in the owner's manual to judge overall condition before investing.

• The mower deck is structurally sound (no major rust-through or cracks)
• The transmission and ground drive still pull strongly (no slipping, no loss of motion)
• Steering and front axle are tight enough to mow safely
• You can source the correct engine and mounting hardware for this frame
• You are already keeping up with annual maintenance (spark plug, air filter, belts, blades)
• The engine failure is truly internal (not a battery, solenoid, fuel, or safety switch issue)

A practical rule is to replace the engine when the engine swap cost (engine + any pulleys, belts, and labor) stays under about 50% of the cost of a similar used or new riding mower.

Many “bad engine” diagnoses are actually starting or fuel issues.

• Check battery cables and grounds for corrosion and tightness
• If it clicks, test the starter circuit and consider the solenoid 532146154
• Verify the safety interlock system is working (seat, brake, PTO)
• Replace seasonal maintenance items that affect starting and power (spark plug, air filter)
• Check for fuel flow restrictions (fuel filter is typically replaced once each season)

An engine swap only pays off when the rest of the tractor is dependable. The manual’s seasonal checks (belts, blades, air filter, brake operation, tire pressure, loose fasteners) help you avoid putting a new engine into a tractor that will immediately need major deck or drive repairs.
