Craftsman 917270612 tractor Parts

For a Craftsman riding lawn tractor like model 917270612, a full engine replacement typically runs about $800 to $2,500 total (engine, labor, and incidentals). Costs vary most by engine type, whether the replacement is a direct-fit, and how much teardown is required; see the 917270612 owner's manual for model-specific service guidance and safety steps.

• Engine price: direct-fit engines cost less than upgraded or hard-to-source engines.
• Labor time: riding mower engine swaps commonly take 4 to 8 hours.
• Extra parts: fuel line, clamps, filters, spark plug, and belts are often replaced at the same time.
• Shop rates: local labor rates and pickup/delivery can add significantly.
• Condition issues: stripped mounting bolts, damaged wiring, or worn pulleys increase time.

We recommend ruling out common “no-start” causes first, because they can look like a bad engine:

• Weak battery or poor cable connections
• Safety interlock switch issue (seat, brake, PTO)
• Fuel delivery problem (old gas, clogged fuel filter)
• Ignition issue (spark plug, wiring)
• Starter/solenoid problem (clicks but won’t crank)

A quick DIY check can save a full engine swap; the riding lawn mower engine spins but wont start video is a good starting point.

An engine replacement can cost close to the value of an older riding mower. Confirming the real failure (compression loss, thrown rod, seized crankshaft) helps you decide whether to repair, replace the tractor, or address a simpler starting or fuel issue.

For Craftsman model 917270612, the owner’s manual identifies it as a 15.5 HP, electric-start lawn tractor. This model uses a Briggs & Stratton engine family (the manual references an “engine B&S” harness), and it’s designed to run at full throttle for best mowing and battery charging performance. See the 917270612 owner's manual for the exact engine identification details.

The fastest way is to match the engine’s model/type/code to what’s on your tractor.

• Look for the engine ID label on the blower housing, valve cover area, or near the starter
• Record Model, Type, and Code from the Briggs & Stratton tag
• Compare that information to the engine section in the 917270612 owner's manual
• If the label is dirty, wipe it and use a flashlight; numbers are often lightly stamped
• Use the tractor model number 917270612 when ordering engine-related parts

Based on the manual specs for this tractor, you can expect these engine-related requirements:

The exact Briggs & Stratton engine model determines the correct tune-up parts (spark plug, air filter, fuel filter), oil recommendations, and any engine-specific service procedures. Using the engine ID from the tractor prevents ordering the wrong parts.

Craftsman model 917270612 is identified by model and serial labels; the exact build year is determined from the tractor serial number and the engine date code, not from the model number alone. Use the ID labels on the tractor and the 917270612 owner's manual to match the correct identification locations.

Use the tractor and engine identification tags together; that combination dates the unit accurately.

• Find the tractor model and serial label (commonly under the seat, on the frame rail, or near the rear fender)
• Write down the serial number exactly (include any letters)
• Locate the engine identification label on the engine shroud or valve cover area
• Record the engine model, type, and code (the code is the date identifier)
• Use the engine code to determine the engine manufacture date; the tractor build date typically falls in the same timeframe

The manual confirms the tractor model number and provides parts breakdowns for major assemblies; those diagrams help you verify configuration when you are narrowing down the correct production timeframe.

Craftsman tractors often have running changes within the same model number. Confirming the build timeframe helps you choose the correct belts, steering parts, and deck components, such as the lawn tractor drive belt 532144200 when applicable.
