Craftsman 917255933 lawn tractor Parts

Replacing the engine on a Craftsman riding lawn tractor like model 917255933 typically costs $260 to $1,800 installed, depending on the engine type, whether you reuse pulleys and wiring, and local labor rates. Engine swaps on riding mowers usually take about 6 hours of labor.

• Engine price: the biggest variable (new, rebuilt, or used)
• Labor time: riding mower engine swaps commonly run longer than walk-behind mowers
• Extra parts: belts, hardware, fuel parts, and electrical parts often get replaced at the same time
• Shop supplies: oil, filter, fuel line, clamps, and sealants
• Condition issues: rusted fasteners, damaged wiring, or worn pulleys add time

If your tractor had starting or electrical issues before the engine failed, these parts are common add-ons:

• Solenoid 532146154 (starter solenoid)
• Lawn tractor ignition switch 532365402 (key switch)
• Lawn tractor seat switch 532421062 (safety interlock)
• Lawn tractor ground drive belt 532110883 (drive belt)

An engine replacement only makes sense when the rest of the tractor (deck, transmission, steering, and wiring) is in solid shape. Pricing the job as “engine + labor + the few parts that caused the original no-start” helps prevent paying twice for the same teardown.

• Confirm the crankshaft diameter/length and mounting pattern on the old engine
• Inspect belts and pulleys for glazing, cracking, or wobble
• Check safety interlocks (seat and PTO) if the tractor had intermittent starting
• Price the parts list for your model first, then compare to searching by model on Sears PartsDirect

Craftsman lawn tractor model 917255933 uses a Briggs & Stratton single-cylinder gasoline engine. To confirm the exact engine model and type on your tractor (so tune-up parts match), read the engine ID label on the blower housing or valve cover.

We use the engine’s ID tag because the tractor model number identifies the chassis, while the engine tag identifies the correct engine parts.

• Lift the hood and locate the engine ID label
• Check the blower housing (shroud) and valve cover area
• Record the numbers exactly: model, type, and code
• Use those numbers when selecting spark plug, air filter, and fuel system parts
• If the label is dirty, wipe it clean and take a photo for accuracy

If you are troubleshooting a no-crank or intermittent start, these model-listed parts are often involved in the starting and safety interlock circuits:

• Solenoid 532146154
• Lawn tractor ignition switch 532365402
• Lawn tractor seat switch 532421062

The engine model and type determine the correct maintenance parts and some electrical components. Matching the engine ID prevents ordering the wrong ignition or fuel parts even when the tractor model number is correct.

On a Craftsman lawn tractor like model 917255933, the model number does not contain the build year; you typically determine the year from the product serial number on the ID tag. Many Craftsman-built units use a date-coded serial format where the last two digits indicate the year.

Look for a product ID label in one of these common locations:

• Under the seat pan (lift the seat)
• On the rear fender pan near the seat
• On the frame rail near the engine
• Near the transaxle area on the frame

Write down the full serial number exactly as shown, including any letters.

Craftsman riding mowers commonly use a 6-digit date code within the serial number that reads:

• First 2 digits: month (01 to 12)
• Next 2 digits: day (01 to 31)
• Last 2 digits: year (00 to 99)

If the serial number begins with 072811, that decodes to:

That would indicate a build date of July 28, 2011.

If your serial number is longer, includes letters, or does not start with a clear MMDDYY pattern, use these practical checks to narrow it down:

• Compare the engine model and spec numbers to the tractor ID tag (they often align to a production era)
• Check whether your tractor uses a key ignition or a PTO switch style typical of certain years
• Match wear parts to the correct diagrams for model 917255933 to confirm you are in the right parts family

If you are troubleshooting a no-crank or click condition while you are identifying the tractor, our DIY video guide can help: riding lawn mower engine clicks but doesnt turn over video.

Knowing the correct year helps you choose the right parts and diagrams for your Craftsman 917255933, especially for electrical items (like the ignition switch and solenoid), belts, and steering components.

If you need to order common electrical parts for this model, we list them by exact ID, such as the solenoid 532146154 and the lawn tractor ignition switch 532365402. For broader model searches and ordering, use Sears PartsDirect.

On a Craftsman front-engine lawn tractor model 917255933, the engine model number is typically stamped into the engine itself (not on the mower frame tag). Look for a metal-stamped code on the top of the engine near the cylinder head or valve cover area; it’s often easiest to see from the right or left side with the hood open.

Check these common locations first:

• Top of the engine shroud or blower housing (near the recoil or cooling fins)
• Valve cover area on either cylinder head (common on V-twin engines)
• Engine block near the spark plug(s)
• A sticker or metal tag near the starter or flywheel housing
• Under the hood along the engine’s upper surfaces (wipe off dirt and oil first)

We recommend recording all identification numbers you find, because parts lookups often need more than one code.

• Engine model number (the main identifier)
• Type/spec number (variant of the same engine model)
• Code/date (production code that can affect parts)

The mower model number 917255933 identifies the tractor, but the engine model number identifies the engine’s internal parts (like ignition components, fuel system parts, and starter-related items). Using the engine model number helps prevent ordering the wrong part.

If you’re troubleshooting a no-start or click-no-crank issue after identifying the engine, these resources and parts are commonly involved:

• Riding lawn mower engine clicks but doesnt turn over video
• Riding lawn mower engine wont turn over or click video
• Solenoid 532146154
• Lawn tractor ignition switch 532365402
