Craftsman 102273920 lawn tractor Parts

For the Craftsman riding lawn tractor model 102273920, a typical engine replacement (parts plus labor) runs about $260 to $1,800. Total cost depends on the engine type, whether you replace a complete engine or internal components, and local shop labor rates.

We see engine replacement pricing swing widely based on these factors:

• Engine choice: new complete engine vs. rebuilding the existing engine
• Labor time: riding mower engine swaps commonly take several hours
• Extra parts: belts, pulleys, wiring repairs, fuel system cleanup
• Root cause: overheating, low oil damage, or a seized crankshaft can add work
• DIY vs. shop: DIY saves labor but requires tools and safe lifting/handling

If the engine still has good compression and the issue is limited, repairing can cost less than a full engine swap.

Many “bad engine” symptoms are caused by starting or safety issues. Check these first:

• Battery charge and cable connections
• Starter solenoid and starter operation
• Fuel quality (old fuel, water in fuel)
• Spark and air filter condition
• Safety interlocks (seat switch, brake switch, neutral switch)

A common no-crank culprit is the safety circuit; on this model, the lawn tractor neutral switch 01522000 is one example of an interlock component that can prevent starting when it fails.

An engine is one of the highest-cost repairs on a riding mower. A quick diagnosis can prevent replacing the engine when the real problem is a safety switch, battery issue, or drive component.

To look up the model number for your Craftsman riding mower, find the model and serial tag on the tractor first; on model 102273920, it’s typically on the frame under the seat or on the underside of the seat, then use that exact number when searching parts.

Check these common locations on Craftsman front-engine lawn tractors:

• On the frame directly under the seat (lift the seat to look)
• On the underside of the seat pan
• Near the rear fender area close to the seat mounting points
• On a sticker or metal plate; wipe off grass and oil to read it clearly

Use the model number exactly as printed (including any dashes or extra digits) to ensure the right diagrams and parts list.

• Search by the full model number first (example: 102273920)
• Use the serial number to confirm production run when parts vary by revision
• Match the part description to the diagram location before ordering
• If a part is missing hardware, replace fasteners with the correct size and grade

Craftsman lawn tractors often have multiple versions that look similar; using the exact model number prevents ordering the wrong deck, steering, or drive components and saves time on returns.

If you’re already on the correct model, you can jump straight to common replacement items like the lawn tractor neutral switch 01522000 when troubleshooting no-crank or safety-interlock issues.

Yes, it’s worth replacing the engine on your Craftsman lawn tractor model 102273920 when the tractor is otherwise in solid shape and the total repair cost stays well below the price of a comparable replacement mower. If the engine swap pushes you near half the mower’s value, replacement usually makes more sense.

• The deck, steering, and frame are straight and not heavily rusted
• The transmission drives smoothly (no slipping, whining, or loss of power)
• You can confirm the replacement engine is compatible (shaft size, mounting pattern, wiring)
• You plan to keep the tractor at least 2 to 3 more seasons
• You can do the work yourself or have a shop you trust

A practical way to decide is to compare the all-in engine replacement cost (engine, belts, hardware, labor) to the mower’s current value.

Engine replacement is a bad investment if other high-cost systems are also worn.

• Drive system: check for weak drive, leaks, or noisy bearings
• Deck system: inspect mandrels, pulleys, and spindle play
• Safety interlocks: confirm the tractor starts and runs correctly with switches engaged
• Steering and front end: check for looseness and uneven tire wear
• Parts condition: look for damaged pulleys or worn linkages that caused the failure

Helpful model-related parts to check while you’re in there include the lawn tractor neutral switch 01526100 (no-start and safety circuit issues) and the Craftsman lawn tractor engine pulley 07325500 (belt alignment and drive engagement).

An engine swap can restore reliable mowing, but it only pays off when the rest of the Craftsman 102273920 tractor is not close to needing a transmission, deck rebuild, or major steering repair.

For the Craftsman lawn tractor model 102273920, the exact engine make and model varies by build and configuration; most Craftsman front-engine riders in this class commonly use a single-cylinder gasoline engine in the 17 to 20 HP range. We recommend confirming by checking the engine ID tag on your mower.

Look for the engine identification label (usually on the blower housing, valve cover, or near the starter). Record these items:

• Engine brand (often Briggs & Stratton, Kohler, or similar)
• Engine model number
• Type and code numbers (common on Briggs & Stratton)
• Spec number (common on Kohler)
• Serial number

Even when the tractor model is 102273920, engine parts must match the engine tag, not just the tractor model.

• Compare the engine tag numbers to the listing on the part packaging
• Match pulley and belt routing before swapping any drive components
• Inspect the crankshaft area for oil leaks or wobble before replacing pulleys
• Verify safety interlocks are working if the engine will not crank
• Check battery condition and cable connections if you only hear clicking

These parts are commonly involved when diagnosing “won’t crank,” “belt slips,” or “no drive” symptoms:

Using the correct engine identification prevents ordering the wrong carburetor, starter, air filter, spark plug, or tune-up parts. The tractor model tells us the chassis and deck family; the engine tag tells us the exact engine parts.

Craftsman model 102273920 is commonly associated with the LT 1000 series, which was produced in the early 1990s, with many references pointing to 1991 through 1993 for that model run. For parts accuracy, we match by the full model number and the exact tractor configuration.

The most reliable way to pin down the exact year is to use the identification information on the tractor itself.

• Check the model/serial tag (typically under the seat, on the frame rail, or near the engine)
• Write down the full model number (102273920) and the serial number
• Look for a date code on the engine label (engine date can be close to tractor assembly date)
• Compare your deck and drive layout to the parts diagrams for this model
• If your tractor has had major assemblies swapped (engine, transaxle, deck), date clues can differ

Craftsman riding mowers often keep the same model family name (like LT 1000) while changing components mid-run. The year range helps, but the model number and serial are what prevent ordering the wrong belt, pulley, or safety switch.

If you are comparing diagrams or troubleshooting fitment, these model-specific parts are good reference points:

• Lawn tractor neutral switch 01522000 (starting and safety interlock circuit)
• Craftsman lawn tractor engine pulley 07325500 (belt routing and drive engagement reference)
• Craftsman adjustment link 03486400 (deck height or linkage configuration reference)

If your goal is to order parts (not just identify the year), we recommend matching by model number + serial number + deck size (if known). That combination is what keeps you from getting the right part for the wrong LT 1000 variation.

On a Craftsman lawn tractor like model 102273920, the product date code is typically found on the equipment identification label (often under the seat, on the frame rail, or near the engine). For Craftsman batteries and many chargers, the date code is commonly printed or engraved on the housing.

Look for a white or silver sticker or stamped tag that includes the model number and serial information.

• Under the seat pan or on the seat support bracket
• On the frame rail near the rear wheels
• In the engine compartment near the engine shroud
• Near the steering column or dash tower
• On the transaxle area or rear frame crossmember

Many Craftsman batteries use a 6-digit date code printed or engraved on the plastic case (often on top). Chargers often have the date code on the bottom label.

The date code helps us match the correct parts and specs for your tractor, especially when there are mid-year changes to items like belts, pulleys, and safety switches.

If you are troubleshooting a no-start condition tied to the safety interlock system, the neutral safety circuit is a common checkpoint; the lawn tractor neutral switch 01526100 is one of the interlock components used on this model.
