What are the parts of a tractor engine?
On the Craftsman lawn tractor model 917270711, the engine is built from core systems that make power (cylinder, piston, crankshaft), control airflow (valves), create spark (ignition), and keep everything lubricated and cooled. For your exact engine breakdown, use the illustrated parts list in the 917270711 owner's manual.
Main engine assemblies you will see
Most front-engine riding mower engines (including the Briggs & Stratton engine used on 917270711) are organized into these major groups:
- Cylinder block and crankcase: the main engine body that supports moving parts
- Piston and piston rings: compress the air-fuel mixture and transfer force to the crankshaft
- Connecting rod and bearings: link piston motion to the crankshaft smoothly
- Crankshaft and flywheel: convert up-and-down motion into rotation; flywheel helps maintain momentum
- Valve train (camshaft, valves, springs, rocker arms): controls intake and exhaust timing
- Ignition system (magneto/armature, spark plug, stop wire): creates spark and shuts the engine off
- Fuel and air system (carburetor, fuel filter, air cleaner): meters fuel and supplies clean air
Common service parts called out for this model
The manual’s engine parts list for 917270711 includes items you may replace during tune-ups or no-start troubleshooting:
| Part type | What it does | Typical symptom when failing |
|---|---|---|
| Spark plug | Ignites the air-fuel mix | Hard starting, misfire |
| Starter motor | Cranks the engine | Clicks but no crank |
| Alternator | Charges the battery | Battery goes dead |
| Gasket set | Seals engine joints | Oil leaks, poor running |
Why it matters
Knowing which system you are working on helps you diagnose faster. For example, a “click but no crank” points you toward the battery, wiring, solenoid, or starter, while “cranks but won’t start” points more toward spark, fuel, or air.
Quick tip for finding the exact parts on your tractor
Use the engine model and type information listed for 917270711 in the 917270711 owner's manual; then match the diagram callouts to the part names when ordering.

What model number is the Craftsman 917270711 engine?
For the Craftsman lawn tractor model 917270711, the engine is a Briggs & Stratton model 311707, type 0132-E1. You will use that engine model and type when looking up engine-specific parts such as the starter, carburetor, ignition, and gaskets in the 917270711 owner's manual.
Where to find the engine model and type
We recommend confirming the numbers in two places so you order the right parts:
- The engine ID label on the engine shroud or valve cover area (often shows MODEL, TYPE, and CODE)
- The tractor documentation and engine breakdown section
- The engine parts list when identifying items like the starter motor, spark plug, or fuel system parts
Why the engine “type” number matters
Briggs & Stratton uses the type number to identify the exact build configuration. Two engines can share the same model number but use different carburetors, mufflers, or ignition parts.
Common examples where the type number changes the part:
- Carburetor and choke linkage
- Starter motor and drive
- Muffler and exhaust gasket
- Air cleaner base and filter style
Quick reference

What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917270711, we use a high-quality detergent 4-cycle engine oil that meets API service classification SF, SG, or SH, and we choose the SAE viscosity based on the outdoor temperature (the manual includes an oil viscosity chart for seasonal selection). See the 917270711 owner's manual for the exact viscosity recommendation by temperature.
What to use (and what to avoid)
Use oil that matches these basics for this Craftsman riding mower engine:
- 4-cycle (4-stroke) detergent engine oil
- API rating: SF, SG, or SH (or newer equivalents that meet/exceed these)
- SAE viscosity: pick based on expected operating temperature (summer vs. cold weather)
- Clean oil at the proper level: keep it at the FULL mark on the dipstick
- Avoid overfilling, which can cause smoking, fouled plugs, and performance issues
How to check the oil level correctly
We recommend checking oil before each mowing session, with the tractor on level ground:
- Park on a level surface and set the parking brake
- Remove the oil fill cap/dipstick, wipe it clean
- Reinsert and tighten the cap, wait a few seconds
- Remove again and read the level
- Add oil slowly until it reaches the FULL mark (do not overfill)
Quick guide: choosing viscosity by season
Your manual’s viscosity chart is the best match for your climate. As a practical rule:
| Typical conditions | Common choice | Why it’s used |
|---|---|---|
| Warm-weather mowing | SAE 30 (common “summer weight”) | Stable protection at higher temps |
| Cold-weather starting | 5W-30 (common multi-viscosity) | Easier cranking and faster lubrication |
Why it matters
Correct oil type and viscosity protect the crankshaft, piston, and valve train from wear. On a riding lawn tractor like the Craftsman 917270711, the right oil also helps prevent hard starting in cold weather and power loss when the engine is hot.
