Craftsman 917273100 tractor Parts

For Craftsman lawn tractor model 917273100, the owner’s manual identifies the engine as a Kohler CV22S (type 75534) with 22.0 HP. This is a gasoline-powered, electric-start engine used on this specific front-engine garden tractor. See the 917273100 owner’s manual for the exact engine listing and specifications.

Knowing the exact engine family helps you match tune-up and fuel-system parts correctly (spark plugs, air filter, fuel filter) and follow the right oil and service intervals.

• Use fresh, regular unleaded gasoline; avoid storing fuel longer than about 30 days without stabilizer.
• Check engine oil before each use.
• Change engine oil about every 50 hours (or at least yearly).
• Clean the air filter and cooling fins regularly to prevent power loss and overheating.
• Replace spark plugs at the start of each mowing season or about every 100 hours.

Craftsman riding mowers can come with different engine brands and sizes (for example, Briggs & Stratton or Kohler) depending on the exact model number and production run. For 917273100, we recommend using the manual’s engine ID and the engine model tag on the tractor to confirm before ordering engine-specific parts.

Ordering the wrong engine parts is one of the most common causes of fit issues. Matching the engine model (Kohler CV22S) keeps your tune-up, fuel, and ignition parts aligned with how this tractor was built.

For Craftsman lawn tractor model 917273100, we recommend SAE 10W-30 4-cycle engine oil for temperatures above 32°F, and SAE 5W-30 for temperatures below 32°F. Use a high-quality detergent oil that meets API SF, SG, or SH specs (see the 917273100 owner's manual).

Your 917273100 uses a Kohler CV22S engine; the owner’s manual lists these oil specs:

• Above 32°F (0°C): SAE 10W-30
• Below 32°F (0°C): SAE 5W-30
• Oil rating: API SF/SG/SH (or equivalent)
• Change interval: every 50 hours of operation (or at least once per year)
• Check level: before each use and about every 8 hours of operation

Using the right viscosity helps prevent hard starting, overheating, and premature engine wear.

• Check oil on level ground before starting
• Do not overfill; fill only to the “FULL” mark on the dipstick
• Keep dirt out of the fill tube when adding oil
• Change oil more often in dusty conditions or heavy mowing
• Replace the oil filter as recommended for your usage pattern

Oil viscosity and API rating directly affect lubrication at startup and protection under load. On a 22 HP garden tractor like the Craftsman 917273100, the correct oil helps the engine run cooler and last longer.

On the Craftsman 917273100 front-engine lawn tractor, the engine includes the core internal components (crankcase, pistons, crankshaft, valves) plus the supporting fuel, ignition/starting, lubrication, air intake, and exhaust systems. For model-specific diagrams and specs, use the 917273100 owner's manual.

This Craftsman 917273100 uses a Kohler engine identified in the manual as Kohler model CV22S, type 75534. The manual also provides key service specs such as oil viscosity guidance and spark plug gap.

These are the main groups of parts you will typically see on a lawn tractor engine like the one on model 917273100:

• Crankcase/cylinder block: main engine housing for internal parts
• Crankshaft and bearings: turns piston movement into rotating power
• Pistons, rings, and connecting rods: create compression and transfer force to the crankshaft
• Cylinder heads and valvetrain: valves, springs, push rods, rocker arms
• Fuel system: fuel tank, fuel lines, fuel filter, carburetor, fuel pump
• Ignition/starting: spark plugs, ignition module/coil, starter motor, solenoid
• Lubrication system: oil pan, oil pump, pickup screen, oil filter (if equipped)
• Air intake/filtration: air cleaner housing, pre-cleaner, filter element
• Exhaust system: muffler, exhaust gaskets, spark arrester (if equipped)

Some “engine problems” are actually caused by belt-driven loads or safety circuits. Here are common service areas:

If the engine runs but the blades will not engage, a worn blade-drive belt can be the real issue; one compatible belt listed for this model is the lawn tractor v-belt 532144959.

Knowing which system a part belongs to helps you troubleshoot faster. Most running issues trace back to fuel, air, ignition, or a load problem (like a belt or deck issue) rather than internal engine damage.
