Craftsman 917276903 tractor Parts

On the Craftsman 917276903 front-engine lawn tractor, the engine is built from core internal parts (like the cylinder, piston, and crankshaft) plus supporting systems (fuel, ignition, lubrication, cooling, and exhaust) that work together to start, run smoothly, and deliver power to the drivetrain and mower deck. For model-specific service points and safety rules, use the 917276903 owner's manual.

Main engine parts (internal “hard parts”)

These parts create compression and convert combustion into rotating power:

• Cylinder block and cylinder head
• Piston and piston rings
• Connecting rod and rod bearings
• Crankshaft and main bearings
• Camshaft, lifters, and timing components
• Valves, valve springs, and valve guides

Supporting systems you will service most often

These systems are usually involved when a tractor will not start, runs rough, or loses power:

• Fuel system: fuel tank, fuel lines, fuel filter, carburetor (or injection on some engines)
• Ignition system: ignition switch, safety interlocks, coil/module, spark plug
• Lubrication: oil sump, oil pump (if equipped), oil filter (if equipped)
• Air intake: air filter, intake tube, choke linkage
• Charging/starting: battery, starter, starter solenoid
• Exhaust: muffler, spark arrester (where required)

Quick “what it does” reference

Engine area	What it does	Common symptom when it fails
Compression parts (piston/rings/valves)	Builds power	Hard starting, low power, smoke
Fuel + air	Feeds combustion	Surging, stalling, no-start
Ignition	Creates spark at the right time	Cranks but will not start
Lubrication	Prevents wear/overheating	Knocking, seizure risk
Starting circuit	Spins engine to start	Clicks, slow crank, no crank

Why it matters

Knowing which “system” a part belongs to helps you troubleshoot faster. For example, a no-crank problem often points to the starting circuit; on this model, a common service item in that circuit is the lawn tractor starter solenoid 582042802.

For Craftsman lawn tractor model 917276903, the operator’s manual lists a 26.0 HP tractor with electric start and a 54-inch mower deck. To identify the exact engine make and engine model (Briggs & Stratton, Kohler, etc.), match the numbers on the engine ID tag to the specifications in the 917276903 owner’s manual.

What the manual tells you for model 917276903

These are the key, model-specific details we use when confirming the tractor configuration:

• 26.0 HP engine rating shown on the manual cover
• Electric start
• 54-inch cutting deck size
• Operate the throttle at full speed (fast) for best mowing performance
• Use the choke for cold starts (do not use choke to stop the engine)

How to find the exact engine manufacturer and model

Craftsman tractors can be built with different engine suppliers; the engine tag is the deciding factor.

• Lift the hood and locate the engine ID label (often on the blower housing, valve cover, or near the starter)
• Record all numbers shown (commonly model, type/spec, and code/serial)
• Use those numbers to select the correct tune-up parts (spark plug, air filter, fuel filter)
• Cross-check the tractor’s configuration details in the 917276903 owner’s manual

Quick identification table

Item to check	Where you’ll see it	What it confirms
Tractor model number	Tractor frame tag (usually under seat or on frame)	You have model 917276903
Engine model/type/code	Engine ID label under hood	Exact engine make and model family
Deck size	Deck shell label or manual	54-inch deck configuration

Why it matters

The engine make and model determine the correct maintenance parts and settings. Using the wrong spark plug, air filter, or fuel filter can cause hard starting, rough running, and loss of power.

Craftsman “6.75” is an engine-size label used on multiple walk-behind mowers, so it is not a single model number. If you are asking about our Craftsman riding tractor shown here, the model number is 917276903; it’s a 26.0 HP, 54-inch front-engine tractor (see the 917276903 owner's manual).

How to identify the model number on a Craftsman 6.75 walk-behind mower

Use the equipment ID tag, not the engine decal.

• Look for a model/product label on the mower deck (often near the rear discharge area) or on the rear of the deck
• Write down the full model number and product number exactly as shown
• Record the serial number; it helps match the correct parts revision
• Use that model number to pull the correct diagrams for blades, belts, wheels, and controls

If you meant the Craftsman riding tractor model 917276903

This tractor’s model identification and key specs are listed in the manual.

• Model number: 917276903
• Engine rating shown in manual: 26.0 HP
• Mower deck size shown in manual: 54 in.
• Typical model tag locations: under the seat, on the frame rail, or near the engine compartment

You have	What “6.75” usually means	What 917276903 is
Walk-behind mower	Engine label used across many models	Not applicable
Riding lawn tractor	Not typically labeled “6.75”	26.0 HP, 54 in. deck

Why it matters

Parts are matched by the full model number, not the engine label. Using the correct model number prevents ordering the wrong blade, belt, ignition parts, or deck hardware.

Common parts people mix up on 917276903

If you are ordering tractor parts, match by diagram and location.

• Deck spindle and housing parts (mandrel area); example: lawn tractor mandrel housing 587819701
• Blade engagement electrical parts; example: switch.pto 582107601
• Starting circuit components; example: lawn tractor starter solenoid 582042802
