Craftsman 917275351 tractor Parts

On a Craftsman riding tractor like model 917275351, the engine model number is stamped on the engine itself (not on the mower deck or hood). Look for a metal-stamped code on the top area of the engine near the cylinder head or valve cover; it’s commonly on the right or left side.

Where to look on the engine

Check these common locations with a flashlight and a rag:

• Top of the engine near the cylinder head
• Valve cover area (right or left side)
• Blower housing or shroud area near the top
• Flat machined surface on the engine block
• Near the spark plug area

If the stamp is hard to see, wipe off oil and grass buildup; light rust can hide the characters.

Engine model number vs. tractor model number

These numbers are different and both can matter when ordering parts.

What you’re identifying	Where it’s found	What it’s used for
Tractor model number (917275351)	Tractor ID label (frame area)	Chassis, deck, steering, belts, electrical parts
Engine model number	Stamped into engine metal	Engine-specific parts (filters, ignition, carburetion, starter)

Why it matters

We use the engine model number to match the correct engine parts because the same Craftsman tractor model can be built with different engine versions over time.

For Craftsman model 917275351, the exact engine make and model varies by the tractor’s original build configuration; most Craftsman front-engine lawn tractors in this class use a single-cylinder gasoline engine in the mid-HP range. For a positive match, use the engine’s ID label on the blower housing or valve cover.

How to identify the engine on model 917275351

Use these quick checks to confirm what you have before ordering tune-up parts (air filter, spark plug, fuel filter) or troubleshooting a no-start.

• Look for an engine model/type/code sticker on the blower housing (top shroud) or near the valve cover.
• Write down the full string (letters and numbers); that is what parts lookups use.
• Check for a separate engine brand badge (common on Briggs & Stratton-powered units).
• If the label is missing, record the starter style, carburetor layout, and muffler position to help narrow it down.
• If the engine cranks slowly or only clicks, test the battery and cables before assuming the engine is locked up.

Common engine types you’ll see on Craftsman tractors like this

Most Craftsman riding mowers and lawn tractors similar to model 917275351 fall into one of these groups.

Engine type	What it usually looks like	What it affects most
Single-cylinder OHV	One spark plug, compact valve cover	Basic tune-up parts, carburetor style
V-twin OHV	Two spark plugs, wider engine	Different filters, different ignition parts

If it clicks or won’t crank, check these parts first

A “click” at the key often points to the starting circuit, not the engine itself.

• Battery charge and terminal corrosion
• Brake pedal and seat safety switches (interlock)
• Starter cable connections at the starter and solenoid
• Starter solenoid operation (a common failure item)

If you suspect the solenoid, we match it by model and circuit; see the lawn tractor starter solenoid 582042802.

Why it matters

The engine ID determines the correct maintenance parts and settings (spark plug type/gap, air filter style, fuel system parts). Confirming the engine first prevents wrong-part returns and speeds up repairs.

The Craftsman riding mower model 917275351 is typically associated with the mid-2000s era, most commonly around 2004 to 2006. Craftsman model years can vary by production run, so the most reliable way to pin down the exact year is to match the tractor’s product ID and engine tag details.

How to confirm the exact year on your tractor

Use these quick checks on your Craftsman 917275351 front-engine lawn tractor:

• Look for the model and product number label under the seat, on the frame rail, or near the rear fender pan.
• Record the product number (often a longer number than the model) and any date code on the label.
• Check the engine model/type/code on the engine shroud or valve cover; engine codes often narrow the build date.
• Compare your deck and chassis configuration to common mid-2000s LT-style tractors (axle style, deck size, tire size).
• If you are rebuilding the mower, matching major assemblies (deck, steering, drive) to the correct parts list also helps confirm the production family.

Why the year matters (parts and compatibility)

Craftsman tractors in the same model family can have small running changes that affect fit, especially for belts, deck hardware, and steering parts. Confirming the build window helps you avoid ordering a part that is close, but not correct.

Examples of parts where year and build variation can matter

System	Part type that often changes	Example part for this model
Mower deck	Mandrel and spindle assemblies	Lawn tractor mandrel housing 587819701
Blade drive	Deck belt length/profile	Lawn tractor blade drive belt, 7/16 x 90-1/4-in 532193214
Ground drive	Motion/drive belt length	V-belt 532138255

For a Craftsman front-engine lawn tractor model 917275351, we use 4-cycle engine oil; SAE 5W-30 is the most common all-season choice for reliable starting and protection in a wide range of temperatures.

Recommended oil type and when to use it

Most Craftsman riding mowers and lawn tractors use a standard 4-stroke (4-cycle) engine, so you want oil labeled for 4-cycle small engines.

• SAE 5W-30: best all-around option for mixed temperatures and easier cold starts
• SAE 10W-30: common for warmer weather use (can increase consumption in high heat)
• SAE SAE 30: typical for consistently warm temperatures (harder starting when cold)
• Use a quality oil that meets current API service ratings listed on the bottle

Quick checklist before you add oil

• Park on level ground and let the engine cool.
• Pull the dipstick, wipe it clean, reinsert, then recheck the level.
• Add oil slowly; overfilling can cause smoking and poor running.
• Replace the oil cap/dipstick fully before starting.

Oil selection at a glance

Your typical conditions	Oil viscosity to use	Why it matters
Cold starts and variable temps	SAE 5W-30	Faster lubrication at startup
Mostly warm weather	SAE 10W-30	Good protection in moderate heat
Hot weather only	SAE 30	Stable viscosity in heat

Why it matters

Using the right viscosity helps your tractor’s engine maintain oil pressure, reduce wear, and start easier. It also helps prevent overheating and oil burning during mowing season.

Yes, many Craftsman riding mowers use an engine with an oil filter, but it depends on the exact engine model installed on your Craftsman 917275351 lawn tractor. The quickest way to confirm is to look for a spin-on filter canister near the engine oil drain area and check the engine ID label.

How to tell if your 917275351 has an oil filter

Use these checks with the engine off and cool:

• Look for a small metal canister (spin-on style) mounted to the side of the engine block.
• Follow the oil fill tube or dipstick tube down; the filter is often nearby.
• Check for an oil filter adapter plate (a flat mount with a threaded stud).
• If you only see an oil drain plug and no canister or adapter, your engine is likely filterless.
• Confirm the engine make and model from the engine shroud label (common brands include Briggs and Stratton or Kohler).

What to do based on what you find

What you see on the engine	What it means	What we recommend
Spin-on canister filter	Oil filter equipped	Change oil and replace the filter at each service interval
No filter, no adapter	No oil filter	Change oil more frequently and keep the air filter clean
Adapter plate but no filter installed	Filter may be missing	Install the correct filter for the engine model

Why it matters

An oil filter helps trap fine debris that accelerates engine wear. If your engine does not use a filter, clean oil and on-time oil changes become even more important for long engine life.

Related maintenance and parts you may need

These parts are not oil-filter specific, but they are commonly involved when servicing or troubleshooting a riding mower:

• Molded ignition key 532140403 if the key is worn or intermittently loses contact
• Lawn tractor starter solenoid 582042802 if the engine clicks but will not crank
• V-belt 532138255 if ground drive performance is slipping after maintenance

A Craftsman mower labeled “6.75” is not one single model; it is an engine power class used on many different 21-inch walk-behind mowers. One known example is Craftsman model 917377911, but you must use the exact model number from your mower’s ID label to match parts.

How to find the correct model number

Check the mower’s product ID label (not the engine label). Common locations include:

• Rear of the mower deck near the discharge opening
• Top of the deck near the engine mounting area
• Behind the engine near the handle brackets
• Near the rear wheel height adjuster
• On the frame near the bagger mount (if equipped)

Why “6.75” is not enough

“6.75” identifies a power rating category, so different Craftsman mowers can share it but use different blades, wheels, cables, and drive components.

Marking you see	What it usually means	Good for parts lookup?
6.75 on the engine shroud	Engine power class	No
21-inch deck callout	Cutting width	Helps narrow, not exact
Full model number (example: 917377911)	Exact mower version	Yes

What to record before ordering parts

Once you find the model number, also note these details to avoid mismatches:

• Deck size (often 21-inch on 6.75-class mowers)
• Drive type (push vs. self-propelled)
• Blade type (standard, mulching, high-lift)
• Wheel size and hub style
• Engine brand and engine model (from the engine tag)

Why it matters

Using the full model number prevents ordering the wrong blade or drive parts and speeds up troubleshooting when the mower will not start, will not self-propel, or cuts unevenly.
