Craftsman 917377041 lawn mower Parts

On a Craftsman walk-behind mower like model 917377041, the model number is typically printed on the mower’s identification label on the rear of the deck, near the lower handle mounting area. Match that number exactly when ordering parts or using the 917377041 owner's manual.

Where to look on the mower

Check these common label locations first:

• Back of the mower deck, between the lower handle mounts
• Rear deck panel just above the discharge area
• Near the height-adjuster brackets on the deck (less common)
• On a worn label, the model number may be faint; use a flashlight and wipe off dirt

What to write down (and why)

For the best parts match, record the full ID information from the label.

• Model number (example: 917377041)
• Serial number (helps confirm production run)
• Engine model (this mower uses a Honda GCV160 series engine per the manual)
• Any extra suffixes or revision codes printed after the model number

Quick ID checklist

Item on label	What it’s used for	Example
Model number	Correct parts diagrams and assemblies	917377041
Serial number	Confirms exact build/version	Varies
Engine model	Engine-specific tune-up parts	Honda GCV160

Why it matters

Craftsman walk-behind mowers often share similar decks and controls across multiple models, but small differences (drive cable routing, wheel hardware, blade brake and clutch setup) can change the exact replacement part you need. Using the exact model number prevents ordering the wrong blade, drive parts, or hardware.

For the Craftsman walk-behind mower model 917377041, we recommend using regular unleaded 87-octane (87 AKI) gasoline for normal operation. Higher octane (like 91) does not add power or improve reliability in a typical small mower engine; fresh, clean fuel matters more.

What to use (and what to avoid)

• Use fresh, clean unleaded gasoline (87 AKI).
• Avoid old fuel; stale gas is a top cause of hard starting and rough running.
• Avoid high-ethanol blends when possible; ethanol attracts moisture during storage.
• Do not mix oil into the gas unless your engine is specifically a 2-cycle design (most walk-behind mowers like this are 4-cycle).
• If the mower will sit, add fuel stabilizer and run the engine briefly to circulate treated fuel.

Quick fuel guidance table

Fuel choice	OK to use?	When it makes sense
87 octane (regular)	Yes	Everyday mowing and best overall choice
89 octane (mid-grade)	Yes	Fine if that is what you have available
91+ octane (premium)	Yes	No real benefit for mowing; use only if already in your can
Old/stale gas	No	Drain and replace with fresh fuel

If your mower runs poorly after fueling

These checks solve most “bad gas” symptoms on model 917377041:

• Drain the tank and refill with fresh gasoline.
• Check and replace the spark plug if starting is inconsistent.
• Clean or replace the air filter if the engine surges or smokes.
• Verify the fuel valve lever (if equipped) is in the ON position.
• Review the fuel and starting steps in the 917377041 owner's manual.

Why it matters

Using the correct fuel helps prevent hard starting, surging, and carburetor varnish. The manual’s troubleshooting guidance also points to fresh gasoline and basic tune-up items (air filter, spark plug) as key fixes when the engine will not start or runs rough.
