Parts for Craftsman 917371490: Wheels / Tires / Bag Parts

This jet holder mounts in the burner assembly for a 12,000 BTU burner. It positions and secures the orifice (jet) and helps seal and align the gas path so the burner lights reliably and produces a steady flame.

• Holds and aligns the burner orifice for the 12,000 BTU burner
• Provides a sealed passage from the valve to the burner head
• Helps restore proper flame height and pattern when the original holder is stripped, cracked, or corroded
• Common symptoms: weak or uneven flame, burner won't light, or jet/orifice will not seat securely

• Shut off gas supply and power; allow the appliance to cool before starting
• Remove grates, burner caps, and burner head to access the holder
• Transfer the existing orifice/jet to the new holder; tighten fittings carefully—do not overtighten into soft metal
• Reassemble, restore gas, and perform a leak check with an approved solution

This OEM part is a mulcher mower blade for lawnmowers. The mulcher mower blade is the blade assembly that is used to cut grass in a lawnmower. Over time, the mower blade can deteriorate, becoming dull and ineffective with extended use. If it's been a while since the blade has been replaced, it might be time for a new one. Luckily replacing a mower blade is a relatively simple process. Before beginning, the engine cool and wear work gloves. Disconnect the spark plug wire from the spark plug and remove the fuel tank cap. Place a plastic bag over the fuel tank opening and reinstall the fuel tank cap to keep gasoline from leaking out of the fuel tank cap vent. Tilt the mower back to lift the front wheels and secure the mower handle to a work table to hold the motor steady. Wedge a block of wood between the mower blade and the deck to keep the blade from turning when loosening the blade bolt. Loosen and unthread the blade bolt while holding the cutting blade to keep it from falling. Pull the blade, blade support, and blade bolt off the crankshaft. Make sure to position the new parts on the crankshaft. Hand-tighten the new blade and bolt onto the crankshaft. Use a torque wrench to tighten the blade bolt. This genuine replacement part is compatible with MTD brand lawnmowers.
