Upgrade 499901 Pulley Spring Assy Replacement for Briggs & Stratton Lawn Mower Starter Recoil Pulley #499897 OEM Parts 5-Year Warranty

What It Is

This is an aftermarket pulley spring assembly for Briggs & Stratton recoil starters. It replaces the OEM part #499901 and the pulley #499897, used to rewind the starter rope on walk-behind mowers and some small engines.

Fitment & Compatibility

• Direct fit for Briggs & Stratton engines with the 499901 spring assembly or 499897 pulley.
• Check your engine model – common on 450, 500, 550, 625, 675, 725, 750, 775, 850, and 875 series (and many others with the same starter housing).
• Measure the pulley diameter – OEM is ~3.5 inches (89mm). If yours differs, it won’t fit.
• Not universal – won’t work on Tecumseh, Honda, Kohler, or other brands unless they use the same Briggs-style starter.
• Aftermarket vs OEM – this is a non-OEM replacement; verify the spring hook and pulley shape match your old part before buying.

Key Things to Know

• Installation difficulty – moderate. You’ll need a screwdriver, pliers, and patience to wind the spring without it snapping loose.
• Quality note – some users report the spring is slightly weaker than OEM, but it holds up fine for seasonal use.
• Common gotcha – the spring can pop out during installation. Wear safety glasses and wind it slowly in a clean area.
• 5-year warranty – covers defects, but not damage from improper installation or overtensioning.

Should You Buy It

If your Briggs starter rope won’t retract or the pulley is cracked, this is a budget-friendly fix. It’s best for DIYers comfortable with small engine repair and who want to avoid a full starter assembly replacement. For commercial or heavy daily use, consider OEM for tighter spring tension and longer life.
