If your Toro mower deck is making noise or the belt keeps jumping off, you might need a new idler pulley.
![]()
This one is a direct replacement for the Toro part numbers 117-5299 and 46-5650.

It's made by Rotary, and it's the exact size you need: 15/32 inch bore by 2-7/8 inch outer diameter.

It's designed for 21' BBC (maybe they meant 21-inch) mowers, but double-check your measurements.

It comes as a single pulley, brand new in the package.

Just pop the old one off, bolt this one on, and get back to mowing.

It's a simple fix that can save you a lot of hassle with belt slippage.
