033-5001-00 Parts Lawn Mower Flat Idler Pulley 033-5000-00 Compatible with Bad Boy Most CZT Elite, Ou tlaw XP, MZ Mag num, Renegade Stand-On Revolt Steel

What It Is

The 033-5001-00 is a flat idler pulley that routes and tensions the deck drive belt on select Bad Boy zero-turn mowers. It replaces OEM part 033-5000-00 and is used on mowers with 48" to 72" decks.

Fitment & Compatibility

This pulley fits Bad Boy CZT Elite, Outlaw XP, MZ Magnum, Renegade, and Revolt models, but not all years or deck sizes. Before buying:

• Check your OEM part number: Look for 033-5000-00 stamped on your old pulley. If yours is different, this won’t work.
• Measure the pulley: This is a 4.0" diameter flat pulley with a 5/8" bore. Confirm your deck uses that size—some Bad Boy decks use 3.5" or 4.5" pulleys.
• Verify your deck size: This pulley is common on 54" and 60" decks. 48" and 72" decks may use different pulleys.
• Count how many you need: Some decks use two flat idlers. Buy two if your deck has two.

Key Things to Know

• Aftermarket quality is solid – This is a non-OEM replacement but uses sealed ball bearings and a steel hub. Most users report it lasts as long as the original.
• Easy swap, but check the bearing – Installation takes 10 minutes with a wrench. Spin the pulley by hand before mounting—if it feels gritty or rough, return it.
• Common gotcha: belt routing – After replacing, double-check belt routing against your deck diagram. A misrouted belt will shred the new pulley quickly.
• No spacers included – Reuse the old spacer or washer from your original pulley. If yours is missing, you’ll need to source one separately.

Should You Buy It

If you need a direct-fit replacement for a worn or noisy idler pulley on a compatible Bad Boy model, this is a reliable, budget-friendly choice. Avoid it if your deck uses an odd-size pulley (3.5" or 4.5") or if you need an OEM part for warranty purposes. For the price, it’s a no-brainer for most DIY repairs.
