Xiaoyudou Flat Idler Pulley 3-Pack for Bad Boy ZT/Outlaw/MZ Decks — 1/2" Bore, 5-3/4" OD, Durable Metal

Three high-strength flat idler pulleys engineered to replace worn originals on Bad Boy ZT, Outlaw and MZ series decks. Keep your mower's belt routing steady and reduce downtime with this 3-pack of flat idler pulleys by Xiaoyudou, built to match the critical dimensions of several Bad Boy OEM parts. Each pulley is manufactured from durable metal, precision-machined to fit the same shafts and spacings as the factory components, and tested for wear resistance before shipment. The set covers commonly replaced part numbers and suits multiple deck sizes so you can service more than one machine without ordering separate parts.

Which Bad Boy models and OEM numbers does this replace?

These pulleys are made to substitute specific Bad Boy factory part numbers across ZT, Outlaw and MZ series decks. They directly align with the listed OEM references so you can be confident they’ll fit without modification.

• Replaces BAD BOY 033-7201-25, 033-7201-00, 033-2000-00, 033-8000-00.
• Compatible with ZT Series decks: 48", 50", 54" and 60".
• Compatible with Outlaw decks: 54", 61" and 72".
• Fits MZ Series decks: 48" and 54".

What are the exact dimensions and why do they matter?

Correct pulley measurements ensure correct belt alignment and tension, preventing premature belt wear and reducing vibration. Xiaoyudou supplies the pulleys to match the original spatial and bearing requirements so the belt runs smoothly in the factory routing.

• Overall width: 1-1/2" for proper belt contact area.
• Outer diameter (ID): 5-3/4" to match original belt path geometry.
• Center bore: 1/2" for direct mounting on the existing shaft.

How difficult is installation and what tools will I need?

Installation is straightforward when you follow basic mower maintenance steps; the pulleys are built to OEM tolerances so they slip into the original mounts. Typically you only need hand tools and basic safety precautions to swap them out, and no machining or special adapters are required.

• Standard wrenches or sockets to remove mounting hardware.
• Belt tension relief (by disengaging deck or tensioner) to remove the belt safely.
• Anti-seize or light thread locker recommended on bolts for secure reassembly.

What materials and durability can I expect from these pulleys?

Manufactured from high-hardness metal and surface-treated for corrosion resistance, these idler pulleys are intended to withstand the abrasion and load typical of mower deck duty. Each unit is inspected before shipping and designed to resist deformation under normal operating conditions.

• High-hardness metal construction for wear resistance.
• Surface treatment to reduce corrosion in wet grass conditions.
• Factory testing to verify concentricity and fit before packing.

This 3-pack is ideal for landscape pros, fleet managers, and do-it-yourself mower owners who maintain Bad Boy ZT, Outlaw, or MZ series decks. Buy the set to replace multiple worn pulleys at once, keep a spare on hand for quick roadside fixes, or restock parts for seasonal maintenance. Xiaoyudou supports the product with a two-year warranty and customer support if you run into fitment questions or need assistance during installation.
