Will this pulley fit my mower model?

Compatibility covers several popular brands and deck sizes, but always compare dimensions and OEM numbers before ordering. The Caltric pulley corresponds to multiple manufacturer numbers so it fits Ferris, Simplicity, Snapper, and select Bad Boy Maverick decks listed below.

• Bad Boy OEM references: 033-8050-00, 039-6945-19, 039-6945-17, 039-6946-17
• Ferris and Simplicity equivalents: 5102678, 5104716YP (and related variants)
• Snapper fitment includes common 48" and 60" models cited in product specs

How do the pulley dimensions affect installation?

Accurate outer and inner diameters and flat width are essential for belt alignment and clearance inside the deck housing. This Caltric unit lists exact measurements so you can check the old pulley or the deck drawing to confirm a match before removing the old part.

• Outer diameter: 158.2 mm (6.22 in) — ensures correct belt wrap
• Inner diameter: 12.7 mm (0.50 in) — fits standard mounting shafts
• Pulley flat width: 27.1 mm (1.06 in) — matches belt profile
• Overall thickness: 40.4 mm (1.59 in) — clearance for spindle housings

What comes in the box and how quickly can I install it?

The package contains one split idler pulley ready for drop-in replacement. The split design means you can install it without removing surrounding components in many decks, cutting downtime during maintenance.

• Includes: 1x split idler pulley — ready to mount
• Installation: often performed with basic hand tools and minimal disassembly
• Tip: verify belt routing and tension after fitting to avoid premature wear

Is this pulley durable enough for heavy-use decks?

Caltric replacement parts are manufactured to match the mechanical and dimensional specifications of the original equipment. While no aftermarket part can promise the original supplier’s warranty, this pulley is intended for routine mowing conditions and regular maintenance intervals.

• Engineered to OEM size tolerances to preserve belt alignment
• Split style reduces installation strain on adjacent components
• Recommended to inspect bearings and mounts when replacing the pulley

Who is this for: This Caltric deck pulley is aimed at owners and service technicians of Ferris, Simplicity, Snapper, and Bad Boy Maverick mowers who need a direct-fit replacement for a worn or damaged split idler pulley. If your mower matches the listed models or OEM numbers and you want a dimensionally accurate aftermarket option for on-deck repairs, this part is suitable. Always confirm compatibility by checking the numbers and dimensions supplied with your current pulley; if you maintain multiple machines, keep original part numbers handy to speed correct selection.
