(2 Pack) 174356 46" 48" Deck Mower Spindle Assembly for AYP 174358 532174356, for Husqvarna Z246 YTH1848XP YTH2448 YTH2748,for Craftsman GT5000 48" Lawn Tractor, for AYP 48" Decks 2002 & Newer

What It Is

This is a 2-pack of replacement mower spindle assemblies designed for 46" and 48" AYP (American Yard Products) decks used on Husqvarna, Craftsman, and other lawn tractors from 2002 and newer. The spindle houses the blade mounting shaft and bearings, transferring power from the belt to spin the blades.

Fitment & Compatibility

Deck size: Fits 46" and 48" AYP fabricated decks only—do not use on stamped steel decks.
OEM cross-reference: Replaces AYP 174356, 174358, 532174356, 532174358.
Brand fit: Husqvarna models Z246, YTH1848XP, YTH2448, YTH2748; Craftsman GT5000 48" and other AYP 48" decks from 2002 onward.
Critical check before buying: Measure the spindle shaft diameter (must be 1" for most AYP decks) and the mounting hole pattern (typically 4-bolt, 3.5" center-to-center). Verify your deck has the cast-iron/steel spindle housing vs. a plastic one. This is a 2-pack—you need two spindles for a 48" deck (one for each blade).

Key Things to Know

• Quality vs. OEM: These are aftermarket spindles. They work fine for residential use but may use lower-grade bearings than OEM Husqvarna/Craftsman parts, so expect shorter lifespan under heavy use.
• Installation: Moderate difficulty—requires removing the deck, pulleys, and blade. Use a torque wrench on the spindle nut (typically 40-50 ft-lbs). The included bearings are pre-greased, but adding a dab of grease during install helps.
• Common gotcha: The spindle pulley may not match your original if you have a different belt routing (e.g., some 48" decks use a 3.5" vs. 4" pulley). Check pulley diameter before buying or reuse your old pulley.
• Deck compatibility: Only fits AYP “fabricated” decks (flat, welded steel). Does not fit stamped decks (curved, one-piece) common on older Craftsman models.

Should You Buy It

Buy this if you have a 2002+ AYP 46" or 48" fabricated deck on a Husqvarna or Craftsman tractor and want a budget-friendly 2-pack for a DIY spindle swap. Skip it if you have a stamped deck, need OEM-grade durability for commercial mowing, or your old spindles have a different pulley size—those cases call for a single OEM spindle or a matched set.
