Before purchasing, compare the OEM numbers stamped on your existing spindle or consult your mower’s parts diagram. If the part numbers (for example 187292, 532187292, 192870, etc.) match any listed cross-reference, this ACEBRI assembly will be a compatible replacement.

• Check the original spindle’s part number against the cross-reference list

• Contact seller support via email with model and serial details for verification
