Keep your CAT 287D Final Drive Housings secured with a brand-new assembly nut! This assembly nut is also referred to as a Spanner Nut, Bearing Nut, or Lock Nut. The assembly nut threads onto the brake housing, sets the preload on the hub bearings and keeps your gearbox secured to the rest of the drive motor. We recommend replacing the original assembly nut if it has damaged threads or it was broken during disassembly.
This spanner nut is designed to directly replace the original CAT 287D Drive Motor Assembly Nut, ensuring exact OEM-like fitment.
