NTB21-0132021-03-06. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; POWER TRAIN. PREVENT FRONT AXLE THREAD DAMAGE DURING NUT REMOVAL SERVICE INFORMATION If an Applied Vehicle needs to have a front axle nut removed, for any reason, the staking of the nut into the axle keyway must first be removed. The essential tool (part number # J-52982, Figure 1) required to remove the nut staking, is called out as a “Cape Chisel” in the Electronic Service Manual (ESM), and must be used to prevent thread damage to the axle (see Figure 2 on page 2). • The Cape Chisel arrived at dealers in December of 2020. • Damaged threads, due to improper removal of the stake placed in the nut, will not be covered by warranty. For information on using the Cape Chisel, refer to the Electronic Service Manual (ESM): Section TRANSMISSION & DRIVELINE > FRONT AXLE > REMOVAL AND INSTALLATION > FRONT DRIVE SHAFT > LH/RH.
