In-Vehicle Service Procedures How to Remove the Auxiliary Section in Chassis Special Instructions The following procedure covers the removal of the auxiliary section with the transmission remaining in the chassis. If the transmission has been removed, refer to “Auxiliary Section Removal (Bench Procedure)” for removal procedures. CAUTION: The lock cover was removed on new units, so the shiftbar needs to be removed to unlock the range cylinder and remove the auxiliary section.

Drain the transmission oil.

Disconnect the driveshaft and U-joint from the output yoke.

If the auxiliary section is to be disassembled, remove the output nut using a 70 mm or 2 3/4” socket. To prevent the output shaft from rotating while removing the nut, shift the transmission to 1st gear or use a yoke holding tool. WARNING
