TRANSFER DISASSEMBLY

d6e031627500102


Before Service Precautions

•To prevent foreign material from entering the transfer, perform disassembly and servicing in a clean, dust-free environment.
•Inspect the each part while disassembling.
Warning
• The engine stand is equipped with a self-lock mechanism. However, if the transfer is tilted, the self-lock mechanism could become inoperative. This could cause the transfer to rotate accidentally, resulting in injury. Therefore, make sure that the transfer is not tilted when it is on the engine stand. When turning the transfer, grasp the rotation handle firmly.
