2. (a) 3. (a)

GENERAL DESCRIPTION This manual was created in accordance with SAE J2008. Generally repair operations can be separated in the following 3 main processes: 1. Diagnosis 2. Removing and Installing, Replacing, Disassembling, Installing and Checking, Adjusting 3. Final Inspection This manual explains” Removing and Installing, Replacing, Disassembling, Instaling and Checking, Adjusting”, but” Final inspection” is omitted. The following essential operations are not written in this manual, however these operations must be done in the practical situation. (1) Operation with a jack or lift (2) Cleaning of a removed part if necessary (3) Visual check INDEX An alphabetical INDEX is provided as a section on the end of the book to guide you to the item to be repaired. PREPARATION Use of special service tools (SST) and special service materials (SSM) may be required, depending on the repairing condition. Be sure to use SST and SSM when they are required and follow the working procedure properly. A list of SST and SSM is in the Preparation section in this manual.

Torque, oil applying position, and non-reusable parts are described as important points in the procedure. NOTICE: There are cases where such information can only be indicated by an illustration. In those cases, all the information such as torque, oil, etc. is described in the illustration. (e) Installing procedure of operation item is performed in the reverse order of the removal, and only the important points are described. (f) Only items with points are described in the procedure, and the operational portion and content are placed using an illustration. In the explanations, details of the operational method, standard value and notice are placed. (g) There may be cases where the illustrations of similar models are used. In those cases, the details may be different from the actual vehicle.
