 2. INDEX
      a. An alphabetical INDEX is provided as a section on the end of the book to guide you to the item to
         be repaired.
 3. PREPARATION
      a. 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.
 4. REPAIR PROCEDURES
      a. Component drawing is placed as the section or title if necessary.
      b. Illustrations of the parts catalog are placed as the" disassembled parts drawing" so that it enables
         you to understand the fitting condition of the components.
      c. Non-reusable parts, grease applied parts, precoated parts and torque are specified in the components
         drawing.
          Example:
    Fig. 1: Identifying Components Nonreusable Parts
                                                                                                       cardiagn.com

 d. Torque, oil applying position, and non-reusable parts are described as important points in the
    procedure.
     NOTE:           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.
 h. The procedures are presented in a step-by-step format:
       1. The illustration shows what to do and where to do.
       2. The task heading tells what to do.
       3. The detailed text tells how to perform the task and gives other information such as
           specifications and warnings.

 7. SI UNIT
      a. The UNITS used in this manual are primarily expressed according to the SI UNIT (International
         System of Unit), and alternately expressed in the metric system and in the English System.
Example:
PRECAUTION
1. BASIC REPAIR HINT
     a. PRECOATED PARTS
          1. Precoated parts are bolts, nuts, etc. that are coated with a seal lock adhesive at the factory.
          2. If a precoated part is retightened, loosened or caused to move in any way, it must be recoated
             with the specified adhesive.
          3. When reusing precoated parts, clean off the old adhesive and dry with compressed air. Then
             apply the specified seal lock adhesive to the bolt, nut or threads.
                                                                                                         cardiagn.com
                Fig. 3: Sealing Lock Adhesive
                Courtesy of TOYOTA MOTOR SALES, U.S.A., INC.
                NOTE:           Do the torque checking with the lower limit value of the torque
                                tolerance.
          4. Depending on the seal lock agent to apply, there may be a case where it is necessary to leave '
             it for a specified time until it hardens.
      b. GASKETS
         Carefully observe all specifications for bolt tightening torques. Always use a torque wrench.
d. TORQUE WHEN USING EXTENSION TOOL WITH TORQUE WRENCH
     1. In case of tightening by extending the entire length of the torque wrench combined with SST
        or tool, if you tighten until the reading of the torque wrench reached the specified torque
        value, the actual torque becomes excessive.
     2. In this text, only the specified torque is described. In case of using SST or extension tool,
        find the reading of the torque wrench by the formula.
     3. Formula T'=T x L2/(L1 + L2)

                      group at a time. This avoids the possibility of switching similar-looking
                      parts from different sub-assy. The component groups are inspected and
                      repaired from the converter housing side. As much as possible, complete
                      the inspection, repair and reassembly before proceeding to the next
                      component group. If a defective part is found in a component group during
                      reassembly, inspect and repair the part immediately. If a component group
                      cannot be assembled because parts are being ordered, be sure to keep all
                      parts of the group in a separate container while proceeding with
                      disassembly, inspection, repair and reassembly of other component
                      groups.
Recommended ATF: WS
                     All disassembled parts should be washed clean, and any fluid passages
                      and holes should be blown out with compressed air.
                     Dry all parts with compressed air-never use a shop rag.
                     When using compressed air, always aim away from yourself to prevent
                      accidentally spraying ATF or kerosene on your face.
                     The recommended automatic transmission fluid or kerosene should be
                      used for cleaning.
                     After cleaning, the parts should be arranged in the correct order for
                      efficient inspection, repairs, and reassembly.
                  Using a razor blade and a gasket scraper, remove all the old packing
                  (FIPG) material from the gasket surface.
                                                                                                 cardiagn.com
                  Thoroughly clean all components to remove all the loose material.
