2 23915 23929 I'm here to explain how to use this manual. To get the most out of your manual, follow along carefully and read all the notes given by my assistant. This manual is divided into groups, with one group for each main area of the vehicle. By way of example, let's look at Group 21, which covers the clutch. We're here to help you. Group 21 Group 27 Group 31 Each group is divided into five parts, as shown below. Specifications Specifications, oil quantities, and other information pertaining to system components. Structure and Operation Information on the structure and operation of the overall system and its components. Troubleshooting An item-by-item guide to fault symptoms and their probable causes. On-Vehicle Inspection and Adjustment Instructions for on-vehicle inspection and adjustment operations. Service Instructions (See the next and subsequent pages.) The service instructions are the most important parts of this manual. Starting on the next page, you'll learn more about them.

First I look at the exploded view, then I look at parts to . Basically, you should find the information you need from parts to as you perform the service procedure. But how should I find the information I need? I'll show you on the next page. HOW THIS MANUAL IS STRUCTURED 3 4 5

5 5.9 {4.3, 0.6} 26314 20252 45204 Find the information you need using the key numbers. For example, let's assume you're assembling the clutch and need the tightening torque for the bolt . To find the tightening torque, just look up key number 1 in the “Tightening torques” table. I see... The key numbers for the exploded view match the key numbers on other parts of the page. To help you find information quickly: Tightening torques are marked with Ê . Lubricants, fluids and sealants are marked with - . And every key number that appears in the service procedure is enclosed with a square. 6 HOW THIS MANUAL IS STRUCTURED

CLUTCH-PROPER <C5> Pressure Plate-and-Lever Assembly ● Pre-disassembly operations Õ P21 - 44 • Disassembly sequence 1 Bolt 2 Lock plate 3 Support nut 4 Pressure spring 5 Pressure spring cap 6 Return spring 7 Release lever plate 8 Clutch cover 9 Release lever pin 10 Support lever pin 11 Support lever 12 Release lever 13 Bushing 14 Pressure plate P Positioning pin Ù : Non-reusable part NOTE Do not remove the bushing 13 unless it is defective. ● Assembly sequence Reverse the order of disassembly. Repair kit : Clutch release Lever kit ● Post-assembly Inspection and adjustment Õ P21 - 44 This mark indicates a part that cannot be reused. Pressure Plate-and-Lever Assembly This mark indicates that lubricant or sealant must be applied to the part. The key number enclosed with a square indicates that the part is men- tioned in the service procedure. This mark indicates that a tightening torque is specified for the part. So parts without Ê marks don't have specified tightening torques ? No, they don't. But every bolt and nut must be tightened to a standard torque. A Ê mark shows either that the part must be tightened to a torque other than the standard torque or that the standard torque cannot be determined from the part's shape or markings. Standard tightening torques are explained at the bottom of the next page. 2 3 - - 12 7 - 8 6 11 5 - Ù HOW THIS MANUAL IS STRUCTURED Exploded view 1 Ê 2 3 - - 12 7 - 8 6 11 5 - Ù 23925 23927 23928 1 8 23926 : Indicates positioning pin.

TABLE OF STANDARD TIGHTENING TORQUES ...................... ● Pre-disassembly operations Õ P21 - 44 ● Disassembly sequence 1 Bolt 2 Lock plate 3 Support nut 4 Pressure spring 5 Pressure spring cap 6 Return spring 7 Release lever plate 8 Clutch cover 9 Release lever pin 10 Support lever pin 11 Support lever 12 Release lever 13 Bushing 14 Pressure plate Ù : Non-reusable part NOTE Do not remove bushing 13 unless it is faulty. ● Assembly sequence Follow the disassembly sequence in reverse. Repair kit : Clutch Release Lever kit ● Post-assembly inspection and adjustment Õ P21 - 44 The key numbers are given here. This shows that certain operations must be performed before disassembly. The key numbers show the disassembly sequence. Links to reference information are given as follows: • Õ P21 - 44 Refer to the indicated page of the same group. • ^ Gr 42 Refer to the indicated group in another manual. The name of the specified repair kit (if any) is given here. The assembly sequence is given here. Assembly is usually performed in the opposite order to disassembly. If the assembly sequence is otherwise specified, it is given in terms of key numbers like this: ● Assembly sequence 14→12→10→13→11..... Now let's look at standard tightening torques. Normally, bolts and nuts have numbers or markings to show their material strength. Tightening torques for bolts and nuts with such numbers and markings are shown in the Table of Standard Tightening Torques that appears in group 00. INDEX ENGINE NUMBER AND NUMBER PLATE ................................................... + + + The names of parts are given here. 2 23930 This shows that certain operations must be performed after assembly.
