GI IMPORTANT tNFORMATlUN IMPORTANT INFORMATION 1 .ftl 1 BASIC ASSUMPTIONS This workshop manual assumes that you have certain special tools that are necessary for the safe and effi- cient performance of service operations on Mazda vehicles and that you know how to use them properly. It also assumes that you are familiar with automobile systems and basic service and repair procedures. You should not attempt to use this manual unless these assumptions are correct and you understand the conse- quences described below. SAFETY RlSK This manual contains certain notes, warnings, and other precautionary information that you should carefully read and follow to reduce the risk of personal injury to yourself or others and the risk of improper service that may damage the vehicle or render it unsafe. If there is no such information in regard to any specific service method, this does not mean there is no possibility that personal safety or vehicle safety will be jeopardized by the use of incorrect methods or toots. POSSIBLE LOSS OF WARRANTY The manufacturer’s warranty on Mazda vehicles and engines can be voided if improper service or repairs are performed by persons other than those at an Authorized Mazda Dealer. WARNING ON LUBRICANTS AND GREASES ’ Avoid all prolonged and repeated contact with mineral oils, especially used oils. Used 08s contaminated during service (e.g., engine sump oils) are more irritating and more likely to cause serious effects, including skin cancer, in the event of gross and prolonged skin contact. Wash skin thoroughly after work involving oil. Protective hand cleaners may be of value provided they can be removed from the skin with water. Do not use gasoline, paraffin, or other solvents to remove oil from the skin. Lubricants and greases may be slightly irritating to the eyes. Repeated or prolonged skin contact should be avoided by wearing protective clothing if necessary. Particu- lar care should be taken with used oils and greases containing lead. Do not allow work clothing to be contaminated with oil. Dry clean or launder such clothing at regular intervafs. 9MUGiX-502

Begin work only after first learning which parts and subassem- blies must be removed and disassembled for replacement or repair. 1 47ilOGX-006 1 DISASSEMBLY If the disassembly procedure is complex, requiring many parts to be disassembled, all parts should be disassembled in a way that will not affect their performance or external appearance and identified so that reassembly can be performed easily and efficiently. t 9MlJGIX439

GI FUNDAMENTAL PROCEDURES 9MUGtX-040 SMLIGIX-041 SMUGIX-004 1. Inspection of parts When removed, each part should be carefully inspected for malfunctioning, deformation, damage, and other problems. 2. Arrangement of parts All disassembled parts should be carefully arranged for reassembly. Be sure to separate or otherwise identify the parts to be replaced from those that will be reused. 3. Cleaning parts for reuse All parts to be reused should be carefully and thoroughly cleaned in the appropriate method. REASSEMBLY Standard values, such as torques and certain adjustments must be strictly observed in the reassembly of all parts. Refer to STANDARD BOLT AND NUT TIGHTENING TORQUE in Section TD for tightening torques not mentioned in the main text. If removed, these parts should be replaced with new ones: 1. Oil seals 2. Gaskets 3. O-rings 4. Lock washers 5. Cotter pins 6. Nylon nuts Depending on location: 1. Sealant should be applied to gaskets. 2. Oil should be applied to the moving components of parts. 3.
