Repair Manual\n\n(993)  \nVolume l:GeneralEngine  \n## Preface\n\nStructure  \nThe \"Technical Literture\"for the \"911 Carrera(993)\"model is basicaily structured as before,  \ni.e.the structure follows the familiar repair groups.  \nA new feature is that the structure includes the main groups O to 9 and the main group D  \n\n| 0   | Complete vehicle -General   |\n| --- | --- |\n| 1   | Engine   |\n| 2   | Fuel,exhaust,engine electrical system   |\n| 3   | Transmission   |\n| 4   | Chassis   |\n| 5   | Body   |\n| 6   | Body equipment,outside   |\n| 7   | Body equipment,interior   |\n| 8   | Air conditioning   |\n| 9   | Electrical system   |\n| D   | Diagnosis   |\n\nMain groups:  \nLayout  \nThe layout in the below items remains unchanged throughout the repair manual  \n1.Table of tightening torques  \n2.Special tools required  \n3.Exploded views  \n4.Legends for the exploded views  \n5.Assembly notes /use of special tools  \nAs a new feature,however,the former item 6(Repair group diagnosis)is no longer filed in thevolume corresponding to the respective repair group.The Diagnosis test plans/diagnosis proce-dures have been combined in a separate Diagnosis volume broken down according to the maingroups O to 9.  \nAnother new feature is that the contents of the \"Service Information Technik\"are indicated in theRepair Manual.This brochure concentrates on a description of the design and function of com-ponents and of the new features introduced for a particular modei year.  \nService Number  \nAll major repair procedures and repair descriptions are identified by a two-or four-digit ServiceNumber completed by two additional digits to identify the work that corresponds to the first sixdigits of the working position number in the Working Times and Damage Catalog.  \n303737 Dismantling and assembling clutch control shaft  \nExample:  \n30  37  37  50(full working position number)  \nExplanation:  \nRepair group  \nhere:Clutch,control

activity  \n3037Service number in Service Information,consisting of repair group and component designation  \n## Goal\n\nThe introduction of a service number in the \"technical literature\"is intended to facilitate stand-ardization and positive identification to allow direct cross-referencing among the various documents.This is of particular importance with regard to the use of electronic media.  \n## Structure of the Repair Manual\n\nThis Repair Manual describes all the important operations that require special instructions to ensureproper completion.This manual is an essential source of information for the shop foreman and theshop mechanics as the information in this manual must be observed at all times to keep the vehiclein safe and roadworthy condition.The basic safety rules of course also apply without exception to allrepairs on motor vehicles.  \n## Breakdown of the Repair Manual\n\n1.Overview of repair groups  \n2.Registration sheet for supplements  \n3.List of contents  \n4.Technical data  \n5.Repair groups  \n## Breakdown of the repair groups\n\n1.Table of tightening torques  \n2.Special tools required  \n3.Exploded views  \n4.Legends for the exploded views  \n5.Assembly notes /use of special tools  \n6.Diagnosis for repair groups  \nThe Repair Manual will be updated regularly with supplements which must be filed immediately tomaintain the usefulness of the manual.Appropriate entries must be made in the registration sheet toprove that the manual is complete.  \nThe contents of the Repair Manual will be supplemented by Technical information Bulletins whichwill be integrated into the manual from time to time.  \nDesciptions of design and function can be found in the service training
