9 3 Gearboxes Gearbox 02T New! Selecting and shifting based on the standard shift pattern 5 R SP32_06 SP32_112 The gearbox is a new development and is designed for transmitting engine torques of up to 200 Nm. Gearbox designation 02TA for petrol engines of 55 and 74 kw 02TB for diesel engine of 47 kw Distinction only in the internal ratio. Technical highlights 5-speed manual gearbox Hydraulic clutch control, design based on gearbox 002 Manual gearbox and final drive form a single constructional unit; new materials used for achieving weight reductions Needle bearings for sliding gears in order to reduce the internal friction Double synchromesh for 1st and 2nd gear (improved shift quality) Internal shift mechanism (shift forks) is designed as a shift arm mechanism; shift shaft enters the gearbox from the top Transmission oil filled for entire service life; no oil change necessary Oil inspection plug in area of the differential 20

10 New! The speedometer drive The speedometer is driven without any mechanical intermediate stages. No speedometer gear, no speedometer shaft. The information regarding the road speed of the vehicle is tapped directly at the differential housing by the speedometer sender G22. The differential housing is provided with reference marks for this purpose. Speedometer sender G22 The speedometer sensor takes the place of the speedometer shaft at the gearbox. Reference marks at differential housing SP32_23 The information is passed electrically in the form of pulses from the speedometer sender to the control unit in the dash panel insert. It is processed there for indicating the vehicle speed and the distance. Advantage: Optimal accuracy of indications and smooth needle readings. You can find further information on the gearbox in SSP 37. SP32_101 21

11 Gearboxes Gearbox 002 Gearbox designation 002H for 1.0-ltr./37 kw engines 002G for 1.4-ltr./50 kw engines The difference is in the inner transmission ratio. The gearbox is a further development of the gearbox described in SSP 27. Highlights of the technical modifications The shift movements are transmitted into the gearbox from above. SP32_05 At the top on the gearbox there is a shift cover which houses the shift shaft for the internal shift mechanism and the relay of the shift movement. R SP32_112 The gears are shifted by means of shift arms. The shift pattern is matched to the standard pattern. The external shift mechanism has been simplified. It has a similar operating principle to the cable shift mechanism in the OCTAVIA. A locking pin is provided at the shift cover with which it is possible to fix the shift shaft in a predefined position. This greatly simplifies the adjustment of the cable shift mechanism. Shift cover Shift shaft Selecting Shifting SP32_25 22

12 Shift mechanism The shift movement is transmitted from the shift lever into the gearbox by means of two cables in all the gearbox versions. The principle used for relaying the shift movements from the hand shift lever to the gearbox shift lever is the same as that employed on the OCTAVIA R 4 2 SP32_26 Selecting Shifting SP32_27 Engine/gearbox mounting The engine/gearbox mounting is similar to the pendulum mounting (3-point mounting) familiar from the OCTAVIA. The engine and gearbox mounts are positioned around the pivot axis of the power plant. The pendulum support absorbs tensile and compressive forces. The bearing mounting brackets are matched to the particular engine type. Engine mount with mounting bracket Gearbox mount with mounting bracket SP32_28 Pendulum support 23

13 Fuel System Fuel tank Activated charcoal filter Expansion tank (operating vent, refuelling vent) Fuel filler neck Fuel delivery unit Fuel filter with pressure regulator SP32_30 The fuel tank is made of plastic. It holds approx. 45 litres. Important! Fuel tank, filler neck and 2 expansion tanks (operating vent, refuelling vent) are a single unit. They cannot be separated. The fuel delivery unit is located in the fuel tank. The following components are located directly at the fuel tank the fuel filter the activated charcoal filter. Both are connected to the fuel tank by flexible plastic lines. The fuel pressure regulator is an integral part of the fuel filter. It is no longer positioned at the fuel rail of the engine. 24

14 Fuel tank vent system Vent valve Unleaded petrol flap Vent line Refuelling nozzle Cap Gravity valve Refuelling vent tank Operating vent tank Feed line, black Return-flow line, blue Fuel filter Activated charcoal filter M to engine to engine SP32_45 In contrast to the predecessor version, the activated charcoal filter is not located in the left rear wheelhouse, but behind the wheelhouse liner behind the right rear wing. Venting when refuelling When the cap is removed, the vent valve automatically shuts off the vent line to the operating vent tank. Fuel vapours from the fuel tank thus do not escape to atmosphere during refuelling. The unleaded petrol flap is opened by the refuelling nozzle. The air from the fuel tank is passed to the refuelling vent tank during refuelling and from there to the fuel filler neck. Venting when driving The unleaded petrol flap shuts off the filler neck by means of the spring tension. The cap on the filler neck pushes open the vent valve. Fuel vapours which form as a result of the fuel warming up, flow into the operating vent tank. These vapours pass through the opened vent valve and the filler neck, which is sealed off to atmosphere, through the gravity valve to activated charcoal filter where they are bonded. 25

15 Fuel System Fuel filter with pressure regulating valve New! Fuel filter and pressure regulating valve are a combined component. This is positioned directly at the fuel tank and is divided into a spring chamber and a filter chamber. The fuel pump pumps fuel into the filter chamber, the pressure regulating valve maintains the system pressure of 3 bar (0.3 MPa), which is effective in the fuel rail at the injectors. SP32_31 The fuel is metered to the filter by means of an orifice plate in order to maintain the pressure. If the pressure rises above 3 bar (0.3 MPa), the regulating valve to the spring chamber opens. Excessive pumped fuel flows back along the shortest path unfiltered through the regulating valve into the fuel tank without having to take the long way round through the engine compartment. Spring chamber Return flow to fuel tank Regulating valve Filter chamber Feed from fuel pump to engine SP32_32 Advantages: This makes it possible to eliminate the returnflow line from the engine to the fuel tank. The fuel which flows back is warmed up less, the temperature in the fuel tank remains lower and the quantity of evaporating fuel is reduced. The fuel flowing back is not filtered. The service life of the filter is extended. Note: The fuel injection system in engine has been modified accordingly. The engine now has a fuel rail through which the fuel does not flow. 26
