Remove a reception pipe (3) with клеммной plugs (2), address to the Part of System of release and decrease in toxicity of the fulfilled gases. turbocharger. Remove the heat-shielding screen (4) over release system. Turn out the bottom connecting bolts the engine/kpp (arrows on an accompanying illustration). Disconnect on flanges both power shafts and adhere them on a wire, address to Section Removal and power shaft installation. Watch that at отворачивании not to damage a sheeting of power shafts. Remove a starter, thus a cable do not disconnect from a starter. Fix a starter on a wire to a body. On HUNDRED check points it is fixed and supported by lift V.A.G. If the specified lift available is not present, bring under a check point the garage lift with a wide wooden lining and slightly raise a check point. Turn out at first bolts (2) and then bolts (3) on a tunnel cross-beam. Turn out both nuts (4), remove a tunnel cross-beam.

Installation

PERFORMANCE ORDER

Before installation check up coupling, address to Section Removal, installation and coupling check. Clear шлицевое connection of a primary shaft and slightly grease with greasing MoS 2 AUDI-G000100. The conducted disk of coupling should come easily on a primary shaft of a check point. Surpluses of greasing clean. Clear all carving apertures in which self-stopped bolts, by a tap from the hermetic rests are rolled. Self-stopped bolts and nuts necessarily replace with the new. Check up deterioration of the bearing of deenergizing of coupling, if necessary, replace. If on the plastic bearing there are flutes more deeply 0.5 mm, it is necessary to replace the bearing. Grease an adjoining surface of a pusher at the lever of the bearing of deenergizing of coupling with copper greasing, for example, «Z381 351 TE». Check up, whether aligning plugs for centering of connection the engine/kpp in the block of cylinders stand still, if necessary, insert. Watch correct position of an intermediate plate at the engine if that is available. Enter horizontally a check point into coupling. If at installation the primary shaft of a check point does not enter into a conducted disk, turn a hand a shaft for a flange. Establish the working cylinder of a drive of coupling with the holder. By means of mount enter the cylinder so that it is possible to insert a fastening bolt easily. Tighten a bolt the moment 25Нм. Establish into place a starter, address to Section Removal and starter installation. Screw the bottom bolts () for fastening of the engine from a check point and () for starter fastening. Lower the block the engine/kpp. Tighten the top bolts of fastening the engine/kpp the established moment. Fix a tunnel cross-beam to a support of a check point (1). Fix a tunnel cross-beam to a body. Screw at first a bolt (2) then a bolt (3). Tighten from below 3 bolts of fastening of the engine to a check point the moment 45Нм. Establish into place draught of a gear change. Fix its moment 20Нм. Establish pushing bar and fix its moment 40Нм. Establish power shafts and a guard of shaft, address to Section Removal and power shaft installation. Join all earlier disunited sockets. At a lining of electric connections watch that all collars which removed or have been cut off at dismantle, have been established on the former places. Establish the heat-shielding screen of an exhaust pipe. Establish a reception pipe and establish release system, address to Section Removal and installation of system of release. Replacement of the central, additional muffler, a trailer pipe. Check up adjustment of a drive of a gear change, address to Section Adjustment of a drive of a gear change. Check up oil level in a check point, address to Section Check of level of oil in a manual check point. Attach negative (-) a cable of the storage battery.
