Installation

PERFORMANCE ORDER

Before installation check coupling, address to the Section Removal, installation and coupling check. Clear shlitsevy connection of primary shaft and slightly grease with AUDI-G000100 MoS 2 greasing. The conducted disk of coupling should come easily on primary shaft of a check point. Surpluses of greasing clean. Clear all carving openings in which being self-stopped bolts, by a tap from the hermetic remains are rolled. Being self-stopped bolts and nuts surely replace with the new. Check wear of the bearing of switching off of coupling, if necessary, replace. If on the plastic bearing there are flutes more deeply than 0.5 mm, it is necessary to replace the bearing. Grease an adjacent surface of a pusher at the lever of the bearing of switching off of coupling with copper greasing, for example, «Z381 351 TE». Check, whether aligning plugs for centering of connection of an engine/check point in the block of cylinders stand still, if necessary, insert. Watch the correct provision of an intermediate plate at the engine if that is available. Enter horizontally a check point into coupling. If at installation 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 the Section Removal and starter installation. Screw the bottom bolts (And) for engine fastening with a check point and (In) for starter fastening. Lower the engine/check point block. Tighten the top bolts of fastening of an engine/check point the established moment. Fix a tunnel cross-piece to a support of a check point (1). Fix a tunnel cross-piece 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 draft of gear shifting. Fix it the moment 20Нм. Establish pushing bar and fix it the moment 40Нм. Establish power shafts and a guard of shaft, address to the Section Removal and installation of a power shaft. Join all earlier disunited sockets. When laying electric connections watch that all collars which removed or have been cut off at dismantle, were established on the former places. Establish the heat-shielding screen of an exhaust pipe. Establish a reception pipe and establish release system, address to the Section Removal and installation of system of release. Replacement of the central, additional exhaust silencer, trailer pipe. Check adjustment of a drive of gear shifting, address to the Section Adjustment of a drive of gear shifting. Check oil level in a check point, address to the Section Check of level of oil in a manual check point. Attach the negative (-) a cable of the storage battery.
