–  Detach bottom cover -1- from gearbox -arrow-.

–  Insert guide pin of adapter -T40058- as follows: l  The larger-diameter section -arrow 1- faces towards the engine. l  The smaller-diameter section -arrow 2- faces the adapter.

–  Remove bolt -arrow- for ATF lines.   Note

t  Observe rules for cleanliness when working on gearbox → Rep. gr.00. t  Lay a cloth under the separating point to catch escaping ATF. –  Unscrew bolts -1- and -2-, detach ATF lines from gearbox and tie up ATF lines. –  Seal off open pipes/lines and connections with clean plugs from engine bung set -VAS 6122-.

–  Counterhold crankshaft using adapter -T40058- when slackening bolts for dual-mass flywheel.   Note When performing the next step, turn the crankshaft only in the normal direction of rotation -arrow-.

–  Remove 6 bolts -arrow- for dual-mass flywheel, turning crankshaft 60° in normal direction of rotation each time.

Caution If a used belt runs in the opposite direction when it is refitted, this can cause breakage. Before removing, mark direction of rotation of poly V-belt with chalk or felt-tip pen for re-installation. –  Slacken poly V-belt by turning tensioner in clockwise direction -arrow- using socket Torx T 60 -T40087-. –  Remove poly V-belt from tensioner and release tensioner.

–  Remove bolt -2- and pivot tensioner in clockwise direction -arrow-.   Note Disregard -item 1-.
