t  Tube -VW 418 A-

t  Oil seal extractor -T40188-

Procedure l  Gearbox must be removed and secured to engine/gearbox support in horizontal position → Chapter. –  Mark position of gearbox selector lever -A- relative to selector shaft with a waterproof pen.   Note The marking is to ensure that installation is performed correctly. –  Remove bolt -B- completely and lift off gearbox selector lever -A-.

Caution Risk of damage to selector shaft (shown here from rear side with hydraulic control unit removed). t  The selector shaft must not be pressed into or pulled out of the gearbox. t  The shifting cam -1- on the selector shaft will break off if an upward or downward force is applied to the selector shaft. t  The gearbox must be renewed if the shifting cam is damaged.

–  Screw nut -T40188/1- onto puller -T40188/2-. –  Slide puller -T40188/2- over selector shaft. –  At the same time, press puller -T40188/2- firmly into oil seal -A- in direction of -arrow 1- and screw in -arrow 2-.   Note t  The nut -T40188/1- was screwed onto the puller -T40188/2- so that greater hand pressure can be applied in the direction of -arrow 1-. t  The puller -T40188/2- cuts into the oil seal -A- when turned. t  Ensure that sealing surfaces on gearbox and selector shaft are not damaged. l  Puller -T40188/2- must be seated very firmly in the oil seal. If necessary, press in and turn puller -T40188/2- repeatedly.

–  Set up cross member -T40188- and use screw feet at side to align horizontally. l  Cross member -T40188- must be aligned so that nut -T40188/1- can make flat contact. l  Distance -X- (approx. 8 mm) between lower edge of cross member and puller -T40188/2- must be maintained. If necessary, insert washers as spacers between gearbox and screw feet.   Note The specified distance must be maintained so that the oil seal can be pulled up towards the cross member. The puller -T40188/2- will be damaged if it makes contact with the cross member before the oil seal has been removed completely. –  Screw on nut -T40188/1- and pull out oil seal for selector shaft -A-. –  Clean opening and vacuum out swarf.

–  Lightly lubricate outer circumference and sealing lip of new oil seal with ATF. –  Slip new oil seal over selector shaft and press in. –  Use tube -VW 418 A- to drive home oil seal.

–  Fit gearbox selector lever -A- onto selector shaft in line with marking and tighten bolt -B-. Tightening torque for bolt → Chapter „Exploded view - front final drive and oil seals“
