Disassembly, Assembly and Measuring of Clutch K2

Clutch K2 Exploded View:

NOTE: The number of springs is determined by weighing, for this reason up to two springs less may be installed.

Clutch Plate Sequence:

Disassembly and Assembly





1 Remove circlip (11).

Installation Note
Upon insertion push circlip along entire circumference in upward direction by means of a screwdriver.





2 Tilt outside plate carrier (1) and remove plate package.

Installation Note
Pay attention to clutch plate sequence. Assemble clutch package according to transmission model designation.





3 Place assembly device (020) on spring retainer and tension until circlip (5) is exposed. Remove circlip (5). Release assembly fixture 126 589 02 14 00 and remove.

Installation Note
Upon insertion, check circlip for correct seat.





4 Remove spring retainer (4) and compression springs (3).

Installation Note
Pay attention to number of return springs and make sure that each spring is centered by a guide lug of spring retainer.





5 Pull piston (2) out of outside plate carrier (1).

NOTE: Check O-ring between outside plate carrier and piston guide ring for leaks. For this purpose, fill some kerosene or benzine into piston guide ring. Then watch whether fluid flows off. In the event of leaks, replace outside plate carrier.

Installation Note





Check sealing rings (12 and 13) for wear or damage and replace, if required.

6 Insert sealing ring (12), making sure that the sealing ring is not twisted.
7 Insert lip sealing ring (13) into piston (2) in such a manner that the sealing lip is pointing downwards (in direction of arrow).





8 Place installation sleeve (021) on outside plate carrier (1). Lubricate installation sleeve as well as sealing rings (12 and 13) with ATF.
9 Carefully place piston (2) into outside plate carrier, while slightly rotating and pushing down piston without canting.
10 Remove Installation sleeve 126 589 02 14 00 (021).

Measuring





11 Determine clearance "A" by means of a slip gauge.

Set release clearance to 0.7 - 1.2 mm.

NOTE: Starting transmission end No. 243 517 clearance "A" is set by means of the circlip available in three sizes (2.0/2.5/3.0 mm thick). The groove for the circlip is machined to 3.2 mm. If the specified clearance "A" is not obtained with circlip (11), compensate additionally with center outside plates (such as transmission with lower end No.).
