the tension pin (A) and by pushing the gear axles to the left

Assembling
Emptying valve
11. If you have removed the piston, push it down into its
location. Place the spiral spring support plate onto the pis-
ton and fit the small spiral springs into their borings (pic-
ture).
Important! Position the piston into its location so that the
emptying valve comes upwards (when the shuttle is fitted in
tractor).
Note! Ensure, that a spring is not at the emptying valve (a
spring can partly block a hole). Change all springs in con-
nection with repair work.
The emptying valve of the R---clutch has been removed
with effect from ser. no. K41107 ( AC 5.2, HiTech 2.0).
12. Fit the ball bearing (picture).
13. Fit t he hub (picture). Dip the frictio n discs in oil a littlew-
hile before fitting.
14. Fit by turns new friction and steel discs and s pr ing
rings. A steel disc first against the piston springs and
uppermost a friction disc (9 pcs steel discs, 9 pcs friction
discs and 9 pcs spring rings). The s pring rings are placed
into the outer circumference o f the friction discs.
Note! The discs and the spring rings are the same as in the
clutch for the forward driving and a number of the discs is
also the same.
Note! Dip all friction discs in oil before fitting.
