16. Place the clutch hub into the attaching flange and then fit
alternately 5 steel discs and 4 friction discs in.
17. Position the pressure ring onto the disc pack so that the
steel disc lugs fit inside the grooves on the ring. Also the loose
locking pieces must engage with grooves on the pressure
ring.
Important! 8200---8750: From ser. no. 668103 incl, the pres-
sure plate has six drillings for the springs. Before fitting the
pressure plate, fasten the spring in their drillings with a little
grease, so that they are kept in place during fitting the pres-
sure plate.
18. Fit the rearmost ball bearing against the hub (use ETV 894
030, if needed). Support e.g with two screwdrivers (at arrows)
the planetary gear front clutch disc (uppermost disc in picture
above), so that it does not drop.
19. Place the cup springs with concave sides against each
other between the planetary gear and the revers e shuttle.
20. Lift the planetary gear into placeand turnit sothat thepres-
sure oil bore together with its small o---ring comes at the pipe
connector on the reverse shuttle housing.
NOTE! Rotate the planetary gear so that the planets do not
prevent tightening of the planetary gear attaching bolts.
23 Nm (8.8)
35 Nm (10.9)
21. Raise the cup springs into place using a screwdriver and
tighten the planetary gear attaching bolts progressively to a
torque of 23 Nm (8.8), 35 Nm (10.9). Apply Loctite 243 to the
threads of the bolts. Tightening order, see pages 440/15.
Note! Tightentheboltsinordersothatwhenonebolt
becomes stiff to turn, move to the adjacent bolt until the plan-
etary gear attaching flange is tightly against its location on the
reverse shuttle front face. Never use force.
22. After fitting, pump up pressure of 1,7---2,0 MPa into the
clutch through the pipe connector. If the clutch does not dis-
engage, the clutch foremost steel disc can be wrongly posi-
tioned.In this case the clutchshouldbe assembled anew.The
connec tor has thread 9/16 JIC 37˚. The reverse shuttle hous-
ing has thread 14 x 1,5 mm.
23. Place the foremost and middle sun gear into the clutch
drum inside the gear housing fully home.
23 Nm
24. Grease the large o---ring of the housing and place the
o---ring into its groove. Push the housing into place and
tighten its four attaching bolts to 23 Nm.
25. Connect the pressure oil pipes to the gear housing.
Assemble the tractor frame according to instr. 441 2B.
26. Let the engine run for a while with the clutch pedal
depressed for proper lubrication. Test---run the tractor and
ensure that the quick---shift gear functions correctly.
