ASSEMBLY OF THE MECHANISM
Make sure that the both pressure bearings are installed
in a correct position, that is, the bearing with bigger
internal diameter should be facing the cable drum (fi-
gure 21). Make sure that the position of the two clutch
engagement halves is correct (fig. 20).
1. Place one of the clutch engagement halves on the
working tble so that the handle is at 8 o’clock posi-
tion and the 3 slanted surfaces face up.
2. Grease the 3 slanted surfaces with vaseline and
place the 3 rollers on the bottom of the slanted
surfaces so that the thin ends point towards the
middle. The other clutch engagement half (without
handle) has 3 slanted surfaces on one side and
two holes drilled on the other side (fig 20). Two
studs on the back of the front plate will fit into
these holes later on when the winch is assembled.
3. Place one clutch engagement half (without the
handle) so that the halves bottom out when the
handle is at 8 o’clock position and the two holes
are at 12 o’clock and 6 o’clock (fig. 20). Be careful,
there is only one correct position! Tape the halves
together so that htey will stay together when you
mount them on the drum axle.
4. Install a protective plate. Check the clutch adjust-
ment.
