PTO adjustment
The distance “A” (see picture
Ж
-6) be-
tween an upper point of the cylinder rod
head (8) and hydrocylinder head (7) is an
external indication of the wear factor of the
PTO brakes bands’ lining and of PTO ad-
justment necessity.
If PTO is adjusted and not worn
out, the
distance “A” should be as follows:
•
64
±
2 mm (PTO is engaged); and
•
41
±
2 mm (PTO is disengaged).
If the distance “
А
” is more than 80 mm
(PTO is engaged) or less than 32 mm
(PTO is disengaged
), or if PTO is slipping,
adjust a backlash in the band brakes.
ATTENTION!
1. Before starting PTO adjustment
,
set
“an independent/synchronized PTO”
modes shifter to a middle (neutral)
position.
2. Start the engine and do all PTO ad-
justments only at a running engine. A
parking brake is to be preliminary ap-
plied as well as the rear wheels are to
be blocked by wedges fore and aft.
