LEVER TRAVEL:
Mod: ZF 5 M - 10 M- 12 M - 15 M - 15 MA
- 15 MIV - 25 M - 25 MA - 30 M.
Minimum travel of gear shift lever (N-
A=N-B) must be 35 mm (1.3/8") for
outer pivot point and 30 mm (1.3/16")
for inner pivot point.

22 ± 1 Nm (17 lbf ft)
2) Minimum lever travel for control cable
3) Do not open cover
4) Oil drain plug
Driving torque: Ma = 22 Nm (16 lb-ft).
LEVER TRAVEL:
Mod: ZF 4-1 M
Travel of gear shift lever (N-A=N-B)
must be 38,5±1,5 mm (1.52 in ± 0.06
in) for outer pivot point and 33,5±1,5
mm, (1.32 in ± 0.06 in) for inner pivot
point, from neutral position. When the
lever pass over the angle of 10°-12°, it
starts to move outside perpendiculary
and stops when the travel is completed
(angle of 40°).

1) Clamping screw torque
22 ± 1 Nm (17 lbf ft)
2) Do not unscrew the nut
3) Do not open cover
LEVER POSITION: In neutral position
perpendicular to control rod or cable.
Gear shift lever can be fixed in any
position by means of clamping screw.
Minimum distance between gear shift
lever and cover 0.5 mm (0.02"). Open-
ing or loosening of cover requires re-
newed adjustment (by specialized per-
sonnel only).

1) Oil dipstick and filler screw, 17 mm
Driving torque: Ma = 20 Nm (15 lb-ft).
2) Control lever clearance min 0.5 mm
INSPECTIONS: Frequently check the
position of the lever to make sure that
everything operates correctly.

Operating Manual ZF 4-1 M / ZF 30 M
6.1 Maintenance
6.1.1 FLUID LEVEL CHECK
WARNING
Do not work on the transmission
when being towed, or anchoring in
a river because the propeller may
rotate.
DESCRIPTION OF THE DIPSTICK
(Fig. 11):
1) Housing surface
2) Dipstick
3) ATF level
4) ATF
5) Retention washer
Transmission f luid level may be
checked in cold or hot condition.
NOTE: Always check the oil level be-
fore operating the reverser. Proceed as
described below.
- Loosen fluid dipstick (figure 11) by
turning the grip counterclockwise.
- W ipe dipstick with a clean and
dustfree cloth.
- Insert dipstick do not screw in (3-4 fig-
ure 11). Remove dipstick and check
fluid level: Fluid level has to be between
minimum and maximum marks.
- Insert the dipstick and lock it by turn-
ing the grip clockwise.
CAUTION
According to the type and arrange-
ment of the cooler and pipelines a
certain amount of oil will collect af-
ter stopping the engine and will flow
back into the transmission after a
longer rest period. This may cause
the oil level in the transmission to
exceed the max. mark. Do not re-
move off the surplus oil but proceed
according to steps.
- Let engine run at idle speed with shift-
ing lever in neutral position until fluid
cooler and all pipelines are filled with
fluid.
- Switch off engine and check fluid
level within a short time. If necessary,
top fluid level off to the dipstick mark.
The fluid level on the dipstick (figure
11) should be between the min. and
max. marks.The fluid level must be
checked again after a short driving
period.
6.1.2 FLUID CHANGE
CAUTION
The first change must be performed
after 25 hours of operation. All sub-
sequent fluid changes to be made
after every 300 hours of operation
or once in a year (according to the
term which is reached earlier).
CAUTION
Used lubricant must be treated as
special waste that pollutes the en-
vironment: it must therefore de dis-
posed of in accordance with its par-
ticular structure.
6.1.3 DRAINING
TRANSMISSION FLUID
Remove the plug (1 Fig. 12) and allow
the oil to drain through the hole in the
lower part of the housing.
6.1.4 FILLING UP WITH
TRANSMISSION FLUID
Fill with ATF oil for automatic gear-
boxes according to the indicated quan-
tities. Add the quantity considered nec-
essary for filling the heat exchanger
and relative connection pipes.
