GEAR HOUSING – INTERMEDIATE SHAFT
510 22 11-01
IMPORTANT
When refitting, oil the spring
washers and friction washer
with gearbox oil.
This is important in ob -
taining the correct slip torque
when adjusting the slip clutch.
–
Europe: 17 Nm
USA: 15 Nm, 11 lbf·ft
Spring washers
The spring washers provide the brake
force to the slip clutch when the nut has
been fitted and tightened with the correct
torque.
It is particularly important for this
function that the washers are correctly
turned and that they are intact.
Removing spring washers
Lift up the three spring washers and the
flat washer under these.
Removing friction washer
Remove the friction washer from the
gear wheel.
Replace the washer if damaged or
where its functionality is obviously
impaired.
Lift off gear wheel
Check the condition of the gear wheel
and that the centre bushing does not
have too much play with the shaft.
The bushing has a light force fitting to
the gear wheel.
Removing friction washer
Remove the friction washer from the
gear wheel.
Replace the washer if damaged or
where its functionality is obviously
impaired.
Rem. For practical work, lift the gear
wheel up from the shaft and turn over to
empty the washers.
Adjusting the slip clutch
Place the intermediate shaft's helical
drive in the vice with soft fibre jaws.
First tighten the nut to the mechanical
stop. Then go back 45°. Now the clutch
should slip at a minimum torque of 17
Nm (15 Nm or 11 lbf/ft in USA). If not,
+
replace the spring and friction washers.
These can be ordered in a complete kit.
Part No. 525 40 20-01.
If the torque is higher, adjust to the
correct figure.
