3. Maintenance
Ball coupling, hitch head
x To reduce the wear and tear on the ball coupling and towbar,
lubricate the contact surfaces with multipurpose grease at regular
intervals depending on the deployment conditions and after
cleaning with high-pressure washers.
x Lubricate the contact surfaces at the lubrication point on the hitch
head or via the central lubrication system. If there is no lubrication
point on the hitch head, the lubrication nipple order no. 65018 must
be fitted to the underside of the ball and used for lubrication.
x When the ball wears below 78.5 mm, it must be replaced. Only
replace the ball twice at the most, then fit a new ball coupling.
Repairs may only be carried out by a qualified workshop!
Works steps to replace the ball:
– Remove the slotted nut.
– Press out the ball from below – Insert a new ball.
– Screw on the slotted nut: tightening torque 160 to 180 Nm.
– Secure thread with metal adhesive (Loctite).
x The vertical play of the connected hitch head may not exceed 7mm.
When the wear limit is reached, the corresponding parts (ball, latch
and hitch head) must be replaced.
x At the latch with the adjustment screw (E) the vertical play for a
hitched hitch head can be limited to a minimum of 0.5 mm:
– Release the locking nut.
– Hold the bolt (2) with gentle pressure on the upper side of the
hitch head.
