Maintenance and operating instructions ZAF-2
Removing the overrun damper and
the pull rod
Ensure trailer is securely chocked.
Disconnect brake linkage.
To facilitate handling, we recommend
unscrewing the overrun hitch from the
chassis and securing it in a vice.
The ball hitch or towing eye must be removed
in order to remove the overrun damper (see
page 13).
If the overrun hitch has a towing eye,
remove the rear bolt of the pull rod.
Push in the pull rod.
Unscrew the locknut from the bolt and pull
out.
Pull the overrun damper out of the pull rod.
Check the overrun damper for wear and
leaks and replace it if necessary.
To change the pull rod, it is necessary to
remove accessories (e.g. jockey wheel
holder) that are installed in the rear part of
the overrun hitch!
Pull the pull rod and bump stop (corrugated
ring) backwards out of the housing.
Check the bump stop and the pull rod for
damage and wear and replace them
if necessary.

Installing the overrun damper and the
pull rod
Before installing, apply grease to the pull rod
(1) and push it from the rear into the housing
with the tightening damper until the slot in the
pull rod lines up with the hole in the housing.
Insert the threaded bolt for locking, push the
pull rod backwards and pull the threaded bolt
out again.
Guide the overrun damper into the pull rod
with the pressure body foremost until the rear
overrun damper eye lines up with the slot in
the pull rod and the hole in the housing.
Grease the pull rod via the grease nipple.
Install the threaded bolt, screw on a new
locknut and tighten to a specified tightening
torque of 30 – 40 Nm.
Pull the pull rod forwards out of the housing.
Fit the bellows.
Overrun hitch with towing eye:
Use a screwdriver or a drift to line up the
rear hole in the pull rod with the bush in the
overrun damper.
Push through the bolt and install a new
locknut. Tighten the locknut to the specified
tightening torque of 30 – 40 Nm.
