Repairing the Automatic Trailer Hitch

Repairing the Automatic Trailer Hitch

Two-Lever Operation

Open the trailer hitch, pull the bowden cable out of cover (6) and disengage the bowden cable eye from cable lever (24).
Close the hitch again using release lever (8). Take the hitch out of the guide rails.

Remove spring pin (25), and pull off cable lever (24) and return spring (23).

Remove cover (6). From the inside, knock out closure cap (37). Lift up control lever (18) and knock spring pin (22) out
from the outside through the opening for closure cap (37) - do not approach it from above, otherwise the pin will stick. Pull
out the control lever.

Hitch pin (4) is held loosely by release lever (8). Press the hitch pin all the way down and take out locking catch (21) and
the shim (if equipped). Take out the hitch pin from above. Indicator pin (14) and its spring will fall out through the hitch pin
bore. Remove cotter pin (12) and the washer. Pull out locking lever (10) and take out release lever (8) from above. Spring
(9) will fall out.

Clean the components and apply multi-purpose grease.

From below, knock out lower bushing (3). Insert a new bushing and secure it from below to the bore of the hitch body by
peening.

Re-install all the components in reverse order.

To prevent indicator pin (14) from falling to the inside when hitch pin (4) is being installed, the indicator pin must be held
securely with pliers from the outside. Lift the hitch pin slightly to insert locking catch (21). To do this, press locking lever
(10). The lower finger of the locking lever must engage in the shaped recess in the hitch pin. If required, center the locking
lever in relation to the hitch pin by inserting shim (20). When the bores in the control lever and the locking catch are
aligned, knock in a new spring pin (22) from above.

After assembly, apply more grease to the hitch.

The axial torque of the hitch can be increased at adjusting screw (28).

Before returning the tractor to operation, check that the hitch closes properly. Indicator pin (14)
must no longer protrude from its bore; if it does protrude, the hitch pin has not reached its lowest
position and is NOT double-locked.

Adjustment Unit Repair (Parts 29 to 36)

Remove the four cap screws (36) from end plate (35). Turn the end plate in the direction that torsion spring (34) turns. End
plate (35), bearing pin (30), torsion spring (34), cylindrical pins (32), cam plate (33), locking bolts (31) and bearing plate
(29) can all be removed. Clean and check all components. Apply grease to new parts and install in reverse order. Insert
end of torsion spring into the shaped recess in the end plate. Turn the end plate against the pressure of the torsion spring
and at the same time slide the bearing bore (in the end plate) over the spigot on the end of bearing pin (30). Insert and
tighten cap screws.

Adjustment Unit Functional Check

Turn the handle on cam plate (33) up and push it to the left. Locking bolts (31) move inward. When the handle is released,
the cam plate returns to its initial position. The locking bolts are extended again. Because the handle and locking cam turn
back automatically, the cam plate cannot be displaced unintentionally. In the locked position, the handle on the cam plate
can be moved by only about 4 mm (0.16 in.) to the left.

Close the hitch and take the hitch out of the guide rails.

Clean all parts and coat them lightly with grease.

Changing the Hitch Pin

Remove cover (5). Open the hitch with control lever (13). From the outside, use pliers to hold indicator pin (8) securely,
preventing the indicator pin and spring (7) from falling into the hitch. Turn locking catch (16) upward until hitch pin (4) can
be removed from above. Hold the locking catch securely and insert the new pin. Guide the lug on the locking catch into
the shaped recess in the hitch pin, and then release. Remove the pliers from the indicator pin. Put on cover (5) and tighten

hex. socket screws (6).

Before returning the tractor to operation, check that the mechanism functions automatically. Open the hitch with control
lever (13). Indicator pin (8) must not protrude out of the sleeve!

Vertical play at the hitch pin is approx. 2 mm (0.08 in.).

Changing the Lower Bushing

From below, knock out the lower bushing (3). Insert a new bushing and secure it from below to the bore of the hitch body
by peening.

Disassembling the Automatic Mechanism

Knock out spring pin (25) and pull off cable lever (24) and return spring (23). Remove cover (5). Remove snap ring (26)
and slide out shaft (27). Take out the pin-raising lever (29), torsion spring (30) and shims (28; if equipped). Note the
position of the shims. Knock out spring pin (22) from above. Pull out control lever (13) and take out parts 14 to 21. Take
out hitch pin (4); indicator pin (8) and spring (7) fall into the hitch.

Installing the Automatic Mechanism

Install the parts in reverse order. Check that detent pin (19) operates smoothly at release lever (15). Install the release
lever, locking catch (16), control plate (20) and spring (14) on an assembly tool (17.8 mm dia., 46 mm length), and insert.
Re-install shim(s) (17) as they were before. Insert shaft of control lever (13) through the bores of the parts centered on the
assembly tool, and include shim(s) (17). Make sure that control plate (20) is in contact with the flattened surface of the
hitch body. The lug on which spring (21) is inserted must be uppermost. Align the bore of locking catch (16) with that of
control lever (13), and knock in a new spring pin from above. Insert spring (21) between control plate (20) and the spring
retainer on the hitch body. Make sure that the spring is seated securely and the control plate moves smoothly. From the
inside, insert indicator pin (8) and spring (7), and hold them securely from the outside with a pair of pliers. Insert hitch pin
(4) from above, and remove the pliers. Insert the pin-raising lever (29) and torsion spring (30). Insert shaft (27) and secure
it with snap ring (26). To do this, push down the locking catch against the pressure of the spring until the bore in the hitch
body is aligned with the bore in the locking catch. Install shim(s) (28) as they were before.

Automatic Mechanism Functional Check

Use a suitable tool (NOT your hand!) to hold release lever (15) in the recess in the base of the jaws and at the same time
open the hitch by means of the control lever. It must be possible to push the control lever to its final position (roughly
vertical), and to engage it positively. Let go the release lever again. The lever must move to the “stand-by” position, where
it can be heard to lock into position. Close the hitch by pushing back the release lever (NOT by hand!). Indicator pin (8)
must not protrude out of the sleeve! To make sure the hitch is operating safely, repeat the hitching procedure.

Install cover (5) and tighten hex. socket screws (6). Put the cable lever (24) and return spring (23) on the shaft of the
control lever, and knock in spring pin (25). Check that the cable lever moves smoothly.

NOTE:

Shims (17) and (28) are required to center the components.
