Chronology :
January 28th 2023: Start use of non self locking nut on 8 positions on front axle in production due to health and
safety issue with mounting the existing nuts.
October 9th 2023: we received report from our distributor in UK that on a number of non-highway vehicles
the nuts were found loose.
October 10th 2023: a meeting was held to start internal investigation.
October 17th 2023: decision was taken to go back to self locking nuts, and on locations where self locking nut
is not possible a thread locker (Loctite 243) must be applied. All used torques and documentation have been
reviewed. Also the containment action to re-work all machines that are produced but not yet delivered is
started.
November 6th 2023: it is clear which machines are modified before delivery in the containment action, and
which vehicles were not. Start with preparing the Modification Bulletin.

Front axle mounting check
YTxx3, DT
From the end of January 2023 until October 2023 flange nuts ( non self locking) were used to mount the front axle to the
YTxx3 and DTxx3. This flange nut t26031374 can be recognized by a spanner size 32 mm.
For some unknown reason we have seen a few cases were the nuts did unwind themselves from the bolts.
Therefore we changed our production method for the YTxx3 as follows:
Use 4 times a non self locking nut with Loctite 243 on the rear side of the axle where space is limited, and 4 self locking nuts
for the remaining positions.
For information: The non self locking nut has spanner size 32 and the self locking nut t26041075 has spanner size 36.
We changed our production method for the DTxx3 as follows:
Use 8 times self locking nut t26041075 with spanner size 36.
We reworked as much vehicles as possible that we had not shipped. For all vehicle with the 8 non self locking bolts that were
delivered before we discovered this issue or before we could perform our rework action please see the recommended action
below.
Documentation group of the steering system 90-02-01-444 RHD or 90-02-01-536 LHD was not updated with the correct nuts.
The correct nuts are displayed in the group of the front axle mounting 60-01-02-158. The fact that the wrong nut was
displayed in group 90-02-01-444/536 might have been confusing to some.
As stipulated in the Terberg Maintenance Manual TD1215 the correct mounting and tightening of bolts on the front and rear
axles should be checked on the first, periodic and annual maintenance intervals. According to TD1215 the first interval
should be performed after the first 100 operating hours of the vehicle.
