Attention
In order to avoid inadmissible leakage problems on the screws, it is mandatory to observe the
following procedure for thread sealing:
•
Always seal the screws (Item 01) located in the oil sump of the transmission! For this purpose
these are to be wetted with LOCTITE 243 around the thread contact face and only then to be
attached.
•
In order to avoid inadmissible variations among the screw clamping forces, always pretension the
screws carefully crosswise to the specified value. Tightening torque:
34 Nm Cl.3 ZF Standard
148
•
After a possible disassembly the LOCTITE residues in the threaded holes must be removed. It is
necessary to use new screws.
Mounting of the chain tensioner
1. Hang the chain tensioner (Item 03) into the requested position on the chain guideway and swivel it so
that the tensional pin (Item 09) can be hit in.

attention that the roller chain is mounted on the adjustable element (Item 04) in the correct position
and in accordance with the mounting dimensions.
5. Tension the roller chain by tightening the tensioning bolt. At a tightening torque of: 6
+1
Nm the roller
chain is tensioned correctly and the adjustment of the chain drive is correct.
6. Then fix the hexagon nut to the adjustable element and lock it respectively.
