54 37... Gauge coupling lock (after removal and installation of roof module)

Special tools required:

IMPORTANT: To prevent damaging the coupling lock gauge, set the coupling lock gauge down only in the transportation crate or on the cross member.
The coupling lock gauge is a highly sensitive measuring instrument which reacts even to light impacts with distortion.
The coupling lock gauge must be checked for dimensional accuracy on a master gauge after being subjected to impact or dropped.

NOTE: The gauging of the coupling lock is required after each REMOVAL AND INSTALLATION OF THE ROOF MODULE .

Necessary preliminary tasks

ROOF MODULE must be installed.
Align BASIC GAUGE .

IMPORTANT: Tape off corners of the roof shell 1 and 3. Risk of damage when positioning gauge for coupling lock and installation work.

Gauge, coupling lock

NOTE: Coupling lock may not be screwed for adjustment work (barrel screws move freely).

Loosen screw for rubber stop (1) and move.

Insert special tool 54 0 130 in coupling lock.

Turn L-piece (2) under stop screw (3) from the coupling lock.

Adjust coupling lock as follows:

Bring stop screw (3) with adjusting screw (1) fully to the limit position (4).

Stop screw (3) from the coupling lock lies flush on the limit position (4)
Ideally, the L-piece (2) lies on the gauge

Bring barrel screws into contact with special tool 54 0 180 in conjunction with special tool 00 9 450 .

Tightening torque: 0.2 Nm (=20 cNm)

Installation note:

Observe screwing sequence of coupling lock:

See INSTALLING ROOF MODULE .

Z-direction (coupling lock to screwing plate, rollover protection system)
Y-direction (coupling lock to side panel)
X-direction (roof frame to partition wall)

Tightening torque: 54 37 22AZ .
