TRUNK LID

Number	Designation		Model 170
BA88.50-P-1008-01A	Bolt, striker to tubular frame	NM	10

Check adjustment of striker (8) in relation to catch socket (7), adjust if necessary
Striker (8) should run into the catch socket (7) in the lateral direction in the middle and in the longitudinal direction at the front edge

Fig 1: Identifying Striker & Catch Socket
If required, correct longitudinal adjustment on striker (8). Adjust lateral direction on console (1)
Remove side paneling in trunk to adjust console (1)

Fig 2: Identifying Console & Catch Socket
Open emergency actuation valve (N) to relieve pressure from hydraulic system.

Fig 3: Identifying Emergency Actuation Valve
Open trunk lid and lay square tube (2) on fender in area of locks
Square tube approx.. 1500 mm long

Protect fender against damage with adhesive tape.

Fig 4: Identifying Square Tube On Fender In Area Of Locks
Measure distance (A) between square tube (2) and tubular frame (1) in middle of surface on tubular frame (1).
Loosen bolts (3) for striker (4) from tubular frame (1)
Adjust tubular frame (1) in direction of arrow, check distance (A) n and tighten bolts (3).

Fig 5: Identifying Square Tube, Tubular Frame, Bolts, Striker & Distance Measurement
Close emergency actuation valve (N) and build up pressure in hydraulic system by actuating Vario roof
Measure distance between square tube and tubular frame again.
If the distance measured is outside the permissible tolerance adjust hydraulic cylinder

Fig 6: Identifying Emergency Actuation Valve

Adjust hydraulic cylinder

Open retaining bracket (4) and pull out bolt
An O-ring is located at the outside between fork head and tubular frame
Open counternut on fork head of hydraulic cylinder and then unscrew fork head with two turns

Fig 7: Opening Retaining Bracket
Refasten hydraulic cylinder to tubular frame and lock tubular frame hydraulically.
When doing this check whether tubular frame lock engages properly. If this is not the case, correct adjustment of fork head in small increments (11/21 turn) until locking is ensured
Measure (A) distance between square tube (2) and tubular frame (1) again.
