Door beam
(hinge rotor)
Door beam pivot bearings
The door beam hinge uses two maintenance free 'top hat' section synthetic bearings, pressed into the
hinge stator bracket. Inside each bearing, is fitted a 'top hat' section steel rotor bush, clamped to the door
beam extension by an M10 cap head screw threaded into the door beam.
The door beam extension also incorporates a cheek flange which abuts against a rubber strip on the
hinge bracket to limit door opening angle. A spring steel plate fixed to the front of the hinge bracket is designed
to engage around the profiled edge of the door beam abutment flange when the door is fully open, in order to
provide a sprung restraint for the door in this position. A plastic shoe is used over the sliding surface of the
spring plate to provide for maintenance free operation, with the shoe moulding clamped between the spring
plate and chassis. To help protect the hinge mechanism from water and dirt ingress, a plastic shield is push
fitted over the retaining nuts for the spring plate.
To remove the door assembly, or for access to the door pivot components, the two M10 cap head rotor
bush retaining screws should be removed, and the door assembly withdrawn from the hinge bracket. The rotor
bushes and/or bearings may then be withdrawn from the hinge bracket. On re-assembly, note that the bearings
and bushes are assembled dry from above and below the upper and lower housings respectively, and the cap
head screws tightened to 45 Nm. Insert the rubber bungs into the bush ends to inhibit dirt ingress and corro-
sion.
