Power steering gear, disassembling and
reassembling (TRW)
This repair is limited to replacing the sealing
rings and, if necessary, the toothed rod. Steering
gears that are damaged by an accident must be
replaced.
For a satisfactory and successful repair, the
greatest care, safety and proper tools are
required. The special tool set 3315 that is
pictured is also a part of this.

Note:
Clean hose connections and their surroundings
thoroughly before opening.
Thoroughly clean work place (workbench, vise)
before starting work if necessary place paper
towels on the working surface.
Place parts that have been removed on a clean
surface. If the repair will not be carried out
immediately, cover parts.
Do not use cloths with lint. All the replacement parts that are needed are
contained in the repair kit.
Only take replacement parts out of the package
right before installing. Use only parts in original
packaging.
