3.1.3. Removal and installation of the main cylinder of a hydraulic actuator of coupling
Merge working liquid via the union for pumping (fig. 3.6)
Unscrew a nut of fastening of the main cylinder.
Fig. 3.7. A clip of fastening of the pipeline to a transmission
Remove a clip of fastening of the pipeline to a transmission (fig. 3.7)
Check of a technical condition
Check a hose and the pipeline on existence of a rust, sinks and задиров.
Attach the pipeline to the working cylinder.
Establish the main cylinder.
Attach a pusher to a coupling pedal.
Pump over a coupling hydraulic actuator.
Remove a lock ring of the piston.
Take out a pusher assembled with the piston.
Thus watch to damaging the case and the cylinder piston.
Check after installation
Check a cylinder mirror on existence of a rust, sinks and задиров.
Check a cylinder cuff on wear or distortion existence.
Check the piston on existence of a rust, sinks go задиров.
Check purity of the pipeline.
Fig. 3.9. Check of diameter of the cylinder with the help нутрометра
Check by means of a nutromer internal diameter of the cylinder and by means of a micrometer – external diameter of the piston (fig. 3.9)
If the gap between the piston and the cylinder exceeds maximum permissible size, replace the main cylinder or the piston.
Maximum permissible gap between the piston and the cylinder: 0,15 mm.
Put working brake DOT3 or DOT4 liquid on a mirror of the cylinder and an external surface of the piston.
Insert the piston into the cylinder.
Establish a lock ring of the piston.
Establish a pusher (see details of the main cylinder) (fig. 3.10)
Attach a hose to the cylinder case.
