Tools Required
  1. Lifting device for control had 
  2. Removing/Installing tool
  3. Circlip pliers
  4. Double open end wrench

Connecting rod head
Piston pin with removal tool

  1. Mount lifting device to connecting rod head, hang device onto lifting gear and raise slightly in order to relieve the piston pin.
  2. Remove the circlips and push out piston pin. Before doing so, secure the piston against canting.
  3. Carefully lift out connection rod head from the piston and lower  it which care onto a suitable support.
  4. Install device in piston pin and clamp it with hexagonal screw.
  5. Hang device onto the lifting gear and carefully push out the piston pin the full way.
Note: In case replacement of bush is required,this work should be carried out in a service workshop as the bush is to be cooled down before being installed. In the meantime and if possible, install spare connecting rod head. Rescraping the running surface must neither be made with new nor with used bushes.

Check to see that the slipper is free to move, supply pipe fully pressed into the piston skirt.
Installing the piston pin is a reversal of the removal procedure. When installing, attention should be paid no to damage the piston with the device during insertion.>
