• Press out worn bearing bushings.
• Press in two 4B130 Bushings at right angles with the side face of 4G80=N4.
• Ream the bushings using 727S9=12G7 Reamer.
• Lubricate the bushings with 633F30 Special Lubricant.
3.4.2 Lubrication
For lubricating the plastic components 633G6 Lubricant is recommended.
For lubricating metal parts sliding against each other such as Tappet (7) and Bearing Axle (24)
