E-Rock
Additional Mounting Instructions for E-Rock Assembly
The E-rock is generally assembled by the same procedure as any other standard M-Rock. Only the Rock-Extension and
a Counter Nut have been added. The Back-up ring will act as an axial bearing if the Counter-Nut is in place and has
been directly adjusted.
Rock-Extension pre assembly:
1. Place the pivot shaft onto the rock and push it against the “stop” before tightening the screws.
2. Push the Rock-Extension supplied with O-rings over the pivot shaft and into the Rock.
3. Extension and Rock are held together by two screws.
4. Protection-Ring is placed inside the Extension and spot welded at four places around the circumference.
