the component is re-assembled and installed in exactly the same location and orientation!
PROCEDURES
Removal
CAUTION: It is advisable to heat up the teeter block in an oven. When removing the teeter
block marks all parts or use cable ties so that each and every part of the component is re-
assembled and installed in exactly the same location and orientation! This is especially
important for the shim plates between teeter block and hub bar.
WARNING: Affected aluminium parts must not become warmer than 160 °C.
1 Remove bushings from teeter block. In order to do so warm up teeter block to 120 °C, preferably in an oven.
2 Use appropriate tools to drive out bushings. Be careful not to damage the surface of bore.
3 Remove bushings from pre-heated teeter tower.
4 Use appropriate tools to drive out bushings. Be careful not to damage the surface of bore.
