Assembly
The bottom leg of the spring (-arrow 1 - → upper illustration) can spring down uncontrolled from the selector bracket shoulder during subsequent handling.
-- Carefully press it down from the selector bracket shoulder.
The spring sides then twist "diagonally" with a loud noise.
-- Turn both springs to the right and release the tension on the legs -A and B-.
- The legs -A and B- must point in opposite directions. (Shown here with the shift lever guide inserted.)
-- Insert the shift lever guide and the shift lever into the shift housing.
- The pins -arrow 1- are still located in the shift housing opening.
-- Turn the shift lever guide in the -direction of arrow 2- until the ball head pin -A- is above the opening in the shift housing.
-- Install the shift housing with shift lever guide into the large depression -arrow- in the thrust blockT10083.
- The shift lever guide must project out of the selector housing as far as the stop.
-- Insert spring leg -A- from above into the guide.
-- Pull spring leg -B- down and insert it near the guide (in the direction of the ball head).
The selector bracket is only partially shown to provide a better illustration.
-- Carefully remove the shift housing with the shift lever guide from the thrust blockT10083.
-- Move the selector bracket all the way to the rear (opposite mounting holes for shift and selector cable) -arrow 1-.
-- Lubricate ball head pins.
-- Press ball head pins into selector bracket -arrow 2-.
- The guides -A- and the tabs -B- must not be damaged.
-- Install the shift housing with the shift lever guide into the large depression -arrow- in the thrust blockT10083.
- The shift lever guide must project out of selector housing as far as the stop.
-- Raise the upper leg -A- of the spring over the selector bracket pins.
- Use a new bearing shell -B-.
-- Lubricate the bearing shell and shift lever guide bearing.
-- Press the bearing shell onto the shift lever guide bearing as far as the stop.
-- Remove the shift mechanism from the thrust blockT10083.
-- Press the bearing shell into the selector housing -arrows-.
