Fig. 18: Placing the high-pressure stage on the bracket
1. Lightly lubricate hole into which centering bush (42193) is inserted with screw grease.
2. Position threaded rod with centering bush into bracket and insert until stop.
3. Carefully lower high-pressure stage onto bracket and position using the centering
bushes (42193) located in the bracket.
4. Check value x.
If value x is not reached, the high-pressure stage must be lifted up from the bracket and
realigned.
5. Screw threaded rod into bracket up to value L using hexagon.
If value L is not reached or the threaded rod jams while being screwed in, the threaded
rod must be loosened by no more than ½ revolution (this will loosen the centering bush
which may have jammed the rod). Then continue screwing in.
If value L is not reached, undo the screw connection, carefully take the high-pressure
stage off the bracket and repeat the procedure starting with Step 1.
