The pre-tension of the foundation bolts (holding down studs) must be checked at
longer intervals e.g. during overhauls (see 0380−1).
In the area of the thrust bearing the foundation may be fastened with foundation
bolts 6 and sleeves 8 (Fig. ’A’) or with foundation fitted studs 7 (Fig. ’B’).
The remaining area is fastened with foundation bolts 6, however without sleeves 8
(Fig. ’C’).
