FSDR .. K housings must be mounted properly using the appropriate tools and state of the art mechanical mounting methods.
Mounting instructions for the housings are available on request.

Torque specifications

The M 24 cover bolts supplied with all housings should be tightened to 665 Nm. The cover bolts are in accordance with ISO 4014:2011.
The M 12 labyrinth ring bolts (in accordance with ISO 4017:2014) supplied with the labyrinth seals should be tightened to 80 Nm.
Cap bolts should be tightened to the torque values listed in table 1.
For information about attachment bolts, refer to Attachment bolt recommendations.

Ventilating valves

The ventilating valves should be installed on top of the housing cap for use when the housing is in operation. The holes for the valves are plugged on delivery.

Eye bolts and lifting holes

FSDR .. K housings have a cast hole in each integral flange on the cap and one M 16 eye bolt in each cover half (fig. 1) for safe, easy handling. The labyrinth rings are equipped with adjustable eye bolts (VLBG 0.63t M 10 with bolt, except for size 49/1320, which has M 10 eye bolts) that can be removed after mounting.

Supporting the housing

FSDR .. K housings require two stops, one on each side of the housing, to accommodate loads acting parallel to the housing support surface.
