Before mounting, all parts belonging to the round guide must be carefully cleaned and wet slightly using low-viscosity machine oil without additives.
Assembly of series FDK – FDL:
Insert the guide bushing in the housing borehole. If there is an orientation pin mounted, this must not come to rest axially against the groove in the housing.
Mount the flange cover loosely without the shim ring.
Insert the centre sleeve.
Tighten the clamping screws in the flange cover evenly crosswise until loss of play in the centre sleeve is indicated by stiffer sliding action. Check the parallelism of the mounting gap for the shim ring and correct if necessary.
Gauge the mounting gap for the shim ring, remove the flange cover.
Adjust the high of the shim ring. Recommendation: Measured mounting gap +approx. 0,02 mm for contact surface compression.
Mount the flange cover and the underneath shim ring, tighten the screws crosswise.
Check the guide play. If necessary, correct by reworking the shim ring (reducing guide play) or the flange cover (increasing guide play).Guideline value: 0.1 mm alteration of the height corresponds to ~ 0.01 mm alteration in diameter.
