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 FSK – FSL:
Insert the guide bushing in the housing borehole. If there is a orientation pin mounted, this must not come to rest axially against the groove in the housing.
Tighten the clamping screws in the flange cover evenly crosswise until the guide bushing is seated firmly in the housing. Even actuation of the clamping screws can be achieved by tightening in each case by a certain angular amount (e.g. 30°). Specifying a certain degree of torque for the clamping screws is a less suitable method of ensuring even guide play adjustment.
Insert the sleeve and continue tightening the clamping screws as described above, until loss of play is indicated by stiffer sliding action of the sleeve.
Remove the sleeve, apply a thin coating of inking paste and re-insert in the guide bushing to check the contact pattern.
Move the sleeve backwards and forwards with an oscillating motion, remove and assess the ink impression left on the guide bushing.
Should the surface impression be incomplete, insert the sleeve again and tighten the screws in the sector, which is not making correct contact. Stop tightening when you notice the sleeve running more stiffly in the bushing.
After optimising the contact pattern, clean the sleeve and guide-bushing borehole, oil and re-insert the sleeve.
