It is recommended to fix on the motor shaft a screw stay (2) on which a nut (3) is tightened possibly resting to a thrust bearing (4)(see Fig.1).It is indispensable to lubricate the motor shaft before mounting the coupling.Check that the coupling shaft rest on the motor shaft shoulder and lock by means of screw (5), spacer (6) (see Fig.2)1M4RB4Fig. 132Fig. 21) 1) Demount the ROTOFLEXI rubber element (F) as shown at Fig.12) 2) Fit the ROTOFLUID hydraulic coupling (A) on the motor shaft(M), fit the ROTOFLEXI hub (B) on the driven shaft ©. Assure that the drivenshaft is coaxial with the hydraulic coupling (A). The concentricity is assured when it is possible to fix the hub (B) to the hydraulic coupling flange(A) by means of the screw (D), as shown at Fig.2. It is now possible to fix definitely the motor and the driven machine checking that betweenthe hub (B) and the driven shaft shoulder there must be a space (E) equal to the thickness of the rubber element (F).3) Remove the screws (D), move the hub (B), place the rubber element (F), lock the screws (G) and (H) as shown at Fig.3.50BFig. 35
