Assembly Procedure for LM Type Couplings
Clean all the parts carefully. 1) Support the spacer between two adapters in such a way that the clear holes of spacer flange will be in line with the press fitted bushes in the adapter. 2) Hold the flexible membrane between the adapters & spacer flanges. 3) Insert socket head cap screws with sleeves from adapter side through the clear holes of adapters, membrane holes & press fitted bushes on spacer and tighten the nylock nut. 4) Then insert the socket head cap screws from adapter side through the press fitted bushes in the adapters, membrane holes and clear hole on spacer flange. Insert the sleeve from spacer side & tighten the Nylock nut. 5) Follow the same procedure from other side also. Then tighten all the nylock nuts to the required tightening torques for disc pack bolts given in the table. 6) Ensure the Gap ‘G’ is equal at both sides of spacer. Value of gap ‘G’ is given in table 1 & 2. Tighten the foundation bolts of both equipments.
Important: If the coupling is dynamically balanced, ensure that the matchmarks are in a straight line & unidirectional before bolting the assembly. The necessity for shields & guards varies with individual installations. The owner or user must provide the required safety guards or shields are not furnished by us with this equipment.
