•
Complete the disassembly of the old disc packs by pressing the sleeves (3F) out of the
holes in each spacer flange.
•
Identify the fasteners which attach the disc packs to the spacer flanges. Disassemble the
loosely assembled nuts (3D).
•
With the bolts (3C) in position, carefully press on the bolt heads to push the new sleeves
into the holes in the spacer flange. Take care not to over-strain the flexible discs.
•
Place a small amount of threadlocking compound (e.g. Loctite 242) on the protruding bolt
threads and then assemble the nuts (3D). Tighten these nuts evenly to the correct spacer
bolt tightening torque value given in Table 1.
•
Complete the refurbishment of the transmission unit by replacing the second disc pack
assembly.
•
Having rebuilt the transmission unit, it is recommended that the shaft alignment be
checked prior to re-installation.
•
The refurbished transmission unit should be installed in accordance with the instructions
for fitting a new coupling.
IMPORTANT Hub bolts should be replaced every time the coupling is dismounted.
ATTENTION:
REPLACEMENT OF THE DISC PACK ASSEMBLIES INEVITABLY
CHANGES THE INHERENT BALANCE OF THE TRANSMISSION UNIT. HENCE, IF A
BALANCED COUPLING NEEDS REFURBISHING, IT IS RECOMMENDED THAT A
FACTORY ASSEMBLED AND BALANCED TRANSMISSION UNIT BE FITTED TO ENSURE
FUTURE, VIBRATION FREE OPERATION. IF REPLACEMENT DISC PACK ASSEMBLIES
ARE FITTED TO A BALANCED TRANSMISSION UNIT, THEN CONSIDERATION MUST BE
GIVEN TO REBALANCING OF THE REFURBISHED TRANSMISSION UNIT OR IN-SITU
BALANCING OF THE COUPLING.
