Cyclo® Portion – General Reassembly
The Cyclo® portion of the speed reducer may be reassembled by reversing the disassembly procedure. All parts must be returned to the
original order from which they were removed during disassembly. Take care to keep the moving reduction components free of dust or
foreign material, and properly align all gaskets in order to keep the assembly oil tight/leak free.
Remember these important notes when assembling the Cyclo® reducer:
1
Place the ring gear housing on the Cyclo® high speed end shield (or the motor
flange) and insert the ring gear housing pins and rollers (if they had been removed
during the disassembly process). Rotate each of the pins and rollers by hand to
assure that they freely move/rotate.
If the Cyclo® portion of the Cyclo® BBB4 is grease lubricated, liberally apply grease to
the ring gear pins and rollers before they are inserted into the ring gear housing.
If the Cyclo® portion of the Cyclo® BBB4 unit is oil lubricated – do not
add any grease during the reassembly process.
2
Cycloid discs are a matched pair, both discs have the same code etched on one side.
When inserting these discs into the ring gear housing, be sure that the etched
number is facing up.
3
When reinserting the eccentric bearing assembly, use only a wooden or hard
rubber mallet to tap it into place.
