The internal thrust washer will remain at the bottom of the block housing.
The bore can now be machined in the bushing to suit coupling requirements.
The same procedure is also used if maintenance becomes necessary.
3.2.2.2 Re-assembling the Internal Parts
It is advisable to wash the dismantled parts with a suitable solvent and dry them with
compressed air. Make sure that no metal filings or foreign bodies remain; spread a film of
grease on all parts (for grease type, see Section 4, Lubrication). Proceed with assembly
of the internal parts by following the disassembly procedure in reverse order; tighten the
lower ring nut with thread sealant LOCTITE 270 or equivalent, and ensure that the bushing
still rotates freely. Attach the unit to the gear reducer as described further on.
