With a compass key, unscrew the lower
ring nut.
Extract the bushing from the block housing.
The internal thrust washer will remain at the
bottom of the block housing.
Now the bore can be machined in the bushing
to suit coupling requirements.
The same procedure is also used for possible
maintenance.

It is advisable to wash the dismantled
parts with a suitable solvent; dry them with
compressed air; make sure that there are no
metal filings or foreign bodies; spread a film
of grease on all parts (for grease type, see
chapter 4, Lubrication).

following the reverse order of the disassembly;
tighten the lower ring nut with thread sealant
LOCTITE 270 or equivalent, making sure the
bushing still rotates freely; fix the unit to the
gear reducer as described further on.
