the deburring unit's rear housing.
2. Remove the socket head screws securing the rear housing to
the deburring tool's front housing.
3. Remove the rear cover complete with the pivot bearing. Retain
the small o-ring and dowel pin between the cover and housing
for reuse if desired.
4. The new rear housing assembly will be provided with new
fasteners and a new o-ring. Reassembly is the reversal of the
previous steps with the following points:

Insure the dowel pin and small o-ring that go between the
housing and the rear cover are in place before refitting the
rear cover.
✓
Use liquid thread locker on all the socket head screws, but
NOT on the brass pivot post plug (where applicable).
✓
Insure that the spindle air supply fitting is centered in the
housing (side boot) opening prior to tightening the fastener
in the pivot bearing post.
