"-18 x 2 hex bolt into helical pinion
gear threads (see
Figure 14).
34. Remove wood board and gently tap hex bolt
dead center with hammer until cutterhead is
unseated from carriage (see
Figure 14).
35. Pull cutterhead through right bearing bore.
36. Use a 32mm deep well socket or wood block
to remove left bearing from bore.
Note: Focus impact to bearing on outer race
(see
Figure 15). Take care not to damage
rubber seal.
1. Remove spiral cutterhead from packaging.
2. Lightly oil left and right bearing bore surfaces
and remove any dust or dirt.
3. Lower cutterhead into carriage while guiding
threaded end through right bearing bore (see
Figure 16).

5. Seat 6202-2NSE ball bearing into left bearing
bore using hex bolt as an alignment guide.
6. Use a 32mm deep well socket or wood block
to gently tap bearing into bore until retaining
ring groove is visible. Bearing will be flush
with internal carriage wall when fully seated.
Note: If using a wood block to install bear-
ings, ensure that impact is evenly distributed
around outer race to prevent bearing tilt (see
Figure 17).
7. Re-install retaining ring into bearing bore
groove.
We strongly recommend using the new replace-
ment bearings included with the Model T32591,
even if the existing bearings appear to be in good
condition.
Wrap the new bearings and place them in a freez-
er overnight. This will cause the bearing metal to
contract, making them easier to install.
