The cutterhead runs in two single-row sealed
and shielded ball bearings, which are pre-
lubricated for life - no maintenance is
necessary.
CUTTERHEAD REPAIRS
The entire cutterhead assembly may be
removed for bearing replacement or other
cutterhead maintenance procedures.
To remove the cutterhead:
1.
Disconnect machine from power source.
2.
Lower infeed and outfeed tables.
3.
Remove rabbeting ledge and fence.
4. Remove
belts.
5.
Loosen the two bolts that hold the
cutterhead to the bed – these are
accessed from the underside of the
bearing blocks as shown in Figure 25.
6.
Slide the cutterhead out the rabbeting
side.
CAUTION: Before removing
cutterhead, wrap it with cloths to
prevent personal injury.
7.
Loosen lock screw (A-Fig. 26) and
remove pulley (B-Fig. 26) and key (C-
Fig. 26).
8.
Take down screws (D-Fig. 26) on both
sides and remove bearing cap plates (E-
Fig. 26).
IMPORTANT: If the bearings (G-Fig. 26)
need replacement, Powermatic strongly
recommends this be done by qualified service
personnel. The bearings are press fitted and
must be removed with an arbor press.
9.
To re-install the cutterhead, reverse the
above procedure. NOTE: Before
reinstalling, make sure the machine's
curved seats of the base casting are free
of dirt, dust or grease, to help ensure a
tight fit.
