Replacement Spindle Cartridge Assembly ........ 1
The spindle cartridge assembly features factory-
sealed bearings. A sealed bearing requires no
lubrication during its lifetime.
Should a bearing fail, your shaper will probably
develop a noticeable rumble, which will increase
when the machine is put under load. If allowed to
get worse, overheating of the journal containing
the bad bearing could occur, which may cause
the bearing to seize and possibly damage other
parts of the machine.
Rather than disassemble the spindle cartridge
to remove the bad bearings, Grizzly offers
replacement spindle cartridge assemblies (Part#
P0510Z317) as whole units, which makes replace-
ment very simple. The whole procedure can be
accomplished in 15-20 minutes.
To replace the spindle cartridge assembly:
1.
DISCONNECT SHAPER FROM POWER
SOURCE!
2.
Remove the spindle and drawbar from the
spindle cartridge assembly. (Remove tapered
drawbar nut and tap the drawbar up to knock
it loose.)

the two mounting bolts shown in

4.
Loosen the two motor mount bolts, slide the
motor forward, and remove the V-belt.
5.
Loosen the spindle lock knob.
6.
Remove the cartridge nut on the bottom of
the spindle, as shown in
Figure 44
, and slide
the pulley off.
7.
Hold your hand under the spindle cartridge
and remove the elevation handle by unthread-
ing it counterclockwise. The spindle cartridge
should drop into your hand.
8.
Install the new cartridge assembly in the
reverse order of disassembly.
