[3] Disassembling and Assembling
1) After removing Carbon brushes, remove Grip 36 complete.
Separate Head cover from Gear housing by removing two
M14x10 (+) Round head screws with Phillips screwdriver
No.3 or the like.
2) Separate Gear housing section from Motor housing
by removing four 5x30 Tapping screws.
3) Slide Gear housing cover until you see the corners of
Motor housing. Then by striking two of the corners with
plastic hammer, the assembly of Armature and Gear
housing cover can be separated from Motor housing.
(Fig. 2)
4) Remove Hex nut M6 by turning it counterclockwise
with a wench 10 while holding Armature firmly by hand.
Spiral bevel gear 9 can now be removed from Armature
shaft by hand.
5) Remove Gear housing cover from Armature using 1R045 and 1R346. (Fig. 3)
Ball bearing 6201LLB is still on Gear housing cover in this step.
6) Remove Ball bearing 6201LLB using arbor press and a round bar. (Fig. 4)
Note: Disassembling can be done without disassembling
Gear housing section.
CAUTION: For your safety, before maintenance or repair, be sure to;
1. Disconnect the machine from the power source.
2. Remove the abrasive disc from the machine.

1) Insert Ball bearing 6201LLB straight into Gear housing cover. Put 1R035 on arbor press, then put Gear housing cover
on 1R035. Press-fit Armature to Gear housing cover using arbor press. (Fig. 5)
2) Install Spiral bevel gear 9 on Armature shaft, and tighten Hex nut M6 securely with a wrench 10.
Then install the assembly of Armature and Gear housing cover on Motor housing, and align the screw holes on Gear
housing cover with those of Motor housing.
3) Aligning the protrusion on Gear housing with that on Motor housing, fit Gear housing to Gear housing cover. (Fig. 6)

DISASSEMBLING
Do the reverse of the disassembling steps.
Note: When assembling Spiral bevel gear 43 to Spindle,
be careful not to allow Woodruff key 4 to be out of position.
It is recommended to apply grease to the key slot on Spindle
in order to hold the Woodruff key securely in place. (Fig. 11)
1) Remove Bearing box from Gear housing. (Fig. 7)
2) Pull off Shoulder pin 7 with pliers while pushing Pin cap with a
finger. (Fig. 12)
Note: Do not pull off Shoulder pin 7 without holding Pin cap
because Compression spring 7 would sling Pin cap.
Do the reverse of the disassembling steps.
Note: Do not reinstall removed Pin cap because removal of Shoulder
pin 7 damages the inside surface of Pin cap. Be sure to remove
plastic dust of Pin cap from Shoulder pin 7 and to assemble it
to a new Pin cap.
