Put the parts together in the reverse order of disassembly, with the precautions given below.

(1) Apply machine oil to Felt Packing (B) 

[23]

 then mount it to the Packing Gland 

[26]

 to increase the dust

resistance.

(2) Generously lubricate the teeth of the Gear and Pinion Set 

[33] 

with grease. Rub grease onto the teeth

with your fingers so that the grease reaches each tooth bottom. Note that under-lubricated Gear and

Pinion Set 

[33]

 may wear at a faster rate.

(3) When replacing the Armature

 [10] 

and the Ball Bearing 6000VVCMPS2L 

[15]

 on the commutator side,

press inward on the Dust Seal 

[14]

 while taking care of its direction until the end face of the Dust Seal

[14]

 hits against the butting surface of the Armature 

[10]

 and make sure that the Dust Seal 

[14]

 cannot

turn freely. (See Fig. 3.)

The Dust Seal 

[14] 

is an important element for improved dust protection of the Ball Bearing

6000VVCMPS2L 

[15]

. Be sure to use a new one at every disassembly work of the Ball Bearing

6000VVCMPS2L 

[15]

.

(4) Apply Three Bond TB 1406 Screw Locking Agent to the following screws.

• Two Seal Lock Screws (W/Sp. Washer) M5 x 14 (Black) 

[1] 

which fix the Bearing Cover 

[9]

 in place.

• Four Hex. Socket Hd. Bolts (W/Flange) M5 x 16 

[27]

 which fix the Packing Gland 

[26]

 in place.
