SWIFT-LOCK TEETH MAINTENANCE

When the jaw teeth are worn or cracking, performance is decreased and the teeth need to be replaced.

Removing the Upper Teeth

1. 

Locate flat, hard ground and place the attachment 

on the ground. 

2. 

Remove the washers, on each sides of each 

tooth, using a grinder.

Note: The washers are welded into place.

3.  Use a soft metal drift and a mallet to drive out the 

tooth pin.

4.  Remove the tooth from the receptacle.

Note: The retainer ring may fall out when removing the 

teeth. Do not lose the retainer ring.

5.  Insert the retainer ring in its place and insert a 

new Swift-Lock tooth.

6.  Insert the tooth pin and weld the washers in place.

Note: Insert the tooth pin so that the pin groove will 

line up and seat in the retainer ring.

Removing the Lower Tooth Platen

1.  Remove (6) M30 cap screws from the bottom of 

the lower jaw. Do not reuse the cap screws.

2. 

Remove the Lower Tooth Platen.

Note:  There  are  3  dowel  pins  press  fit  into  the  Lower 

Tooth Platen for positioning. Insert new dowels into the 

new Lower Tooth Platen.

3.  Install a new Lower Tooth Platen. Apply Loctite 

262 to the installation bolts and torque to 1350 ft. 

lbs. (1850 Nm).

•  Wear personal protection equipment at all 

times. This includes eye protection, hard hat, 

steel toe shoes, leather gloves and hearing 

protection.

•  Swift-Lock Teeth are very heavy. DO NOT 

remove a tooth pin if the tooth is not 

supported. The tooth may fall and cause injury.
