Housings
The motor housing houses the field, armature and all the other components that makes up the laminate trimmer. If the housing is out of round, or damaged in other ways, it may bind on the base, causing it to be non-adjustable and require a replacement. All the parts can be easily transferred from the old housing over to the new housing.
Replacing the motor housing will vary on all models, as they are different. Through, the following repair procedure will be similar. Remove the base from the unit and the motor cover. Remove the tension springs on the carbon brushes. Separate the upper and lower half of the motor housing. Remove the collet from the shaft then by using a rag, or a thick glove, tightly hold onto one end of the armature shaft as you use an impact wrench to remove the chuck. Tap the armature free of the...

Remove the collet from the shaft then by using a rag, or a thick glove, tightly hold onto one end of the armature shaft as you use an impact wrench to remove the chuck. Tap the armature free of the housing with a rubber mallet. Remove the e-clip inside the housing then tap the bearing free using a socket that contacts the outer race of the bearing to avoid damaging the bearing. Spin the bearing to check for roughness. If it is rough, install a new bearing. If it spins smooth, the bearing is still good.
Install the armature into the new housing by using the same socket to tap it in place and install the retaining clip. Install the armature into the housing and tap into place with a rubber mallet, if needed.
Reinstall the chuck with the impact wrench as you hold on to the opposite end. Reinstall the collet. Remove the brush holders and insulators from the old motor housing and disconnect any wires at the holders. Remove all switches from the old motor housing. Take a picture of the wiring for reinstallation reference. If you have to cut any wires for removal of parts, make sure you cut the wire as close to the crimped ends as possibly, preventing loosing wire length. When re-crimping ends, remove ¼ inch of insulation from the wire when attaching new ends. Remove the screws securing the field in place, then take the field out.
Clean the field with electrical contact cleaner and install into the new housing. Make sure the field is installed correctly for the wires to line up with the connections. Reinstall the switch speed control and brush holders, with insulators, and reconnect all the wires. Join the two halves of the motor housing together. Reinstall the tension on the carbon brushes. Install the motor cover and the base.

Knobs
The clamping knob is used to lock the laminate trimmer in position on the base. If the clamping knob is stripped, or broken, it cannot lock down. To replace the clamping knob, unscrew it and then remove the washer and special bolt. Install the new bolt into the channel (it only enters one way), then install the washer and thread the knob on the special bolt.

Bases
The purpose of the base is to mount the router to it, allowing you to use the router in a variety of different ways. If the base becomes warped, it will impact the quality of your cuts, cause a vibration and can be overall dangerous. Place the base on a flat surface to see if it is warped. The base should be flush, with the flat surface. Touch all around it to make sure it does not move. If it does move, that indicates it is warped and you will have to replace it.
