3.
Mark and remove motor electrical leads.
4.
The motor is secured with four screws to a flange plate. See Figure 5.1.8
5.
Because of the weight and size of the spindle motor, and the restricted working space, extreme
caution should be used in sliding the motor from its mounting plate.

Aligning Tailstock to Spindle
If there is taper appearing on the workpiece while machining when using the tailstock, the tailstock
will need to be realigned to the spindle. Follow the steps below.
1.
Insert a gage bar between the spindle and tailstock, attach a base of a dial indicator to the
saddle, apply the needle of the indicator to the surface of the bar, then move the saddle
through the longitudinal travel. Document the measurement of its maximum difference from
end to end for later adjustment.
2.
Release the 4 bolts labeled “A” in the drawing.
3.
Release the screw labeled “B”.
4.
Adjust screw “C” until the tailstock is aligned with the spindle.
5.
Tighten up the locking nuts “A”.

Spindle Motor Wiring
The TRAK Lathe spindle motors are wired for 208 volts (low voltage configuration). The wiring
consists of 3-phase power for the motor and 208 volt power for the spindle motor fan. Please see
the motor junction box diagram for wiring information.
Each junction box contains 6 terminals. Make sure to hook up the wires to the same terminals after
the replacement motor is installed. Failure to do so may cause the motor to run in the wrong
direction.
The spindle motor fan wires are also found in the junction box. There is 1 hot wire, 1 neutral wire
and 1 ground wire. It does not matter which wires are connected to the hot and neutral wires. All
grounds from each cable are connected to either of the screws in the junction box.
