Installing the PE
Assembly
Follow the steps below to install the programming electronics assembly
in the 2500.
1. Turn off the 2500 and remove the power cord.
CAUTION: Pins in the pin block are delicate and could be damaged if
they hit components mounted on the underside of the main
plate. The pin block cover ensures that these pins are not
damaged while you are removing or reinstalling the PE
assembly.
2. Carefully slide the PE assembly onto the clamp assembly. Figure 7-7
shows the two tracks on the clamp assembly that fit into grooves on
the pin block.
3. Install the retaining bar and its two hex screws to connect the PE
assembly to the clamp assembly.
4. Reconnect the two optic cables (S-24 and C-25).
5. Reconnect the two of the four air lines (one red and one blue) to the
rear quick connects.
6. Hold the programming module clamp assembly in place and reinstall
the six 7/64-inch hex screws.
7. Reconnect the two remaining air lines (one red and one blue) to the
front quick connects.
8. Reconnect all of the remaining cables.
CAUTION: When you connect the cables, be careful to use the correct
polarity of the cables to the connectors. Reversing or
misaligning a cable could damage components on the 2500.
9. Connect the 2500 to a compressed air source and check for air leaks
by listening for a hissing sound.
10. When you determine that there aren’t any air leaks, lower the main
plate.
11. Tighten the two corner screws in the main plate (see Figure 7-3).
Motor Replacement
These procedures explain how to replace any motor that may have failed.
Replacing the Input
Orbital Motor
Follow these steps below to access and replace the input orbital motor.
1. Turn off the 2500 and remove the power cord.
2. Remove the PE assembly, as described on page 7-3.
3. Locate the round input orbital motor collar. Loosen the 7/64-inch hex
screw and remove the motor collar.

4. Remove the two 3/32-inch hex screws that hold the rear orbital
alignment block to the underside of the main plate. Slide the rear
orbital alignment block off the dowel pin, and let the block dangle
from the cables.
5. From above the main plate, remove the two 3/32-inch hex screws
that hold the front orbital alignment block to the main plate. Remove
the front orbital retaining block from the underside of the main plate.
6. Support the left side of the orbital assembly while you remove the
7/64-inch hex retaining screw (with the white plastic standoff) on the
right support brace.
7. Remove the 3/32-inch hex screw that holds the grounding strap to
the right support brace.
8. Carefully slide the left side of the input orbital assembly off the
orbital cam spindle. Be careful that the white bushing between these
two is not lost or damaged.
9. When the assembly is off the spindle, slide it to the left until it is free
from the right support brace. Let it dangle from the cables.

10. Remove the orbital cam from the motor shaft. Now you are ready to
remove the input orbital motor.
11. Unplug the Molex motor cable J-12. The end of this connector is
located under the main plate and will not fit through the main plate
hole. Remove the four pins in the connector to free the cable. Note the
wire colors and positions in the connector (see Figure 7-9).
12. Use a Molex pin extractor tool to remove the four pins from the white
plastic connector.
13. After removing the four pins, pull the cable through the main plate.
14. From below the main plate, remove the four 1/16-inch hex screws
that hold the input orbital motor to the main plate.
15. Lower the main plate and remove the input orbital motor.
16. Place the new input orbital motor in position on the main plate. Make
sure the power cable is oriented to the right side of the new input
orbital motor.
17. Guide the motor cable through the hole in the main plate.
18. Insert the four motor wires into the white plastic Molex connector. Be
sure to insert the wires in the same order (and orientation) as shown
in Figure 7-9.
19. The input orbital motor shaft has one flat side. Turn the shaft until the
flat edge faces the front of the 2500.
20. The orbital cam has a small hole on its outer edge. Position the cam
on the motor shaft so this small hole is positioned on the right side
(input side) of the shaft.
CAUTION: As you reinstall the input orbital assembly, make sure the
white bushing that fits over the spindle stays in position.
21. Reinstall the input orbital assembly (in reverse order from the
procedure in steps 6-9 above).
22. Reinstall the front and rear orbital alignment blocks.
