Insert the replacement measurement cable down through the cable guide and
through the angled hole in the spool.

Place a crimp over the end of the cable (inside the spool) with as little excess
cable showing as possible.
21.
Squeeze the crimp with a crimp tool or a pair of pliers to secure it on the cable.
22.
While keeping slack out of the measurement cable, replace the spool over the
main shaft and into the housing. Push it in as far as it can go.
23.
Re-tighten the spool lock screws.

Attach the end of the cable to an external post to keep tension on the cable.
25.
Carefully release the spring winding tool and set aside.
26.
Allow the cable to wind onto the spool by slowly moving the housing towards the
post.
27.
Release the cable end from the post
28.
Extend and retract the cable a few times to check for smooth movement of the
cable.
29.
Replace the endplate.
30.
Replace the 4 small phillips head screws holding the endplate in the housing.

If unit has a potentiometer, check potentiometer for damage. If cable has been
free-released or broken, the potentiometer may be broken. Turn the potentiometer
shaft all the way in both directions. The shaft should rotate smoothly with no
resistance until it suddenly stops. If rough spots, resistance, or "soft" stops are
felt, the potentiometer is damaged and must be replaced. Contact Celesco for new
potentiometers and replace if necessary.
32.
On the sensor mounting bracket, position the locking nut on the edge such that a
flat side of the nut is parallel with the edge of the sensor bracket. Do not tighten.
33.
Replace the o-ring and install the bracket and seat it snugly in the housing. Make
sure the legs of the clutch spring are in between the wider set of posts on the
spring arbor. Make sure the o-ring is seated correctly.
34.
If your transducer is a PT8150 skip to step 38.
35.
Connect a 10 VDC power supply to the potentiometer terminals so +10VDC is
connected to CCW and –10VDC is connected to CW.
