D8RE3000 Troubleshooting - Part 3
Step 4:
Holding the piston, press the push rod up and down. It
should click in both directions. If not, please give us a call for
assistance or check out the D8 Piston Shell and Actuator
Assembly Replacement Service Video.
Step 5:
Next, visually inspect the upper and lower flanges on the
piston shell. If they are worn or have deep scratches, the piston
shell (Part #: 8PC002) needs to be replaced.
If either is loose, the piston shell needs to be replaced.
To test the upper flange,
invert the piston
and insert it squarely halfway into the blue
bell housing. It should stay in place.
To test the lower flange,
use the needle nose pliers
to twist the plunger counter
clockwise and remove.
Then, insert the piston
squarely into the body about
halfway - it should stay in place.
