SYMPTOM
The blades are moving irregularly
PROBLEM
Blades?
Blade crosshead?
Blade arm bent?
Arm bush?
Worn bearing?
Bearing bush?
Worn thrust bearing?
Make sure that the blades are in good condition, without
excessive wear. Finishing blades must measure at least 5cm
wide for each side, counting from the fixing bracket (which is
in the center of the blade) to its end.
Check that all blades are set to the same pitch angle as
measured on the blade holders.
Check the crosshead for curvature in the arms of the blades.
If one of the arms is bent more than the other arms, replace
it immediately.
Check the tightness of the paddle arm bushings. This check
can be done by moving the arms up and down. If there is
more than 3.2mm of play at the end of the arm, the bushings
must be replaced. All bushings need to be changed at the
same time.
Check the bearing by turning it on the crosshead.
If there is a variation greater than 0.5 millimeters, replace it.
Check it by swinging the cross. If the crosshead skews more
than 2.4 millimeters measured on the outside diameter of the
collar, replace the bearing bushing.
Check thrust bearing to see if it is rotating freely, replace if
necessary.
