HANGER BEARINGS
The hanger bearings may be replaced by removing the entire hanger assembly
from the screen. The screen can be supported on the remaining three hangers
while the fourth is being serviced. The U-joints are replaced by using a
replacement kit consisting of the cross, four bearings and a set of snap rings.
NOTE: The screen should not be operated while hanging on only three
hangers.
Whenever a hanger is changed out, the loading on all four hangers should be
checked again to ensure equal loading. See installation instructions on page 7.
DRIVE BELT
The drive belt adjustment is made outside the screen, at the motor.
1. Loosen the nuts on the adjusting rods and pivots.
2. Adjust the nuts to increase tension.
3. Tighten all nuts securely.
Belt replacement – see the exploded drawing and instructions on page 27.
Note: When the top cover is removed it is essential that the three 1” bolts
be torqued as follows:
The three 1” bolts must be fully torqued to ensure the shaft is properly seated
into the taper. It is essential that the three 1” bolts be torqued to 480 ft-lbs as
many times as necessary since the first bolt will be loosened as the third one is
torqued. Failure to follow this procedure will result in serious damage.
