Chain and Sprocket Replacement (See page 6-1A.)
Two sprockets are used to drive the drum screen cylinder: a small keyed hub
sprocket (drive sprocket) is found on the output shaft of the reducer and a large two-
piece sprocket (driven sprocket) is found on the drum screen cylinder.
To disassemble the chain drive, release chain tension (loosen the chain tensioner),
remove master chain link and remove chain.
The smaller sprocket, or drive sprocket, can be removed for replacement by
loosening the setscrew in the hub and pulling it off the output shaft with a puller. For
alignment purposes when reassembling, you may want to scribe a line for reference
on the reducer shaft before the hub is removed.
CAUTION
DO NOT HAMMER ON THE SPROCKET OR HUB. HAMMERING ON THESE
PARTS WILL DAMAGE THE BEARINGS IN THE REDUCER.
When replacing the hub on the shaft, apply an anti-seize compound between the
hub and the shaft to prevent corrosion.
The larger or driven sprocket is bolted to the head of the screen cylinder and
because it is a two-piece sprocket it assembles easily.
Remove the sprocket sections by removing the bolts and carefully maneuvering the
sprocket sections off the machine. When reassembling the sprocket, tighten all the
bolts "finger tight" and align the sprocket teeth at the split, using a section of chain
for a gauge.
If the drive hub has been lined up with the scribe mark you made before taking it off,
the alignment should remain as it was before disassembly.
To check the alignment, lay a good steel straightedge across the faces of the two
sprockets. You will be able to see which way the drive sprocket must be moved to
be in line with the driven sprocket.
Trunnion Wheel Replacement (See page 6-3A.)
The trunnion wheels support the drum screen cylinder and allow the screen to rotate
freely. The trunnion wheels are sized according to drum screen cylinder weight and
diameter. Trunnion wheels are made of UHMW polyethylene material. They should
be replaced if they are worn beyond limits (See Maintenance Section).
