MAINTENANCE—REPLACE CONVEYOR ROLLERS
Now you are ready to move the rollers.
F. Remove old roller covering by very carefully slitting the
covering and pulling off.
G. Clean all rollers, using steel wool or a wire wheel. Make certain
all rollers are smooth and free of residue or burrs.
H. Fit the new silicone rubber tubing onto each roller and work on
by hand at least 1/2”. At the opposite end of the tubing, attach
and secure an air supply hose of low pressure, maximum
pressure 5 lbs. While the tubing is slightly expanded by the air
pressure, push the tubing onto the roller. Be very careful to
hold the roller at all times so it does not escape due to the air
pressure.
I. Replace rollers on conveyor by inserting roller end holes into
the extended pins on the chain
J. Check conveyor chain tension as described on page 37.
