When completing a maintenance
function, make sure all shields are in
good condition and are installed

BELT REPLACEMENT
(refer to Fig. 15)
Major causes of belt failure are improper instal-
lation and tension. Before installing a new belt,
check spindle shafts and bearings for excessive
end play and wear by moving each spindle shaft
side to side and up and down. Be sure they turn
smoothly and freely. Make sure idlers are still
aligned with spindle sheaves. Check sheave
grooves for cleanliness and wear. If grooves re-
quire cleaning use a cloth moistened a with
nonflammable nontoxic degreasing agent or
commercial detergent and water.
Avoid excessive force during installation. Do
not use tools to pry belt on or roll belt over
sheaves. This can cause hidden damage and pre-
mature belt failure.
