ruining the undercover, which develops the air pattern. As long as the undercover is 
not damaged, it is not necessary to replace it. When rebuilding a deck, always inspect 
the deck thoroughly. Look at the underside of the deck and inspect each rib for cracks, 
dents, bends or other problems. If the ribs are damaged, it will be necessary to tear 
down the deck completely to repair or replace them. 

 

A.1.2 BELTS AND SHAEAVE: 

 

There are two sets of belts and sheaves in your Oliver Stoner. These are the main 
drive belts or fan belts; and the eccentric belt from the motor to the eccentric shaft. 
New machines should be checked very frequently for the first few weeks, because 
new belts tend to stretch as they are broken in. To check belt tension, turn off the 
machine. Then apply pressure to the out- side of the belt midway between the two 
sheaves. The belt should deflect approximately 1/2 inch. 
 
The  eccentric  belt,  from  the  motor  to  the  eccentric  shaft,  has  a  shaft  running 
through it. The shaft must be removed to install a new belt. For this reason, a spare 
belt  is  installed  around  the  shaft  on  all  new  machines.  When  the  original  belt 
wears out, merely remove the spare belt from its mountings and slip it in place of 
the original. If the second belt wears out and you lack the time required to install 
a  new  belt,  you  can  replace  it  with  a  link  belt.  However,  this  is  a  temporary 
measure; and we recommend the link belt be replaced with standard V belts as 
soon as it is convenient.  Proper tension is maintained on the  eccentric  belt for 
achieve proper eccentric motion. 

 

A.1.3 

 Bearings 

To prolong bearing life, each bearing should be greased with 1 to 2 shots of grease at 
the start of each season. Sealed bearings are installed at the factory and will give much 
better service if they are not over-greased. A bad bearing will normally be detected 
by a rumbling noise in the machine, or by feeling an unusual vibration. To determine 
if a bearing is defective, run the machine for at least 30 minutes. Then, turn off the 
machine and lock out the power supply. Touch the bearing surface. If the bearing is 
excessively hot, it is probably bad and must be replaced.
