Remove two long bolts securing bearing cover. 

 

Bearing  is  firmly  secured  and  so,  after  hitting  the  shaft 

from  the  front  with  soft  hammer  and  bearing  can  be 

dismantled easily by using two long bolts as shown. 

 

Be careful not to damage the shaft with 

excess hitting

.   

 

WARNING 

 

Bearings on drive and idle shaft can be dismantled. 

 

 

 

Shim  should  be  carefully  kept  not  to  be  lost  for  the 

assembly. 

Quad ring is protecting bearing when a leakage occurs.
