MAINTENANCE 

 

LUBRICATION:  USE #2 MULTI-PURPOSE LITHIUM GREASE 

 

 

 

To  ensure  longevity  and  reliability  of  the  V.T.A.

  Coulter,  the  recommended  lubrication 

schedule should be followed using multi-purpose grease at hourly intervals as indicated. 
 

 

BEARING ADJUSTMENT: 
 
1.  Raise  the  toolbar  until  the  blade  is  clear  of  the  ground.    Place  a  safety  stand  under  the  toolbar.  

Remove the hubcap, cotter pin, slotted nut and washer from the hub assembly.  Remove the blade 
from the hub assembly. 

2.  Remove bearing cones and seals from hub. 
3.  Wash  the  old  grease  from  the  hub,  bearing  cups,  spindle  spacers,  seals  and  bearing  cones.  

Inspect the condition of the bearing cups, cones and seals.  Replace if necessary. 

4.  Apply #2 multi-purpose lithium grease on each bearing.  Make sure the space around each roller is 

filled.  Lubricate the bearing cups. 

5.  Position  the  bearing  in  the  cup  and  install  the  seal.    Lubricate  the  seal  lips  and  proceed  with  re-

assembly of the removed parts including the blade.  Blade bolt torque is 90 to 96 ft. lbs. 

6.  Tighten the slotted nut to 15 ft. lbs. or until a definite drag is felt when the blade is turned by hand.  

Tighten the nut one-slot position to line up the cotter pin hole with a slot.  Secure the nut with a new
