FO-4 I&T (Remastered Ver.1.2 ) 05-24-2015
13. SECTOR ARMS BACKLASH. Before adjusting sector mesh, make sure that wormshaft
bearings are correctly adjusted as outlined in paragraph 12. Make sure that drag
links are disconnected at sector shaft arms and back off right and left side sector
adjusting screws (Fig. FO12A) two full turns. Turn steering wheel to mid or wheels-
straight-ahead position. Now, using a screwdriver rotate the right hand sector
adjusting screw (viewed from rear of tractor) until all backlash is removed from
right sector arm. Correct adjustment is when 2 to 3 pounds of pull is required to
maintain the steering wheel in motion through the straight ahead or mid-position,
drag links disconnected and opposite sector adjustment backed off. After adjusting
the right hand sector as just mentioned, repeat the procedure on the left sector. A
pull of 2-1/2 to 6 pounds (measured at rim end of wheel spoke) should be required
to maintain the steering wheel in motion through the mid or straight-ahead position
after both of the sectors and the steering post bearings have been adjusted and
drag links disconnected.
14. OVERHAUL. Major overhaul of gear unit necessitates the removal of the unit
