b.
Adjust.
(1)
Largest backlash is recommended to be
less than 1/8 in. (0.32 cm). If backlash is
greater than 1/8 in. (0.32 cm), two
joints (7) between circle and blade can be
tightened.
NOTE
More probable points to inspect are
wear strips between blade slide rails
and blade brackets.
(2)
Tighten joints after replacing wear strips
and shims.
(3)
Tighten blade roll backlash at this time.
(4)
After this side has been side shifted to its minimum clearance position, (see Para 3-34), wear strips
can be formed to provide clearance of 0.005 to 0.035 in. (0.013 to 0.089 cm) between sides of rails
and wear strips.
(5)
Second joint to inspect is blade pivot pin (8). If movement at pin is 1/32 in. (0.079 cm) or more,
notify Direct Support Maintenance.
WEAR STRIP AND SHIM REPLACEMENT.
NOTE
Sensor calibration is required after these procedures (see Para 3-15).
Use shims as required to obtain 0.005- to 0.035-in. (0.013 to 0.089 cm) clearance between
rails and wear strips at minimum clearance position found by sideshifting moldboard
through full range with shims divided as equally as possible between top and bottom
wear strips.
(1)
Install wear strip (9) and shims (10) on
the slide rail (3) and in bracket (11).
(2)
Position blocks (12) and install bolts (13).
