BLADE PRO MOTOR GRADER CONTROL
SECTION VII.
SYSTEM MAINTENANCE
NOTE
The following section deals with critical wear and maintenance areas of your 130G Grader
and Blade Pro Motor Grader Control System.
Consistent accuracy of your Blade Pro Motor Grader Control System is largely dependent on the
130G Grader's condition. 130G Grader wear varies with job conditions, Operator skills, and materials. The
130G Grader wear points should be inspected on a regular basis.
BLADE CUTTING EDGE INSPECTION.
Blade Wear Inspection. Uneven blade wear
a.
occurs mainly in three locations: on the
cutting edge, arcing from edges to center
creating an upward bow, and from center
wearing to either end. Blade wear can be
checked by placing the cutting edge on or
slightly above a flat surface, such as concrete
or pavement, and comparing cutting edge to
that surface. Maximum deviation from even
wear should be less than 1/8 in. (3 mm) if
accuracy within 1/100 ft (0.003 m) is desired
(TM 5-3805-261-10).
Blade Curvature Inspection. Curvature is a
b.
bowing effect from edges to center, arcing
toward the rear of the machine. Check blade
curvature by placing a straightedge or string
across the corners of the blade and measuring
maximum deviation at center, 1/8 in. (3 mm)
maximum (TM 5-3805-261-10).
BLADE LIFT CYLINDER SOCKETS
INSPECTION.
Check socket (1) wear by lowering moldboard
to hard surface until ball seats firmly in upper
half of socket. Raise moldboard and measure
distance until ball seats in lower half of socket.
Maximum measured clearance should be less
than 0.040 in. (0.10 cm). Shim replacement or
removal may be necessary
(TM 5-3805-261-20).
