SINOMACH 732T Grader Blade and Side Blade 730-81-A11A10 / 730-81-B11A10
Part references 730-81-A11A10 and 730-81-B11A10 are listed for grader blade or side-blade positions on the SINOMACH 732T motor grader. Correct identification depends on more than the machine model. Confirm which edge is being replaced, its overall dimensions, hole arrangement, thickness and working profile.
Ordering evidence: Send a full photograph of the installed blade, a close view of any stamped number and a measurement photo showing the hole spacing. This helps distinguish a main cutting edge from a shorter side or end section.
Identify the exact blade position
The two references should not be treated as interchangeable without checking the original part. A centre cutting edge and a side blade can differ in length, hole count, countersink direction and wear profile. Match 730-81-A11A10 or 730-81-B11A10 to the removed component and confirm left, right or centre position where the parts book makes that distinction.

Wear patterns that matter
Uneven edge loss can reduce grading accuracy and increase the effort needed to maintain a clean windrow or finished surface. Rounded corners, elongated bolt holes, cracking around fasteners and a tapered edge are useful inspection points. Uneven wear may also indicate incorrect moldboard angle, loose hardware or alignment issues, so assess the blade together with its mounting surface.
Measurements to send before quotation
Overall length, width and thickness of the removed blade.
Hole count, centre-to-centre spacing and distance from each end.
Hole diameter and whether the holes are countersunk or square.
Photographs of the working edge, back face and both ends.
Readable 730-81-A11A10 or 730-81-B11A10 marking, if present.
SINOMACH 732T serial plate and exact blade position on the moldboard.
Installation and service considerations
Park and support the grader according to the service procedure before working around the moldboard. A worn edge is heavy and can shift when the final fasteners are removed. Clean the mounting face, inspect it for distortion, and replace damaged fastening hardware only with the specified grade. Tighten in the machine sequence and do not force a mismatched hole pattern into alignment.
After installation, cycle the moldboard through its permitted positions and check clearance. A controlled inspection after initial use can reveal loose hardware or abnormal contact early.

FAQ
Are 730-81-A11A10 and 730-81-B11A10 the same blade?
No assumption should be made from similar numbering. Confirm each reference, position and dimensions against the original component.
Can the blade be ordered from the 732T model alone?
The model is a starting point, but blade position, dimensions, hole layout and machine serial number should also be checked.
Why is countersink direction important?
The fastener head must seat correctly and remain protected from the working surface. An incorrect hole form or direction can prevent proper seating.
What else should be inspected during replacement?
Inspect the moldboard mounting face, bolts, nuts, washers, hole condition and adjacent side hardware for wear or distortion.
Compatibility note: Final selection should use the original reference, measured geometry, blade position and SINOMACH 732T serial information.
