Motor Grader Brake Drum – Diameter, Width and Wear Guide
This brake drum must be matched to the exact motor grader system. Measure the friction surface and hub interface; do not assume drums are interchangeable by outside appearance. Similar-looking parts can use different internal or mounting details.
Ordering basis: Confirm axle position, inside diameter, braking width, pilot, bolt pattern and wear limit before ordering.
Information buyers should provide
Machine model, serial number and installed location.
All casting, stamped or label numbers.
Clear photographs of every connection and mounting face.
Measurements for axle position, inside diameter, braking width, pilot, bolt pattern and wear limit.
Diagnose the surrounding system
Inspect the mating components, fluid or mechanical condition and the original failure pattern. Measure the friction surface and hub interface; do not assume drums are interchangeable by outside appearance. Replacing the part without correcting contamination, misalignment or adjustment faults can cause repeat damage.
Installation and functional verification
Keep interfaces clean, compare the old and replacement parts side by side and follow the machine service procedure. After installation, check leakage, free movement, noise, temperature and the related machine function under controlled conditions.

FAQ
Can this brake drum be matched from a photograph?
A photograph helps, but axle position, inside diameter, braking width, pilot, bolt pattern and wear limit must also be verified.
What should be inspected before installation?
Check mating parts, mounting faces, lines or fasteners and the cause of the original failure.
Why are unverified model claims avoided?
The original record does not contain enough evidence to prove a specific model fitment.
Compatibility note: Final selection requires axle position, inside diameter, braking width, pilot, bolt pattern and wear limit.
