Motor Grader Carrier Reducer – Ratio, Spline and Housing Guide
This final-drive carrier reducer must be matched to the exact motor grader system. Confirm whether the record refers to a complete reducer, carrier or internal gear set. Similar-looking parts can use different internal or mounting details.
Ordering basis: Confirm axle application, reduction ratio, input and output splines, housing pilot and mounting pattern 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 application, reduction ratio, input and output splines, housing pilot and mounting pattern.
Diagnose the surrounding system
Inspect the mating components, fluid or mechanical condition and the original failure pattern. Confirm whether the record refers to a complete reducer, carrier or internal gear set. 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 final-drive carrier reducer be matched from a photograph?
A photograph helps, but axle application, reduction ratio, input and output splines, housing pilot and mounting pattern 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 application, reduction ratio, input and output splines, housing pilot and mounting pattern.
