Motor Grader Shaft – Interface Measurement and Fitment Guide
This listing describes a motor grader shaft without a confirmed part number. The shaft must therefore be identified by its function and every mating interface, not by a broad product name.
Which measurements are needed?
| Area | Record |
|---|
| Location | Assembly name, installation position and rotation relationship |
| Journals | Diameter, length, bearing or seal contact and surface condition |
| Splines/gears | Tooth count, major/minor diameter, working length and mating component |
| Ends | Thread, keyway, groove, flange, pilot and retention method |
| Overall | Total length and shoulder-to-shoulder distances |
How should a worn shaft be measured?
Measure unworn reference sections where possible. A seal groove or bearing track can be smaller than the original diameter. Check runout and inspect transitions for cracks, fretting or heat discoloration. Send photographs beside a scale and include the installed assembly.
Customer decision point
If a part number cannot be recovered, do not approve fitment from one diameter. A shaft can share the same overall length with another version but use different spline count, shoulder position or lubrication path.

FAQ
Can the shaft be matched from overall length?
No. Journals, splines, shoulders and end features must also match.
Why provide the mating parts?
They reveal the required spline, bearing, seal and retention interfaces.
Can a worn journal be used as the nominal size?
Not reliably. Measure an unworn section or use verified service data.
Compatibility note: This page does not claim a specific model; confirm the complete interface set before ordering.
