Motor Grader Pin – Position and Dimensional Identification
This product is listed as a general motor grader pin without a confirmed part number. A safe match begins with the exact installation position, because a grader contains multiple pins with similar diameters but different lengths, shoulders and retainers.
How to describe the required pin
| Identification | Details |
|---|
| Position | Assembly name, machine side, joint function and annotated photo |
| Body | Diameter at multiple points, working length, total length and steps |
| Ends | Thread, cross-hole, groove, keeper plate or bolt-retention geometry |
| Lubrication | Grease fitting, axial drilling, cross drilling and groove location |
| Mating joint | Bushing, bracket width, bore size and evidence of ovality |
What creates repeat pin wear?
Possible causes include dry lubrication, misalignment, worn bushings, an oval housing, incorrect hardness or excessive side load. Measure the joint as a system instead of replacing the most visibly worn part only.
Installation scenario
Support the connected structure before removing a loaded pin. Clean and align bores without forcing the replacement. Confirm retainer engagement and grease flow after assembly, then inspect the joint through controlled movement.

FAQ
Can a general pin be selected from diameter alone?
No. Position, length, ends, lubrication and mating parts must also match.
Should the bushing be measured after pin removal?
Yes. Bore wear may account for much of the clearance.
Can a worn pin be used as the original dimension?
Use unworn zones or verified service data because loaded sections may be undersized.
Compatibility note: No specific model is claimed; confirm the exact joint and full geometry.
