Motor Grader Tilt Joint 380905958 – Fitment and Articulation Check
Part number 380905958 identifies a tilt joint listed for a motor grader linkage application. This joint must articulate through the machine’s working range while keeping its pins, bushes and mounting faces correctly aligned. Confirm the exact installation position and compare the removed joint before ordering.
Useful ordering evidence: photograph the complete installed linkage before removal, mark its orientation and send a clear image of the 380905958 reference. Include the grader model and serial number so the parts-book position can be checked.
Geometry controls fitment
Measure the centre distance between mounting bores, bore diameters, joint width and any offset between the connection planes. Also record pin length, retaining method and grease passage position. Similar-looking joints may differ in articulation angle or clearance around adjacent structure.

Inspection before replacement
Check pin and bore clearance at every pivot.
Inspect bushes for oval wear, scoring or rotation in the housing.
Look for cracks around welded or highly loaded sections.
Confirm grease reaches the bearing surfaces.
Inspect adjacent links, brackets and cylinder mounts for misalignment.
Installation and movement check
Support the linkage before removing pins. Clean bores and inspect them against the service limits rather than installing a new joint into an elongated mounting point. Use the specified pins, bushes and retainers, lubricate as required, and tighten fasteners to the machine procedure. Cycle the linkage slowly through its permitted range and check for binding or interference.

FAQ
Is 380905958 enough to confirm the joint?
It is the primary reference, but the machine serial number, installation position and physical dimensions should also be checked.
Can only the joint be replaced when a bore is worn?
Inspect pins, bushes and mounting brackets. A new joint may develop play quickly if surrounding bores are outside limits.
What can cause restricted movement?
Misalignment, incorrect pin dimensions, seized bushes, damaged brackets or insufficient clearance may restrict articulation.
Should the linkage be greased before testing?
Follow the machine lubrication procedure and confirm that grease reaches the working surfaces before operation.
Compatibility note: Final selection requires 380905958, machine identity, linkage position and measured joint geometry.</p
