Q&A Section

Q1: When should I replace the swing pinion arm?

A: Replacement is necessary if you notice visible cracks in the steel, elongated (oval-shaped) pin holes, or if the blade exhibits excessive "play" or shaking during rotation that cannot be resolved by adjusting the circle shoes.

Q2: Does this part include the pins and bushings?

A: Typically, the 28350003661 refers to the arm itself. It is highly recommended to purchase new pins and grease seals simultaneously to ensure the entire linkage is tight and properly lubricated.

Q3: Is this part compatible with Volvo Motor Graders?

A: Since SDLG and Volvo share engineering platforms, this part may cross-reference with certain Volvo grader models (such as the G900 series). However, you must verify the specific part number in your Volvo manual before installation.
