Olympia SM3/SM4 Typewriter Frame Mount Bushing

Restore smooth, consistent operation to your Olympia SM3 and SM4 typewriters with this newly made set of frame mount bushings, a critical replacement part for maintaining proper internal alignment and function.

These bushings are designed specifically for the Olympia SM3 and SM4 series, where the original frame mounts act as key isolation points between the internal carriage assembly and the outer chassis. Over time—often after years or decades—these bushings harden, compress, or disintegrate, allowing the internal mechanism to shift and rub against the frame, leading to uneven key action, increased friction, and inconsistent typing performance.

Each bushing is crafted from durable, flexible TPU material, restoring the correct spacing and cushioning between components. This helps eliminate metal-on-frame contact, reduces vibration, and brings back the smooth, precise feel these machines are known for.

Installation is simple and straightforward, making it an easy but highly impactful maintenance upgrade that can dramatically improve overall performance.

Proudly made in Canada, this set is a reliable restoration essential for collectors, technicians, and everyday users of Olympia SM3 and SM4 typewriters, helping preserve both function and longevity of the machine.
