Klargester BioDisc Radial Arm Replacement – Pathhead, Midlothian

Our Klargester BioDisc radial arm replacement in Pathhead, Midlothian was carried out as part of planned remedial work following a routine service. We identified severe corrosion that could have caused major mechanical failure if left untreated.

Why Radial Arms Matter

Radial arms connect the disc pack to the central shaft, ensuring smooth and aligned rotation. When corrosion takes hold, they can:

• Cause disc packs to shift out of alignment
• Put stress on the shaft and gearbox
• Lead to uneven rotation and mechanical breakdown

Routine inspections catch these issues early, saving costly repairs or full system replacements. For manufacturer guidance, see the Klargester BioDisc product page.

The Repair Process

This planned mechanical repair included:

• Stripping down the drive end
• Removing the damaged radial arms
• Installing new radial arms
• Realigning the disc packs
• Running functional tests to ensure smooth operation

The result was a perfectly aligned disc pack with zero stress on the drive assembly — eliminating the risk of imminent failure.
