Buderus Tie Rod 5128020

This is a Buderus tie rod with an M16 thread and a 1520 mm length, supplied under part number 5128020. It is a threaded tensioning component used to draw and hold the boiler assembly together on Buderus G615 and Ge615 appliances. The rod takes the clamping load across the boiler body, so correct thread form and length are essential to the assembly.

• Visible corrosion, pitting or thinning along the rod shank
• Damaged, crossed or flattened threads that will not run freely on the nut
• Rod bent or bowed, so it will not seat squarely through the boiler body
• Stretching or elongation, causing it to lose clamping tension on reassembly
• Seized or snapped rod, typically found when stripping the boiler down for service

• Confirm the existing rod is M16 and measures 1520 mm, as thread and length vary between models
• Check the appliance data plate against the G615 or Ge615 570 kW to 1200 kW range
• Establish how many rods the assembly requires before ordering
• Inspect nuts and washers at the same time, as they are usually disturbed during removal
