Mild steel non-plated shafts rust and need to be replaced (shown on left). These missed an essential step to be HX6 (gold) passivation, suitable for installation (right). Non-plated shafts were mistaken for stainless shafts (right).
Mild steel non-plated shafts may show signs of rust, are highly magnetic, have blue discolouration from welding and do not have a part number on the lever arm. These must be replaced.
Stainless steel shafts will not show any signs of rust, have a lighter shine to them, are only lightly magnetic and have a part number visible on the lever. These do not need replacing.
HX6 passivated mild steel shafts are bright gold, show no signs of rusting, are highly magnetic and have no part number on the lever. These do not need replacing.
Tools needed for assessment and repair: needle nose pliers, small hammer, 4mm Allen key, ~150mm screw driver.
To assess the part number or replace shaft, Remove lock cover by unscrewing 4x M6 screws with a 4mm hex bit or Allen key.
Note: These are secured in place using Loctite, you will need to break the Loctite using an Allen key before fully removing with an impact driver.
