This evening I managed to remove the link arms and lift rods from Freida. I’ve spent days soaking the seized clevis pins and linkage knuckles in WD40 and trying to club them out with my trusty 3lb ball pein, to no avail.
With no heat source available to make the knuckles glow before smacking the rusted pins out, I decided that the only option available was to cut through the pin with a cutting blade on an angle grinder, in the gap between the knuckle and the lift arm fork.
After doing so I discarded the knuckles, lift rod and link arms as they have had it. Although the coffee grinder is still good.
Pics to follow, as I’ve yet to requisition a camera.
