Hi
Thought it worth sharing my little mod/salvage/repair to the lower pins on my 260 rear arms; After 1+1/2 hours trying to remove them, the external threads were beyond repair and the cotter pins needed drilling out, I then had the dilema of locating new pins
or making new (material grades etc became an issue) then a moment of inspiration resulted in a couple of hours on the lathe where the threads got parted off and the pins got drilled and tapped 3/8th (10mm) and some cap heads got screwed into the holes; the cotter pin holes got tapped out 1/2 inch (12mm) and a grub screw will now locate in the cotter pin slot of the pin to act as anti rotation, the lower arm also had a light reaming with an adjustable reamer to polish up the post removal burrs etc, the result is a serviced pair of pins that you can also pop a pin punch inside to the hole to tap them out again in the future, the cap heads secure the bush sleave and hey presto jobs a good'un.
You don't need a lathe to do this mod, a steady hand and a drill would do, drilling and tapping on the lathe just helps get things central and true.
All The best
