Toro has just discontinued it so I decided to make up my own. Since I can't easily cut the slots for the E-clips, I decided to just use cotter pins and washers. I used all 316 stainless steel since I had some left over scraps at work. Here is the pin cut and drilled. Here is the mounting plate cut and drilled sitting beside the pin. All welded up. This is my pin and a worn out OEM pin for comparison. Here are some more comparisons between the two. That is a used nyliner bushing sitting between the washers as if the block was there with the bushing installed into it. Since I have 4 520's, I made up 4 pins. I am unsure if a horizontal or vertical pin placement is better or easier to use so I made 2 of each. I hope there is enough room to install the cotter pins. Here are the plans that I drew up. Wheel Horse motion control pivot.pdf My writing is not the best. From the center of the first hole to the inside edge of the mounting plate is .77".

WVHillbilly520H 10,369 #2 Posted January 10, 2018 Nice work, when I needed a "C"/"E" clip groove cut at work, I would get a piece of HSS tool stock 3/32" thickness and grind my own "slitting"/"parting" tool close to the width I needed then trial and error till I get said clip to fit, as a lot of machines at work used clips vs hair/cotter pins in their shafting anything from Thomson, drill rod, A2/A6 tool steels, 4100 series prehard ect and it cut it, Jeff.
