Whats your worst idea: half baked, semi legit, embarrassed to ask? Post em up for a laugh...or a raised eyebrow?
1. Floater piston pin retention: press pin piston in floater rod. Same pin, just a bushed rod and no circlip grooves in the pistons, right? How about putting a cotter pin in the piston pin just outside the rods bushing? It would be inside the piston, and would prevent the pin from moving either direction. Now how would you make the cotter pin last, remain in position, or would it be an issue? Would the pin be weakened by the small hole?
