i have a new eagle forged crank and a fluidampr copy dampner. i can slide the dampner on and off with not puller tool or installation tool. there does seem to be any play when i "wiggle" it, but something doesn't seem right with that. all the dampners i have ever taken off were tight and required install and removal tools. this one is snug, but i don't like how easily i can pull it off and on.

other posts about sheared off keys makes me nervous. what do you guys think. got it from ebay new from dirttrackthunder.com and prolly can't return if i wanted. does the fit have to be so tight it requires install/remove tools.

any help appreciated.

thanks,

mike
