I have a RD-7402 and its missing the o-ring that seals near head of the pivot bolt.
I tried a #10 11/16ODx1/2IDx3/32 and it seems too thick.
Any suggestions as to the right replacement and where to get?
Can I just run without it?
There is an entire pivot bolt assembly on the bay, but thats like $40, and take a while to get here.
Any help is greatly appreciated!
