Thanks, Chris. I was really worried as to whether or not it might be to something critical. Hopefully it's not to the hydraulic pump or something.... 
I am not sure if it's a 1/4 or 5/16 bolt as I am not at home, but the bolt IS. What happened is I was doing this Sunday evening, and I just wiped it off once I got it out of there ( difficult ), and put it in the house, as I had to get the fluids back in the thing, and get it going before dark. I live on the Olympic Peninsula, near Port Angeles, but work in Seattle, so I stay over there during the week in my trailer. I left Monday morning to head over to Seattle to work for the week. -Due to all of this, I never had time to give it more than a quick look as I wiped it off. I'll have my son check it tonight. It HAS TO BE a 1/4 or 5/16....
If it is from clutch fork, how many are in there if all are present? I'd hate to have only one bolt holding the thing together....
 *****UPDATE***** My son measured the bolt diam. as I'm typing this, and it's 5/16.
Thanks for your time!
