Looking for service bolt and nut to repair equipment shaft couplers

My front shaft is knocking and I'm looking for the bolt and nut to remove the front drive pulley Can anyone help me out by loaning me the tool. Or where I can get one? Thanks Bruce

If you are looking for the affair described in the FSM, I think it's just a standard bolt and nut, screwed into the end of the SADS so that you can get a wrench on it and turn the engine over to access the bolts on the front pulley of the engine. I've never done this. Instead, I use a strap wrench on the SADS directly. I often have to wipe dirt and grease off of it first so that the rubber strap of my cheap strap wrench can get a grip, but otherwise haven't had an issue with this approach.
The bolts you need to remove on the front end of the SADS are the three that hold the front bearing housing onto the accessory drive housing. These can be removed with conventional tools, although the upper two can be a bit of a challenge to get to.
