Installing the back case bolt

There is a case stud (3/8") that helps hold the back of the engine together. However, this bolt is under the camshaft gear. If it was not a stud, then your would have a bolt that would have had to been put in before you put the halves together just like the front main bolts. There is no orings for this since it's on the inside of the engine. Install the washer over the stud sticking out and then install the castle nut. I have a boxed eng wrench with an offset that I thinned down around the box eng. This helps it get around the nut and case. It's a tight fit in there. Get the nut tightened down and torqued and see where you hole is lined up. You can fudge a little on the torque if need be to line up the nut. Another method is to add a thin washer under the nut if needed. A thin washer was supplied in the kit but it ended up being too much and I only had abotu 3/4 of the hole visible. It says to safety wire this nut after it's torqued but we used a cotter key. It's tough to bend the tangs up but it can be done. We then safety wire the head of the cotter key over to the safety wire post next to the cam. The safety wire keeps tension of the cotter key and it also keeps the nut from rotating. This is an old trick to make it easier to get at all of that. IT'S A REAL BITCH TRYING TO SAFETY THE CASTLE NUT IN THIS TIGHT CONFINES. This other way is legal and it is flying around all over the place in the airlines. Make sure you get all of the safety wire clippings out of the assy case area and vacuum up any shavings DON'T BLOW THEM OUT.
