I found a bolt that had been snaped off in the bottom of my 98 863 when I was cleaning out the oil and dirt under the cab I traced it to the hyd pump assy that attaches it to the frame,right side,it looks like the only one that hold that side,the hole in the frame is kind of a ovel shape looks like it is made that way, got the broken bolt out by welding an extention on a drill bit and an easyout, going through the right side cover, when I put a new bolt in and tightened it up the plate between the pump and pump assy drips oil, take the bolt out and it stops dripping,looks like its held on by 4 torque bit bolts cant check if these bolts are loose unless take pump off, or is there suppose to be a thin shim between pump assy and frame.
