I have a Yamaha wolverine 350 that a took to a local mechanic and it sat in his shop for 6 months and I said enough was enough, so I brought it home it the top end was off of it and I got it back in pieces, there are 2 top end purse that I cannot figure out. I know the piece that holds the baring in but I cannot figure out the piece of bolt with the nut and a flat head on the end of the threaded pieces, I watched a YouTube video and the guy mentioned the remaining of the 3 pieces a tensioner. Any help would be great.
