I’m a bit new to this and have a question about the drive sprocket change. I believe I have all the necessary tools (fixation for the starter gear and sprocket), but I’m seeing in the repair manual that they say to use Loctite 648 on the nut. I’m also seeing that 648 requires heat to loosen. Will i need to heat the nut to get it loose?
You may not have to correct tools. I assume you have used the fixation tool for the starter gear to remove the nut that holds the clutch drum on. Next, place the fixation tool for the sprocket in a vice or fasten it to a heavy work surface. This where you might not have the correct tool. The socket to remove the nut that holds the sprocket, believe it was an inch and a half, needs to be modified. Because the nut is so thin, the rounded opening of the socket needs to be cut flat so it engages the nut completely. Once you’ve done that and use a breaker bar, you should have no problem removing the nut without heat.
