This may be a repost so forgive me if it is, but I've never seen it here. Pelican Parts has an awesome tech article write up and pictures on IMS bearing replacement using the LN Engineering retrofit kit. Also included is general engine rebuild ect. A lot of people talk about the IMS and issues surrounding it, but rarely do you see pictures and a step by step guide like this.
