Solution purchasers are entitled to rent installation tools from LN for the cost of shipping. Although I've borrowed an IMS Pro Tool Kit from a kind forum member to extract the old bearing, LN's $299 Supplemental Tool Kit is necessary to install the Solution's bearing. I can keep the kit for 30 days, but I'm holding off renting it until it's needed. I'm waiting now for a Ryobi cordless right-angle drill to get here. It's the perfect tool for working in tight spaces, such as creating a notch in the crankcase for the flange's oil fitting using a tungsten-carbide burr bit.
