Anthony, …..you can do the swap on engine. Take note of the eccentric clocking on each side. Take pictures before removing any parts. Remove the rear driver’s rod bolts. Remove the eccentric screw, wiggle the eccentric loose, and don’t lose track of the sleeve. Work one side at a time. With the eccentric out of the way, and the rear rod bolt out, swing the connecting rod around and out of the way. No further dismantle is required to access the driver fastener. Be mindful of rod bushings in the rods, they like to slip out & disappear into the night …….the driver screw is Allen head, and the factory loved to use a lot of loctite!!….find a wrench that fits perfectly snug!!….better if you have to slighty tap it in place!!….it will round out in a heartbeat!!…….before you attempt to loosen the fastener, stick the tip of a clean soldering iron on the head of the screw for a few good minutes!!…this will help loosen the loctite ……the wheel will come off, and you’ll note the D shape axle, ….reverse order for install, then do the other side ……no need to put loctite on it going back,….just make fastener checks of those screws as part of your routine maintenance program….
