Here's my "crank holding tool" in action. The 16" adjustable wrench sits perfectly on the main body frame.
Here's the rear cam sprocket bolt wrench I made as I disassembled and assembled this several times prior to getting everything running.
Rothenbacher crankshaft timing sprocket. I purchased this for $7.00 as a spare but did not use it. I know his reputation but I have gotten some good useable products from him and this sprocket looks very good. I will likely use it on my 2.0 once I get around to that project.
