Valve Adjustment
The valve adjustment just took about 6-7 hours with the help of Derek. The most difficult part was pressing down on the lower rocker arm to remove the closing shims. The spring tension is high, so to press down on the rocker arm while removing/reinstalling the moon shims definitely needed the help of two people.
We ran into one problem removing the closing shim on the horizontal intake cylinder. the top of the valve had expanded a few ten thousands of an inch. Also the closing shim was so pounded metal had rolled into the inside of the shim making it difficult to pull out. So we fashioned a tool using a tie rod tool, 16mm hex, and a plastic bottle cap. it provided just the right slow incremental forced needed to pull the shim out.
Installing the new shim on this same valve also got stuck. So the inside of the shim needed to be sanded with some 400 grit.
Measuring and calculation was another daunting task. Measuring the closing shims would have been much faster using an adapter no longer produced, so hunting it down will be interesting. Another trick is to use a washer (or opening shim) to use as a constant additive number, but provide a much easier time to measure. mm to inches was also a bitch conversion. Overall it was the first time and the learning curve was steep. Thank goodness for Derek's help.
