Crankshaft distortion inspection tools

Hi Rusty,

I’m not sure where you live, but many service centers will rent these items out. Give one nearest you a call.

East TN, but I'm not sure what service centers are around.  If the pistons can be stopped at any position, I can make my own tools for less than shipping a rented tool, then I'd have them if ever needed again.  I'll be putting the engine on a test stand for a while for an upcoming project, so no huge hurry.  Maybe I'll even stumble across a used kit.

I made a piston stopper to check the crank phasing on an engine and it seemed to work out OK and give sensible results. Here is a diagram of what I made.

That's outstanding Kevin.  Thanks very much!

Hi Rusty

the piston stop has to be mid stroke.  As the crank angle to the piston is at it fully extended or retracted points the travel is very low so hard to know what the degree difference there is.  Mid stroke the crank piston stop rod is going to show the differences more accurately.  Follow the process in the heavy maintenance manual.  Do not forget to check the crankshaft run out on the nose of the engine as well.  Do this with at least one spark plug removed from each cylinder to stop the influence of compression on the readings.  

Cheers
