This should bring it into a gross alignment which will be fine tuned with feeler guages ? fingers crossed it will be close enough.
Thanks again for the response.
"Cheers" Gemini 34.
yes I have a prout 37 cat with a sonic mk1.
and yes increasing the adapter plate/bar thickness should do the trick.
getting exact alignment Is quite difficult but the flex coupling is quite forgiving!
best thing to do is to measure the gap from one side of the output flange to the input flange,and measure at 90degrees,,180 deg,270deg,and 360deg all should be equal if in alignment vertically and horizontally.
parallel misalignment is more difficult to correct but using a set square from the input flange (sonic) to output flange(gearbox) and turning 360 deg will show if the gearbox
needs moving up,down, left or right,then re check parallel alignment.
checking for parallel misalignment is best done first
