Bryan's post got me thinking. I am rebuilding a 540 ND and I am replacing the 2 piece cam with the one piece cam. I also know that the WD's have a different prop gov. ratio than the ND's.
I am now wondering if the difference in ratio comes via the gear on the cam or the driven gear on the idler shaft. I knew that Lyc recommended a straight swap from the 2 piece to 1 piece, so I assumed the ratio change must be coming from the different driven gear between models. I also knew that the parts collection on the idler shaft is different and that seemed to support my speculation.
Can anyone confirm that my logic is correct here? I don'[t have the one piece cam in my possession yet to compare the two gears.
Thanks,
Larry
