Additional 727 sprag oil supply hole, yes or no?
Hi Gents
I’m putting together a rollerised 727, I’ve seen some people drill a small hole 1/8”, in the back of the case in the return line feed to add extra lubrication to the sprag, as I’m installing a roller rear support there is a seal on the inside of the support to help keep the bearing lubricated on the output shaft, this seal will effectively minimise oiling to the sprag so those who have fitted rollerised rear supports, did you drill the hole???
