PM previously sent: oiler bolt torque, there is one but for the life of me I can't remember it as I haven't used it for some time. Cain at wolf might state it in his fitting instructions but I have always found you can tighten them by hand very effectively as the threading is long and will take more punishment than you are likely to give it. I use a standard spanner and tighten it as hard as I can and have never had a problem! If I can lay my hands on my old note book I'll look it up for you.
