    Default 260 Spindle Assembly - Bearing Seals

    Hi everyone
    I am reinstalling the spindle on my 260 and have become a little confused in relation to the positioning of the aluminium bearing seals. These seals have a cutout in them, which I assumed was to allow oil in to the bearing. I currently have the cutout positioned such that oil can come in through the elbow oiler, and can exit using the smaller drain hole in the bottom of the bearing housing. With the seal set up like this any oil that I put into the oilers immediately drains out of the hole in the casting. As far as I can tell, the oil level will never reach the bearing at all, leading me to think that the seal may need to partially cover the drain hole? If anyone knows how the seals should be positioned in relation to the oil inlet and drain holes in the headstock casting of a 260 ATM, please will you let me know?

    Here is how I currently have the seal positioned: (Looking from the left, at the right hand side bearing seal)

    Is that really a drain hole?
    In this drawing from the maintenance manual it looks to be connected to the bearing space.

    Hi Nadroj, you are absolutely correct, I feel a bit of an idiot now. Had I looked at the headstock from the front I would have seen the hole which connects to the little basin in the outer cap. Thanks for answering a silly question in that case.
