[Karsue]

Hi There,
On the spindle of head 1 at the spindle nose the bearings are damaged.
I dismanteled and taken out the spindle cylinder but I can not take out the bearing at the front of spindle (2 Angular contact bearings & 1 roller bearing).
I appreciate any recomendation and help with this problem and I need also some tools to buy such as oven or mandrill or any other neccessary tools to change the bearings at this spindle.
Thank you.
