Perske Spindle repair

Hello All,

I am in the process of rebuilding my CNC Router Spindle Perske VS 60.11.2.
I am not able to remove the front bearing from the housing.
There is a front shroud which is fixed before the bearing.
I am not sure if it is slide fit or threaded to the shaft.
I have tried heating the shroud and gentle hits with a rubber mallet. It did not budge.
Haven't used a puller yet.
Does any one have a drawing of the spindle?
Attached a few photos for reference.
Thank you,

Antony.
