Bump?? Please - How to remove vacuum pump adaptor off camshaft?

 

I'm doing a teardown in preparation to do a valve job on my wife's 2013 S60 T5. I'm using the VIDA for advice, (which I'm discovering is a disappointment). I'm ready to lock the camshafts, and I've removed the vacuum pump off the exhaust side. (VIDA doesn't even show a vacuum pump as an option.) To my surprise I find, what I think is an adaptor on the end of the shaft held on with a T30 screw which I cannot budge. (Plus the camshaft wants to rotate.) How does one remove that to expose the expected notched end of the camshaft? Any advice on this would be greatly appreciated.

Those T30 usually have to have the screw heads drilled off. Once the head is drilled off the shaft is easily removed. Obviously, you'll need a replacement screw upon reassembly.

I've even tried impact wrenches on those screws and the Torx bit broke.

 

qaz;

That's really good intel which saves me the grief in finding out the hard way! I knew drilling it was the last resort, but knowing this puts my mind at ease. I'm grateful for your kindness in these times where nothing seems to come easy.

 

I am not sure how eventually you removed that screw, but I was able to remove it with a T30 Torx, tap the T30 torx deeper/secure and use a long break bar attached to the Torx, then the screw came easily. How did you remove the vacuum pump adaptor that has a vertical notch on it in your picture? Thanks,
