I don’t think it was installed by hand. Is there a specialist tool which should have been used? The fork is a couple years old so might have become misshaped slightly.
Assuming it was hammered on and wouldn’t go any further, is there anything to worry about re it not being fully seated? Was a FSA headset btw.
Just to add, I did catch him hammering the headset with a wooden brush handle and hammer to get the headset “seated” before using the press. Apparently it would go on due to too much paint on head tube.
Not sure how much I can trust this LBS..?
