Loose screws in Canon Zoom lens EF 100 400mm 1:4.5-5.6 L IS DISASSEMBLE ONLY

This Canon zoom lens 100-400mm 1:4.5-5.6 L IS,
had many loose screws and there was also 2 broken nylon COLLARS
in the front zoom section, so it could not work.
And the focus could not work proper, simply
because of 3 loose screw that hold's the zoom
collars in place.
All, because of poor screw thread lock.
The broken Nylon parts where lying around in the lens
But luckyli the parts has not broken the lens.
I din't find any spare parts for this lens.
So I made 2 collars from a good quality nylon nozzle
from a hard nylon bottle, with the same diameter,
and then the lens came back to life and works perfect again.
