Beogram 4004 (5526): Installation of New Transport Lock Bushings

I vacuumed the enclosure, and then it was time to install the new 3D printed bushings:
Each bushing has two parts, one to be inserted from each side of the lock orifice. Like all parts featured on this blog they are available to other B&O enthusiasts. Order them directly via the Beolover Shapeways store. Six parts are needed for all three locks. This shows the lower part of the left lock:
And with the sub-chassis outfitted with a new bushing installed:
I also did this for the other two locks and then I replaced the top halves of the locks:
Now this Beogram can be shipped again without fear for damage due to loose transport locks.
