I found myself with 2 DC01 Absolute+'s, so refurbished the less original one to sell it. All went well, until I came to test it when back together..
Right at the end there is an annoying squeak.
Just to test what the issue was, I removed the belt and brushroll
Squeak gone, so that means it's somethign to do with the brushroll...
So, out come the brushroll bearings (which I didnt grease as they span fine, this machine has had a few new parts on it in the not too distant past I think).
So, bearings apart, a quick squirt of

and back together, being careful to screw the baseplate down evenly, then I backed the screws off 1/4 a turn so it clamped and sealed, but didnt distort.
My assistant aided me in testing it afterwards
Job done! Went up for sale last night, 0% interest in it so far (but wasnt expecting much tbh, it's 'old innit'





(I kept the nice AB+ purple tools and the soleplate rubber...)
