Correct, no movement up and down, just the whole drum front to back
The concrete weight at the top moves around 100mm front to back
I have to go out now and won't be back till later this afternoon so no great rush answer
I'll let you know how it goes
have a good Weekend
Just an update .
All the bolts are tight. There were a few bits of 'lint' in the filter with some threads but the blades could spin. I've removed these.
We'll do a wash later today but as long as the thing keeps washing (and I'm 100% sure the bearing is ok) I won't worry about it too much now.
Thanks help. Always nice to talk to someone who knows what they are doing and can install a little confidence in what I can do
