Many thanks

Using your skilz!

Check the manual, they usually have it listed in the back.

Thanks. Any tips on correct tool to use to remove it. Seems to be a very narrow gap for a spanner.

you call that narrow??????????????????????? try working on a worcester theres loads of room there

 

[DaveG]

A spanner is too thick to get under the housing. Do you use a specialised tool?

 

[zeebeedee]

I'd get that with my teeth!

grips

 

[DaveG]

Would you just use the grips on the housing itself. There appears to be a nut underneath but cant get in there.

 

[lame plumber]

just wait until you shear it off, then the problems begin

 

[DaveG]

What would you suggest then?
