Hi,
Just before Midges stopped play I was having a look at the air con condenser which I have to replace (along with the drier which is toast) and I wondered whether anyone knows what size the nuts are ?

initially 19mm seemed too small, and 20 seemed to fit, but quickly 20 started to slip and now even 19mm seems a bit slack.

I’m worried about rounding the nuts which appear to be aluminium (I’m sure there’s a good reason but it’s bloody annoying) so does anyone have any smart tips for getting these off safely ?

thanks again

badly-bitten Bob

Piece of wood and gentle tap with hammer

Hi,

I’m not sure I understand, do you mean to give the seized nut a tap ?

I’m sill a bit puzzled about the actual size of these nuts.
On the one I’ve attempted with a conventional spanner, a 19mm flare spanner seems to fit but then slipped on the nut and doesn’t want to go on in any other orientation. The lower nut seems to sit between 19 and 20 mm -3/4” would be 19.05mm but I’m really struggling with this :(
 
I seam to remember doing mine with a big adjustable spanner,
some times going for different flats can break the tight joint, grips tend to squash the nut on to the thread.
 
Extreme ,but in the past iv cut a slot in a ring spanner ,put over a pipe then used mole grips on the spanner to stop the ring bit:rolleyes: spreading ....:D,,it was a turbo oil feed pipe ,nut ;),,,,

Yep the tap can just shock it to help turn then as said adjustable spanner or small stilsons
 
And they’re off !
Some combination of 20mm, 19mm and 3/4” flare spanner’s and an adjustable wench.
The top nut was tough and a little ‘chewed’ but the bottom one (with the 20mm flare) was a dream.

moral of the story: spend £15 on the right tools rather than trash an expensive pipe !

-and ask for advice, obvs !

Thanks again, on to the next challenge !
