Help-Mouse ate my fujitsu split system head aircon electronics

Good night. This thread will be closed tomorrow.

Why not, surely Toyota have manuals and all the tools required, how hard can it be?

Cheers, Jack

Aircon installation and repairs is not my trade and it will never be. Other aircon mechanics can ruin your reputation.

I have seen all sorts of dodgy work in old cars.

Good night

That is exactly why many people have a problem with what you say, other aircon mechanics CANNOT ruin MY reputation, only their own

What were you expecting?
My first vac pump was home made, an electric motor and a pump on a frame with a belt between them, nothing flash but it did the job.
As long as it is rated it doesn't matter what it looks like.
Did he have a name brand drill or a GMC, and would it have made a difference to the holes he drilled?

I was expecting better equipment from a 15+ years installer. Anyways I have learnt my lesson in life.

No, actually the other thread will be closed. Can someone answer my question - is it possible to use a torque wrench on a flare nut?

So what is in your toolbox at work, all highly polished shiny Snap On tools or do you have the odd rusty spanner in there?
Heaven forbid a customer should see you using a cheap soldering iron

Bog?

Goof morning Mick,

Actually Rothenberger have recently released a set of torque wrenches specifically for split system installs. The heads range from 17mm to 29mm inclusive and there are 6 different sized heads. The torque can be controlled from 0 to 75Nm which is the maximum required for 5/8 nuts. I purchased them late last year and they're absolutely great to use. Very easy and no problems.

Just on a side note in regards to a statement made by Learner, who claims that in regards to torque settings there is no room for inaccuracies? Can you please explain to me then why even in the Fujitsu manual itself the torque settings are within a range and not an exact figure? For example, the 5/8 setting recommends between 65-75Nm. Thats a 15% variation. Similar advice is given in the manual for all sized flares also.

I would accept 15% variation. Not 50%-75% variation

You have purchased torque wrenches and are happy to use them. You are not set in your ways like the older generation of aircon techs.

I would be happy to use your services for split system installations

If I was him, I would be very wary of such an offer.

Thanks for that learner but the thing is that there is no doubt many of these posters have a heap more experience than I do. Ive been in the trade since i was growing up with my father but officially 10 years including my apprenticeship and running my company. And I am sure that they would be able to 'feel' the correct torque required a lot quicker than I would be able to set them on the wrench. And for your comfort it is not actually possible to vary much above the 15% variation in the tightening of the flares without actually noticing the over tightening and cracking of the flare.

Goof morning Mick..............

And a very goof evening to you exotiic.
Interesting about the torque wrenches, I'll have to do a google and seen if I can find a pic. I can't quite picture them, I assume it's a flare nut spanner with a tension indicating device built into the shaft/handle, rather than a wrench that you can put some sort of socket onto. So before Rothenberger released theirs were there any on the market, or any other way of measuring torque on a flare nut?
