WCMatt Posted September 20, 2018 Share Posted September 20, 2018 I have a ferret Mk. 1/2 that I'm working on. Would like to remove the rubber lines that are plugged into the oil cooler so that I can remove the cooler itself & straighten all of the little "hoops". Anyone know what size spanner would fit the rubber hoses? All of the fasteners on my ferret seem to be SAE and I've tried a couple of different sized wrenches on there but they are either a lose fit or won't go on at all (wonder if they might be metric?). Thanks. Regards, Matt Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted September 20, 2018 Share Posted September 20, 2018 Can you get a caliper on to the flats to measure? They could be BSP thread or the American pipe thread (can’t remember its name, I’ll look an idiot if it’s APT). Quote Link to comment Share on other sites More sharing options...
David Herbert Posted September 20, 2018 Share Posted September 20, 2018 This is why god gave us adjustable spanners (but not Stilsons !). 😁 David Quote Link to comment Share on other sites More sharing options...

I've seen them round off the flat corners of bolts/nuts before. So let's not go there....... Matt Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted September 20, 2018 Share Posted September 20, 2018 I have done that job numerous times but do not recall the spanner size, but if you cannot find an A/F spanner to fit then you will find it is a Whitworth (BSW) spanner size as I think the pipe unions are British Standard Pipe thread. Certainly will not be Metric. Quote Link to comment Share on other sites More sharing options...
sexton Posted September 21, 2018 Share Posted September 21, 2018 Matt, adjustable spanners can cause problems on smaller stuff but a good quality one will work no problem on those larger union nuts. Try it. Malcolm Quote Link to comment Share on other sites More sharing options...
