My local PIRTEK man had an inset collar thinggy to crimp the ferrule in his van. Not used very often except on some bob-cat stuff ( ?? forgive me if it wasn't that but the name sticks in the old memory cells). While not questioning the re-hosers in any way, but everyone having a set re-hosed should take the front or rear adapter thinggy with them to make sure that the new cone and especially the NUT fits into/onto the adapter thinggy* and screws down fully because while the first 4 or5 or so threads are OK, the nut can tighten up on the adapter. So just be fore-warned.

I didn't want to go into detail but you can overcome this by a bit judicious thread cleaning
*Andy, you loaned me a half decent M&F thread while I was writing up some notes ages ago.

That's a pretty good picture by Tim at minimail Mab and shows the differences between reality and the pictures. What would be even better would be a knackered unit set up in a lathe and sliced across the outer bulge joint. So that the top and bottom parts came apart and the guts could be pulled out. Anyone got a knackered unit to slice apart on the lathe?

Is this one knackered enough for you Peter?

Yep, that'll do nicely thanks. See you at Beaulieu! Do you have the broken off intake/outlet nozzle bit?

Hi. Does anyone know the nearest hydraulic fitting to the female end of the hydro hose? I believe the thread is 5/8 UNF with a dome mating surface of god knows what angle. JIC appears to use UNF, but 5/8 is not a standard size and the dome is a cone, so no use. 3/8 is the nearest size BSP but is too large and the wrong thread. What do the re-hosers use, the likes of those metioned earlier in the thread, there must something that will work. Displacer end seems simple with a threaded/tapped union, although 1/4BSP or NPT wouldn't leave much, so maybe 1/8BSP? Many thanks, Richard.

I've got the Gates hose end number somewhere Richard.

It has an O ring on the sealing face and although when looking at it, it doesn't inspire much confidence, I have been reliably informed that it works fine.

Will find number and let you know. :)

So is that the one the re-hosers use, or one you've heard works? Cheers
