Fiat Allis 10 Tilt Cylinder Hose Fittings

I've had a log get serious with the tilt hoses on ours, including wrecking one of the fittings to the pipes beside the radiator. It has been "farmerised" and the one good one is a JIC flare that appears to have had the nut expanded. And it has been sealing on the outer rim of the flare. The screw nipple feels like it should seal in the centre of the nipple - I can't really get a look.

The parts book doesn't give fittings or type/dimension - only a made-up hose.

So I have 14 tpi, somewhat bigger than an SAE nut, not flared and seals in the centre of the nipple by the feel.

The nipple is 22.5 mm diameter over the threads.

5/8 BSP looks a possibility? Apparently common on European machinery. And our supplier who would know is closed for Xmas/New Year.

Anyone got any more info?

TIA

Looks like we have an answer.

Seems it is 5/8 inch BSP. Local machinery dealer has never sold one. They're trying to find if that to screw-in 1'2 inch hose fittings are available.

Fall back looks like a 5/8 inch BSF nut silver soldered to a JIC nipple - which is what the rest is "farmerised " to.

We had to build them.

Nut is actually 7/8 inch UNF

So you're all fixed up now? I used to have a FL9 myself, good machine but this is where I got stumped as well. I needed a hydraulic hose for it. It seemed impossible to get. Thanks to a very helpful guy at a general industrial supply place, he carefully salvaged the old fittings and put on a new hose. It was a real wake up call regarding these Italian made machines... not necessarily fast turn around repairs when you're in a bind.

Big problem with this was the "farmerising". If it had been standard I could probably have bought a hose assembly.

We actually have pretty good supply of Fiat parts, even from Italy where there seem to plenty still available. Delivery on smaller items about a week. I don't understand why you people in US have problems.

Back in action but it wasn't that simple.

The nut used is 7/8" UNF not 5/8". The unobtainable BSP fitting is 5/8".

So we silver soldered JIC fittings to 2 nuts at the dealer's place in town (just next door - 150 km away)and they wouldn't screw on when I got them back to the dozer. So I bit the bullet and took the pipe assembly out, which turned out to be not so bad of a job. Then the plan was to cut the Fiat nipple end off and silver solder the JIC on. I was out of gas so talked to a neighbour who deals in things like this. He thread gauged it and decided that the nipple had been expanded by the BSP fitting. The pipe assembly is paired so no room to get a die on the threads. So he heated and bent the pipes one at a time, worked the appropriate die on and redid the threads. Bent the pipes back and Bob's your uncle.

I've just done around 5 hours pushing mulga as drought fodder for cattle and no leaks
