No, or maybe it is for the experts... but I learned a couple of things as mentioned above. I don't find that with the oil and filter threads. And also, I didn't realise that Dryseal threads were an actual standard. Dryseal seems a pointless standard to me anyway because 'to be safe' people...

BTW, welcome to the forum @neal boudreau. Too late now, but FWIW I discovered that these are available, about USD90 "The Fuel Bridge is a small, compact module that wires in-line between your fuel sending unit and your fuel gauge. It reads the resistance signal from your fuel sender, re-maps it...

It does happen :eek:. In this country due to imported equipment from different countries we get a mix of BSP and NPT, but most people assume the thread is BSP. In Canada a relative observed tradesmen regularly force-fitting NPT instrument connections into BSP threaded housings. :rolleyes: I...

A note for anyone else contemplating replacing their Kobato sender... sometimes there's a way to make a new (different resistance) sender work with an existing fuel gauge. Needs a little research and basic resistor and maybe capacitor soldering :-) Depends how you value your time.

Thanks I was curious to know if the BSPP and NPT were being asked to play with each other. They aren't, so I can relax :)

I'll be interested to hear how it works out. Which parts are BSP and which are NPT? Same tpi, but different thread forms I thought were not reliable for leak tightness, even with doping, in hydraulic pressure situations.

Seems to be OK here, 19 minutes after RCW's post. And thank you to the mods/Mr K too.

@Hugo Habicht is this what you mean? https://parts.theslshop.com/rubber-boot-2013300085/

O-rings? Where the hell did that come from? :) The deed's been done but if you have time to wander into a hydraulic services shop next time you are near one, ask to be shown around and shown piston and rod seals. .

Looks like your on the way to getting them fixed :) I'm estimating that a hydraulic shop would charge less than 50% of the price of the Kubota seals of comparable or better quality and you'd still have only one party to hold responsible. They would probably have the right seals on the shelf...

Why not use M16x1.5 instead? (For consistency, assuming that the rest of the loader/tractor is metric). Its a common enough thread used on Kubotas. If it is grade 8.8 I believe that it is more weldable/heat treatable than some ANSI higher tensile bolts (subject to confirmation by @torch whose...

Did an autopsy on what are probably the original ball joint boots from my tractor. They have a steel reinforcing ring bonded into the small hole, and the large hole rubber skirt is trapped in a swaged steel ring. The small hole reinforcement = boot less likely to open up and lose its seal when...

Thanks, hadn't paid any attention to the picture search. Will try it. Also interesting about the MB boots, I'd mainly been looking for Japanese 4X4 and light truck equivalents.

Internet slop is a thing on Aliexpress. Unbelievably useless search engine because shops put in irrelevant/unavailable products just to get you to their web page, then if the product is availalable the dimensions and descriptions often don't make sense. Most probably don't know what the...

I don't understand the reasoning in paragraph 1, but at least in para 2 if it breaks I doubt that anyone's going to get hurt so I'll leave it at that :)
