Thanks Again for the info Torch... I feel a bit more comfortable now armed with that info... seems that based on that rule of thumb the bucket is sitting in roughly the right place relative to the front wheel... see pics attached
20 inches by my calculations is 508mm and the back of the bucket sits approx 1050mm from the rear of the front tyre

Not sure if I have a different size Hydraulic Transmission Oil filler cap??? But mine doesn't seem to be 1/2 inch. It seems to be more like 20.5mm (13/16" or am i measuring it wrong?

Ok, it must have been the perspective in the pics, it just looked further forward than it was. But the tape don't lie, so you're golden there.

1/2" NPT is the standard tapered thread for 1/2" pipe (National Pipe Thread). Pipe is sized by nominal ID (tube is sized by nominal OD) so the OD is ) .804", a little over 21mm.

Since pipe thread is tapered, running the tap in a little deeper will open up the thread and let the cap wind in further.

Taranakiguy, that is an interesting steel tape measure. Just don't see them is these parts!

You're doing a nice job. Nothing much more satisfying then building something yourself that does what you want, the way you want and save a couple of thousand dollars!

Yes your measuring it wrong, 1/2" is the inside pipe measurement, and yes that is a 1/2" NPT fitting.

Thanks D2Cat...
I really enjoy learning by doing, so this little Kubota has been a great classroom. At some point I'd love to strip her right back and freshen her up with new paint etc... but that might have to wait until I've built a decent workshop!

Ha.. just assumed that this would be the sort of thing that lying around in every toolbox in the world?

Thanks Torch and Wolfman... I obviously have got a lot to learn... so thank you yet again for the advice...
I have ordered a 1/2" NPT tap so hopefully that will do the trick

Default Re: Fabricating Loader Sub Frame for B7100 HST

Well the Loader Legs seem to function as intended... just need to get some paint on them... but as you can see with the water on the bucket... it's been a bit wet to paint outside (might need to hook her back up and move it under cover)

Question...
Is it normal practice to somehow anchor the bucket when trying to back the tractor out from under the loader? I'm assuming it must be, as mine was really tightly bedded onto the subframe and wouldn't budge without the persuasion of a block of wood and a large hammer.

So I'm wondering in future if it would be worthwhile perhaps tethering the bucket to a solid post (or something similar) to anchor the loader in the hope that I can then simply reverse the tractor (once removing the locking pins) to slide the tractor out from under the loader...

(don't think the wife wife was too impressed that I asked her to stand in the bucket and act as said anchor!)

Maybe you just have the mounting brackets built to a real close tolerance! Maybe a bit of wear from removing the loader will make it a bit easier. The should actually be free when all the pins holding it are removed and the weight is off the loader towers.

All my loaders have the loader stands further forward, acts as a seesaw, curl bucket down, set stands, curl bucket up and the back of the loader pops up to clear the mounts, disconnect the loader hydraulics and away ya go.
The old Kubota loaders used bars / stands off the sides of the bucket, to allow it to lift the back of the loader up then there were stands like yours too hold up the back legs.
