Odds are that is the one and only revision. Dan

I have tons of time so no need to worry about that. I found the shitty picture on the Kubota site and yes its worthless. A good picture of that valve might provide some insights.... This aint rocket science - you have a pressure source, a valve, and a cyinder. You can easily isolate the...

Well that was a waste of time. I could find nothing useful in the way of a parts diagram for the hoe or thumb. Got a picture of the valve? Is it a section in the main control valve? Dan

By my calculation thats 5,-6 tandem loads. Have them dumped in equally spaced piles across the area to be covered. Push and back drag to spread each pile. You can spread a pile in a matter of minutes and I would rough spread each one between deliveries. Finish grade after all the loads have been...

Actually I dont know but I will have a look at the parts breakdown in an attempt to educate myself. You seem to be indicating there is a relief valve just for the thumb which strikes me as odd. Is this a port relief perhaps? Dan

They have this thing called Google.... https://www.ebay.com/itm/363885964132 Dan

RPM is not going to help. A gauge is $20 plus whatever fittings but its probably going to tell you what you slready know - no pressure. My question is what relief are we talking about and why is it only the thumb with the issue? Dan

His takeoff but down the center along the side/top of the transmission. Of you want really neat and professional use steel tube for most of the run. Dan

Workshop manual is your friend. Dan

The Readers Digest version: With your current setup the C and T ports are interconnected and they are powering a downstream device - the 3pt The T core in the valve is not designed to handle pressures greater than 500-800 PSI and its also the backside of the inlet pressure relief so the...

Half inch JIC is 3/4-16 UNF thread. Even with a totally blown piston seal the thumb cylinder should produce something around 1500 pounds of extend force. Dan

It works but Prince would tell you its incorrect. I will forgo the long explantion of why for now. The correct way is to remove the plug in the "C" port and install the optional power beyond sleeve. Then move the hose currently connected to "T" to that sleeve. Lastly run a third hose from the...

The correct way to plumb the loader valve is with three hoses - the two high pressure lines you have and a separate low/no pressure tank return which on your tractor would go to the cap on thev hydrsulic filler. Post a couple pictures of the loader vslve so we can see if it has a power beyond...

Thats a DIY plumbing job. You can route NEW hoses of the proper length anyway you want. You seem to be using tank as power beyond. Might want to consuder fixing that. Dan

Dont over think this. If you can weld even remotely well stick some Grade 70 weld on grab hooks to the bucket AND forks. I prefer three as shown below. For a B2601 5/16 (8mm) chain should be all you need. You can turn grab hooks into slip hooks, D rings, or most anything else with a few links...

It does not matter if the tractor is running or not. With the remote valve in neutral the cylinder is held by 1) the seals in the cylinder 2) the spool in the valve. You can eliminate the cylinder by putting an inexpensive ball valve on the rod end hose connection to the cylinder. With the...

Why this is a mystery to any dealership escapes me. Might be time to invest in the proper workshop manual. https://www.mypartsguy.net/products/kubota-l47-m62-tl1300-tl1800-bt1000b-bt1400-tractor-front-loader-backhoe-service-manual Dan

Or just an ordinary tap drill to match the threads and pick the remains out. Quick and easy. Dan
