B7200DT with B1630 loader - 3 hours east on the turnpike. Dan

Welcome to the world of dealer parts. Take one of the couplers out of the housing and look for a laser engraved or etched OEM part number. I got a Lincoln that says they are Faster couplers - probably model number PV or CPV. Dan

Close but no cigar. Ypu need to purchase and install the P40G power beyond conversion sleeve from Summit. https://summit-hydraulics.com/product/power-beyond-adapter-sleeve-for-p40g-series-summit-monoblock-valves/ Remove tye steel plug in thevN port on the valve andd install thatvsleeve. Then...

Its your tractor - I am sure you will do whatever you want. But the loader valve you're replacing is an ADDITION to the tractors hydraulic system and it was done incorrectly. Yes it has worked all these years but it's old and it could malfunction and stick closed tomorrow. If that happens it...

Strange - that outlet block looks vaguely familiar.... Dan

SuperTech Heavy Duty THF is produced by Citgo. Big Oil versus Big Retail in a squeezing match. That would be worth the price of admission. Interestingly I stumbled on this while looking up the source for Wallyworld THF. Looks like Ciitgo has a J20D/SUDT2 clone. Mighty fine looking PDS. I will...

I was impressed by how close it was when I researched it but I could not find a source in the USA. Keep in mind these viscsoity numbers are not exact specifications. KV40 is used to grade hydraulic oil. ISO 42 has a KV40 viscosity in the range 38cSt to 46cSt. ISO 68 would be 61cSt to 75 cst...

The power beyond circuit is a loop through ALL of the valves invloved. It starts at the hydraulic outlet block and ends at the 3pt. The control valve on a BH76 should never be used to feed another valve. The return line is actually a PB feed to the 3pt valve which is disabled when the backhoe...

I have a far more detailed and much more trustworthy analysis from Infineum that covers multiple house brands. What it revealed is that with the exception of the yellow bucket crap they were all decent GL4 level gear lubes. Some better than others. The yellow bucket crap was horrible and...

My UDT data is the is from 1998 and that difference in KV100 viscosity is not significant. Chevron AW THF Is supposed to be a J20D fluid. Good luck sourcing it. Same issue with CNH Ulraction. And if you do find either they will be more expensive than SUDT2. JD Hytran J20D might be a little...

No. Dont know what model backhoe you have but most of them must be last in the loop. The proper circuit would be: Loader PB to P on 3rd function. T in 3rd function to P port on Summit remote valve N port (with PB sleeve) to backhoe coupler T port on Summit valve to any tank return. That is...

I have friends in high places :) I have posted that chart (my creation) before along with this link. https://www.sae.org/publications/technical-papers/content/972788/ I made my living as a researcher and data is what drives my thinking. When I was working I could get access to SAE...

No - I am telling you to follow Kubotas guidance on adding hydraulic implements to that machine. They make it crystal clear the FIRST valve added using that hydraulic blocjk must have an inlet pressure relief. Its your machine.... Dan

As do thousands of other equipment owners. Go read this John Deere blurb. According to them JD Hygard is the only thing you should use in JD equipment. Why? Bercause it undergoes more tests than competing formulations. Shades of Spinal Tap and their special guitar amplifier with a volume knob...

What is so complicated about adding a tsnkbreturn hose to that plumbing? It needs to be done if for no other reason than your current setup could easily malfunction and destroy your tractors hydraulic pump. Dan

If you can mix milk and honey and come up with a 9 cSt hydraulic oil with GL4 gear oil performance you are an alchemist. There are no industry standards for UTTO or hydraulic oil but there are dozens of industry standard tests authored by API, SAE, JIS, ASTM etc. When Kubota goes shopping for...

Assuming you are talking about the SSQA mount they bend like toothpicks. Put the bent side up against a big ass tree and use hydraulic and traction power to bend/twist it back. Then make a mental note that you will quickly forget to not do that again. Dan

With all due respect thats picking nits. Mobil 1 10w30 is a different formulation than Castrol GTX 10W30 but in the same grade and API service class they are interchangeable. They meet the same basic specifications. Same wuth UTTO. They are API GL4 gear oils with a KV100 of around 9.2 and VI...

Yeah - and no pressure relief is a much bigger issue than using tank for power beyond. With the new valve that's getting fixed as well. You will need to purchase or more likely make some sort of tank return fitting. Being a machinist that should not be much of a concern..... Dan
