Thank you! For anyone else trying to work this out, it seems the front hydraulic block has 3/8" BSPT ports (tapered threads), whereas a connector mentioned on the next page of the manual as a possible take-off point in the rear has 3/8" BSPP (parallel threads).

In discussing front end loader connections, the shop manual for my tractor (L3450DT GST) refers on page M.9-22 to "hydraulic take off adapters (screw size PT3/8)" . If ChatGPT can be believed, that's the same as 3/8" BSPT (British Standard Pipe Tapered, i.e. not 3/8" NPTF. Does anyone know if...

Thank you @TheOldHokie! That's great. The models have long alphanumeric names, depending on options. Here's mine: Cross DV102ACXYG0P13 DV10 = 10 GPM version (DV15 is the 15 GPM version). 2 Number of spools = 2 AC(Spool Type): A (1st spool): 4-way, 4-position, open center, float spool C...

I'm working on an LA650 front end loader, and just wanted to double-check that I understand the hydraulic connections. I bought a Cross DV loader valve for it and I want to connect the control valve to the tractor hydraulic block. The new loader valve has ports labeled A, B, C, D, IN and...

Thank you all for your answers. That makes sense.

@Lost_Jeep I have a slightly off-topic question: my tractor has a block that looks just like the one in your photo, and when I bought it mine had a plow attached with 3 lines to the control valve, like yours. The two hoses on the righthand face of the block are IN and OUT to the control valve...

Oh sorry @torch, I missed your in-line reply above. Thanks!

The loader uses mostly SAE hardware (fractions of an inch); however, anything bolted to the tractor itself in the subframe uses metric bolts. I imagine that the wedge bolt is subject to heavy shearing and possibly hammering forces as the end of the loader tries to move up and down, but only...

Thank you all for sharing your knowledge. The bolt is 5/8-18, I think. The hardening process sounds non-trivial -- for a "carborizing flame" can you use an oxyacetylene torch with an excess of acetylene? And if I looked for a machine shop or fabricator to make it for me, would it make more...

Thanks for your response, I was afraid of that. Looks like it should be only moderately hard to make, but I wish I had the specs.

I bought a Kubota LA650 loader that is missing the wedge bolts needed for mounting it to my tractor (L3450DT); the part number is 75540-56810. Messicks wants a fortune for them. I'm in the Pacific NW and would appreciate suggestions of any salvage yard that might have something like that (if...

I'm new to this, and I am wondering about tractordata.com in the context of finding attachments. For example, they show only one front end loader for my tractor (a 1980s L3450). Does that mean that other Kubota FEL's wouldn't fit, or wouldn't be recommended? How would I figure that out, and...
