Okay starting to sort out the hose routing. I bought the kit from Fit-Rite Hydraulics.
Fit Rite Hydraulics - fitritehydraulics.com
The remotes and the two cylinders were received awhile back. Brian also sent me some orange 'test' hose to use once I mounted the remotes/cylinders. Taken me two years since life has been getting in the way. Anywhoos... I got the three point hitch mounted with the cylinders in place. According to the instructions, the tilt cylinder should be mounted on the right side. It also says to move the right OEM link over to the left side. I didn't do that and I am not sure why one should.
Edit: Check that... now I understand the OEM right side is an adjustable link, just swapped it out and put it on the leftside.
Unfortunately, but no biggie, this means for a little longer hose having to cross from left side where the remotes are.
The routing of the hoses from the remotes to the cylinders is a no brainer but not completely sure if I have the other 3 hose connections right. For you hydraulic knowledgeable folk, please look to see if I have it correct. A-A, B-B, C-C.
I understand from talking to Brian at Fit-Right, that it is possible to plumb such that the valves are always connected to the hydraulic circuit whether the backhoe is on or other implement that uses the remotes. Not sure if what I have shown achieves that. Look forward to comments!
Wondering also if I should post this for recommendations in the hydraulics forum?
