I recently purchased a bachoe and don't know what brand it is, it almost looks like ford under the old paint. it attaches to a tractor with 2 inch shaft up and down on hoe part. then it was on a ford tractor with big arms with a u cut out to hold the shaft. does anyone know what model and if it it is a ford,reason im asking I need a valve body for it, valve body is made by Hydreco. thank=you
 
It should have a tag on it something like this.

The Ford backhoes that attach that way are the 713 and 723 series -
late fifties to mid sixties, and the 750, 753, and 755 from mid
sixties to early-mid seventies. The 713/723 have the boom cylinder
enclosed in the boom, and the 750, 753, and 755 have the boom cylinder
external to the boom. My 713 backhoe has a hydreco control valve as
shown below from the parts manual.

thanks very much that explains a lot. my boom cyl is enclosed in boom so must be a earlier model. any ides where the tag is located I have not seen one? I suppose it is impossible to get parts for the hydrecdo control valve, any ideas.
 
Well ... it depends what parts you need. For a reseal job (which is
all mine needed) O-rings, quad rings, and wiper seals were available
as common parts from an industrial seals/packings supplier.
 
so for some reason this valve body has 3 broken spools, I assume they had water and froze or simply just broke. the body seems ok but with that much damage almost need another valve unless I could source spools. thanks
 
Even back in the day the spools were not "serviced separately" due to
the matched/precision fit. Below is a page from the service manual.

Probably next best thing to impossible to find an original valve, but hydraulics are fairly universal (generalizing) and it's not too hard to cobble on a valve off something else. I've got a 555B (IIRC) valve on my 723 after the original suffered a cracked body. Doesn't fit the stock brackets and had to adapt the fittings and controls some, but it's not that hard overall.

Another good thing to know of those hoes - the stock hoses use a flange O-ring seal (similar to how some auto power steering hoses seal) for all the hoses from valve to cylinders which is impossible to find anywhere. One company makes adapters from that to a JIC male, but they're pricey - $15+/ea IIRC. A much cheaper approach is to get JIB-10 bulkhead fittings and an O-ring (don't recall size offhand, OD of about 7/8" and ID about 5/8")
 
yews I think your rite I have done quite a bit of leg work with no luck.not saying there isn't a valve out there but where. too much else rite now to deal with it but will likely just put another settuo on it.
