Backhoe Going to buy a #7 backhoe

You can also download the 750's operator manual from there to if you do not have one. I would attach it but my guess is that it will be to big at 38MB. On pages 37-41 it has the hydraulics info for it. The 7 BH manual also listed info in it as well.

If you go here you can see the parts https://partscatalog.deere.com/jdrc...lPTiwyOTE3OiNDQVRBTE9HLDY4MTAyOkVRVUlQTUVOVF0 This also lists out specifics with some of the simple drawings showing you the frame and how it would connect to the FEL etc.

Looking for a manual I could not find a match to this serial number.

This will show you your s/n ranges on the 7 BH https://partscatalog.deere.com/jdrc...oes__Introduction?a=1151&br=1061&locale=en-US

I never could figure out how those numbers relate to mine. LV0007X250168

Yes I believe the LV0007X have to do with the model number and then the 6 digits after is the s/n.

Well I finally jury rigged enough hydraulic hoses and fittings to finally see the hoe move a small amount.

But I had to unhook my loader.

Remember back in post #24 the pic I posted on how the bucket is connected? So I guess both of the top hoses has pressure. This Bush Hog loader has 3 hoses. 1 Pressure, 2 Power Beyond and 3 back to tank.

I assume the top hose in pic is pressure? the next one under it is power beyond.

Anyway I blocked the top outlet, connected the lower one to the hoe and it seems to work.

Now here is the weird thing. Back when my dad and I was hooking up the loader we couldn't get it to work, and somewhere before the internet I found some info where we had to remove a plug or install one inside one of the 2 outputs. Guess I can look tomorrow and figure it out.

And there is a learning curve figuring out hydraulic threads and fittings.

Ok, I found this. There is a plug in there so the loader will work.

Well 14 months later its actually bolted to the 750. All that is left is a few bolts in fenders and put new seals in the stabilizer cylinders.

I made my own front and rear hangers and modified the lower frame.

I ran into a big problem with 2 of the hinge pins in the bucket, they were completely frozen in place. 20 ton press couldn't do anything so I had to bore out each pin from each side as deep as I could go with drills and boring bar. What a nightmare. Case hardened pins. 4 days it took to get them out even with a 1/16" cutoff wheel on grinder.
I replaced 24 grease fittings. I dont think the dip s*^ts had EVER greased the pins.
