70A Loader oil lines

[Mechanos]

I just aquired a 70A and there is some goofy stuff going on with the oil lines on the cross tube. Can someone with a 70 or 70A post up a pic of the oil lines so I can compare to what's on mine?

Thanks....

Is this what you need?

Mech, can you post pictures of yours? Have you looked in JDParts?

Is this what you need?

Yes, that's exactly what I needed. I really wish people that don't know what the **** they're doing would just stick their hands in their pockets and walk away.

Kennyd,
I'll try to get some pics.... but it might be a few days. Basically, it looks like someone damagage the hard lines and then tried to "repair" it by replacing them lines that aren't quite the right application. So, they are all bent around in crazy angles and just looks like a "baling wire & duct tape" fix. Then, someone did it again... it look like they wrapped a chain or something around the cross tube to either lift something with the loader or lift the loader itself and all four of the oil lines are crushed flat in that spot.

I did check the JDParts, but with the exploded view it is hard to tell how that are all arranged and "packaged" on the cross tube. Also, looking at JDParts, they want $135/each for the "Short Oil Line". :confused2: At those prices, I would almost be better off to through the loader away and buy a new one. :laughing:

I just got off the phone with a local hydraulic shop that does tube bending, hose repair, etc. I described to them what I had and he told me no problem... we can probably even do that for you while you wait. So, when I get a chance, I'm going to pull the lines off the tractor and take them to the shop to be repaired.

Bet I know what happened because I did it to my 80A loader cross tube lines.

If you use the JD front suitcase weights on the front weight bar, they can interfere with the oil lines when raising the loader frame. The lines get pinched and crimped and that's a problem.

I modified the front weight bar to get it closer to the radiator. My lines are still a bit smooshed, but the price is too high to replace them.

I suppose the suitcase weight theory is a possibilty. Two of the lines look like the weights could have caused the damage. The other two lines look like they were used as training aid in a blacksmith class! :laughing:

I did notice an interesting difference between the oil lines in JD755's picture and the oil lines on my loader. If you look at the T fitting in JD755's pic, you can see that the fitting block is made onto both sides of the oil line making it a one piece line. On my loader, the fitting block is only made onto one side and the other side attaches with a threaded fitting.

This is fortunate for me, since I only need to replace the part of the lines along the cross tube that are damaged. This will be quite easy for the hydraulic shop to make. Why, for Pete's sake, some knuckle head felt compelled to bend the **** out two of the lines and then put a dog-leg in two of the cross tube lines to meet up with the contorted lines is completely beyond me.

I am going to try my best to bend those two lines back into their original shape and just have new cross tube lines made up at the hydraulic shop.

Mech,

Do you want some photos of the lines on my 955?

Mech,

Do you want some photos of the lines on my 955?

Sure.... it can't hurt anything to see more pics.

 

[955er]

Here you go.

 

[955er]

Sorry, did not take.

 

[955er]

Try again

 

[Mechanos]

Thanks.... hard to tell in your pics, but are your oil lines one piece or two piece?

 

[955er]

Two piece. I can get a close up if you want. Just tell me what you need.

I have been following your threads over the last couple of months. You should have one fine tractor when you are done butchering up the other two

Mine has 910 hours and the only piece I replaced was the muffler. The bracket cracked. $250. Save those...

 

[Mechanos]

Thanks 955er.... that should do it.

Had some free time today, so I took the oil lines off the loader. I see now why the PO bent the upper oil lines all out of shape. Two of the lines on the cross tube were not the correct part for the application... they must have come from a different loader. They were too long. The PO's "fix" for this was to bend a dog-leg in them to take up the extra length. Of course, now they do not terminate in the proper location so he then bent the upper lines all out of shape to get them to meet those two lines on the cross tube.

I'm going to try to make it by the hydraulic shop tomorrow. I will need to have all four cross tube lines re-made. I tried to straighten the two upper line and return them to proper shape, but they were too far gone. The tubing was bent too much... to the point of work hardening and both of them cracked right at the fitting block on the ends. I will have to have both of those lines repaired as well.

Dropped the oil lines off at the hydraulic shop and told them what I wanted done. When I got the quote, the color drained from face. The counter guy could sense my state of near cardiac distress and offered to discount the price from $440 down to $310. That's still a LOT more than I was expecting it to be, also a heck of a lot cheaper than ordering all new lines from JD for a few dollars less than $600.
