1970 3400; The hyd compression fitting at the pump started leaking again. I loosened the nut and pushed the tube back in but this time it will not stay in. This has happened before and I have had luck reinstalling. I understand the fitting is expensive at the Ford dealer but only around $10 on this site and on EBay. The EBay and Amazon reviews are not good. Has anyone used the fitting from this site and is there any special precautions I should observed during installation? As usual, your experienced consideration is greatly appreciated.

Buy it from New Holland.
There have been several posts about the cheap nut from this and other sites that does not hold.
It does not have the metal washer that crimps onto the tube and blows off immediately.
If you have the correct type on it now DO NOT work it back and forth to get the metal washer off. That will eat away at the OD of the tube and make it undersize so a new $40 nut will not hold either and you'll need a new $100? tube as well. To get the washer off carefully cut or grind it off.

Looks like the fitting is around $6 plus on this site. I think I would risk it and see if it works. Nothing ventured nothing gained.

Is this for the side mounted hydraulic pump for the 3 point lift, or the front mounted pump for the loader?

The fitting in question is for the side mounted pump for the three point lift.

Today's Featured Article - Two-Brush Generators - by Chris Pratt. Whether for product liability or because the aftermarket parts and labor business is lucrative, this concept is disturbingly prevalent. Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit ... [Read Article]
