1863 3-pt --> 2084 hydraulics question
 

I am in the process of transferring the PTO from my 1863 parts tractor to my newly motivated 2084. I'm at the point of removing the lift link. I need to align the front pin with the frame hole to pull the pin out. However, there is no engine so I can't use the hydraulics to move it. It is locked in place. Do I need to bleed of system pressure so it will move? If so, where is the best place to do that?

Spin the driveshaft with a big drill

Interesting. I'll try that tomorrow.

EDIT: Looks like it will take a 3/4" chuck to grab that driveshaft. Biggest I have at home is 1/2", but I think I have a bigger spare chuck at the shop, and hopefully a 1/2" arbor to fit it.

Can you loosen the hoses to the lift cylinder and pry it to where you need it?

Just watch out for the hydro fluid that will leak out.

That was my first thought, but I didn't know where best to release the pressure. I don't guess it won't hurt anything if I loose all the fluid.

I'm going to go with the drill method if I can cobble together a big chuck setup. I'll do that today.

Just hold the raise / lower valve in the direction that you want the cylinder to go and force the cylinder to move by putting a wrench on the shaft circled in red in these pics.

That makes sense. I tried that early on, but my lack of conviction stopped me before I applied much pressure. I like that better than cracking hoses.

I'll give that a shot tomorrow AM.
If that doesn't work I'll crack the lines.

Thanks for the help!

BTW, the drill method was a good idea, but I could not find a way to spin that shaft. I have a nice big 18N Jacobs 3/4" chuck and a 1/2" arbor to fit it, but I could not remove the 3/4" arbor that was already in it.

Is the end of your input shaft threaded? If it is run a bolt in it, use a jamb nut and use a socket adapter in your drill to spin it CCW.
