Kubota GR2100 Lift Cylinder

[manvelman]

I am hoping to rebuild the lift cylinder on my GR but am having difficulty finding dismantling instructions for the cylinder. The holding pin on the right side of the plunging piston does not have an access hole in the frame for removal so I am assuming Kubota want you to dismantle some framework.
Can someone give me some suggestions.

I'm not sure that cylinder can be rebuilt. Others here will know.

According to the cross section @Bee-Positive posted that is a single acting displacement type cylinder. Nothing to rebuild except the rod packing (4). Is your cylinder leaking externally?

That cylinder can be rebuilt.
On a scale of DYI = 1 and Professional = 10, I'd give it a solid 8.5.
It's not easy to disassemble or to get parts for it.

From the quick search on line they're God Awful expensive new for the size of them.
Any recommendations for venders with reasonable prices? EDIT - never mind, I type too slow.

Maybe worth finding a local shop that can do it for less than the cost of new.

One more time - is it leaking externally? If not there is norhing to rebuild.

Given Kubota's usual pricing model $335 for a new one seems pretty tame.

Apologies for not being clear. The cylinder is leaking a lot. My question is not about rebuilding the cylinder but how to remove the cylinder from the mower. I am not able to remove The cylinder holding pin towards the rear of the GR.

Also, I am okay buying a new one but Kubota wants 4 hours ($600) for labor to replace which I thougt would be easy.

Looks fairly simple to me?
Pull 2 ring Cotter pins, then remove 2 cylinder pins.

Are you talking about the rod end of the cylinder, which pins to the bell crank?
Disconnect the linkage from the bell crank and rotate it until the pin is above the frame; remove the pin.
