That would be my first thought
our air pressure is going to be so small compared to working hyd pressure, I don't see it harming anything where ever you apply it.. This looks much like , but not exactly, the hundred series, so I expect the hole you are after is the only one not it the row with the other 5.(quoted from post at 13:36:04 04/17/20)
I removed the lift cover with the cylinder attached. The piston would almost fall all the way back as far as the rod would let it, where the seal was pretty much gone as you can see. To remove the piston I had to unbolt the cylinder from the lift cover 4- 5/8 bolts in the center. Then I unhooked the armature and separated the two. Turned the cylinder up and piston pretty much fell out. No scarring and looked good inside.
The problem I'm having is a NH dealership sold me a 4000 oring which fit and told me it would be fine. And they didn't have a new backup ring for that oring. The backup ring looked to be ok so I stuck it back together. The spacing /gap didn't look to bad on the backup ring. But the old one did blow out at that gap. So I decided to by a new one and go ahead and replace that old one. And according to the parts diagram that oring for a 4000 is a lil different size than a 4610 if i read so correctly? I spent 100 dollars on all new seals for the lift cover and remote covers. So I don't wanna take the chance. I went ahead an ordered the correct part numbers oring and backup ring.
Now I need to remove that piston with a new seal. I don't wanna damage anything in doing so. I'm not sure where to blow the compressed air? There are 6 holes/seals on the cylinder that seal to the lift cover.
