S55 Hydraulic Gaskets

I was looking through my I&T Shop Manual and didn't notice this second gasket. Am I correct in thinking that it's unneccessary?

I was also having bad leak down and was assuming it was the cylinder o-ring. I am replacing it this round while I've got everything apart, but I also noticed that I was missing one of the flange gaskets where the hardline mounts through the pan to the control valve. Would this also contribute to my leak-down issue?

I bought a sheet of gasket material and have cut out a replacement for the pan gasket as well as the three flange gaskets. My local NAPA had a whole roll (3-ft wide) that they cut to length and sell by the foot, which came in very handy. By the way, I used a piece of .45 pistol brass and a .308 rifle brass to punch all of the holes for the bolts. Worked like a charm!

Thanks,

I also found a place locally (Borden, IN) that is an old AGCO/Oliver shop that still has TONS of parts and pieces for old Olivers. I ended up picking up another cylinder oring & leather back-up washer as well as new seals for the lift arms. They had absolutely everything you could imagine there (as far as standard stuff goes). Let me know if you need me to look for something. It's a couple of old brothers who run the shop and still do things the old-fashioned way. I'm headed back this after noon to settle up with them on the parts I bought because they didn't have the stuff to take debit/credit cards, and my wife doesn't trust me with more than a couple bucks. ;)

I stopped by again today during lunch (about a 15 min. drive from work) but they are closed on Thursdays (and Sundays). They've got a decent Super 55, two 1550s, and what I think might be a couple Super 77s along with a HUGE White sitting out front. Then there's another 77 or an 88 (I'm not good with anything but the 55s & 550s) sitting on one side with a 550 on the other, and sever models junked out back. I don't believe they have a 55/550 for parts, but who knows what's hiding in the weeds.

Next time I'm down, I'll have to snap a few pictures and post them.
