Can anyone help me I.D. what Grumman aircraft these parts are from? I have had them over thirty years. (and they were old/used looking, even then)
The black & silver Grumman part ID tags read
Grumman Aircraft Eng. Corp.
Mfd. By EX-CELL-O Corp.
Part # 177550 & (stamped) 5 X G
Ser. # 849
INK-stamped in black on body: Ohauled Alameda, ASC 177 1966

Second one Mfd. by Chicago Pneumatic Corp
part # WT-1953 5 J

They are Heavy and at widest OD are 6 inches and approx 22 inches long, as in photo.

Looks like the shimmy dampers from a Connie nose gear..

Here is a listing of what I could find in the system:



Have no idea what it fits though, sorry!

10in of travel? oilcooler door actuator? flaps? undercart door?

Based on the piston diameter and the pressure, that actuator could put out 28,000 pounds of force. I'm guessing that it was from something big.

Hmmm.....they do look a lot like these don't they???? Found this here on WIX

Your cylinders sure do look familiar... and given your description and the visual I think they're the wing folding hydraulic pots for the F9F Cougar or Panther series a/c. The OH tags and the 1960s OH dates would be consistant with line service USN stuff ( I had a Cougar ejection seat with - get this - 1974 OH data stamps all over it! ).

I have a Cougar and Panther manual around here somewhere and will find it and cross-reference the part numbers for you. Lacking my ability to grab hold of the manual anytime soon, I'll check our hydraulic inventory here on the hangar shelves to gain access to the Grumman hydraulics we have and check 'em against that. I know for a fact we ended up with Panther and Cougar parts years ago.

Anyway, you get what you paid for - my two cents worth!

Thanks to all for attempts to help. I am hoping that Pooner can come up with a #s match to one of those planes, to finally identify where they came from. One other bit of info is that I got them with a lot of other aircraft parts, from a private/commercial shop that was very near to Grumman Calverton. on eastern Long Island. And they weigh about 30 lbs. each.Sure would like to know whch Grumman bird they came from.
Definitely different than the ones in the image shown by Wheels Up, above.

Thats actually one of the photos that I posted about the Grumman Tracker parts we have up for sale. I originally thought that you cylinder might be one for our tail retract system but the fittings and size don't quite match up. I also never remember seeing one quite like that in the Tracker but I could be wrong.

I was going out on a limb and keep guessing Panther or Cougar, but have come up kinda dry thus far on the tech manual support for the 177XXX series of parts.

I looked at my partial Panther manual this afternoon (NavAer 01-85FGA-504) to see what I could find. The Panther wing fold pots are p/ns:

134267 L 141505 L and 134267 R and 141505 R.

Your part has no L or R p/n from the data you provided in your query. But, the wing fold pots for this ship obviously had a change and revisions - manual cites both 141509 and 141509-1 as revision numbers with no L and R posting.

OK, still nothing CLOSE to 177XXX ....

Got to wondering about the tail skid pot... it's got a p/n of 140577-1. It's big and beefy, too....

Anyway, the Panther manual hydraulics section thus far shows NOTHING in a 177 p/n range. I will have to hunt for a Cougar manual ( I do not own one ), but can't imagine they completely re-did the hydraulics (but who knows?). This manual copy I have has nothing but line drawings of the parts, and while the illustrations are somewhat representative, they are not detailed and nor are they dead-on accurate.

Now, something of the same vintage makes me wonder - early S-2 Tracker? I will check that part number series for grins as well. But I thought we had someone check in who had some Tracker parts, and came up short. Lemme re-read the post...

You have me guessing so now I will have to dig in my pile to see what p/n's show up on my known Panther and Cougar stuff in the hangar. Bear with. We'll have a little fun with this and ID 'em yet!

In two weeks I will be back up at our hanger in VA and will paw through our manuals on the Tracker to see if there is anything in them.
