Couple drops of Secret Sauce on the rubber cup and linkage pivot points.

Pretty easy. Knocking roll pins in and out is probably the hardest part.

Think of an oversized1377. Only difference, the 392 has 2 o- rings instead of a transfer port seal.

Update...I dont think this gun needs a valve...I believe it dried out and in my zeal to get it pumping I fouled the tube with oil .....but since its tore down will go ahead and clean and install new valve when it gets here.....what the heck its a learning experience...

Is the old valve brass or aluminum?

To begin with Gun would not pump up...after a though cleaning ...I replaced the aluminum valve with new style brass valve...gun would still not pump up...fortunately I also ordered a rubber piston...gun is working as it should....thanks for the replies...

I think it was a matter of gun being dry (brothers gun)...but I may have over oiled it ...as  it would pump up but quit...I will say this there is a marked difference in the new piston rubber vs the old....Im waiting on some sheridan pivot pins...just incase I have to go back in....they may be fugly but I hate bangin on these guns...
