Question about Crosman (4032)
It seems like the gasket is dry so I oiled it hoping it would solve the problem, but it hasn't. Does anyone know what to do?
If the rubber piston on the end of the piston assembly is missing, try this:
If the piston is still there, it may just have shrunk a little due to age or lack of oil. Drive out the roll pin at the top end of the pump tube, then remove the square-drive screw holding the end cap to the barrel sleeve. Be careful not to strip the threads here, since the barrel sleeve is just thin metal.
Remove the end cap and extract the fore-grip and piston assembly. Pull the rubber piston off the assembly and place the cupped end against a golf ball, then compress in a clamp or vise for 15 minutes or so to flare out the cupped end a little.
Check the fit, and if it pumps, reassemble. Worked for me.

Never use oil on the gun it will destroy the seals use automatic transmission fluid.If you go to Colemans web site and look up service centers you can call and get a seal kit for the gun for less than $20 and rebuild the whole thing.

I think it might just need oil . just get a fine air rifle or gun oil and put 4 or 5 drops in the plunger, and 2 or 3 in the place the trigger locks it back ,

By the way, I just took apart my 760 (2nd variant) and looked for a seal kit to replace everything. Kinda overpriced almost everywhere. I called the Crosman co. They patched me through to their customer service...I got the following parts for around 14.50 (that's with shipping). 130-034, 130-035, 140-058, 130-057, 1400a029, 1322D020 (used to be C, but they changed the part # to D) the following part were obsolete - 760-050 (brass nut goes on the bolt action), 760-037, 111a026 (standard spring). Hope this helps.
