What part are you having trouble with?
I have had mine apart several times trying to repair a leaky valve.
Could possibly make a you tube clip.

SOURCE: Reassembling a crosman 760 pumpmaster airgun

The trick to assembling the trigger mechanism is to assemble the trigger parts on the left half of the receiver. This will leave the v shapped spring hanging out the bottom of the trigger guard. I assembled the barrel to the right side of the receiver and then but the two halves together. loosely attached the halves with the two long screws. I then used a jewlers screw driver to work and hold the end of the V spring behind of the safety button hole. At this point I inserted the safty button into the hole as I gradually removed the screw driver. Then clamped down the attachment screws.

I spent some 2 hours figuring this trigger assembly out and another half hour putting it together. The biggest mystery was the use of the L shapped part. It ends up being assembled to the trigger pin. the cleat catching the back of the trigger and the long side of the L laying against the left side of the receiver (pointing up). The small tention spring ingages the back of this L shapped part (just above where the cleat ingages the trigger) and the other end of the spring ( the straight end) rests against the bottom of the receiver.
