it depends on the model. See the link below and select you model to see the diagram.
The pump is a pull-down located on the barrel, and the 12-shot loader is a cylinder integrated in the gun just past the trigger mechanism and before the barrel. I've tried dismantling it, but to no avail. the air cilinder (located on the barrel) does not seem to touch any of the springs associated with the firing/trigger mechanism. Blocked? or a missing part that fits into the air cylinder If someone can explain how the mechanism works i can see if everythings there. thank you.
Crosman started making the Raven's in 2008.
See the link below. It may help you.
Get a GR3T trigger for it. It is considered the very best trigger available for Gamo. See the link below
If there are any they usually are on the barrel close to the loading breech or above the trigger.
See the Crosman link below.
When the rifle is cocked, a spring is compressed. Pulling the trigger releases the spring, which pushes a piston forward, The piston compresses air as it moves. The compressed air blows the BB or pellet out of the barrel.
Their are 4 common types of air rifle power plants. Spring power: or Nitrogen piston power. this uses a large spring inside an air piston tube; When the barrel is cocked (Commonly called a break barrel rifle) the spring is pushed back in the piston chamber and locks. A pellet or BB is loaded. When the trigger is pulled it releases the spring, forcing the piston forward in the air piston chamber, Compressed air fires the pellet out the barrel. C02: a C02 cartridge is loaded into the rifle and acts as a small air chamber releasing some C02 each time the trigger is fired. Eventually the C02 is used up and has to be replaced. Pump power. simply you pump the forearm on the rifle and it fills an air tank. When you have enough compressed air you fire the rifle PCP: Pre Charge Pneumatic: This is a large air tank inside the rifle. It is charged with a bicycle pump or scuba tank. It's like an oversized C02 tank inside the rifle. Again each time the trigger is pulled the tank releases a burst of air behind the pellet to fire it out of the barrel. This type of air rifle is usually a very high-powered rifle.
Yes it can but getting the current rifle "Tuned" by an expert will get you better results. Tuning will make the spring and trigger perform better.
I would contact Diana directly at the link below and see if they will send you a diagram.
