titan np help needed

[jSan22]

OK, so I want to repair my crosman titan np. Problem is, crosman turned their back on me and a service shop wants $50 to do it. Internet searches turn up nothing.
The gun is very weak, and has a shifty poi. From what I read, If the powerplant fails, it stops working completely. However, it still works, but will NOT penetrate a plastic bottle at point blank range. So it could be seals. in that case, I could just build a compressor, tear it apart, replace the seals, and I'm done. But I wanted to make sure, and I posted this.

Thanks, I sent you a pm. Haven't ever torn down a break barrel before, ao its definitely not going to be a walk in the park like with the 1322. I sanded my stock and cut a chunk out the thumbhole and made it into a tactical style grip. I'd like a gun that I could use with it.
