Have a 162 EI, the small o-ring that is on the pellet probe seems to have a small slit in it.
1. Is this common
2. how hard is it to replace? (do I have to take that probe out or can I just slip a new one on?
3. What is the o-ring size?
thanks

Morini o-ring;
The crack is definitely not normal. The part No. is 162027A. It is a 3.5 X 1.2 metric o-ring. Should be available from www.airgunsonly.com. A good way to test for leaks is to drape a piece of toilet tissue or similar over the breech, load a pellet and fire. If the tissue jumps you have a leak!! Good luck.

O ring
The O rings do wear. As a rule I re-seal my air pistol every 12 months.
To test for a breech leak, hold a lit match close to the breech and fire a pellet, a small leak will make the flame flicker, a large leak will blow out the match.
Replace the O ring for a large leak.
Remove the grip, remove the back strap and spring, remove the side cocking lever.
The loading pin is retained in the frame by a pin (the one that slides in the slot on the L/H side), on the R/H side of the frame there is a hole that will allow a small pin punch to tap out the crosspin and then remove the loading pin out the back of the frame.
Replace the Oring and lubricate, re install the loading pin (the right way up), tap the crosspin back in. DO NOT tap it in too far as it will jam up on the other side of the frame and may not allow any movement.
Re assemble back strap with spring and fit grips.

Re: O ring
Thanks I'll give some of this a try today.
I did as the other poster suggested, I contacted www.airgunsonly.com and the guy there sent me a couple o-rings for free and I didn't even buy the gun from him.
