I have a Benjamin Sheridan model 397PA in .177 cal.
This design has been around for decades. It used to be called the "Blue Streak". It is a multiple pump rifle. I bought this one 2nd hand, don;t know the mfg date but it's new enough the serial number is dot matrix engraved.
Anyway it has developed a problem - try to pump it up and it generates little or no pressure.
I removed what I think is the valve assembly. It's a brass cylinder 3.33" long and .77" diameter. It has an o-ring around both ends. The o-rings are flattened on the OD but no cutting or chunking.
I've been looking at parts on PyramidAir. There appears to be a kit which consists of 2 or 3 o-rings for this valve. Looks to me like there's an o-ring on the piston and one on the bolt but Pyramid does not offer these.
Brings up several questions I could use some help with.
1. Anyone resealed a valve like this and was it successful?
2. Did Crosman buy out Benjamin Sheridan?
3. If I bought a new Model 397 does Crossman sell all parts if it breaks?
Thanks
