I scored one of these interesting little rifles recently, and it was in need of a re-seal, so I figured while it was apart, I'd snap a few pics.
These guns are often referred to as being Crosman 160 copies, but there are enough differences between them, that IMO, "bearing a vague resemblance" would be a better decription.
I didn't get any pics before the teardown, so we'll start at the inside, and work our way out - lol.
The valve is similar to the later Cr 160, but I didn't check how close they were dimensionally. The only major difference in design is the piercing pin - instead of a shouldered pin, as on the 160, the Bobcat uses a straight pin, with a "C" clip to retain the valve return spring.
The bolt and hammer are very different on the Bobcat - far simpler than the Cr 160 - actually more reminiscent of the older Benjamins.
The safety is a manual unit - it does not engage automatically as on the earlier models of the Cr 160. I have seen pics of a Bobcat that had a mechanism of sorts protruding from the rear of the end plug/saftey housing, and my conclusion is that this is an adaptation to activate the safety as the bolt is drawn back. The small spring for the safety detent ball was not properly installed by the last person to take the gun apart, and as you can see, it was crushed, and requires replacement.
The trigger is very similar to the second variant Cr 160. Possibly due to the geometry of the trigger, but it seems to me that the Bobcat trigger is much lighter, and breaks more crisply than my second variant Cr 160. I'll be looking into this a bit more closely once I can shoot both guns side-by-side.
The end plug is a bit of a curiousity. The gun takes two powerlets, just like the Cr 160, but only the one facing the valve is pierced - the powerlet at the front of the tube is just "in storage" - there is no piercing pin in the end cap. Again, a "C" clip holds the unit together.
One other item of note on the Bobcat, is the barrel spacer. While it appears to be similar to the spacers that Crosman uses, the Bobcat spacer is made of steel. The top (that rests against the barrel) looks to be an extruded "U" channel, while the bottom, looks to be machined with a ball cutter.
Normally, it would only take an hour or so to do a complete number on a gun like this, but this one took a bit longer than normal due to someone, at some point in time, having squirted WD40 or some similar nasty stuff into the gun in an attempt to "rejuvenate" the seals. May have worked in the short term, but in the long term, it turned all the seals into a tar-like mush, which migrated all over the place under pressure - YUCK !!!! Many of the parts had to be soaked in lacquer thinner for a couple days to eliminate the crud.
I'll add some pics of the finished gun to this thread when it is done.
